MGL_getPenBitmapPattern
Returns the currently active bitmap pattern index, and pattern data.
Declaration
int MGLAPI MGL_getPenBitmapPattern(
int index,
pattern_t *pat)
Prototype In
mgraph.h
Parameters
index |
Index of the bitmap pattern slot to read from |
pat |
Place to store the bitmap pattern |
Return Value
Currently active bitmap pattern index.
Description
This function returns a copy of the specified bitmap pattern used when rendering patterned primitives in the MGL_BITMAP_TRANSPARENT and MGL_BITMAP_OPQAUE pen styles. It also returns the currently active bitmap pattern index, since the MGL supports 8 patterns cached internally in the driver.
Note: You can pass a value of NULL in the pat parameter, and the pattern data will not be copied. Ie: MGL_getPenBitmapPattern(0,NULL) returns just the currently active bitmap pattern index.
