  MegaPaint is an Image Editor...

 MegaPaint, version 1.1, is a powerful image, icon and bitmap editor. Working with SuperLogo, MegaPaint lets you create or modify images, that is, values of image variables, or shapes of turtles. It can also create or modify .LGW files, .ICO files, and .BMP bitmap files to a maximum size of 255 x 255 pixels. MegaPaint provides several basic and advanced tools like drawing and filling, writing text in any font, style, colour and size into graphics, inserting basic regular geometric shapes (lines, circles, rectangles, ellipses, filled ellipses), works with the standard Windows Clipboard, shrinking & growing, reductions, rotations, colours replacements etc. It also provides a special Frame Animation Window for developing animation - that is, sequences of frames in an image. It also helps you make your own Windows-like buttons. It supports two filling methods and many other advanced graphics operations.

  Zoom Area

  Tool Bar

  Zoom Area

The major part of the MegaPaint Window is covered by a zoomed version of the currently edited frame of an image. Each pixel of the original frame - which you see in the Frame Preview Area - is shown as a coloured square. Its colour is the actual colour of the pixel. Beside palette colours, two special colours can be used here - transparent and inversion. Within this area you create or change the frame by clicking the squares with mouse to change their colours, by filling areas, by copying, cutting, or pasting graphics etc. You can also choose any colour used in the Zoom Area to become the foreground or background colour by holding the Ctrl key and clicking the colour in the Zoom Area with the left or right mouse button.

The number of squares in the zoom shows the size of the frame currently displayed. The smallest frame is 1 x 1 pixel, the largest one is 256 x 256 pixel (its width and height can be different, for example 5 x 200). Different frames in an image can have different sizes.

Basic Definitions - Transparent and Inversion Colours...
Transparent and Inversion Colours...

are two extra colours added to the basic palette of 16 colours or to the extended palette. The transparent colour gives you transparent areas in your images. Areas coloured by the inversion colour will invert each pixel behind them - for example, pixels on the SuperLogo graphics screen.

In the zoom area, transparent pixels are displayed as white squares with four black dots inside. Inverted pixels are displayed as black squares with four white dots inside.

Large Frames are Zoomed...
  Large Frames are Zoomed and Previewed...

in a different way. The biggest zoom can display only 76 x 76 pixels (if you set the grids size to 4, see the Editor Options dialogue). Therefore, if the frame is bigger (either wider or higher), only part of it is zoomed and the horizontal and/or vertical scroll bars are displayed in the Zoom area. In this case, the Preview Area displays the whole frame together with a rectangle which shows which part of the frame is currently zoomed. The mouse cursor in the Preview Area changes its shape into a black right angle. If you press the mouse button here, the position of the mouse will become the upper left corner of the part to be zoomed.

Here you can see a Preview Area of a frame sized 207 x 209 pixels.

If you select the Extended Palette option in the Editor Options dialogue, the basic palette is extended by two extra rows of colours. By clicking colours in the Palette, you can choose both the foreground colour and background colour. When you start the MegaPaint editor, the foreground colour is black and the background colour is transparent.

  To choose a different foreground colour, click the left mouse button on any colour in the Palette. The left rectangle in the Colours Replacement Area will show the selected foreground colour.

  To choose a different background colour, click the right mouse button on any colour in the Palette. The right rectangle in the Replace Colours Area will show the selected background colour.

You can also choose any colour used in the Zoom Area to become the foreground or background colour by holding down the Ctrl key and clicking that colour in the Zoom Area with the left or right mouse button.

If MegaPaint is in selection mode and you select an area within the zoomed frame, then clicking the arrow button will replace the colour of all foreground colour pixels (within this area) with the background colour. If MegaPaint is in drawing mode or filling mode, then colour replacement will take place for the whole frame - even if it is not all displayed in the zoom.

