I was trying to resize a photo to 5x7 cm, using the scale image dialog, using centimeters... however the resulting image is smaller, and also the grid, when set to cm, (using 100% zoom) uses something that's smaller than a centimeter... what am I doing wrong? thanks in advance Lorenzo Hi, I think a possible reason can be: The resolution of your monitor is better than the resolution set in Scale Image window. I tried and experienced the same thing as you, and I got a 5x7 cm square with X and Y resolution 89 pixels/in on my monitor. The reason of this is that at 100% zoom level, gimp indicates each pixel of the picture on one pixel of the monitor, independently from resolution. Resolution and image size in pixels determine together the image size in cm. The meaning of image size of 5x7 cm for eg. 72 pixels/in when your monitor has a different resolution is that if you print your image with the set resolution, you will get the an 5x7 cm image. (72 pixel/in printed is quite poor resolution.) Abel ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

[Gimp-user] Removal of yellow and green eyes
Hi, what about variants of the remove red eyes filter? I take pictures of animals and they get other unwanted colours like green or yellow in their eyes. I suppose it would be feasible to introduce the opportunity to remove other colours but red. The remove red eyes filter is found under filter - enhance. I would be happy if there was two more filters: remove green eyes and remove yellow eyes. Or maybe a filter with an option to chose which colour to remove.

Re: [Gimp-user] Gimp-user Digest, Vol 98, Issue 3
Hi Don´forget the settings on the printer! I´did when I made some passport images, the printer settings was fill the paper. I made the biggest passport images ever seen. Flat screens in general seems to show smaller then 100% - To see a A4-paper as an A4 on screen I have to set 130% view on my Apple 21-screen.

Per Tunedal writes: I would be happy if there was two more filters: remove green eyes and remove yellow eyes. Or maybe a filter with an option to chose which colour to remove. I've wanted that too. You can do it the old way (the way we used before the red-eye filter was added in GIMP 2.4): select the pupil, perhaps with the ellipse selection tool, then use something like the Hue-Saturation tool to desaturate and darken. But it doesn't work as well on animal eyes as on human, because animal pupils are often much larger and is very light, and it's hard to make it turn black. Sometimes I have to paint in some black. Also, the animal pupil colors tend to be a lot less saturated than human redeye, so it might be harder to write a tool to select it in an automated way. Anybody have a reliable way to deal with animal greeneye?
