Lock grid settings

This dialog helps you to set up the lock grid, tile painting or symmetry mode. The lock grid will make the brush snap to the cross points of the defined grid size. The grid can be enabled using the grid tool at the toolbox.

Lock Grid

Width and Height define the horizontal and vertical spaces between the grid points.

Align Left and Align Top set the position for one grid point to define the position of the grid.

Get from Brush uses the current brush's width and height for Width and Height and the last position the brush was stamped down for Align Left and Align Top

Select either Grid, Tile Painting to enable the function you wish to use (see below).

The grid can be used for all drawing tools except airbrush. You can also use it together with the brush picker to easily pick up tile based graphic parts. There is an option that can be used to pick rectangular brushes correctly.

For example:

1. You have a grid 16*16 aligned to 0x0.
2. That means the brush picker always snaps to a multiple of 16 for both coordinates x and y.
3. If you want to pick up a brush from f.e. 16x16 to 31x31 this is not possible, because the crosshairs of the brush picker snap to 32x32.

To resolve this there is an option that automatically removes the rightmost and lowest pixel lines when picking up a brush this way. This option can be set in the preferences section miscellaneous.

When using Dot Lines then every line that is drawn (line, circle, rectangle etc.) will allocate every dot to the next matching grid cross point instead of drawing continously.


The symmetry tool helps you do symmetric drawings. You can select a point within the image that is the symmetry center. You can choose between two different symmetry modes, cyclic and mirror.

Cyclic mode
According to the number of dots you selected all dots will simply be drawn in a circle around the symmetry center. Up to 40 dots can be used at once.

Mirror Mode
The mirror mode also draws the number of dots you selected as a circle around the center, just like the cyclic mode. But additionally all dots will be duplicated by mirroring them. So if you select "1" for number of dots you will actually see two dots where the second one is drawn mirrored.

The symmetry tool only works with the the following tools:
· dotted/continuous drawing
· line
· poly line
· curve
· filled polygon
· flood fill
