Hello,

II try to use UIC::JpegExEncoder to compress a Mono 640x480  8bit image.Encodiong seems OK no error.

But the result image is blank. Quality is 75.   Do you have any idea?

Thanks

The Bmp and wdp file attached(Rename Camera 1-1.wdp.jpg to Camera 1-1.wdp). And followed is my code:

Hello, The attached input bmp file looks corrupted, and cannot open from here. Could you have a check? Thanks, Chao

Hi, I found problem:amount of tiles per rows and columns can't be 0. So the fix is: iTilesUniform[0] = 1; iTilesUniform[1] = 1; Thanks.
