Drawing Modes and Opacity

Drawing modes

(The terms color, value and saturation refer to the HSV color model, which is sketched at the end of the section mapping colors and flood fill.)

Opacity

If you set opacity to a value less then 100 %, Babygimp proceeds as follows: First the RGB value to be drawn pixel is determined according to the current drawing mode. Then Babygimp draws a weighted mean of this RGB and the RGB of the image pixel.

When drawing on the background, opacity is ignored.

Example:

Here you see the effect of drawing a filled rectangle in different drawing mode

[Example 0] Original

[Example 1] Normal

[Example 2] Erase

[Example 3] Background

[Example 4] Foreground

[Example 5] Color

[Example 6] Foreground (low opacity)
