PgSetTextTransPat(), PgSetTextTransPatCx()

Set the draw transparency for text and bitmaps

Synopsis:

void PgSetTextTransPat( PgPattern_t pat );

void PgSetTextTransPatCx( PhGC_t *gc,
                          PgPattern_t pat );

Library:

ph

Description:

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().

Classification:
