Set line thickness
int PgSetStrokeWidth( int width ); long PgSetStrokeFWidth( long width ); int PgSetStrokeWidthCx( PhGC_t *gc, int width ); long PgSetStrokeFWidthCx( PhGC_t *gc, long width );
ph
These functions set the thickness of lines.
If you call PgSetStrokeWidth*(), the width argument takes an integer that indicates the width of the line in pixels. But if you call PgSetStrokeFWidth*(), the width argument takes a pixel width multiplied by 65,536 (0x10000). For example, specifying a value of 0x80000 will set the line width to 8 pixels.
The minimum line width for PgSetStrokeFWidth*() is one pixel. |
PgSetStrokeWidth() and PgSetStrokeFWidth() work on the current graphics context, while you can specify the graphics context gc for PgSetStrokeWidthCx() and PgSetStrokeFWidthCx().

We don't recommend using a line width greater than one pixel. Some graphics drivers might give unexpected results.
