Get the desired background color set up (generally at the bottom of the toolbox). Shift click in any isolated areas that you want to remove (loops in 'O', 'P'. Now create a New Layer (have Foreground set to Red when you do this). Easy and quick: Add the desired text - suggest you 'pad' the ends of the text string with spaces (will look better when done). Usual technique: Do a wand select of the background. There should now be a nice green and alpha image with no trace of the blue left. Click OK after the color indicator on the Color To Alpha plug-in is changed to blue. If using Gimp for Windows, you’ll have to right-click on the destination button and select the Foreground - drag n’ drop doesn’t work. Click, hold, and drag from the color portion of this window to the color portion of the Color To Alpha plug-in. When you used the color picker to select the background, a window with the color popped up. Next use the Color Picker Tool to select the background color. If its not there, upgrade your gimp to 1.2.x. If its grayed-out, it means that you have an indexed image. If thats the background, then transparency data should have been exported. Its menu location is Filters -> Colors -> Color To Alpha, where means to right click on the image. The first step is to activate the color to alpha plug-in. Instead, may I suggest the rest of the tutorial? Step 1 ¶ You can go too far, and blend it back to something close, but this is time consuming. Anything short of the rightmost image has some blue in the pixel, which will stick out. You can spend hours trying to find something that will work perfectly, but you won’t. You can try getting rid of all the ugly pixels, but then you’ll end up with something jagged like on the right. The middle one is close, but there are some ugly visible pixels still. This looks somewhat neat, but not what we’re going for. The left one has a blue border around it. When these are filled, we are left with flat black and slightly blueish-green pixels between them, or no transition to black at all.Ĭompare each with the target image below. You’ll note that each of the three zoomed in selections above have varying amounts of the green-blue mix selected. However, when removing an anti-aliased object from its background is not a good idea, as shown above. The common approach to doing many things in GIMP is to first get a good selection. This tutorial doesn’t address the complexities of handling real-world photos in this manner, but does briefly discuss it at the end. To illustrate this, this tutorial will use the above images as source and destination. The aim is to show the advantages of using the color to alpha plug-in over selection-based techniques. This tutorial shows you how you can efficiently replace the background of an image with another in GIMP, through the use of the color to alpha plug-in. However, one can also use the eyedropper tool to pick a colour from anywhere on the desktop.Text and images Copyright (C) 2002 Seth Burgess and may not be used without permission of the author. Here, I used f3f3e9 as a background colour for plain colour filling. Click on the background colour rectangle in the upper half of the Tool Options toolbox window to change the background colour. So I could solve it in another way easily but want to learn how to do it in gimp, I just. (Tho I dont like ps, I cant use it as good as gimp). (In this respect, Adobe Photoshop is no different.) Hence, choose a colour which is compatible with the background on which the resulting picture will eventually be used. Ive encountered this problem several times in gimp, usually I would make it in paint fast or use photoshop where the bucket tool allows me to just fill the transparent bg. Some colour mixing will be inevitable and even desired. Do select BG colour fill and Sample merged and run a few tries while adjusting Threshold for best results. Within the Bucket Fill toolbox options, select Fill transparent areas only when necessary. Select the bucket fill tool or hit Shift+ B. The next step is optional and consists in filling the area that should become transparent with a plain colour first. This is done by selecting Layer → Tranparency → Add Alpha Channel. If this is the case, add an alpha transparency channel. Download the stamp png (make sure the Background is transparent) MockoFun is a. Some image types lack a transparency channel JPG for example. These classic rubber signature stamps allow you to choose any color ink. La trahison des images by fellow countryman René Magritte partly vandalised for the purpose of this tutorial.
