Not sure I understand this request, you cannot make a 2d image from a 3d shape that would be of any reasonable use.
I am able to create a series of holes using a circle and the 3D molding polyline, multiple copy them and add to the library, but material is not an option.
I have attached an example of this for a light.
I could find an image to use to do this, but I want the circles to actually have real holes so light can shine through them. But in this instance I would like to make a series of metal circles to use to "paint" a hemi-sphere. I have made many new materials from images. The figure shows an open curve (left) and a closed curve (right).I am wondering if you can create a new material from polylines. (Optional) End your curve at the point where you started drawing to create a closed shape.
