Short for Portable Network Graphics, the third graphics standard supported by the Web (though not supported by all browsers). The compression algorithm used in the GIF format is owned by Unisys, and companies that use the algorithm are supposed to license the use from Unisys.* GIF also supports transparency, where the background color can be set to transparent in order to let the color on the underlying Web page to show through. With an animation editor, GIF images can be put together for animated images. GIF is better than JPG for images with only a few distinct colors, such as line drawings, black and white images and small text that is only a few pixels high. Unlike JPG, the GIF format is a lossless compression technique and it supports only 256 colors. Short for Graphics Interchange Format, another of the graphics formats supported by the Web. JPG does not work well on line drawings, lettering or simple graphics because there is not a lot of the image that can be thrown out in the lossy process, so the image loses clarity and sharpness. The user typically has to compromise on either the quality of the image or the size of the file. JPG images support 16 million colors and are best suited for photographs and complex graphics. The information that is discarded in the compression is information that the human eye cannot detect. JPG is a lossy compression technique that is designed to compress color and grayscale continuous-tone images. JPG is one of the image file formats supported on the Web. Just some examples whipped up in a few minutes.Short for Joint Photographic Experts Group, the original name of the committee that wrote the standard. These type of textures also seem to work well for layering two or three textures together with different layer modes.Īll in all, this is nice and simple, and fast way to create some colorful textures. Of course changing the gradient type, and the brush will have a big effect on the look of the texture, but so will more subtle things like the opacity of the brush, and the paint mode can make for some interesting effects. Offset that image one more time (or not,actually…), and your ready to go. But if you do, just repeat the above steps again and you should be fine. You will probabaly want to avoid painting at the edges of the image when you do this. You probabaly want to give it a bit of character so it looks more natural. The secret to making tileable images is to make this transition smooth.įor gradient painting with grunge brushes, this typicaly just means painting along those lines. Your image will now show what used to be at its edges at the center of the image. Then choose the convient “x/2, y/2” option, and hit OK. The easiest way to do this is to offset your image by half its height, and half its width. The hard part is making the image tilable. Fill the image completely if you dont want alpha poking though. If you want to stick to a very set pattern, your texture might look a bit more orderly. For this particular example, I used “Caribbean_Blues”. Pick one at random, you can get nice results from any of them. Now choose a gradient from the the gradient selector ( Dialogs -> Gradients). Of course, please experiment.įor example, lets choose the “Grunge 15” brush. I would suggest setting the spacing to about 80-120 or so. Get these for real fun with gradient brushes.īasically, just select one of those brushes, and se the spacing to something reasonable (most default to 10 or so). A very nice set can be found in the June 1999 edition of, in the brushes section. So called “grunge brushes” work quite well for this use. To really spice thigns up a bit, you need some more interesting brushes. Just filling in an image with a gradient brush is a good start for interesting textures, and you can make some nice ones that way.īut that gets a little boring after a while. You can also press the Gradient button to change the current gradient. Just check the option “Use Color from Gradient” and start painting. Gradient brushes can be accessed from the standard paintbrush dialog. Essentially, this is just the regular paint tool, but instead of painting with a constant color, it gets its color from a gradient and rotates through the gradient as you paint. The GIMP 1.2 series have a nice new feature I refer to as gradient brushes. Text and images Copyright (C) 2002 Adrian Likins and may not be used without permission of the author.
