AW: rendering TIFF with FOP 2.0

[johannes.katel...@t-online.de]

OK, with the help of the FOP source I figured it out myself.

But to make it work I hat to patch the class 
org.apache.fop.render.bitmap.TIFFDocumentHandler.

I had to change visibility of the constructor to protected, because I derive 
from that class and need to call the constructor.

Can any of the developers please respond to this?

Or is this list not being read by the FOP developers?

Best regards

Johannes

Hello,

I have to move my application from FOP 1.1 to FOP 2.0 for generating PDF/A that 
validates OK.

I have successfully migrated PDF and PDF/A rendering to FOP 2.0. No major 
problem with that.

But now after migrating to FOP 2.0 the TIFF rendering that happens in the same 
application is broken. Unfortunately I can't figure out how to change the code 
to make it work again.

This ist the first thing that doesn't work anymore:

    protected class MyTiffDocumentHandlerMaker extends TIFFDocumentHandlerMaker 
{
    ...
            @Override
        public IFDocumentHandler makeIFDocumentHandler(FOUserAgent ua) {

            TIFFDocumentHandler handler = new MyTiffDocumentHandler(color);
            handler.setContext(new IFContext(ua));
            return handler;

        }

Problems:

1.   makeIFDocumentHandler(FOUserAgent ua) does not exist anymore in 
TIFFDocumentHandlerMaker
2.   TIFFDocumentHandler has no setContext method anymore.

Here's ist the second thing that doesn't work anymore:

   protected class MyTiffDocumentHandler extends TIFFDocumentHandler {
   ...
            BitmapRenderingSettings settings = getSettings();
            settings.getWriterParams().setCompressionMethod(
                    TIFFConstants.COMPRESSION_PACKBITS);

Problem:

TIFFConstants does not exist anymore.

Can't I find sample code or documentation somewhere that explains how to do 
this with FOP 2.0.

I need to render TIFF. And I need to set resolution, compression and color mode.

Thanks

Johannes