If you select the Use Actual Colours option in the Editor Options Window, the foreground and background colours will also be used as the two colours for a newly created button frame, see Add Button Frame (pressed) and Add Button Frame (released).

  Starting MegaPaint

MegaPaint can be started either:

as a stand-alone Windows application (from the Program Manager window) by double-clicking its icon, or by clicking the icon and pressing Enter,

from the SuperLogo Memory Window if you want to create or modify an image variable. There are four ways do it:

With menu command: Edit - if the object already exists,

With menu command: Add Variable - if you are going to create a new image variable. The Add Variable dialogue box appears asking for the name of the variable. You also have to check the Image Value option there,

With a mouse shortcut: double-click the working area of the inspection window of the object if it is currently open.

With a shortcut key: F11

from the SuperLogo command line with EDIT if you are going to modify an variable image which already exists,

from the Make Turtle Chooser in SuperLogo,

from the Change Turtle Dialogue in SuperLogo.

If you start MegaPaint to edit an image which already has more than one frame, the Contents Window opens first.


  Quitting MegaPaint

If you started MegaPaint as a stand-alone application, it can be closed by:

pressing F12, F2, Shift+F2, Alt+F4 or choosing Save and Close, Save As, Close MegaPaint, or Save in its File Menu. These commands differ from each other depending on whether the edited image has (or has not) been named and has (or has not) been changed.

If MegaPaint was started from SuperLogo, you can close it by:

pressing F12 or choosing Save and Close in the MegaPaint File Menu. The image variable you were just editing is automatically updated in the SuperLogo Memory Window (that is, in the Logo memory as well),

pressing Alt+F4 or choosing Close MegaPaint in the File Menu. If the contents of the Editor have been changed, you are asked whether they should be updated in the Logo Memory as well,

through the standard MegaPaint Window's control menu.

In this case, the hot spot of the frame is also flipped. If MegaPaint is in the selection mode, the Flip Horizontal tool can only be used if a rectangular area has already been selected within the frame. In this case the hot spot is not flipped, even if you select and flip the whole frame.

  Tool Bar Button:


   Flip Vertical

This command flips the displayed frame (or a selected rectangular part) from top to bottom. If MegaPaint is in drawing mode or filling mode, it will flip the whole frame. In this case, the hot spot of the frame is also flipped. If MegaPaint is in selection mode, the Flip Vertical tool can only be used if a rectangular area has already been selected within the frame. In this case the hot spot is not flipped, even if you select and flip the whole frame.

  Tool Bar Button:


Slant Region
   Slant Region ...

To learn more about any part of this dialogue, click on it in the picture with your mouse.

If MegaPaint is in selection mode and you have already selected a rectangular region within the displayed frame, Slant Region opens the Image Slanting dialogue. Here you choose the angle by which the region should be slanted. The surrounding background of the slanted region will be filled with the background colour, that is, the colour currently selected and displayed in the right-hand rectangle of the Colour Replacement Area.

  Tool Bar Button:


   Shrink & Grow...

To learn more about any part of this dialogue, click on it in the picture with your mouse!

This command is used to change the size of a frame (or a selected rectangular part) together with its contents. That is, the contents of the frame is changed so as to shrink or grow together with the frame size. Compare this command with Size, which changes the size of the frame, but doesn't shrink or grow its contents.

When you select this command, the Shrink & Grow, dialogue box opens with Horizontal size (x) and Vertical size (y) text boxes. There you choose a new width and height for the frame or the selected area.
If MegaPaint is in selection mode, the Shrink & Grow tool can only be used if a rectangular area has already been selected within the frame. If you shrink the region, the surrounding background of the selected area will be filled with the background colour, that is, the colour currently selected and displayed in the right-hand rectangle of the Colour Replacement Area.
Be careful:  shrinking or growing a frame may partly change the shape of its contents, you may have to fix this afterwards with the MegaPaint drawing tool.

