Hi Al,
Are you saying that the exported PNG is of the correct size, e.g. 5x5 pixels? I
have to try that again.

Anybody know of a function which returns the color of the screen at a
given location? Simply pass it a point and get the color of that pixel,
kind of like a combination of the mouseColor function and the
controlAtScreenLoc function. I'd be happy if it only worked for points
on Livecode

Hey Klaus, that actually works quite well and it's a lot easier than
wrestling with the imageData of a snapshot. I wonder why the
screenMouseLoc is not mentioned as a related item in the documentation
for the mouseLoc?
Thanks,
Ray

Asks for a screen location in 2 comma delimited numbers and the returns
the colour at that location on your monitor.

Hi Ray,
This function doesn't involve moving the mouse cursor.
function screenlocColor
put the screenloc into myLoc
add 31 to item 1 of myLoc
add 31 to item 2 of myLoc
put (the screenLoc),myLoc into myRect
export snapshot from rectangle myRect to myPixels as PNG
set the text
Thanks Richmond - I believe this requires a mouse click, though, which
I'd like to avoid if I can.

Mark - I believe this is everything I need. Thanks! I especially like
you usage of the templateImage which keeps everything easy to work with
and no cleanup needed.

Hi Ray,
Now I'm thinking, why did I write a function for the screenLoc only? So,
here's a general solution.
// usage: pointColor(100,200) or
// pointColor(100,200) or e.g.
// pointColor(the screenLoc)
function pointColor thePoint
if the paramCount is 2 then
put param(1),param(2) into
Mark I'm having fun with this code. Just one question; why add 31
pixels as opposed to another number of pixels?

Here's another way:
on getPixelColor pPt
put the screenmouseloc into tOldLoc
put (item 1 of pPt) + (the left of this stack) into tloc
put (item 2 of pPt) + (the top of this stack) into item 2 of tloc
set the screenmouseloc to tloc
put the mousecolor into tColor
set the screenmouseloc
Hi Ray,
I wanted to keep the amount of data to be dealt with as small as
possible. The smaller the amount of data, the faster the function, I'd
assume. Unfortunately, it seems impossible to export snapshots smaller
than 32x32 pixels. Adding 31 pixels to the height and width of the first
Ahh, I understand. I didn't realize there was an issue exporting
snapshots 32X32.
And Jackie, thanks. Very clean solution. I just tried it and it works
very well.
