Syntax
PixelSearch[x,y,color,<optional>]
Description
Searches for the nearest pixel to x,y matching a set of conditions. Color and radius are required. Everything is given in decimal except for color, which must be lower case hexadecimal.
Optional Parameters
- -within # - Search for a pixel within # of the given color.
- -redwithin # - Search for a pixel within # red
- -greenwithin # - Search for a pixel within # red
- -bluewithin # - Search for a pixel within # red
- -upperleft - This will make the pixel search start in the upper left corner.
- -upper - This will make the pixel search start in the upper center.
- -left - This will make the pixel search start in the left border.
- -center - This will start the pixel search in the center
- -right - This will start the pixel search on the right border
- -lowerleft - This will start the pixel search at the lower left corner.
- -lower - This will start the pixel search on the center of the bottom border.
- -lowerright - This will start the pixel search in the lower right corner.
- -radius # - This is now effectively -center, -width (2*n), -height (2*n), and subtracts the X,Y position given by the radius.
- -width # - This sets the width of the box to used in the search.
- -height # - This sets the height of the box to be used in the search.
