Grid Brush Engine

../../../_images/gridbrush.svg

The grid brush engine draws shapes on a grid. It helps you produce retro and halftone effects.

If you’re looking to setup a grid for snapping, head to Grids and Guides Docker.

Brush Size

Grid Width
Width of the cursor area
Grid Height
Height of the cursor area
Division
Subdivides the cursor area and uses the resulting area to draw the particles.
Division by pressure
The more you press, the more subdivisions. Uses Division as the finest subdivision possible.
Scale
Scales up the area.
Vertical Border
Forces vertical borders in the particle space, between which the particle needs to squeeze itself.
Horizontal Border
Forces a horizontal borders in the particle space, between which the particle needs to squeeze itself.
Jitter Borders
Randomizes the border values with the Border values given as maximums.

Particle Type

Decides the shape of the particle.

Ellipse
Fills the area with a ellipse.
Rectangle
Fills the area.
Line
Draws lines from the lower left to the upper right corner of the particle
Pixel
Looks like an aliased line on high resolutions.
Anti-aliased Pixel
Fills the area with little polygons.

Color Options

Random HSV
Randomize the HSV with the strength of the sliders. The higher, the more the color will deviate from the foreground color, with the direction indicating clock or counter clockwise.
Random Opacity
Randomizes the opacity.
Color Per Particle
Has the color options be per particle instead of area.
Sample Input Layer.
Will use the underlying layer as reference for the colors instead of the foreground color.
Fill Background
Fills the area before drawing the particles with the background color.
Mix with background color.
Gives the particle a random color between foreground/input/random HSV and the background color.