Sets the size of the displayed frame of an image. Opens the Frame Size dialogue box in which you specify the width (horizontal size) and the height (vertical size) of the frame. However, the contents of the frame is neither shrunk nor grown. If you enlarge the frame, its original contents remains in the top-left corner and the new area is filled with the background colour, that is, the colour currently selected and displayed in the right-hand rectangle of the Colour Replacement Area. If the size of the frame is reduced, the original contents is cropped from the right and bottom.

  Compare with Shrink & Grow...


  Hot Spot...

To learn more about any part of this dialogue, click on it with your mouse.

When Hot Spot... is chosen, the Set Hot Spot dialogue box opens in which you set both X and Y co-ordinates of the hot spot. The location of the hot spot is displayed in the right-most part of the Status Line.

To redefine the hot spot's position, you can also:

  select Hot Spot With Mouse command,

  click with the left mouse button on the right-most section of the Status Line to open the Set Hot Spot dialogue,

  click with the right mouse button on the right-most section of the Status Line to set the hot spot of the frame, see Hot Spot With Mouse.


Hot Spot With Mouse
  Setting the Hot Spot With the Mouse

If you want to change the hot spot of the frame in the Zoom Area, you can select the Hot Spot with Mouse command. The mouse cursor will change into a small box with an arrow. Now you can move it and click a point in the Zoom Area which will become the new hot spot.

You can also click with the right mouse button in the right-most section of the Status Line. The mouse cursor will be changed so that the point which you click in the zoom area will become the new hot spot.

However, you cannot put the hot spot outside the frame by using Hot Spot With Mouse. To do that, select Hot Spot and specify the new location in the Set Hot Spot dialogue box.


Show Grid

If this option is on (which is the default), the zoomed version of the currently edited frame of an image has a grid of lines which clearly separate its pixels. The grid is not a part of the frame itself and is never displayed in the Preview Area.

If you turn this option off, the grid is not displayed in the Zoom Area. To change the size of the grid, use the Grid Size option in the Editor Options Window.


Zoom In

If this option is on (which is the default), the edited frame of an image is displayed zoomed in the Zoom Area and previewed in the Preview Area. If you turn this option off, the Preview Area will be empty and the frame will be displayed un-zoomed in the Zoom Area only.

  Shortcut Key:  F8


Fill: Chessboard Fill

This option is not usually selected. If you turn it on, each fill operation will cover the whole area with the same colour surrounding the click point with a chessboard pattern using the foreground and background colours.


Fill: Diagonal Fill

If this option is turned off (which is the default), a standard filling method is used by the MegaPaint image editor. If you turn it on, a non-standard method is used: if two pixels of the same colour are only connected diagonally, they will still both change to the fill colour when the Fill tool is applied to any of them. By using this filling method, diagonal lines can be re-coloured.


Button Shape: Use Actual Colours

When you start MegaPaint, this option is not selected, which means that whenever you use the Add Button Frame (released or pressed) tools, white and dark grey colours are used to create the inner frame of a new button.

However, if you select this option, the foreground and background colours will be used instead of white and dark grey.


Button Shape: Use Pen Width

When you start MegaPaint, this option is not selected, which means that whenever you use the Add Button Frame (released or pressed) tools, a white and dark grey frame is created within the frame (or its selected rectangle) with the fixed width of 2 pixels.

However, if you select this option, the pen width will be used to specify the width of the inner frame.


Palette: Extended Palette

Normally, this part of Editor Options is off. However, if you select it, two more lines of colours are added to the Palette Area containing some additional colour buttons (if the image contains more than 16 basic colours) or empty buttons. Two small arrow buttons are used to scroll through all other colours used in the image.

If you press and hold the Ctrl key and click any filled additional colour button (or the first empty button), the standard Colour Chooser opens. Here you can make an RGB colour for that particular button.

To see and change the image's complete palette you have to press [image] to open the Palette Window.


