So, another request for some of the guys who have the DR800S in Europe.

Again, I've been playing with the emulator, and some of the behavior of image rendering in ePubs concerns me. Not so much that the iRex seems to lack dithering (although it seems like it'd be fairly straight-foward to at least add a simple one... at least from adding it to my feeds tool)... but rescaling.

So the problem I have is this: I have a CBZ file I convert using either a tool I'm writing, or Calibre. It sets the image to be somewhere in the range of 670x974 pixels, which should fit the screen. The CSS I use is a bit different from Calibre, but works just fine on the 505 and 900, as does Calibre's method.

I take either one and drop it onto the DR800SG emulator though, and the images are forcibly rescaled into a space about 2/3rds the height of the screen. (~770 pixels). Even if the CSS tells it to render at a specific height or width, it ignores it and rescales it down anyways. If I take out one of the images in the ePub, throw it into the images folder and open that, it looks just fine and isn't scaled down at all, so I know it fits the screen correctly.

I was wondering if someone with a real device could reproduce this, or if it might be an emulator-only bug. If it repros on real hardware, it basically kills my desire to pick one up.
