Then either grow the selection by one or two pixels (using the Selection menu) or select the main color and invert the selection. The idea is to select both the newly transparent portions and the fringe around the foreground color. Use the color to alpha tool with the background color to remove the fringe. Now cancel the selection, go to the ...
Force it to be RGB: Gimp > Image > Mode > RGB, click. Delete the grey : Colors > "color to alpha" pop up > uncheck "preview", click on the horizontal color rectangle > "Color to alpha color picker" pop up> bottom right corner, click on the icon eyes dropper > choice you color of to delete (some grey pixel in a flat plain) > validate.
A screenshot of the GTK+ 2 color picker. A screenshot of the Qt color picker. GIMP color picker.. A color picker (also color chooser or color tool) is a graphical user interface widget, usually found within graphics software or online, used to select colors and, in some cases, to create color schemes (the color picker might be more sophisticated than the palette included with the program).
Colors can also be selected using hexadecimal color codes, as used in HTML color selection. GIMP has native support for indexed color and RGB color spaces; other color spaces are supported using decomposition, where each channel of the new color space becomes a black-and-white image.
A 2-bit indexed color image. The color of each pixel is represented by a number; each number (the index) corresponds to a color in the color table (the palette).. In computing, indexed color is a technique to manage digital images' colors in a limited fashion, in order to save computer memory and file storage, while speeding up display refresh and file transfers.
The Color Dodge blend mode divides the bottom layer by the inverted top layer. This lightens the bottom layer depending on the value of the top layer: the brighter the top layer, the more its color affects the bottom layer. Blending any color with white gives white. Blending with black does not change the image.
It saves all of the data the program handles related to the image, including, among others, each layer, the current selection, channels, transparency, paths and guides. Prior to version 4 (GIMP 2.10.0, released on 2018-04-27), the saved image data are compressed only by a simple RLE algorithm, but GIMP supports compressed files, using gzip ...
In computer graphics, color quantization or color image quantization is quantization applied to color spaces; it is a process that reduces the number of distinct colors used in an image, usually with the intention that the new image should be as visually similar as possible to the original image.