Palette: Raster Colours

If you are working in standard VGA 16 colours graphics mode, this option is disabled. However, if you are working in modes with more than 16 colours (256 colours, 65 536 colours, or True Colour), this option sets the way additional colours in the Extended Palette should be created.

If the option is not selected, additional colours are solid colours (extending the basic 16 colours). If the option is turned on, additional colours are created as non-solid colours by combining the 16 basic colours.

Size-of-the-Frame Window

The second item in the Status Line, it displays two numbers X and Y (separated by a small x). These numbers are integers between 1 and 255, inclusive, and they show the width and height of the displayed frame (of an image being edited).

The size of a frame can be changed with Size... (without growing or shrinking the contents itself). The contents of a frame can be enlarged or shrunk with Shrink & Grow....


Mouse Cursor Position

The last but one item in the Status Line, it displays the actual position of the mouse cursor (when the cursor is located inside the Zoom Area). These are two numbers X , Y, where X is between 1 and the width of the frame, inclusive; and Y is between 1 and the height of the frame, inclusive. Position [1 1] refers to the top-left hand corner of the frame.


  Draw Button

This button sets MegaPaint to drawing mode (stopping other modes like filling mode or selection mode or line mode etc.).

If MegaPaint is in drawing mode, whenever you point at a pixel in the Zoom Area with the tip of the mouse drawing cursor and click, it is coloured by the set foreground colour:

  if you click there with the left mouse button, the square is coloured by the foreground colour,

  if you click there with the right mouse button, the square is coloured by the background colour.

  Tool Bar Button:

  See also How Foreground and Background Colours Are Selected


  Fill Button

This button sets MegaPaint to filling mode (stopping other modes like drawing mode or selection mode or line mode etc.).

If you press this button, the mouse cursor changes into a special "filling pen" with a tip. Whenever you point with the tip of the cursor at a pixel in the Zoom Area and click, the whole region surrounding the point (and the same colour as the pixel clicked) is filled with the new colour:

  if you click there with the left mouse button, the area is filled with the foreground colour,

  if you click there with the right mouse button, the area is filled with the background colour.

The region is defined either in a standard way (like in Paintbrush) or - if you turn on the Diagonal Fill option - also points of the same colour that are connected only by their corners (not by their sides) are filled. If the Chessboard Fill option has been selected before the fill operation, the region is filled with a chessboard pattern using the foreground and background colours.

In the Text edit box you type your text which is immediately displayed in the selected font style and size in a small preview window. When you press OK, the dialogue box is closed and your text is put onto the Clipboard. At the same time the text is inserted onto the currently edited frame of an image and its position can be changed by dragging it around the Zoom Area.

The text created in this way will be in the foreground colour with the selected background colour as background, see Colour Replacement Area. If the background and foreground colours are set the same, the Insert Text dialogue will not produce anything visible and cannot be opened until one of these colours is changed.

  Tool Bar Button:


  Select-an-Area Button

This button sets MegaPaint to selection mode (stopping other possible modes like drawing mode or filling mode or line mode etc.). Selection mode makes it possible to choose a rectangle in the Zoom Area to which the next action will be applied.

If you press this button, the mouse cursor changes into a cross. You press and hold the left mouse button to set one corner of the rectangular area. Then you drag the cursor to the opposite corner of the area you want and release the mouse button. An area chosen in this way remains surrounded by a rectangle which can be:

  dragged to any place within the same frame - its original position is filled with the actual background colour,

  cut or copied onto the Clipboard,

  tilted, flipped, rotated, re-coloured etc.

  Speed Bar Button:


  Browse Through the Frames of an Image

On the MegaPaint Speed Bar there are two buttons with a left arrow and right arrow, and two small windows: the right one displays the total number of frames of the currently edited image, the left one displays the number of the frame which is actually displayed. These two buttons allow you to browse through the frames of the image: if you click the left arrow button, the previous frame is displayed, if you click the right arrow button, the next frame is displayed.

