With the previous instruction, we were able to successfully load a thumbnail of an OLE image on the VISIO. However, the default outline size is too small and not readable when compare to the image size after opening it with the actual excel and saving into VISIO. I have attached two compared images side by side for your understanding.

Question here is how can I set correct width and height of an OLE preview so it can be better readable with more outlined in size by default without even opening and closing the OLE excel?
