If the region to be searched is large and the search is repeated with high frequency, it may consume a lot of CPU time. If no match is found there, the search continues toward X2, column by column, until it finds a matching pixel. Slow mode: The search starts at the coordinates specified by X1 and Y1 and checks all pixels in the column from Y1 to Y2 for a match. If no match is found there, the search continues toward Y2, row by row, until it finds a matching pixel. However, prior to, the fast mode required X1 and Y1 to be the top-left corner.ДЇast mode: The search starts at the coordinates specified by X1 and Y1 and checks all pixels in the row from X1 to X2 for a match. Similarly, if Y1 is greater than Y2, the search will be conducted from bottom to top. In other words, if X1 is greater than X2, the search will be conducted from right to left, starting at column X1. The search order depends on the order of the parameters. The exception to this is cursors in games, which in most cases will hide any pixels beneath them. By contrast, pixels beneath the mouse cursor can usually be detected. The region to be searched must be visible in other words, it is not possible to search a region of a window hidden behind another window. For more information, see Runtime Errors.Д®rrorLevel is set to 0 if the color was found in the specified region, 1 if it was not found, or 2 if there was a problem that prevented the command from conducting the search. : This command is able to throw an exception if there was a problem while searching. In other words, the red and blue components are swapped. RGB: Causes ColorID to be interpreted as an RGB value instead of BGR. Note: The default Slow mode is unusable on most modern systems due to an incompatibility with desktop composition, which causes it to be orders of magnitude slower. Therefore, it might find a different pixel than that of the slow mode if there is more than one matching pixel. Finally, the fast mode searches the screen row by row instead of column by column. If the screen's color depth is 16-bit or lower, the Variation parameter might behave slightly differently in fast mode than it does in slow mode. Although color depths as low as 8-bit (256-color) are supported, the fast mode performs much better in 24-bit or 32-bit color. This parameter may contain the word Fast, RGB, or both (if both are present, separate them with a space that is, Fast RGB).ДЇast: Uses a faster searching method that in most cases dramatically reduces the amount of CPU time used by the search. If you specify 255 shades of variation, all colors will match. This parameter is helpful if the color sought is not always exactly the same shade. For example, if 2 is specified and ColorID is 0x444444, any color from 0x424242 to 0x464646 will be considered a match. VariationДЄ number between 0 and 255 (inclusive) to indicate the allowed number of shades of variation in either direction for the intensity of the red, green, and blue components of the color (can be an expression). Color IDs can be determined using Window Spy (accessible from the tray menu) or via PixelGetColor. The decimal or hexadecimal color ID to search for, in Blue-Green-Red (BGR) format, which can be an expression. Coordinates are relative to the active window unless CoordMode was used to change that. The X and Y coordinates of the ending corner of the rectangle to search, which can be expressions.

The X and Y coordinates of the starting corner of the rectangle to search, which can be expressions. Coordinates are relative to the active window unless CoordMode was used to change that.Д®ither or both of these parameters may be left blank, in which case ErrorLevel (see below) can be used to determine whether a match was found. The names of the variables in which to store the X and Y coordinates of the first pixel that matches ColorID (if no match is found, the variables are made blank).
