Tilman Hausherr commented on PDFBOX-1734:
-----------------------------------------
Sadly, I found two arguments against Apache Imaging - for now. One is that the
size is sometimes bigger than with java imageio (see IMAGING-126 that I just
created), the other is that it doesn't support writing JPEGs.
About the Sun code you just found: it looks quite similar to the module names
from the com.sun.* code. We'll have to see whether it does whats needed.
> 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?
