When sliding down the button after choosing the PHOTOS menu then you'll arrive to LUDA.BMP
after LUDA you'll see the color bar picture, but the bottom line of LUDA.
But if you're currious just slide up the button to show again LUDA and then you'll see that on the top of screen you'll see the color bar picture on the first line.
If you slide up again then a picture of the desert then you'll be able to see the bottom line of LUDA.
this LUDA bottom line still displayed if you still slide up to see previous picture
The other good question is: why the most right column of pixe is not used to display the pictures?
LUDA is 128x128 pixel may be this an explanation?
I fist thought that that was because BMP files are coded starting from bottom to top, but it seem that BMY files are also coded this way. By the way BMP picture seem to be displayed slower than BMY one. It's certainly because the BMP is 24bits per pixel and the display cannot handle this color depth.
On more question: what is the display size of the display? I've read 132x132 on Jelu.se, and 131x131 on this forum.
What is the right answer?
