Hi Thomas, I misunderstood you, thinking #1 was not so easy either. But I'll go for that suggestion.I am almost ashamed to ask, but how do you that, and when...? Sorry, but I'm really a novice on graphics, and all thats concerning with it.
I think it will be enough to add the rectangle on the fly, just for the transcoding purposes. Where should this code be inserted and how does the lines to be inserted look line in TiledImageEncoder ? Or is it a big task to creata the rectangle ? And again, great thanks for helping me. /Gergely -----Original Message----- From: Thomas DeWeese [mailto:[EMAIL PROTECTED] Sent: Thursday, December 04, 2003 7:01 PM To: Batik Users Subject: Re: How to use "org.apache.batik.ext.awt.image.codec.tiff " ?

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.
