Description
Sets the source pattern within cr to source. This pattern
will then be used for any subsequent drawing operation until a new
source pattern is set.Usage
cairoSetSource(cr, source)
Details
Note: The pattern's transformation matrix will be locked to the
user space in effect at the time of cairoSetSource. This means
that further modifications of the current transformation matrix
will not affect the source pattern. See cairoPatternSetMatrix.
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)).
