problems in ImageMagick

[nemorino]

I'm testing ipp-samples/image-codecs/ijg.
cjpeg, djpeg in utilites have no problem.
But, some problmes are happen in using ImageMagick with libjpeg.so.ipp

I have tested with convert in ImageMagick/utilities.

$ convert -resize 400x300 test.jpg testout.jpg
convert: Premature end of JPEG file 'test.jpg' @ jpeg.c/EmitMessage/226.

This problem is happen in any jpeg file.
What's wrong?

env : IPP6.1.1.042
gcc 3.4.6

Please pay attention to how IPP is used in libjpeg. It requires custom jdatasrc.c and jdata dst.c file (usually an application part)

Hmm.
I will see the files.
jdatasrc.c and jdata dst.c

Nemorino,

I tried IJG sample with some version of ImageMagic. The jpeg.c file in ImageMagick need to be changed (attached). It may depend on the version of imagemagic. You can search INTEL_IJG to find what was changed to accommodate IPP sample code.

Thanks,
Chao
