gf_context_set_penwidth()

Set the pen width

Synopsis:

#include <gf/gf.h>

unsigned gf_context_set_penwidth( gf_context_t context,
                                  unsigned  w );

Arguments:

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.

Library:

gf

Description:

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.

Returns:

The previous pen width.
