CairoContext::copyPath -- cairo_copy_path — Creates a copy of the current path
Opis
Styl obiektowy (method):
Styl proceduralny:
Creates a copy of the current path and returns it to the user as a CairoPath. See CairoPath for hints on how to iterate over the returned data structure.
This function will always return a valid CairoPath object, but the result will have no data, if either of the following conditions hold:
- 1. If there is insufficient memory to copy the path. In this case CairoPath->status will be set to CAIRO_STATUS_NO_MEMORY.
- 2. If
contextis already in an error state. In this case CairoPath->status will contain the same status that would be returned by cairo_status().
Parametry
-
context -
A valid CairoContext object created with CairoContext::__construct() or cairo_create()
Zwracane wartości
A copy of the current CairoPath in the context
