Hello everyone,
I've recently started using FOP for a project I'm working on and I'm
needing to produce TIFF group 4 files using FOP. I've tried many different
things and I'm just not able to get things working, well not completely
anyway.
Using the following Fop instance[1] I successfully create a multi-page TIFF
file, however creating a PDF instead generates a file size of 18k while the
TIFF at target resolution of 240dpi produces a file size of 4,894k. I've
also noticed that the default TIFFRenderer uses PACKBITS compression and
I've yet been unable to change this. I've tried to configure the renderer
to use CCITT T.6 compression via configuration file to no avail and I've
noticed that the compression doesnt appear to be settable in
TIFFRenderer[3]? Any and all help in getting a more workable TIFF file size
would be MUCH appreciated!
[1] Fop fop = fopFactory.newFop(
MimeConstants.MIME_TIFF, foUserAgent, out);
[2]
<renderer mime="image/tiff">
<transparent-page-background>true</transparent-page-background>
<compression>CCITT T.6</compression>
</renderer>
[3]
/** Creates TIFF renderer. */
public TIFFRenderer() {
writerParams = new ImageWriterParams();
writerParams.setCompressionMethod(COMPRESSION_PACKBITS);
}
Thanks in advance.
