MBS( "GMImage.FindColorInRow"; ImageRef; x; y; color { ; Invert; Tolerance } )


Parameter Description Example value
ImageRef The image reference number. 1
x The x coordinate. Zero based from 0 to GMImage.GetWidth-1. 10
y The y coordinate. Zero based from 0 to GMImage.GetHeight-1. 10
color A color value.
This can be a string in the following format "HSL h s l a", "YUV y u v a", "RGB r g b a", "MONO m a", "GRAY g a" or "COLOR R G B a". Alpha value a is optional. Range of values is 0 to 1.0 except if you use COLOR where RGB values are 0 to 255.
Starting with version 5.4 of our plugin, you can use hex notation. # followed by 2 digits for red, green, blue and optional alpha, e.g. #FF0000 for full red.
"RGB 1 0 0"
Invert Optional
If 0, we find first pixel matching your color. If 1 we find first pixel not matching the color. Default is 0.
Tolerance Optional
The tolerance for comparison. Normally a small value like 3. So if color is 255, 255, 255 and pixel is 252, 252, 252 we have a match for tolerance being 3.


Returns position or error.
