Set the pen width
#include <gf/gf.h>
unsigned gf_context_set_penwidth( gf_context_t context,
unsigned w );
- context
- The draw context to set the pen width for.
- w
- The width of the line, in pixels. Set to 0 to reset the pen width to the default rendering of thin primitives.
gf
This function replaces the pixel width of lines for draw primitives such as lines and points.
|
- Currently pen width applies only to polylines on hardware that has accelerated thick line support.
- The maximum pen width is determined by the hardware. No drawing occurs if the pen width is set to a value that exceeds the maximum. See the Hardware Capabilities appendix for your hardware target's limitations.
