It's not too complicated, just be careful to make sure you set you save location as different to where it is reading the file from until you know you have everything set correctly (or backup before starting) as it has no preview.Īlso it seems they have removed it from 18.04 for some reason! :(ĮDIT: Plus either I'm being an idiot or the dev has changed/removed the actual hompage and there's no Free Download link like it says to find and click on. I have used it for resizing files for upload and similar automated batch tasks like that. If you were to invert the circle then everything outside the circle becomes the new drawn mask and combines with the parametric using “or” or “and”, ie inclusive or exclusive.For bulk processing I would definitely go with Phatch. So once you start thinking “and” vs “or” then you can sort out what changing polarity might do when the various elements are combined… For example you have a parametric mask and a circle drawn somewhere. The individual drawn elements of the final drawn mask are controlled by the settings used in the mask manager… Now lets say instead you use inclusive… well this is the exact same process but using “or” logic… So in this case the mask described above would be the blue sky, the blue water and anything not blue but selected by the entire drawn mask. So setting exclusive uses “and” logic to combine the drawn mask and the parametric mask as well as the individual channels of the parametric mask.
There is a mode called exclusive inverted which will give you the inverted mask of any overall mask you make while the setting is exclusive. Drawn sub elements interactions are controlled by the mask manager to derive the drawn mask and parametric channels combine using the selected mode logic in this case “and” when it is exclusive. In addition it determines how all the parametric channels are combined with each other when the overall parametric mask is constructed… So D + P mask = final mask and they are treated with an “and” logic if you set the mode to exclusive. You mask with a parametric mask but the water in the shot is blue and so is the sky so you use a drawn mask around the sky area so that pixels in the mask are blue and only where it is blue inside the drawn area… This mode is the logic for how the overall drawn mask and the parametric mask are combined to give the final result. Exclusive and Inclusive… If exclusive is chosen this is like using “and” as the operator so for a pixel to be masked it must satisfy all the requirements of every mask element introduced… So lets say its sky. THen you have the parametric mask with several channels… These can be defined and inverted with polarity for each channel… THe key is the mode used for the mask. THe final drawn mask is a composite of all the individual shapes… how these interact with each other to make the final drawn mask is controlled in the mask manager. These in turn can each be derived from the combination of elements added. THe final or global mask in your module is the combination of the “DRAWN” mask and the “PARAMETRIC” mask or only one or the other if you just use one type. There is a bit of nuance to the masking in DT…Try to think of it this way which may or may not help…