If the image has lots of frames and you want to move quickly through them, it is easier to do it in the Contents Window.

is a temporary storage area in the Windows memory for copied or cut user-defined objects, text or graphics. You can make use of the Clipboard to move parts of frames or whole frames from an image within MegaPaint, you can import small graphics from other Windows applications into the MegaPaint etc.

Parts of graphics are always put onto the Clipboard with Cut or Copy. The Clipboard holds the information until you cut or copy again. The contents of the Clipboard is placed at a new location with the Paste command.


Cycle ...

is a check box which sets whether or not the last frame of the sequence will be followed in the animation by the first one. Or, if you select Reverse Order, whether the first frame of the sequence will be followed by the last one.


Reverse Order ...

is a check box which sets whether the sequence of the frames will be animated by displaying them in normal or reverse order.


Speed ...

is a scroll bar which sets the speed for displaying one frame after the other when they are animated in the Frame Animation Window.


Window ...

Here the frames of the edited image are displayed one by one (in normal or reverse order). The speed of this is set by the Speed scroll bar. The position of frames within this window can be adjusted with horizontal and vertical hot spot position markers.

Any time you double click this area, a small 16 Colour Chooser opens. Here you can choose any colour to become the background colour for this animation area.


Hot Spot Position Markers ...

are two markers - a vertical and a horizontal - which set the hot spot location of the frame displayed in the animation window. Both of them can be dragged with the mouse.


Horizontal / Vertical ...

Here you set X and Y co-ordinates of a point which will become the new hot spot in the frame. The top left corner of the frame is

The image to be inserted can have more than one frame.


Insert After

If you click this button, the last image copied to the Clipboard - either from MegaPaint or elsewhere (for example, SuperLogo), will be inserted after the currently selected frame.

.

The image to be inserted can have more than one frame.


Size

This inspection window tells you about the size of the currently selected frame. If more than one frame is selected, the information belongs to the most recently selected frame.


Frame

Here the sequence of all the frames of the currently edited image is displayed. One or more frame can be selected here, copied to the Clipboard with the Copy button or the contents of the Clipboard can be inserted into the sequence.


Copy

If you click this button, the currently selected frames are copied to the standard Windows Clipboard. (The format is LGW.) Later they can be pasted from there either into MegaPaint with the Insert Before and Insert After buttons, or elsewhere - for example, into SuperLogo.


Delete

If you click this button, all selected frames  displayed in the Contents Window will be deleted.


Program Groups

This list box contains the names of all program groups installed in the Program Manager. If you select one of them here, a list of the group's items will be displayed in the list box.


Program Items

This list box displays the names of all applications installed in a selected Program Group in the list box. Whenever you select a program item in this list, its current icon is displayed above the new icon.


Actual Icon and New Icon

This area displays two icons: the actual icon of a program item selected in the Program Items list box, and a new icon which you created in MegaPaint and which will replace the original one.

The replacement will take place as soon as you close the dialogue by pressing its OK button.

Take great care with this option - once you have replaced an icon it is very difficult to change it back.


Angle ...

is any number between 0 and 360. This number sets how much the currently selected area will be rotated right and is always measured in degrees. You can also type a negative number, for example -45, and rotate the region 45 degrees to the left, which is the same as 315 degrees to the right.


Angle for Slanting ...

is any number between -45 and 45, inclusive. (Bigger angles are always reduced to either 45 or -45.) This number sets how much the currently selected region should be slanted to the right (for positive numbers) or left (for negative numbers). In MegaPaint this angle is always measured in degrees.


Open Contents ...

is a check box which chooses the way MegaPaint acts when you decide to open an image, a bitmap, an icon or a series of icons with Open Bitmap... or Open.... If the Open Contents check box is checked (which is the default in the Open Bitmap dialogue) and you open a graphic (image, bitmap, icon, ... ) with more than one frame, then the Contents window opens first. From there you can go further into the image. If the graphic has only one frame, it appears in the Zoom Area automatically.


