Pattern - fill patterns for a painter

#include <InterViews/pattern.h>

A pattern defines how to fill areas during graphics operations. The global variables ``solid'' and ``clear'' point to patterns for filling all or none of the pixels in a particular area; ``lightgray'', ``gray'', and ``darkgray'' point to patterns for filling one-eighth, one-half, or seven-eighths of the pixels in an area respectively.

Pattern(int b[patternHeight])

Construct a pattern from the array b. For each element of b, the least significant patternWidth bits are used. If a bit is one, then the foreground color will be used when filling. Otherwise, the background color will be used. The first pattern element defines the topmost row of pixels, and the least significant bit of each element defines the rightmost column.

Pattern(int i)

Construct a pattern by interpreting the least signficant 16 bits of i as a 4x4 bitmap and replicating it to make a full patternWidth by patternHeight array.

Pattern(Bitmap*)

Construct a pattern from the bitmap. If necessary, the bitmap will be tiled or truncated to satisfy window system requirements for fill pattern sizes.
