Honestly, my needs are absolutely not so big at all concerning the quality of the TIFF. Actually I just plain text I want to visualise, on white/transparent background with black text. So as long as the text can be seen, I wil be satisfied :=)
Huh, isn't there any easier way to achieve this than the two suggestions you are giving :=) ? Otherwise, I am afraid I will mailbomb this/other forum for a while...
I gave three, add a white rectangle to the SVG (perhaps on the fly
only for transcoding purposes), use software that understands alpha channels and write code to flatten (implement the background color
hint basically).
I can understand that #2 may be out, #3 may be more work than you want to do (although it might open the door for other enhancements like going to 1bpp), but what is wrong with #1?
As I mentioned, I just need to be able to see the text. In the "worst" case maybe other colors can be used to than black/white if it makes a solution easier.

Actually you are seeing opaque black text on a transparent black background :) You either need to insert an opaque white rectangle into the SVG source (before everything else). Use software that understands alpha channels, or write code to 'flatten the image' (* this is non-trivial).
tit.addTranscodingHint( ImageTranscoder.KEY_BACKGROUND_COLOR, // ADDED
MYSELF
Color.white );
This would be one of the bells and whistles not supported by the tiled transcoder.
The TIFF is now just 14000 byte ( suspiciously small...). What does the KEY_WIDTH and KEY_HEIGHT mean ?
This is the size of the image in pixels. So you are generating a 100x100 pixel image with 4 channels of 8 bits (1byte) each:
100*100*4*1 = 40,000 bytes uncompressed I could easily believe 14,000 bytes compressed. Although 100x100 may not be close to big enough for your needs.
By the way, setting the background Color.white is not seen in the result.
Again, million thanks for your help ! Now it's just the final step left.
So
if you could help me with this, I would be REALLY happy :=)

You are right, I meant baseclass method. I have removed the batik.jar from FOP, but then I just got some other error.
java.lang.NoClassDefFoundError: org/apache/batik/i18n/Localizable at java.lang.ClassLoader.defineClass0(Native Method)
> [...]
Exception in thread "main"
The jar's I've included to the classpath is the follow
batik-1.5.zip/batik-1.5/*.jar batik-1.5.zip/batik-1.5/lib/*.jar
Are you sure you have all of these (there are a lot of them). In particular the above mentioned class is from 'lib/batik-util.jar'
batik-1.5.zip/batik-1.5/extensions/*.jar
When I removed the batik.jar ( FOP version ) I could find the
"KEY_INDEXED"
field as well.
I really appreciate your help !
