The selections will be blurred (the blur is a Gaussian blur its rays can be controlled in the x and y directions). This procedure modifies the feathering setting. The sample criterion setting: SELECT-CRITERION-COMPOSITE (0), SELECT-CRITERION-R (1), SELECT-CRITERION-G (2), SELECT-CRITERION-B (3), SELECT-CRITERION-H (4),SELECT-CRITERION-S (5), SELECT-CRITERION-V (6), SELECT-CRITERION-A (7), SELECT-CRITERION-LCH-L (8), SELECT-CRITERION-LCH-C (9), SELECT-CRITERION-LCH-H (10). SELECT_CRITERION_COMPOSITE is the default value. This setting controls how color similarity is determined. If the sample threshold has not been set explicitly, the default threshold set in gimprc will be used. If an operation depends on the colors of the pixels present in a drawable, this setting controls what is "sufficiently close" to be considered a similar color. This procedure modifies the sample threshold setting. If antialiasing is turned on, the edges of selected region will contain intermediate values which give the appearance of a sharper, less pixelized edge. If antialiasing is turned on, the final selection mask will contain intermediate values based on close misses to the threshold bar at pixels along the seed fill boundary. This process continues until no more expansion is possible. (as determined by the Threshold & Sample criterion). Essentially, the color at the specified coordinates (in the drawable x and y coordinate of initial point) is measured and the selection expands outwards from that point to any adjacent pixels which are not significantly different A contiguous color selection is determined by a seed fill under the constraints of the current context settings. This creates a contiguous selection over the specified image. # Initial point for select contiguous color. Remove background (area with a uniform color).
