Andreas Lehmkühler commented on PDFBOX-1734:
--------------------------------------------
I'm thinking about that for quite some time, but IMO we have to wait until
imaging 1.0 will be released as some of the needed features are not available
in the current stable version 0.97.
[~tilman] Did you already run some tests? Maybe I'm wrong and (mostly)
everything already works?
> ImageIoUtil.WriteImage doesn't work with tiff images

> Key: PDFBOX-1734
> URL: https://issues.apache.org/jira/browse/PDFBOX-1734

> Issue Type: Improvement
> Environment: XP, W7

> 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?
