Tilman Hausherr commented on PDFBOX-1734:
-----------------------------------------
Until now I ran only a few tests. I will run all the tests (i.e. lots of files)
tonight or tomorrow night and come back here and attach the proposed module.
Indeed, the version 0.97 doesn't do the job and I almost gave up. I used the
snapshot version 1.0 and I'm impressed, because the first code that compiled
did do what I wanted.
> ImageIoUtil.WriteImage doesn't work with tiff images

> ImageIoUtil.WriteImage brings an I/O error exception when trying to write a
> tiff file. Debugging shows that the cause is "Bits per sample must be 1 for
> RLE compression!". This means that the compression used (the first one of the
> following list, returned by writerParams.getCompressionTypes() ) is only
> allowed for bitonal images.
> CCITT RLE
> CCITT T.4
> CCITT T.6
> LZW
> JPEG
> ZLib
> PackBits
> Deflate
> EXIF JPEG
> After correcting this, the next problem was that tiff images didn't have the
> proper resolutions. I added that too. Yes it uses the com.sun.* classes;
> however there is no other way. Even apache xmlgraphics uses them, although in
> a very different way than I do
> https://svn.apache.org/repos/asf/xmlgraphics/commons/tags/commons-1_3_1/src/java/org/apache/xmlgraphics/image/writer/imageio/ImageIOTIFFImageWriter.java
> writeImage() has a parameter "int imageType" which is never used. Why?
