Is there a good way to extract images from the model?

We used ProRasterFileWrite to extract the model shown in the window as a JPEG.
However, images extracted using ProRasterFileWrite are extracted with the background of the window both up and down.

We want to extract images like thumbnails that appear in CREO VIEW.

Does anyone know how to extract images from a model in a different way without using ProRasterFileWrite?
We will use the extracted image to create a BOM Excel file.

thank
