Regarding the image rendering engine - indeed. I made a brief article detailing how you can make the images look better - Optimising documents for a 6" eink display
In brief, I've noticed you obtain far better results processing the documents in advance on your computer. (i.e. downscale & reduce colours using your PC prior to putting on the device).
I find that IrfanView does a fine job of preparing documents in advance. Turn off dithering and reduce the colors to gray scale and then to reduced values. I disagree a little with reducing it to 2 bits. I reduce to 4 bits in the hopes that the future versions will support higher levels of gray scale and I don't want to have to regenerate all of my documents. Letting the machine do this minor adjustment usually works well. By the way, there is no way to reduce below 8 levels (265 gray scale) on a Jpeg anyway.
