Hi again,
Can anyone tell me if there is a way of getting the rgb value of a
specified pixel within a jpg graphic file that has been imported
into rev?
I have read the docs but cannot see anything that tells me if I can
or how...
The two items needed are....
mouseColor function:
Returns the color of the pixel that the mouse pointer is over.
screenMouseLoc property:
Specifies the position of the mouse pointer relative to the screen.
(Also allows you to set the mouse to a specified location)
Example:
put the screenMouseLoc into varMouseCoordinates
put the left of this stack + 225 into varStackH
put the top of this stack + 40 into varStackV
set the screenMouseLoc to varStackV,varStackH
put the mouseColor into varColor
set the screenMouseLoc to varMouseCoordinates
answer varColor
Grab the current location of the mouse, then get the left position of
the stack and add how many pixels to the position that you need to
the pixel you want, and then top of your stack plus how many pixels
to the pixel you need, then move the mouse to that position, then
using the mouseColor, get the color of that pixel, then put the mouse
back where it was when you started.
