PSBrush, PSColor, PSFont, PSPattern - graphics state objects with added PostScript information

#include <Unidraw/Graphic/pspaint.h>

PSBrush, PSColor, PSFont, and PSPattern are subclasses of Brush, Color, Font, and Pattern, respectively, that store added information needed to generate idraw-compatible PostScript. Unidraw's structured graphics objects use these subclasses exclusively.

Create an undefined PSBrush (the parameterless constructor) or one having the specified line pattern and width. Structured graphics having an undefined brush will not render their stroked portions.
Return constructor-specified brush parameters.
Return true if this is an undefined brush.
Return values required to characterize the brush in PostScript. The equivalent PostScript dash pattern is computed from the brush's line pattern.

Compute the equivalent PostScript dash pattern from the line pattern specified in the constructor.

)

Create a PSColor, supplying color intensity information and a name to associate with the intensities. The name is used solely to generate idraw-compatible PostScript.

)

Construct a PSFont, supplying the window-system-specified font name and the corresponding PostScript font name and its size.
Return constructor-supplied parameters. GetPrintFontAndSize returns the concatenation of the PostScript font name and its size, with a space interposed for legibility.
Return an integer version of the PostScript font's size (as supplied to the constructor).

Create an undefined PSPattern (the parameterless constructor), or one having specific dither and graylevel values, or one that replicates a pattern defined by the given array. Structured graphics having an undefined pattern will not render their filled portions.
Return true if this is an undefined pattern.
Return the graylevel that the pattern approximates, if one was specified in the constructor.
Return the array that defines the replicated pattern and its size, if the pattern was constructed with one.
