About Pen Pressure Curve Customization

When you use a pressure-sensitive tablet with the Brush, Eraser, Pencil and Stamp tools, Harmony takes the amount of pressure you put on your tablet pen in account as you draw. It uses this information to determine the thickness of your drawing stroke. For example, while using the Brush tool, the harder you press on you tablet pen, the bigger your brush strokes will be, and vice versa.

To determine the thickness of your drawing strokes, it uses your drawing tool's Minimum Size and Maximum Size parameters, which can be set in the Tool Properties view. The thickness of your drawing stroke is always going to vary between those two parameters, based on how much pressure you put on your tablet pen.

By default, the size of your drawing strokes is directly proportional to the amount of pressure you put on your pen. It is calculated using this simple formula:

size = x + ( a ÷ b ) × ( y - x )

This means that if you apply 25% of the pressure your tablet pen can detect, the thickness of your drawing strokes will be 25% of the way between your tool's minimum size and its maximum size. Likewise, if you apply 75% of the pressure your tablet pen can detect, the thickness of your drawing stroke will be 75% of the way between your tool's minimum size and its maximum size.

Harmony allows you to customize the way it processes the pressure you put on your tablet pen into the thickness of your drawing strokes. You can do this by tweaking the pressure curve in the Pen Pressure Feel dialog.

Depending on how you hold and use your tablet pen, this may allow you to have better control over the thickness of your drawing strokes. For example, if you tend to put a lot of pressure on your pen, you may want Harmony to let you draw thinner lines unless you apply even more pressure than you usually do. Likewise, if you tend to put very little pressure on your pen, you may want Harmony to generate thicker lines unless you apply even less pressure than you usually do.
