Shape

There are three Shape choices: Diamond, Round and Square (the default). Diamond and Round shapes will only be visible when you lower Size Ratio X/Y to about 0.6 (Diamond) or 0.5 (Round).

Block width, Block height

Here you can set the desired width and height of the blocks, in pixels.

Normalt er breidde og høgde lenka saman, vist med lenkesymbolet. Du kan fjerne samanlenkinga ved å klikke på lenkesymbolet.

Size ratio X, Size ratio Y

Horizontal/Vertical size ratio (0.000-1.000) of a pixel inside a block. Default value is 1.000. The number of blocks remains the same; so, if you change ratio, block size changes, and missing pixels are replaced with the background color.

Offset X, Offset Y

Horizontal/Vertical offset of the shapes in pixels inside a block.

Background color

Default background is that of toolbox. You can change it by clicking on color source, which opens a color selection dialog, or picking a color using the color picker on the right.

Note that you can change the background color to be partially or completely transparent by lowering the alpha value in the color selection dialog. This can lead to interesting effects provided the layer you are working on has an alpha channel.
