There's partial support for old jpeg and none for new jpeg. Partial support means that the image must be in a single band and must work without decompression in PDF.

TiffImage.getNumberOfPages(ra) returns the right number of pictures. TiffImage.getTiffImage(ra, i) don't return a valid jpeg document. after saving the multipage tiff using different formats, i determined the following: - multipage tiff with no compression: works well - multipage tiff with lzw compression: works well - multipage tiff with packbits compression: works well - multipage tiff with zip compression: works well - multipage tiff with jpeg compression: dont works (skipped by the getTiffImage() method) while calling TiffImage.getTiffImage() for the first image using the original multipage tiff file with old jpeg, following tags where found: TIFFTAG_BITSPERSAMPLE =8 TIFFTAG_COMPRESSION =6 TIFFTAG_IMAGELENGTH =480 TIFFTAG_IMAGEWIDTH =640 TIFFTAG_JPEGACTABLES =793 TIFFTAG_JPEGDCTABLES =768 TIFFTAG_JPEGIFBYTECOUNT =411 TIFFTAG_JPEGIFOFFSET =520 TIFFTAG_JPEGPROC =1 TIFFTAG_JPEGQTABLES =634 TIFFTAG_ORIENTATION =1 TIFFTAG_PHOTOMETRIC =2 TIFFTAG_PLANARCONFIG =1 TIFFTAG_RESOLUTIONUNIT =2 TIFFTAG_ROWSPERSTRIP =480 TIFFTAG_SAMPLESPERPIXEL =3 TIFFTAG_STRIPBYTECOUNTS =54007 TIFFTAG_STRIPOFFSETS =931 TIFFTAG_SUBFILETYPE =0 The total length of the file is: 227507 bytes The indexes of the jpeg start points FF+D8 (manually searched): 520 55450 107352 150252 196456 After saving the segments to files with the jpg extension, i find out, that those files where valid. It seems that the multipage tiff whith old jpeg format is constructed as follows: from index 0 to 519: header from index 520 to 55449: first jpeg file from index 55450 to 107351: second jpeg file from index 107352 to 150251: third jpeg file from index 150252 to 196455: fourth jpeg file from index 196456 to 227506: fourth jpeg file how can i make itext work with multipage tiff containing old jpeg (and perhaps jpeg) files? thank you for the support!
