Gary Lucas commented on IMAGING-194: ------------------------------------ Does anyone have some manageable-sized, public domain files that we can use to develop/test this capability? > Tiff with JPEG,Zip compression fails to decompress > -------------------------------------------------- > > Key: IMAGING-194 > URL: https://issues.apache.org/jira/browse/IMAGING-194 > Project: Commons Imaging > Issue Type: Improvement > Components: Format: TIFF > Affects Versions: 1.0-alpha1 > Reporter: Satya Deep Maheshwari > Priority: Major > > Tiff with JPEG, Zip compression fails to decompress with the below exception: > {code} > org.apache.commons.imaging.ImageReadException: Tiff: unknown/unsupported > compression: 7 > at > org.apache.commons.imaging.formats.tiff.datareaders.DataReader.decompress(DataReader.java:215) > at > org.apache.commons.imaging.formats.tiff.datareaders.DataReaderStrips.readImageData(DataReaderStrips.java:210) > at > org.apache.commons.imaging.formats.tiff.TiffImageParser.getBufferedImage(TiffImageParser.java:650) > at > org.apache.commons.imaging.formats.tiff.TiffDirectory.getTiffImage(TiffDirectory.java:157) > at > org.apache.commons.imaging.formats.tiff.TiffImageParser.getBufferedImage(TiffImageParser.java:463) > at > org.apache.commons.imaging.Imaging.getBufferedImage(Imaging.java:1407) > at > org.apache.commons.imaging.Imaging.getBufferedImage(Imaging.java:1370) > {code} > From the > [documentation|https://commons.apache.org/proper/commons-imaging/formatsupport.html] > , it seems this compression format is not supported. Excerpt from the > document below: > {quote} > Supported through version 6.0. TIFFs is a open-ended container format, so > it's not possible to support every possibly variation. Supports Bi-Level, > Palette/Indexed, RGB, CMYK, YCbCr, CIELab and LOGLUV images. Supports reading > and writing LZW, CCITT Modified Huffman/Group 3/Group 4, and Packbits/RLE > compression. Notably missing other forms of compression though, including > JPEG. Supports reading Tiled images. > {quote} > This ticket is logged to add JPEG/Zip compression format support. -- This message was sent by Atlassian Jira (v8.3.4#803005)
