RE: [gentoo-user] how to szie an image so it fits on One sheet of paper (command line)
Well, obviously it does support jpegs out of the box, it just isn't doing quite what you were expecting it to do. Clear. Converting the image to a size of 72*8.5 results in an image that prints correctly. pnmtops does the scaling automatically as someone else pointed out. However I assume this down-scaling destroys a lot of detail from the original. So, I'd still like to know how I can reproduce a 300-dpi color scan on a 300- or 600 dpi printer. For if I understand you both correctly, with cups' lp or pnmtops I'm only printing 72dpi images Kind regards, Henk, -- [EMAIL PROTECTED] mailing list
[gentoo-user] how to szie an image so it fits on One sheet of paper (command line)
Hello, What I wanted to do was to scan a sheet of paper, and reproduce it on my printer, sort of a command-line copier. Since my printer is at 300 dpi, I thought it would be simple: scan the paper at 300 dpi, and enter: lpr scanned-paper. Hovever this gives the result of enlarging the image, so it now occupies 4 or 5 pages. So the question is, how do I estimate the resolution so that it will occupy only one page. or is there another commandline based solution? Thanks, Henk, -- [EMAIL PROTECTED] mailing list

(You can do 'pnmtops -scale 0.25 input |lpr' to explicitly scale it down; by default it will enlarge the image four times to change a 72dpi image to a 300dpi image, then reduce the result if it's too big for the page.) Nice thing about the netpbm programs is they all take standard input and output, so they can be used as chained filters and easily used for batch jobs. Might be useful if you gave us a better idea of what you were doing now, what programs you were using (including which print filters) and what intermediate formats. Thanks for the detailed answer. I have cups 1.19 installed, a hp deskjet 990c, and use the driver for hpijs obtained from linuxprinting.org. In the configuration menu i have set the printer to use 300-dpi color draft mode. For scanning I use scanimage from the sane package. The output was converted through ppmtojpeg like this: scanimage --mode=color -r 300 |ppmtojpeg -q 85 output.jpg identify from imagemagick tp;d ,e O jad 2532X35XX pixels, so to be safe I entered; convert -scale 2390 output.jpg output2.jpg finally: lpr output2.jpg with the result described earlier. In the cups documentation it is stated that cups supports jpegs 'out of the box', so I thought the procedure described was the logical thing to do. I'll give pnmtops a try tomorrow. Thanks again, Henk. -- [EMAIL PROTECTED] mailing list

[gentoo-user] phoenix crashes possibly solved
Recently gdk-pixbuf 0.22.0 appeared in the list of masked packages. Because my Phoenix kept crashing at least five times a day with a gdk error, I decided to try this new gdk-pixbuf and Phoenix hasn't crashed for two days. So if I were gentoo, I'd mark this version stable Henk, -- [EMAIL PROTECTED] mailing list

[gentoo-user] Mozilla/phoenix random crashes
Hello, I am having problems with both Mozilla and Phoenix (both through normal emerges). They crash at random moments. E.g. the last crash happend immediately after starting mozilla and pressing F11 to get to full-screen mode. It also sometimes happens after pressing 'enter' in the url entry box. I can't reproduce the problems. I'm using an athlon-1800XP+ and gcc with the athlon options. My graphics card is a hercules based on the ATI Radeon 9000-pro with the svga driver. Anyone having simular problems and/or suggetsiont? Opera and kde havn't crashed for weeks, so I don't think my system is unstable. Henk, -- [EMAIL PROTECTED] mailing list
[gentoo-user] gnome 2.2 font size
I emerged gnome 2.2 lately, and although it looks very clear, fonts are very large, even at 1024X768. When I change -dpi to something like 50, the logon screen from kdm contains very small letters, but as soon as gnome 2.2 appears they get big again. Anyone the same problem? how did you solve it?
