So far, I have not discovered the difference between using raster masks and using the mask manager in DT. Both offer a convenient way to re-use a previously designed mask. However, I have so far only done this with drawn masks, but I assume there’s no difference.
For drawn masks it doesn’t matter. Raster masks matter when you use a parametric mask and then want to reuse the same mask in another module.
- Performance : reusing shapes involves re-cumputing the same mask for as many modules are using them. Raster masks are computed only once and re-used as-is.
- Lazyness : when using advanced masking with boolean operations, using raster masks inherits all the boolean ops too and saves you the trouble to reset them later.

ThAnk you Aurelien! Great advice. What is a boolean op? I know about the principle of boolean algebra but could you give me an example of a boolean mask op?
Thank you, that’s awesome! I didn’t know about the grouping option in masks. That opens up new opportunities.
