602 FBreader : a different way of displaying images ? - Page 2

Tulapi, wallcraft
Hardware doesn't matter except the eInk screen itself. To use more that 4 colors it requires several screen updates. So it's at least twice slower.
It's a technology limitation: single screen update can display only 4 different colors.

About speed guys have asked me already. Pro series has a new quicker way to display pages. But without SDK I cannot use it and it's noticeable.
So do you think the speed is not important?

Yes, it'll take a bunch of time to implement that. Because rendering deals with the screenbuffer itself. And format of the buffer directly depends on used mode.

This problem seems to be now solved with the new firmware.
