Grid Layer

A grid layer shows a grid as a bitmap layer (raster) in the map using a color scale.

Select/Edit Color scale
Select and/or edit the color scale using the Color Scale Editor.

Smooth
The smooth factor is used for color scale only and is used to smooth the color scale to produce sharper discrete levels. When the smooth factor is larger than one, each node value is represented by more than one pixel. Example: if smooth factor is 2 each cell in the grid is divided into 2 * 2 = 4 pixels. The higher the smooth factor the sharper color levels. Note, this settings should be used with care. The higher the smooth factor the longer it takes to generate a color scaled bitmap.
