imager.drawmask - Function

2.3.1 Allows you do draw mask using the viewer

Description

A mask image is an image with the same shape as the other images but with values between 0.0 and 1.0 as a pixel value. Mask images are used in imager to control the region selected in a deconvolution.

drawmask is used to interactively draw regions over a template image which you want to allow deconvolution to occur.
