Whenever possible the right mouse button uses an inverse operation like darken if the mode is brighten.
Some paint modes do color calculations. Because there are only 256 colors that can be used the quality of the result may be poor if your palette does not contain proper entries. The more colors of different kind your color table contains the better the results will be.
Some paint modes can be configured using the Settings... menu entry.
PaintPaints with current brush as it is. That means the brush is simply stamped down.
EraseUses the transparent color for painting if there is no alpha plane. If alpha is enabled then the left mouse button reduces the opacity by the given value where the right mouse button draws fully transparent. In detail it works like this:
Project has simple or no transparency
any mouse button= transparent color if layer is transparent or project background color if it is not
Project has alpha transparency left mouse button= decrease alpha by selected opacity
right mouse button= set zero alpha
SelectionInstead of modifying pixels this mode will modify the mask. This way you can apply the drawing mask easily using any drawing tool. The left mouse button includes and the right excludes for masking.
HalftoneUses the currently selected dither pattern for drawing. It will use the selected foreground and background color with the pattern.
BrightnessBrightens image colors with left mouse button and darkens with the right. You can set the strength of brightening in the Settings.
TintTints image colors with brush colors. That means the brightness of each image pixel is taken and the color from the corresponding brush pixel. Both are mixed together and the result is a pixel with the brush pixel color and the image pixel brightness.
Inc/Dec HueTakes the Hue (color model HSV) of the image pixels and rotates it (0..360°). You can set the strength of this mode in the Settings
Inc/Dec SaturationIncrements/decrements the Saturation(color model HSV) of the image pixel colors. You can set the strength and type of this mode in the Settings
InvertSimply inverts the image colors using the RGB-color model. A Red value of f.e. 40 will then be 215 (=255-40). The mode will try to find the best matching inverse color in the palette.
DifferenceUses difference values between image and brush colors for painting (RGB color model).
TranslucentMixes image and brush colors. You can define a proportional weighting for this mode. That means the result color is calculated by x% of the image color and y% of the brush color and x+y=100%. See the paint mode Settings below.
Color CycleUses the colors of the current gradient one after another. If the last gradient color is passed the first one is used again...
GrayReduces the image colors to gray levels.
Rub ThroughWhen drawing with this mode the image that resides in the "Spare Frame" (see descriptions for menu Frame) becomes visible. You "rub through" to the spare frame.
ShadeShifts the image colors which are part of the current gradient. So for each color the next or previous color within the gradient will be used depending on left or right click. This way you can shade objects to emphasize their structure, to create different color effects or to smooth edges.
Multi ShadeWorks the same as Shade but uses mor than a single gradient at a time. It only works for gradients that are set up for multi shade paint mode. Because you might want to have gradients that are not touched by the multi shade you must enable a gradient that may be used. Just go to the gradient editor and activate multi shade paint mode for the gradients that may be used for this paint mode.
Paint single ColorDraws using current foreground color regardless if the brush has more than one color.
ReplaceDraws with the current brush but without transparency. Instead it is stamped down as is.
SmearSmears the colors in the drawing direction. Only use with continuous painting or continuous line modes.
BlendSmears the colors in the drawing direction and applies smoothing. Only use with continuous painting or continuous line modes.
FormulaThis mode can be used to modify pixels using different types of mathematical formulas. See Settings for further information.
High PassIncreases brightness contrasts.
SoftenSoftens color contrasts and makes the image blurry.
Soften moreStronger soften mode.
Light Edges SEEmphasizes edges that are nearly parallel to south, east or south east direction.
Light Edges NWEmphasizes edges that are nearly parallel to west, north or north west direction.
Emboss IPuts dark colored areas into the "background". So the objects look embossed.
Emboss IIPuts light colored areas into the "background".
DitherEnable this option if you want to draw using a dither pattern. See paint mode settings for pattern selection.
SettingsHere you can change values for certain paint modes.
