Draw a rounded rectangle
int PgDrawRoundRect( PhRect_t const *rect, PhPoint_t const *radii, unsigned flags ); int PgDrawRoundRectCx( void *dc, PhRect_t const *rect, PhPoint_t const *radii, unsigned flags );
ph
These functions build a command in the draw buffer to draw a rounded rectangle. The rect argument is a pointer to a PhRect_t structure that defines the extent of the rectangle. The radii is a pointer to a PhPoint_t structure that defines the roundness of the corners, in pixels.
The flags argument must be one of the following:
Since the value of radii is truncated to the size of the rectangle, you should find this function useful for drawing ellipses within a rectangular area (see example below).
PgDrawRoundRect() works on the current draw context, while you can specify the draw context dc for PgDrawRoundRectCx().
The following example:
DrawStrokeRRect() { PhRect_t rect = { 8, 8, 152, 112 }; PhPoint_t radii = { 32, 32 }; PgSetStrokeColor( Pg_WHITE ); PgDrawRoundRect( &rect, &radii, Pg_DRAW_STROKE ); }
will draw:
The following example:
DrawFillRRect() { PhRect_t rect = { 8, 8, 152, 112 }; PhPoint_t radii = { 32, 32 }; PgSetFillColor( Pg_PURPLE ); PgDrawRoundRect( &rect, &radii, Pg_DRAW_FILL ); }
will draw:
The following example:
DrawFillStrokeRRect() { PhRect_t rect = { 8, 8, 152, 112 }; PhPoint_t radii = { 1000, 1000 }; PgSetFillColor( Pg_PURPLE ); PgSetStrokeColor( Pg_WHITE ); PgDrawRoundRect( &rect, &radii, Pg_DRAW_FILL_STROKE ); }
will draw:
