I'm wondering if anyone has ever coded a PDF reader for Classpad 3x0? Would it even possible? Since I've no idea how much calculation power would rendering a PDF require?

I don't know what the advantages to having a PDF reader on the ClassPad are. I think it would be better to have black and white pic viewer with some utility for the PC to convert.

PDF files take up a lot of space and I think such a true PDF reader would be too complex to implement on the ClassPad especially with only a 240x128 resolution screen.

If it was all text with very few images, it'd be a little smaller than a high-ish resolution image? Altho, copying the text isn't an opinion, because it has mathematical expressions, which aren't directly copyable to Classpad. Why do ppl generally use PDF instead of images? :)

Hmm, yeah. But all those image converting progs have been very limited about the size of the pictue. I'd be great to save pdfs/pictures with a decent resolution and have a zoom in/out option.

Have I missed some apps, or is it really true that you can't have a, let's say 1280x1024 picture with zoom and scrolling?

I think what you are suggesting may be possible. There would have to be some utility on the computer to first, tranfser thye image to B&W, then create an addin to display the picture, (one addin to display all would be far too much strain on the calcs stack). The pixels could be stored in a matrix or list and scrolling would change the screen accordingly. I dont think zooming would be possible
