Here’s my recipe for getting the tablet kick started w/Synfig under win7.
- I have to open Synfig by double clicking on the application icon with the pen. If I use the mouse, then Synfig seems to ignore the tablet. (“No input device found”)
- Select File, Input Devices. Hopefully Wacom tablet pressure stylus will be listed (or something similar). Just selecting that with the pen seems to kick start the program to recognize Pressure, X tilt & Y tilt (otherwise, I only have 2 inputs listed - X & Y)
- Change the screen mode from Screen mode to window, save, then change it back to screen mode and save again. Close the Input device dialog.
- Select a tool in the dialog, like the ink tool or curve tool, and you should see it working. If not, repeat steps 2 & 3 again.
Hope this helps for you. I wish I knew why it was so picky.
