| cairoSetSource {RGtk2} | R Documentation |
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.
cairoSetSource(cr, source)
|
[Cairo] a cairo context |
|
[CairoPattern] a CairoPattern to be used as the source for
subsequent drawing operations. |
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.
XXX: I'd also like to direct the reader's attention to some (not-yet-written) section on cairo's imaging model. How would I do that if such a section existed? (cworth).
