Use the color to alpha tool with the background color to remove the fringe. Now cancel the selection, go to the Channels panel and deselect the Alpha channel, then go back to the layers panel. Use the fill tool to fill the selection with the main color. (Since you turned off alpha, this will not affect the transparent section.)
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.
Image editors can change the pixels to enhance the image in many ways. The pixels can be changed as a group or individually by the sophisticated algorithms within the image editors. This article mostly refers to bitmap graphics editors, which are often used to alter photographs and other raster graphics.
This vector-based (SVG format) image of a round four-color swirl displays several unique features of vector graphics versus raster graphics: there is no aliasing along the rounded edge (which would result in digital artifacts in a raster graphic), the color gradients are all smooth, and the user can resize the image infinitely without losing ...
The 256 available colors would be used to generate a dithered approximation of the original image. Without dithering, the colors in the original image would be quantized to the closest available color, resulting in a displayed image that is a poor representation of the original. The very earliest uses were to reduce images to 1-bit black and white.
When scaling a vector graphic image, the graphic primitives that make up the image can be scaled using geometric transformations with no loss of image quality. When scaling a raster graphics image, a new image with a higher or lower number of pixels must be generated. In the case of decreasing the pixel number (scaling down), this usually ...
