The Pixel Tool draws pixel-aligned, hard-edged lines. This is in contrast to the Paint Brush Tool which may have a slight pixel variance due to its antialiasing.
Settings
The following settings can be adjusted from the context toolbar:
Width—the line thickness in pixels. Type directly in the text box or drag the pop-up slider to set the value.
Opacity—how see through the brush is. Type directly in the text box or drag the pop-up slider to set the value.
Flow—how fast the brush effect is applied (1% is very slow, 100% is immediate). Type directly in the text box or drag the pop-up slider to set the value.
Hardness—how hard the edges of the brush are. The brush appears softer as the percentage decreases. Type directly in the text box or drag the pop-up slider to set the value.
More—click to display the Brushes dialog to access advanced brush settings.
Force pressure to control size—Click to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
Stabiliser—enables stroke stabilisation using either a Rope stabiliser or Window stabiliser mode; the former drags the stroke end by a 'rope' to smooth the stroke but lets you introduce sharp corners at increasing rope Length (radius) values by redirecting the slackened rope; the latter will smooth the stroke by averaging sampled input positions within a Window whose size is configurable.
Symmetry—when set to greater than 0, repeats the brush stroke around a number of axes (defined by the symmetry value). The centre axis point can be repositioned by click-dragging it.
Mirror—with symmetry enabled, causes brush strokes to be mirrored along the X and Y axis.
Lock—when checked, prevents the symmetry line from being moved.
Blend mode—changes how the applied pixels interact with existing pixels on a layer. Select from the pop-up menu.
Protect Alpha—when checked, you are not able to paint on the current layer's transparent regions.
Alternate—changes the behaviour of the alternate modifier (-Click):
Erase—erases created pixels.
Background colour—temporarily switches to the background colour in the swatch.
Undo from snapshot—paints-in from a chosen snapshot (see Using snapshots).
