Using a Tablet with a Pressure Sensitive Stylus
Picture Window automatically detects the presence of a Wacom or other compatible tablet on startup. You can tell if a tablet was detected via the Help/About Picture Window Pro dialog box. To be detected, a tablet driver must be installed and at least one tablet must be connected to your computer. If you connect your tablet while Picture Window is running, you may need to restart Picture Window to get it to recognize the tablet.
Generally, the tablet stylus works like a mouse where hovering the stylus above the tablet surface is like moving the mouse and tapping the stylus on the tablet surface is like clicking the left mouse button. Usually there is a button on the stylus that lets you right-click as well.
If your tablet has a pressure-sensitive stylus, you can use stylus pressure to modulate various brush-based operations in Picture Window. The commands that use brushes are the Clone, Paint, Smudge tools and the Mask paint tool. All brushes have four settings in common: radius, transparency, softness and spacing. Each tool that incorporate brushes has a setting for Stylus Pressure that lets you decide which brush setting, if any, you want stylus pressure to control. If no tablet was detected at startup, Stylus Pressure is set to Ignore and the other options are grayed out.
Ignore -- changes in stylus pressure have no effect
Controls Opacity -- increased pressure reduces the brush transparency, making the stroke more opaque
Controls Radius -- increased pressure increases the brush radius, making the brush larger
Controls Hardness -- increased pressure reduces the brush softness
Controls Flow -- increased pressure reduces brush spacing, making the brush apply more frequently as you drag it
