How do I create a 40x40 pixel monochrome mage for KMail?
I've noticed that several apps support images of the user, such as KMail, which supports a 40x40 pixel jpeg. I have a webcam, but it won't take a monochrome picture and it doesn't snapshot all the resolutions that it can display in. In particular, I tried the two lowest and the lowest, sqcif, isn't supported by my webcam and qsif seg faults. Those would have been 128x96 and 160x120. I figured that if I used the lowest resolution, I could crop out a 40x40 image. Kopete also supports a 200x200 pixel image, but I think it requires exactly 200x200, so 128x96 won't work. I thought that someone said they used kamera to take a snapshot with their webcam but Logitech webcams aren't listed. I can take one with pwcview, which is what I was talking about above. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

You can use ImageMagick's convert command to scale the image, and turn it into monochrome; see man convert for -resize and -monochrome parameters. It's even possible to use Gimp for this task. :-) Kopete also supports a 200x200 pixel image, but I think it requires exactly 200x200, so 128x96 won't work. You can use ! with -resize to force a specific image size, even if it violates the source picture's aspect ratio (which -resize usually keeps). I thought that someone said they used kamera to take a snapshot with their webcam but Logitech webcams aren't listed. Maybe you can use gtkam / gphoto2 to talk to the Logitech camera? I don't own one because I'm familiar with the fact that they are not standard-compatible and that's why not supported. I can take one with pwcview, which is what I was talking about above. You can even use a regular digital camera to take the photo, transfer it from the camera (or its CF or SD storage) and then postprocess it with ImageMagick. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Take a bigger image, convert it to greyscale, resize it down to the size you want. You could most easily do this with Photoshop, IrfanView, GIMP, ImageMagick, etc, but something like graphics/netpbm will work even on the FreeBSD command line Regards, -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
