Thank you for your reply. Your IJG 8.0b IPP sample is exactly what we need.
We use IJG together with LibTIFF, both in source code form, in order to providedecoding and encoding forTIFF_JPEG. The IJG we are currently linking is version 8a, unmodified. The LibTIFF we are linking is version 3.9.5, with modifications and bugfixes. These bugfixes affect the header validation at the beginning of the TIFF_JPEG stream, but do not affect the core computation of JPEG decoding.
Along a similar line, we are also looking for a tighter and more complete integration of IPP with LibTIFF. The TIFF decoder that was included with IPP sample only supports uncompressed mode, which is not relevant to us at all. The major compression modes we require are: TIFF_JPEG, TIFF_ZIP, TIFF_LZW, TIFF_GROUP4.
