The ICC Profile is often not part of the PDF as most software converts to DeviceCMYK or uses current profile set in PDF. Display width and height is calculated by the plugin. That is the size of points on the page the PDF is drawn. If Display width and pixel width are the same, the image is displayed with 72 dpi.

This function uses the parser interface in DynaPDF and needs a Pro license.
