Code: Select all

ExitFlag = 0
While ExitFlag == 0
     tv_WaitButton
     parse result ButtonState X Y
     IF ButtonState == 3 || ButtonState == 4
         ExitFlag = 1
     ELSE
          tv_GetPixel X Y
          parse result R G B A
          IF A > 0
               tv_SetAPen R G B A
 //          tv_warn "pixel color = " R G B A
          END
     END
END

The button will sample the RGBA value of the current layer/current pixel and set the APen color.
Click RMB to exit. Or if your stylus is setup, hold down the lower switch on the barrel and click the tip.

tv_UnLockMouse

Click RMB to exit. Or if your stylus is setup, hold down the lower switch on the barrel and click the tip.

1st Update to script: you may also just click outside the Project window to exit.
2nd Update to script: added arrow + question mark cursor while selecting layer color reverting to normal cursor on exit.

Its easy.
Let's say you named your custom panel "ColorStuff" and in the panel you put your button named "LayerPixPick".

Open the Configure Keyboard Shortcuts panel. In the Search box type "LayerPixPick" which will show you The Custom Panel name... click on "(+) ColorStuff" and select the "LayerPixPick" button name which will highlight.
Pick a shortcut key you want to assign the button to, let's say "Shift P", and OK, to save the Shortcuts list. From there you link Shift P to a button on your device or stylus like it was any other shortcut key.

If you choose a background pixel (one which has zero alpha value) the color is returned as black.
So, the following script traps when you click on a background pixel or as might happen, you are not on the layer you think you are on.
The script warns that no color was found (instead of making your APen black).
In that case you might have to confirm that you are on the layer you think you are AND/OR click again to sample the color.

Simply replace the other embedded script with the following:

Code: Select all

tv_LockMouse 4
tv_WaitButton
parse result ButtonState X Y
tv_GetPixel X Y
parse result R G B A
tv_UnLockMouse
IF A > 0
    tv_SetAPen R G B A
ELSE
     tv_warn "no pixel color found"
END
