I have modified the script for combining an Intuos 4 Medium and TabletMod Large:
Download the script as modified for use with I4M and TabletMod Large V3 here http://tabletmod.com/Downloads/TModLargeforI4M.ahk
To use the I4 Medium with the TabletMod Large Kit, you will need a sheet of card 2-3mm thick to place between the tablet and the foil shield - this ensures the tablet is close to the LCD Panel. You will then need a foam board spacer (2 stacks of 5mm thick approximately 40cm long and 3.5cm wide). Use this to position the tablet inside the enclosure ensuring the active area is behind the screen. You can measure and use further spacers in the same way to fix the tablet in place.
Note this script presumes your TabletMod Large is also the primary display.
To fine tune the position of the active window, you will need to edit these two lines:
WinSet, Region, 0-0 1439-0 1439-899 0-899 0-0 1-130 980-130 980-755 1-755 1-130, TheBlack
WinSet, Transparent, 0, ahk_class Shell_TrayWnd
The values 0-0 1439-0 1439-899 0-899 0-0 define the outer border of the black boundary - a closed loop of x-y coordinates. The values 1-130 980-130 980-755 1-755 1-130 define the inner boundary of the border giving the dimensions 979x625 noted above.
@ Pesho, how do you turn a script into an exe file ?
