Well, he could, if he didn’t wanted an average value of some more pixels, and, calculating an average via screenMouseLoc is really slow. Exporting a rect to an image is fairly quick though
Found the following in a stack: # Calculates the average color value for an image # pID should be the long id of the image we want to get the average from function imageAverageValue pID put the imageData of pID into tData put the number of bytes of tData / 4 into tNumPixels # Sum all pixel values repeat with i = 0 to tNumPixels - 1 add byteToNum(byte i*4 + 2 of tData) to tResult["red"] add byteToNum(byte i*4 + 3 of tData) to tResult["green"] add byteToNum(byte i*4 + 4 of tData) to tResult["blue"] end repeat # Calculate mean value repeat for each item anItem in "red,green,blue" put round(tResult[anItem] / tNumPixels) into tResult[anItem] end repeat return tResult["red"], tResult["green"], tResult["blue"] end imageAverageValue So to get the mouse average color in a square ± 2px from the mouseLoc we could do: function getMouseAverageColor pSize if pSize is empty then put 2 into pSize put globalLoc(the mouseLoc) into tLoc if there is no image "averageColor" then create invisible image "averageColor" put the long id of image "averageColor" into tID export snapshot from rectangle item 1 of tLoc - pSize, item 2 of tLoc - pSize, \ item 1 of tLoc + pSize, item 2 of tLoc + pSize to image "averageColor" return imageAverageValue(tID) end getMouseAvaregeColor Happy coding! :-Håkan On 7 Jan 2019, 15:35 +0100, dunbarxx via use-livecode <use-livecode@lists.runrev.com>, wrote: > A kluge, but couldn't you: > > on mouseUp > set the screenMouseLoc to "200,200" > answer the mouseColor > end mouseUp > > I just threw this together, so you might want to restore the original > mouseLoc, and locking the screen might be useful. > > Craig Newman > > > > -- > Sent from: > http://runtime-revolution.278305.n4.nabble.com/Revolution-User-f278306.html > > _______________________________________________ > use-livecode mailing list > use-livecode@lists.runrev.com > Please visit this url to subscribe, unsubscribe and manage your subscription > preferences: > http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
