A higher scale factor creates a bigger BufferedImage.The end result is a
larger 72 dpi tiff.
you are correct. (since the viewer app we need to integrate with treats
those larger 72 dpi tiffs like smaller higher resolved ones, I did not
notice - and it still solves my problems ;-)
Though, this can be the first step to a higher resolved TIFF. I read some
docs about Graphics2D. The BufferedImage is resolution-independant. It is
simply a rectagle of pixels, with no information on what space it should be
displayed on. (as are some of the file-formats like GIF, BMP and others).
That means the way to higher resolved TIFFs could be:
1. calculate the scale factor, so that the renderer creates the correct
size in pixels (72 dpi = sf 100).
2. When writing out the TIFF, somehow set the resolution in the TIFF-file
Metadata to the higher dpi value. (need to look into this)
- That should result in a correct higher-resolved TIFF.

Is there any plan to add this feature in near future?
Sure. As I'm now FOP committer it should be one more FOP output format
(we
thought about more bitmap formats, supported by JAI/jimi, but I believe
the
only tiff makes sense as it supports multi-page images).
That's is definitely good news.
I think there is a need for other formats too. I see at my customer here
that they might want to get rid of multipage TIFF in favor of one JPG-file
per page.
Producing one file per page might be the way to go for the non-TIFF formats
(even for TIFFs that could be an option, since there are applications out
there that only support single page TIFFs).
just my $0.02 on the file format discussion.

Is the assumption correct, that this restriction is in the AWTRenderer of
FOP? -
I'm not sure actually. TIFFRenderer creates temporary BufferedImage when
encoding with fax compression, is that your case, I mean GROPU3 and GROUP4
compression schemas? For the rest compressions it uses directly
BufferedImage
created by AWTRenderer.

I was thinking of
adding this,
though I have not looked into it yet. Is it feasible at all with the
current FOP design?
Any help is greatly appreciated, feel free to modify sources. But not with
the
current FOP design, new one will make tiff generation much effective.
