Set the draw transparency for text and bitmaps
void PgSetTextTransPat( PgPattern_t pat ); void PgSetTextTransPatCx( PhGC_t *gc, PgPattern_t pat );
ph
These functions set a masking pattern and applies it to text and bitmaps. You should use it in combination with PgSetTextColor*() or PgSetTextDither*().
These functions use the same patterns as PgSetFillDither*(). To disable transparency and draw normally, specify the Pg_PAT_DEFAULT pattern.
Because of speed considerations, some graphics drivers don't draw strokes with a transparency mask and, as a result, ignore the stroke transparency pattern. |
PgSetTextTransPat() works on the current graphics context, while you can specify the graphics context gc for PgSetTextTransPatCx().
