Need Intermediate Outputs During JPEG Decode

Post by skitchjr »

Hi There,

I'm doing verification on a JPEG RTL core, and successfully using the 'convert' tool to create readable YCC output:
convert input.jpg -colorspace YCbCr txt:- > textfile.txt
(Done with your help: https://www.imagemagick.org/discourse-s ... =1&t=32075 )

My current issue is debugging the middle stages of the conversion. Is there any way to print out the outputs of the Huffman/Dequantizer/IDCT? We're running into mismatches; but it's rather difficult figuring out where things go awry.

Thanks!