Name ...

displays the name of the selected image.


Images ...

is a list box displaying the first frames of all images saved in the selected directory (to start with it is SuperLogo IMAGE subdirectory). The images are shown with the names of their files, or their nicknames - if they were given one while being saved.


Preview

If you check the Preview option, all frames of the currently selected image are displayed here.


Nickname ...

is an alternative name containing up to 8 characters (in any national character set) which can be used to replace the proper file name. However, it is not possible to save a file with a nickname without giving a file name as well.

If an image saved in a file has a nickname and you open the Choose an Image dialogue with Open..., the file is displayed with the nickname as its title.


Title Bar...

contains three standard Windows buttons for opening the  complete control menu, for minimising, maximising and restoring. The Title Bar also contains the MegaPaint application name plus the name of an LGW file, if you have already specified a file.


IMAGE Directory...

is a subdirectory of the SuperLogo home directory. All LGW files are usually stored in the IMAGE directory.


Image Hot Spot ...

is a point [X Y] set for each frame of an image. This point is recognised by all Super Logo image commands and operations as the reference point of the frame. For example, if an image is given to a turtle as its shape, the hot spot of the image (of the frame currently used) is used as the turtle's actual position.

Note that:

each frame of an image has its own hot spot, see SuperLogo primitive operation HOTSPOT,

the upper left corner of the frame is referred to as point [1 1]. The X co-ordinate increases to the right, the Y co-ordinate increases downwards,

the hot spot does not have to be located inside the frame. If the size of a frame is, for example [50 35], it may be [110 20] or [-25 -10] or [60 -10]. Both numbers must be between -255 and 255, inclusive.


Point...

is a SuperLogo list in the form [X Y], where X and Y are numbers.


BMP File ...

is any file containing a standard Windows bitmap. Its extension is usually .BMP. The file includes its own palette and size, that is, width and height.

Colour Number ...

in the MegaPaint Colour Chooser is a list [R G B] of three integers between 0 and 255, inclusive, describing a colour from the extended palette. The three numbers show how much R - red, G - green and B - blue colour is present in the final mixture. The way in which [R G B] colours are displayed on the screen depends on your graphics card and Windows' settings. Whenever Windows is not able to display a colour as a solid colour, it uses a pattern of dots of different colours instead. This is called a non solid colour.


Palette of 16 Basic Colours ...

This is the palette of 16 basic solid colours. To choose any of them, click it with the mouse or select it by pressing Up, Right, Left and Down arrows on the keyboard to move the selection frame.


Specifying RGB Colour ...

To specify a colour as a list [R G B] of three integers, you can use these three horizontal scroll bars.


Colour Preview ...

This box makes it possible to see what the selected colour looks like. However, it will depend on the display and the graphics card driver in your computer

Replace Zoom / Preview Area ...;   F8

If both Zoom Area and Preview Area are displayed and you press the F8 key, the Zoom Area will be replaced by the contents of the Preview Area.

Pressing F8 again will restore the MegaPaint Workplace so that both areas are displayed.


Keep Transparent

If this option is on and you drag a selected area within the frame, its transparent parts will remain transparent. That is, when the selected region is placed above another part of the frame, no pixel below the transparent parts of the region will change colour.

If this option is off (which is the default setting), the dragged selected region will completely cover all pixels below itself.


Grid Size:

In the small edit box here you set the size of a grid used in the Zoom Area. It must be an integer between 4 and 16, inclusive. The default setting is 8.


Save Settings on Exit

If this option is on, all options from the Editor Options dialogue box are saved into the MEGAPAINT.INI file whenever you close MegaPaint. The most recently used path (LastDir) and background colour of the Frame Animation Window are also included in the file. The default setting for this option is off.


Append Bitmap

If this option is on and you select the Open Bitmap dialogue (to load any BMP, LGW or ICO file), the contents of the MegaPaint memory is kept and the newly loaded frames are added at the end of the frames in memory. However, the overall number of frames cannot exceed 250.

