Palettes

The colour palette displays the colours that the current frame uses - named "main palette" - and the current gradient filling form - named "gradient palette". While the main palette always relates to the current frame, the gradient settings are global and don't change, when a different frame is selected. The next two sections describe the two palettes.

The main palette is either the picture's global palette or a local one, that is only used by a subset of the picture's frames. The blue title bar reflects the palette's visibility. You can click this bar to open the menu bar's palette menu as a context menu.

Each colour in a palette is represented by a small box filled in the corresponding colour. Such a palette entry can have the following decorations:

	A tiny white box in the upper left corner means the colour is the current foreground colour. It's associated with the left mouse button when drawing. To select the current foreground colour, left-click on a palette entry.
	A tiny black box in the lower right corner means the colour is the current background colour. It's associated with the right (or middle) mouse button when drawing. To select the current background colour, right-click on a palette entry.
	A white rectangle around the box means the colour is the frame's background. This colour shines through transparent pixels, if "Colour" is selected as the transparency representation (see the corresponding menu item). To select the frame's background colour, right-click on a palette entry while pressing the Ctrl-key.
	If the box is completely filled with a pattern of tiny gray tiles the colour is the frame's transparent colour. To select the transparent colour, left-click on a palette entry while pressing the Ctrl-key.
	A colour that's not fully opaque is represented by two triangles. The upper left triangle is the transparent pattern, the lower triangle shows the colour itself.

Edit a colour To edit a colour's RGB and alpha values double-click a palette entry. This opens the colour editor dialog which - hopefully - is self-explanatory.

The Gradient Palette

"Gradient fill" means to smoothly change from one colour to another. The gradient palette let's you choose these two colours and set the direction of the colour change.

The two boxes to the right and left of the gradient palette represent the two colours that define the gradient fill. Double-click them to modify their RGB and alpha values. Select one of the boxes between the two gradient colours to specify the direction of the gradient fill. From left to right and row by row these can be the following: Top to bottom Left to right Upper left corner to lower right corner Lower left corner to upper right corner Top to middle Left to middle Upper left corner to middle Lower left corner to middle The "Cycle" check box affects the fill patterns in the second row. After reaching the middle, the colour change is repeated back to the starting colour. The "Invert" check box applies to all patterns and swaps the two selected colours with each other.
