|Description:||The depiction editor's Color | Mask Color menu option allows you to define a mask color for the agent depiction being edited in the depiction editor. Masks are like filters or films of a given color that cover the cell a depiction inhabits. They are useful, if you wish to make part of the agent depiction transparent. Mask Color choices are described below.
The Color | Mask Color | None option specifies that the depiction of your agent will have no mask. Agent depictions with no mask completely cover agents below them.
The Color | Mask Color | White option specifies that the depiction of your agent will have a white mask. This means that the part of the agent depiction that was white will be transparent. The use of a white mask is good for making simulations where cars drive on roads, for example. Cars travel on top of roads and cover only portions of the road. The rest of the road should be visible underneath the car.
Upper-Left Pixel Color
The Color | Mask Color | Upper-Left Pixel Color option specifies that the depiction of your agent will have a mask of the same color as the upper left pixel of the depiction. Your agent depiction will become transparent at those pixels with the same color as the pixel in the upper left corner of the depiction.
The Gallery | Mask Color | Custom.. option allows you to select a mask color for your depiction. A Choose Color dialog will appear (shown below), prompting you to select a color from the available color palette and set it as the mask color.
Use the Choose Color dialog as you would use it for selecting a color (see Color | Color Chooser menu option)
