The edges of characters and other images with transparent background should not have shades of gray: these are normally used for intermediate colors between the color of the letter/image and that of the background, typically shades of gray being intermediate between a black letter and a white background. However, with, for example, a red ...
This can also be thought of as how much contrast is added at the edges. It does not affect the width of the edge rims. Radius affects the size of the edges to be enhanced or how wide the edge rims become, so a smaller radius enhances smaller-scale detail. Higher radius values can cause halos at the edges, a detectable faint light rim around ...
In computer graphics, anti-aliasing improves the appearance of "jagged" polygon edges, or "jaggies", so they are smoothed out on the screen. However, it incurs a performance cost for the graphics card and uses more video memory. The level of anti-aliasing determines how smooth polygon edges are (and how much video memory it consumes).

A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1]
Corel Photo-Paint is a raster graphics editor developed and marketed by Corel since 1992. Corel markets the software for Windows and Mac OS operating systems, previously having marketed versions for Linux [1] (Version 9, requiring Wine).
Edge enhancement is an image processing filter that enhances the edge contrast of an image or video in an attempt to improve its acutance (apparent sharpness).. The filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge.
The lasso (or "free form selection") is an editing tool available, with minor variations, in most digital image editing software [1] and some specific strategy games.It is often accessed from the standard main menu (in Photoshop, [2] Paint Tool SAI, [3] and GIMP, [4] as common examples), by clicking the icon of a dotted line shaped like a rope lasso, from which the common name arises.
