Is there a doc showing the available options to be passed to CSPlatformRenderer. I need to increase the render resolution of image pdfs so I guess it's an option here?
currently "options" are not used by any of the standard interpreter.
What exactly do you mean with "increase the render resolution"? I assume you render to a bitmap and want a larger drawing area? There is an examlke in "RenderDoc" where you can see how to scale up the drawing area by scaling the user space.
Images in the content stream are mapped directly to the drawing area without (well, mostly) any prior up/downscale.
