Luratech JPEG2000 decoder seems having problems with some of our test files. I confirmed symptoms with trunk r11365 + luratech lwf_jp2 r10. - tests/pdf/j2kp4-file2-ycc-8bpc.pdf Wrong color. - tests/pdf/j2kp4-file3-ycc-8bpc.pdf Wrong color and different resolution in color channel? - tests/pdf/j2kp4-file6-gray-12bpc.pdf Using lower 8 bits? - tests/pdf/j2kp4-file7-icc-3ch-12bpc.pdf Using wrong bits? - tests/pdf/j2kp4-file9-palette.pdf Infinite loop. - tests_private/comparefiles/Bug690174.pdf Slanted gray image on Mac, slanted image plus black bars on Linux. Those could be luratech library problem or our glue routine problem. I may divide this bug into several later.
Hello voipas@gmail.com, maybe you accidentally changed this bug? It is not a pdfwrite issue and should not be have been reassigned.

I may > divide this bug into several later. From Luratech: All the problems mentioned in the bug are issues related to processes after decompression: color conversion, scaling of bit depth etc... We used the conformance test suite to ensure the correctness of our decoder since the first versions of the SDK. Our JP2 decoder decompresses the JP2 images correctly. You should make sure that the color space, ICC profiles, palettes, chroma subsampling and bit depth are respected and handled correctly in the Ghostscript code.
The following files are also incorrectly rendered by the Luratech decoder: tests_private/pdf/PDF_1.7_FTS/fts_17_1700.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1701.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1702.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1703.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1704.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1705.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1714.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1715.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1716.pdf tests_private/pdf/PDF_1.7_FTS/fts_17_1718.pdf tests_private/pdf/PDF_1.7_FTS/fts_18_1804.pdf tests_private/pdf/PDF_1.7_FTS/fts_18_1805.pdf tests_private/pdf/PDF_1.7_FTS/fts_18_1812.pdf tests_private/pdf/PDF_1.7_FTS/fts_19_1900.pdf tests_private/pdf/PDF_1.7_FTS/fts_19_1906.pdf tests_private/pdf/PDF_1.7_FTS/fts_25_2502.pdf tests_private/pdf/PDF_1.7_FTS/fts_25_2504.pdf tests_private/pdf/PDF_1.7_FTS/fts_25_2505.pdf tests_private/pdf/PDF_1.7_FTS/fts_25_2508.pdf tests_private/pdf/PDF_1.7_FTS/fts_25_2509.pdf tests_private/pdf/PDF_1.7_FTS/fts_25_2512.pdf tests_private/pdf/PDF_1.7_FTS/fts_27_2706a.pdf tests_private/pdf/PDF_1.7_FTS/fts_27_2706b.pdf tests_private/pdf/PDF_1.7_FTS/fts_27_2706c.pdf tests_private/pdf/PDF_1.7_FTS/fts_27_2706d.pdf
Hello Lars can you check which of these problems are still open after the work you and Alex did with the Luratech decoder?
I've reviewed all differences between Luratech and Jasper in our test suite. Luratech renders everything correctly. Jasper doesn't recognize an eYCC color space in j2kp4-file2-eycc-8bpc.pdf
