Function
Gimppaintbrush_default
Declaration [src]
gboolean
gimp_paintbrush_default (
GimpDrawable* drawable,
gsize num_strokes,
const gdouble* strokes
)
Description [src]
Paint in the current brush. The fade out parameter and pull colors from a gradient parameter are set from the paintbrush options dialog. If this dialog has not been activated then the dialog defaults will be used.
This tool is similar to the standard paintbrush. It draws linearly interpolated lines through the specified stroke coordinates. It operates on the specified drawable in the foreground color with the active brush. The ‘fade-out’ parameter is measured in pixels and allows the brush stroke to linearly fall off (value obtained from the option dialog). The pressure is set to the maximum at the beginning of the stroke. As the distance of the stroke nears the fade-out value, the pressure will approach zero. The gradient-length (value obtained from the option dialog) is the distance to spread the gradient over. It is measured in pixels. If the gradient-length is 0, no gradient is used.
Parameters
drawable-
Type:
GimpDrawableThe affected drawable.
The data is owned by the caller of the function. num_strokes-
Type:
gsizeNumber of stroke control points (count each coordinate as 2 points).
strokes-
Type: An array of
doubleArray of stroke coordinates: { s1.x, s1.y, s2.x, s2.y, …, sn.x, sn.y }.
The length of the array is specified in the num_strokesargument.The data is owned by the caller of the function.
