| void IE_ImpGraphic_GdkPixbuf::_createPNGFromPixbuf | ( | GdkPixbuf * | pixbuf | ) | [private] |
This method fills the m_pPNG byte buffer with a PNG representation of of the supplied gdk-pixbuf. This can be saved in the PT as a data-item and recreated. ppBB is a pointer to a pointer of a byte buffer. It's the callers job to delete it.
