Re: [Gimp-user] Scaling a foto

When I try to scale a foto in order to get it passport photo size it looses quality. Seems like a confusion about the scaling process. Your printer probably prints color at 300 or 600 dpi. When you work on that size of an image on your computer screen, your computer monitor probably only displays about 96 dots per inch (pixels per inch). That means that at 100% size, the photo will look HUGE on your computer screen at 100% zoom. That is how it is supposed to be. At 100% size on a printout from your printer, the photo will be much smaller, because your printer uses smaller dots to print the image. It's like a mosaic made of tiles. If I give you tiles that are the size of your fingernail, and tell you to create a smiley-face mosaic with those tiles, you'll have a fairly small mosaic. But if I give you the same number of tiles that are the size of dinner plates, your mosaic will be much bigger. But both mosaics have the same amount of detail, because you're working with the same number of tiles. Printer = small tiles (dots) Monitor = big tiles (pixels) If you use the scale image command to resize your image in GIMP before printing, you are losing quality and will print an inferior quality image. This may help you: Some people prefer to save the "huge" image from GIMP in PNG format, then import that photo into e.g. OpenOffice and scale the photo to size (in inches or cm) there. When you print, you'll have a nice high-res photo. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] WHat are my options, here
That is a tough one. I've done this sort of thing before, but in 3D software, and I already had a displacement (black to white) map to use for extruding the 3D surface. I then used a procedural texture color gradient on the Y axis of the model to apply my chosen colors to the model's contours, which could be controlled by editing the spacing of colors within the gradient texture itself. The final step was to render the image from the top view in a parallel camera mode, producing a flat 2D image with no perspective distortion. This could then be composited with the original topo map. I don't see any easy way to automate part of this in GIMP, other than perhaps using a blur filter to help with the blending between contours (doubtful if that will even give great results). It's also hard to try without seeing an example map, because some topo maps are a pain this way - they often have things like numbers overlaid on the lines, which creates many little gaps that must be compensated for when selecting a specific area. Hope you find a way. Marc ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

[Gimp-user] How to apply rotation to a pattern?
Is there a way to apply rotation to a pattern when it is used? For example, if I like a pattern but need to rotate it 30 degrees or so when it is applied to the selection. Any help here would be appreciated. Marc ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] How to apply rotation to a pattern?
When you select your pattern, press SHIFT+R. Then you can rotale the pattern either clockwise or counterclockwise. You can choose between adjusting the angle by hand, or by numeric value. Do you mean when I select the pattern in the Patterns palette? Shift+R there doesn't seem to do anything. I tried it on a selection within an image, but this is the normal rotation tool. How would that work for a pattern anyway? Can you demonstrate? Thank you, Marc ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Re: [Gimp-user] Pixelation of text
Larry, At what physical dimensions are you trying to print the text? The document should be at least above 200 DPI @ whatever physical dimension, to avoid obvious pixelation (assuming you do have antialiasing enabled). If you want to email the XCF to me, I can take a quick look at it.

[Gimp-user] Smoothing inked lines?
I've been scanning inks into GIMP, then moving them over to Inkscape for tracing to make the lines smoother. Is there a way to do this in GIMP alone? I don't mean vector tracing, just getting rid of the smaller abnormalities or fuzziness around my inked lines. I already scan at 600 dpi. Here's an example: http://www.friendlyskies.net/projects/comics/before-after.png Thanks! ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I'm using this trick for now until I get a direct potrace solution working. I also noticed that G'MIC has a "XSmooth Comic Lines" or something like that...sounded awesome but I wasn't able to get a good result from it. Maybe it's for a different purpose.
