Get trimmed and twisted picture frame information

I need to get information about pixels in a picture frame inserted in Rhino.
I already know how to do this on an external image. (System.Drawing.Bitmap.FromFile)
There is some method in Rhino.Geometry to do this within Rhino with a picture frame?
This picture frame will be twisted and trimmed with Shrink.

Moved to Scripting category so your message will be seen.

Hi @cristiano.pasini,

There should be a new RhinoObject.IsPictureFrame property available in the Rhino 7 SR9 release candidate.

import Rhino
import scriptcontext

def test_picture_frame():
    filter = Rhino.DocObjects.ObjectType.Surface
    rc, objref = Rhino.Input.RhinoGet.GetOneObject("Select surface", False, filter)
    if rc != Rhino.Commands.Result.Success: retirm
    rh_obj = objref.Object()
    if not rh_obj: return
    rc = rh_obj.IsPictureFrame
    print("Picture frame = {0}".format(rc))

if __name__=="__main__":

Once you’ve determined an object is a picture frame, it’s just a matter if looking at it’s render material.
