How can I extract the actual 3D picture used by a GDL/GSM Library Part?

[Emaa]

I’m working on an Archicad add-on and need to export any type image used by a GDL/GSM Library Part in its 3D representation, not only embedded images.

Also, I need only the currently active and selected type image. For ex, in above photo if Sabel Palmetto is selected type in my .pln file then my addon should only extract that image.

Some GDL objects use PICTURE, while others may use external images, textures, or other GDL-based image sources.

I’m looking for a supported Archicad C++ API/workflow to extract the actual image used in the 3D representation to a file (PNG/JPEG/TIFF), without using external tools such as LP_XMLConverter.

Thanks.
