Re: Help needed in converting XML to Tiff
You can use this to instantiate the FOP object: Fop fop = fopFactory.newFop(MimeConstants.MIME_TIFF, userAgent, mtiff); where userAgent is a FOUserAgent instance that you can use to configure your tiff and mtiff is the OutputStream where you want the image to be generated. For further configuration (different image compressions) currently there's a developement on the trunk version of FOP and xmlgraphics-commons. That I think will be available soon. Salut!

Re: outputting TIFF-G images
Ok, yesterday I solved this problem by intalling jai tools. My error was
that I installed jai lib, but this doesn't supply any new service
provider, actually I don't know if this libs are really necessary.
Today I'll find a way to pass the page iterator to the tiff codec.
Salut!

I think the problem I have is that the IIORegistry has no service

Re: outputting TIFF-G images
Sorry if these questions are too obvious. En/na Jeremias Maerki ha escrit: One more thing: The TIFFRenderer currently uses the internal codecs from XML Graphics Commons to encode TIFF images. I understand you are talking about org.apache.xmlgraphics.image.codec.tiff.TIFFImageEncoder in the method stopRenderer() These do not support writing CCITT-G4 encoded images. We could switch to the ImageWriters I wrote for Batik and which are now available in XML Graphics Commons. They allow an abstraction from the underlying codec for image writing. There are implementations of the ImageWriter that write images through ImageIO ImageIOTIFFImageWriter? which might have CCITT-capable codecs available but the code will have to be extended to choose the compression algorithm. So you're talking about subclassing ImageIOTIFFImageWriter (into batik or into fop?) or adding code into? to use, for example, TIFFFaxDecoder? All in all, no easy solution to your requirement but certainly not much more than half a day of work. On 10.09.2006 12:54:46 Jeremias Maerki wrote: There's a configuration value you can set to modify the compression used but it's poorly designed (requiring an integer value) and undocumented. Furthermore, it does not support setting CCITT-G4 compression. Generating monochrome (1bit) images has also not been implemented, yet. To implement all this, changes would have to be made in: - Java2DRenderer.getPageImage(): Extract code into a protected method to instantiate the BufferedImage that we paint on. Right now, it always allocates an 24 bit RGB image with an 8-bit alpha channel. OK - TIFFRenderer.LazyPageImagesIterator.next(): Code to handle 1bit images. Uncoment the code for TIFFEncodeParam.COMPRESSION_GROUP4? simply return the BufferedImage generated in the protected method above (I think is this one)? or some other hack? - TIFFRenderer.configure(): provide better configuration using names for compression methods. What does this method does or have to do? I don't undertand why this method exists. It's reason is to log the compression? - Override the new protected method described above to create the Buffered image depending on the configuration. OK If you don't want to hack FOP code, the work-around is to convert the generated TIFF file after generation to CCITT format somehow. Obvious, isn't it? :-) On 08.09.2006 11:04:22 Oliver Hernàndez Valls wrote: Hi all, I'm working with fop to generate MTIFF text images.

Re: outputting TIFF-G images
Hi Jeremias,
I've been working a little with your suggestions.
What I have done is this little work:
1 -Extract code into a protected method to instantiate the BufferedImage
that we paint on. This methods signature is:
protected BufferedImage getBufferedImage(int bitmapWidth, int bitmapHeight)
2- Modify TIFFRenderer.configure() for selecting the BufferedImage type
in a new attribute.
3- Override the new protected method described above to create the
Buffered image depending on the configuration.
Here you are the code:

outputting TIFF-G images

Text justification in MTIFF output
Hi all, I'm working in a j2ee project where we need to generate text images. We use FOP 0.91 beta for creating MTIFF text images from dinamically generated xmls from database. As this images are inserted into public documents the text must be justified for a correct layout. The problem I have is that the document doesn't justify. For testing I'm using a little document that justifies if I generate the output as PDF. But when I generate the output as MTIFF with the same input, the text doesn't justify. Is there any problem whith justifying in MTIFF? any workaround? thanks in advance!! Oliver HV - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
