I have attached a patch so that iscan, scanning software for Epson scanners from Epson Kowa, will record the scanning resolution when saving .png files. Without this, some programs (e.g., hylafax) have to assume a resolution, and can be terribly wrong. (I was inspired to do this because only the lower left corner of my 400 dpi scans was going out, since they were assumed to be postscript standard 72dpi).
I'm not sure if all versions of libpng support pHYS; if not, it might be good to protect the code with some appropriate ifdef's. I had libpng10-dev (aka libpng2) as my development library when I compiled with gcc 3.3. Despite the name, I have used and applied the patch to iscan 1.5.2, gcc 3.2 version. I originally developed it against 1.5.1. I (c) in my name and release it under GNU Public License v2 or later; I believe this is the same license as the software it is patching, which is available at http://www.epkowa.co.jp/english/linux_e/lsd_e.html. Ross Boylan P.S. There are some other changes I'd like to make, like having iscan remember whether you selected png or pnm, and having it remember what directory you are in. I think that requires learning about gtk preferences, though. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
