Name
cpattern:BeginPatch -- begin patch
Synopsis
cpattern:BeginPatch()
Function
Begin a patch in a mesh pattern.

After calling this function, the patch shape should be defined with cpattern:MoveTo(), cpattern:LineTo() and cpattern:CurveTo().

After defining the patch, cpattern:EndPatch() must be called before using the pattern as a source or mask.

Note: If the pattern is not a mesh pattern then it will be put into an error status with a status of #CAIRO_STATUS_PATTERN_TYPE_MISMATCH. If the pattern already has a current patch, it will be put into an error status with a status of #CAIRO_STATUS_INVALID_MESH_CONSTRUCTION.
