user space in effect at the time of cairo.context.Context.setSource. This means that further modifications of the current transformation matrix will not affect the source pattern. See cairo.pattern.Pattern.setMatrix.
The default source pattern is a solid pattern that is opaque black, (that is, it is equivalent to cairo_set_source_rgb(cr, 0.0, 0.0, 0.0)).
Parameters
source | a #cairo_pattern_t to be used as the source for subsequent drawing operations. |
