Member Function Documentation

void BrushBitmap.border (  Color  color  )

Set wrapping mode to border. When a sample point is out-of-range, the passed color is returned.

Color BrushBitmap.eval (  float  x, float  y )

Evaluate the bitmap at that point. First it divides by scale and subtracts the center. Then it applies the contortion; then it wraps and returns the color sampled at that point. Reimplemented from Brush.

void BrushBitmap.saturate (   )

Set wrapping mode to saturate. When a sample point is out-of-range, the nearest in-range edge is used for the color.

BrushBitmap.this (  Bitmap  bitmap  )

Set the bitmap that will be sampled from. Wrap mode is wrap.

void BrushBitmap.wrap (   )

Set wrapping mode to wrap. When a sample point is out-of-range, it wraps around to the other side of the bitmap.