If the option is off (which is the default), all frames in MegaPaint's memory are erased first and replaced by the newly loaded frames.


Palette

Here you see 256 colour boxes (some of them possibly empty) organised in 16 rows with 16 colours each. The actual contents of the Palette Window depends on the colour mode you are working in.

In 16 colours mode: 16 basic colours are displayed here plus all the colours you defined with the Colour Chooser or loaded with Open... in this menu. To define a colour you have to hold the Ctrl key down and click any colour box (except boxes in the first row).

In 256 colours mode: the image palette is displayed here (all the colours used in any of its frames, and there may be more colours defined with the Colour Chooser or loaded through Append... in this menu).

In TrueColour mode: 16 basic colours are displayed here plus all the colours you defined with the Colour Chooser or loaded with Open... in this menu or copied  from the Zoom Area by clicking it with the Ctrl key + any mouse button.

If you click any (non empty) colour with the left mouse button, it becomes the foreground colour. If you click any (non empty) colour with the right mouse button, it becomes the background colour.


Palette Window Status Line

When the mouse is moved along the pixels of the Zoom Area, the RGB number of the colour pointed at is displayed here.

If you click this status line with the right mouse button, the Palette Menu is displayed. After choosing some of the commands in this menu, two buttons are displayed.


Reset

Removes all colours - except the 16 basic colours - from the Palette Window.

If you are working in 256 colour mode, all the colours of all the frames in the image in the memory will be reduced to the 16 basic colours. Note that this change cannot be undone by the Undo command!


Delete ...

Switches MegaPaint to a special mode in which you can mark colours to be deleted from the Palette Window. This mode is closed when you click the OK button in the Palette Window status line - the colours are then deleted from the window.

If you are working in 256 colour mode, the marked colours are also deleted  from all frames of the image in the memory. They replaced with the closest colour found in the rest of colours. Note that this change cannot be undone by the Undo command!


Minimise

Can only be used in 256 colour mode. All colours in the Palette Window which are not used in any of the image's frames are removed from the Palette Window. Note that this change cannot be undone by the Undo command!


Reduce ...

Can only be used in 256 colour mode. When selected, the Reduce Palette dialogue is displayed. Here you set the Colour Tolerance (the default is 10) which defines a level of difference between colours to be considered nearly the same. When you click the OK button, MegaPaint will mark all colours which it considers to be close according to the set Colour Tolerance. The list of marked colours can then be modified manually. When you click the OK button in the Palette Window status line, all close colours will be replaced by the most common colour in the group. The change will affect all frames in the image. Note that this change cannot be undone by the Undo command!


Brightness Sort

Rearranges the colours in the Palette Window (except the colours in the first line) so that they are sorted in order of brightness.


RGB Sort

Rearranges the colours in the Palette Window (except those in the first line) into 16 groups of colours close to the 16 basic colours. Within each group they are sorted in order of brightness.


Open ...

The Open Palette dialogue is displayed on the screen. Here you choose any *.PAL file (any Logo palette file) to be opened. When you click the OK button, the palette in the Palette Window is replaced by the palette loaded from the specified file. However, the palettes first row will still contain the same 16 basic colours.

Note that in 256 colour mode, all colours in all frames of the current image are immediately replaced  by the colours of the new palette. This change cannot be undone by the Undo command!


Save As ...

The Save Palette As dialogue is displayed on the screen. Here you name the Logo palette file *.PAL in which you want to save the palette displayed in the Palette Window.


Append ...

The Append Palette dialogue is displayed in the screen. Here you choose any *.PAL file (Logo palette file) to be added to the current contents of the Palette Window. When you click OK, the palette in the Palette Window is extended by the palette loaded from this file - up to 256 colours, the total number of colours in the Palette Window. However, the palette's first row will still contain the same 16 basic colours.
