External raster mask works fine:
I have a .pfm file that masks the foreground and import the .pfm file with the module “external raster masks”. In the colorize module, I select “raster mask /external raster masks”. The external raster mask is applied to the image as expected.
Can not combine with drawn mask:
I want to adjust the raster mask with a drawn mask, adding and deleting parts of the mask. I am unable to combine the external raster mask with a drawn mask (brush, ellipse, etc.) or a parametric mask to refine or adjust the selection. I can only use the raster mask by itself.
Is there a way to modify a raster mask later in the pipeline?
