I'm trying to use PdfConverter to create thumbnails for pages of PDFs. The rendering performance is proportional to the resolution, but it is still slow at low resolutions. This table compares resolution vs. time for rendering the first page of a relatively complex PDF:
DPI Time 50 0.874 100 0.982 150 1.089 200 1.218 250 1.331 300 1.531
There seems to be a base time of ~0.8 seconds (for this PDF) even if I render to a 10x10 px image. Is there anything I can do to make this faster? I am willing to sacrifice image quality (it's just a thumbnail), but outputting as jpeg with low quality has little impact on performance.
