Damjan Jovanovic commented on IMAGING-126: ------------------------------------------ Guys I've gone further than that: I even have a patch to Imaging which implements LZW decompression using the classes in Compress, and copies those classes into Imaging's JAR using maven-shade-plugin to avoid a run-time dependency. It passed all the tests, and was even somewhat faster than Imaging's LZW in my preliminary benchmarks - can't remember by how much though. It's not committed yet because I wasn't sure if Imaging could/should depend on a SNAPSHOT version of Compress, and there still hasn't been any new releases of Compress since before my LZW changes to it were committed. > TIFF and PNG images should not be bigger than the ones created by java ImageIO > ------------------------------------------------------------------------------ > > Key: IMAGING-126 > URL: https://issues.apache.org/jira/browse/IMAGING-126 > Project: Commons Imaging > Issue Type: Improvement > Components: Format: PNG, Format: TIFF > Affects Versions: 1.0 > Environment: W7 > Reporter: Tilman Hausherr > Priority: Minor > Fix For: Discussion > > Attachments: Imaging_126_patch_1.patch, pdfbox-1870-devicen3-01.png, > pdfbox-1870-devicen3-01.tif, pdfbox-1870-devicen3.pdf-1.png, > pdfbox-1870-devicen3.pdf-1.tif > > > I tried to use Apache Imaging for the PDFBOX project (PDFBOX-1734) because of > problems with setting the tiff resolution in java imageio. > While the code is pretty nice, I found that the generated images are > sometimes much bigger in size than the ones generated by java imageio. > Example: > pdfbox-1870-devicen3-01.png 50 KB (imageio) > pdfbox-1870-devicen3.pdf-1.png 70 KB (imaging) > pdfbox-1870-devicen3-01.tif 401 KB (imageio) > pdfbox-1870-devicen3.pdf-1.tif 1063 KB (imaging) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
