Hi,

can you please file in a Jira entry, attaching your material (test
case,  patch, etc)

This will ensure that nothing will be lost or omitted.

> 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?

> 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.
