Some methods are modified a little bit, see lib/excel.iced. You can view documentation in JExcelApi's javadoc. So most APIs of JExcelApi are left unchanged. If I try a jxl file converted via 'cjxl -j', decode_ errors out quite wildly, while jxlinfo gives reasonable output: jpeg-xl/lib/jxl/:416: Skipping 1018-bit extension(s) jpeg-xl/lib/jxl/dec_ans.cc:237: JXL_FAILURE: Alphabet size is too long: 158 jpeg-xl/lib/jxl/dec_ans.cc:332: JXL_FAILURE: Histo DecodeANSCodes jpeg-xl/lib/jxl/coeff_:262: JXL_RETURN_IF_ERROR code=1: DecodeHistograms(br, kPermutationContexts, &code, &context_map) jpeg-xl/lib/jxl/toc.cc:51: JXL_RETURN_IF_ERROR code=1: DecodePermutation( 0, toc_entries, permutation. node-excel-api is a simple wrapper arround the mature JExcelApi project. JXL API supports Excel documents with versions Excel 95, 97, 2000, XP, and 2003.

If I try to decode a jxl file converted from jpeg, I get this output from both examples/decode_ and jxlinfo.c: jpeg-xl/lib/jxl/field_encodings.h:124: JXL_FAILURE: Invalid value 20 for ExtraChannel jpeg-xl/lib/jxl/field_encodings.h:124: JXL_FAILURE: Invalid value 20 for ExtraChannel jpeg-xl/lib/jxl/:705: JXL_RETURN_IF_ERROR code=1: visitor.Visit(fields, PrintVisitors() ? '- Read ' : '') Decoder error Error while decoding the jxl file Example See also References External links Microsoft Excel support.

Unfortunately, I couldn't get it to work at all, and if I try the example programs, they fail in the same way as my own code, so it seems the example code is wrong (as djxl works): Example of JExcel Click Here Labels: Difference between Apache POI and JXL jar. I'm trying to add (preliminary) jpeg-xl decoding support to my image viewer.
