Re: [Gimp-user] Pixelation of text

I am learning to use GIMP 2.6 on a Windows XP professional machine, a Dell. It'd be helpful if you could post the file online somewhere and send us a link, so we can see it. But as a guess: have you checked the Antialiasing checkbox, in the Text toolbox/palette? And, is your zoom level (on the image's View menu) set to ~100%? If you're zoomed way in it may look pixelated, even though at the actual size (100%) it really is smooth. Also, if the image mode (on the image's Image menu) is set to something other than RGB, changing it to RGB may help. If none of that helps, post the file online, and/or give us some more details. -- Anthony DiSante http://encodable.com/ http://nodivisions.com/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

No, it's an RGB-mode image; it's just that the only colors I'm using in it are white and gray.

Your unsmooth gradient has a much smaller range than the image of the smooth gradient you are comparing it too. I don't think that's it either. Here's the smooth one again, along with a new one created in GIMP with the same dimensions as the smooth one: http://nodivisions.com/stuff/ext_posts/smooth-gradient.jpg http://nodivisions.com/stuff/ext_posts/gimp-unsmooth-gradient-smaller.jpg That one's better, but still has more visible striations than the non-GIMP image. Or by range are you referring to white-to-gray vs. white-to-blue? Am I running out of intermediate colors faster because white and gray are more similar than white and blue? Ideally what I'd like is a white radial gradient with a transparent background, approx. 800px wide and 25% opaque, which I could then overlay on any colored background in different situations. But I guess the color of the background will affect how smooth the gradient appears. Still, I can't seem to re-create that non-GIMP smooth gradient using GIMP, even on the same color background.

On what display are you viewing these images? Your gradients only use a small subset of the RGB color-space (about a few dozen colors). Most modern displays are not able to render all the 16 million colors of the 24bit RGB color-space. Modern LCD panels, unless you spend a lot of money, are limited to somewhat like 20 or 18 bits. So that will further reduce the amount of colors used to display your gradients. If you enable dithering and look at the results on a good monitor, favorably a well-calibrated CRT, then the gradients should appear reasonably smooth.

[Gimp-user] GIMP's gradients are not smooth?
Hello, I'm trying to create a smooth radial gradient in GIMP. I'm doing what I guess is the obvious thing: use the Blend/Gradient tool, set the shape to Radial, and draw it. This gives me a decent gradient, but it's not actually smooth. And it's especially unsmooth when I set the gradient layer's opacity to ~25%, which is where I want it to be for the effect I'm trying to achieve. Here are my files: http://nodivisions.com/stuff/ext_posts/gimp-unsmooth-gradient.jpg http://nodivisions.com/stuff/ext_posts/gimp-unsmooth-gradient.xcf.gz As you can see, there are obvious striations there, rather than a smooth gradient. What am I doing wrong? I've tried it with and without dithering, adaptive supersampling, etc; none of that seems to improve it. I'm using GIMP 2.6.7 on Ubuntu, if that makes any difference.

Does anyboy know simply :) how it works with the picture ? what is more (or less) in my testing of cubic vs linear, cubic was slower not best. cubic produced a fuzzy image and linear seemed to produce the best resized image. This is purely anecdotal, but for what it's worth, a while back I was trying to determine which scaling filter to use in a script to do batch-resizing with ImageMagick. I tested every filter with a couple of my digital photos as samples, in ImageMagick and PaintShopPro (IIRC), and to my eye Lanczos was the best; it was certainly at least *among* the best. -Anthony DiSante http://encodable.com/ http://nodivisions.com/ ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] scrolling thru fonts in FreeType plugin
Hello, Something about GIMP's FreeType plugin has annoyed me for a long time: after typing in my text, in order to see it in the various fonts, I can't just click on the first one and then press the down-arrow key. When I do that, the selection-outline moves down to the next font in the list, but doesn't actually select the font -- I need to press the spacebar to select it. So, instead of just pressing the down-arrow repeatedly to see each font, I have to press down-arrow,spacebar...down-arrow,spacebar...down-arrow,spacebar... Is there something wrong with my setup (in GIMP, or a GTK preferences file, or something)? Or is this the same way it works for everyone else here? If so, why on earth is it set up this way?? I'm using GIMP version 2.2.6 and FreeType plugin version 0.6, under GNOME 2.10 on Gentoo Linux. (And it's a 2.6.12 kernel on a Pentium-III system, but I doubt that matters...) Also, if there's a more appropriate place to ask this, please let me know; I wasn't sure if it would be the mailinglist for FreeType itself, and there's no sort of contact info whatsoever on freetype.gimp.org.
