PNMBrush

class PNMBrush

Bases: ReferenceCount

This class is used to control the shape and color of the drawing operations performed by a PNMPainter object.

Normally, you don’t create a PNMBrush directly; instead, use one of the static PNMBrush::make_*() methods provided here.

A PNMBrush is used to draw the border of a polygon or rectangle, as well as for filling its interior. When it is used to draw a border, the brush is “smeared” over the border; when it is used to fill the interior, it is tiled through the interior.

static PointerTo<PNMBrush> make_image(PNMImage const &image, float xc, float yc, BrushEffect effect = BE_blend)

Returns a new brush that paints with the indicated image. xc and yc indicate the pixel in the center of the brush.

The brush makes a copy of the image; it is safe to deallocate or modify the image after making this call.

static PointerTo<PNMBrush> make_pixel(LColorf const &color, BrushEffect effect = BE_blend)

Returns a new brush that paints a single pixel of the indicated color on a border, or paints a solid color in an interior.

static PointerTo<PNMBrush> make_spot(LColorf const &color, float radius, bool fuzzy, BrushEffect effect = BE_blend)

Returns a new brush that paints a spot of the indicated color and radius. If fuzzy is true, the spot is fuzzy; otherwise, it is hard-edged.

static PointerTo<PNMBrush> make_transparent(void)

Returns a new brush that does not paint anything. Can be used as either a pen or a fill brush to make borderless or unfilled shapes, respectively.
