Next use the Color Picker Tool to select the background color.
#Gimp set selected text color upgrade#
If its not there, upgrade your gimp to 1.2.x. If its grayed-out, it means that you have an indexed image. 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.
