| Summary | 0000049: handling of color faxes with DNL flag (height defined at end of image) | |||||||||||
| Description |
It seems like if some rare fax machines send color faxes as CFF but with the DNL marker (i.e. height of image is defined as 0 in the header and added with DNL marker at the end). No known tool handles this currently (neither jpeg2ps nor gimp). It would be good to get this feature into the main tools. For details see the JPEG spec. The technical details: Image width and height are defined in the SOF0 marker in the JPEG header, i.e. FF C0 <word: length> <byte: bits_per_component> <word: image height> <word: image width> (see also readjpeg.c/AnalyzeJPEG/case M_SOF0) For the case meant here, height is specified as 0 which causes most tools to fail. At the end, you'll find the DNL marker: FF DC <word: length> <word: image height> |
