Detailed Description
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.

Member Function Documentation
◆ get_xc()
|
inline |
Returns the coordinates of the brush's center pixel.
For a one-pixel brush, this will be (0.5, 0.5); for a centered two-pixel brush, this will be (1.0, 1.0); for a centered three-pixel brush, this will be (1.5, 1.5); and so on.
Definition at line 28 of file pnmBrush.I.
◆ get_yc()
|
inline |
Returns the coordinates of the brush's center pixel.
For a one-pixel brush, this will be (0.5, 0.5); for a centered two-pixel brush, this will be (1.0, 1.0); for a centered three-pixel brush, this will be (1.5, 1.5); and so on.
