- The Tablet preferences now contains two thresholds which require some
- explaination.
-
- Using the two thresholds, you can set up the tablet so that you can draw
- with a light touch while still requiring a much harder press to activate
- gadgets.
-
-
- Pressure Threshold
-
- This is the pressure required to start freehand drawing in OpalPaint. The
- pressure range will be scaled linearly above this threshold, so you will
- not experience a jump in pressure when you start drawing, but you should
- make this threshold as small as possible to give you a large range of
- pressures to work with.
-
- For example if you are using a wacom tablet which has 64 levels of pressure,
- and set the threshold to 10, the physical pressure values (i.e. as reported
- by the tablet) below 10 will generate a 0 pressure level to OpalPaint. The
- pressure values from 10 to 64 will be scaled to a range of 0 to 64 for use
- in OpalPaint.
-
- The pressure values generated by the tablet will vary form tablet to tablet,
- you may find that some wacom tablets return a value as high as 4 or 5
- for pressure when the stylus is not touching the tablet surface. If you
- find that OpalPaint is drawing when you are applying no pressure, you will
- need to increase this threshold.
-
-
- Click Threshold
-
- This is the amount of pressure required to generate a left or right mouse
- button click. This value must be greater than or equal to the pressure
- threshold.
