Module: Set Border
Description:
Sets border pixels to a specified value.
Left image is the input, and the right image is the result of setting a 1 pixel wide interior border to 255.
Connections:
Image
[required]
From this port, the input image is retrieved. For now, the only input type that has been implemented is HxUniformScalarField3.
Ports:
Size

Thickness, in pixels, of the border layer.
Where

If the border layer is on the inside, then the output image is the same size as the input, and the pixels that lie too close to the image boundary are overwritten to the new value. If the border is on the outside, then the output image is bigger, and no input pixel is overwritten.
Value

Value to set the border pixels.
Set

Pressing this button starts the computation.
Commands:
Additional options can be accessed when typing in the console Set_Border COMMAND_NAME. Typing the command again usually reverts back to original settings.
verbose
Displays timing information after the computation. Retype to hide info.
create
Runs the computation. Returns the name of the output, so it can be used in a script, such as set RESULT [Set_Border create].
