There is no dogged resistance. I just had the impression that you believed that storing selections would be the only use of channels. no, my diagnosis is that it is just abuse of channels. It is more like a useful side-effect of it. Perhaps it makes sense to make it more obvious how to save and restore selections, but we also need to make sure that we are not taking away important features. Channels is really an area where GIMP is lacking. If we want to be taken seriously, then there should be much more emphasis on channels. Removing them from the default UI is not a step towards that. so we were solving two different problems. You were resurrecting the channels and I was resurrecting the selections. looking at channels: I am not the one to come up with suggestions what else channels can do. a discussion of this would be welcome. what I can say is that how are we going to get graphical information into channels needs to be brought up to a level that there is for layer masks (but taking the global nature of channels into account). I was reviewing the transport of graphical information between layers, masks, selections, channels. the weaker part seems to be the channels and also the alpha channel, I am still mesmerised that it cannot be made visible, tangible like the layer mask. --ps founder + principal interaction architect man + machine interface works http://mmiworks.net/blog : on interaction architecture ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Having them in one dialog is admittedly somewhat confusing, but it is an established standard for pixel manipulation programs. I don't think we should change that. It would only waste space. Though just because photoshop does it that way doesn't make it the best way. It seems to be a hugely confusing area for ps users, too. It wasn't until I started digging into the PDB that I discovered that channels are just greyscale drawables, and handled as such the software. I think that all of the channel use cases should be examined before deciding how these should act. My own experience with channels is limited to: 1) Image decomposition for masking/converting to greyscale 2) Saved selections Possibly because that is all the gimp documentation talks about... In the glossary, http://docs.gimp.org/en/glossary.html#glossary-channels and http://docs.gimp.org/en/glossary.html#glossary-masks it refers to these two uses. Sven mentioned other uses, like spot colour and halftoning. I can't find any references on using gimp channels for spot colour, in fact google only finds me claims that a weakness of gimp is that it does NOT support spot colours. -Rob A ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

If you can get your hands on the GIMP User Manual version 1.0, the book by Karin and Olof Kylander, then do that. There's pretty good coverage of this use of channels. And of course you can look at the many PS tutorials on this topic.

[Gimp-developer] heads up for 2.6.6
Hi, I'd like to do a 2.6.6 release pretty soon now. We need to get this release out to be compatible with the upcoming GTK+ 2.16 release. So if you have patches pending that address bugs on the GIMP 2.6 milestone, or updated translations, please make sure that they are committed in time.

I can't find any references on using gimp channels for spot colour, in fact google only finds me claims that a weakness of gimp is that it does NOT support spot colours. GIMP does offer spot channels, but there is no (easy) way to output the spot channels directly to a printer in grayscale. Nor does the channel mixer operate on the spot channels. I use spot channels to create separations for printing. Each spot channel corresponds to a positive that will be used to create a screen (plus one channel to represent the substrate). In PS, one can turn off the RGB channel and use the visibility of the spot channels to simulate the final output on the printing press. Turning off everything except one spot channel renders that spot channel in grayscale (which makes printing the single channel very easy). Turning on two or more spot channels renders them in RGB. This is incredibly useful when setting up multicolor prints (think of a white underbase for printing a bright color on a dark substrate). I can work around most of these things in GIMP by doing things like reloading the channel as a selection, creating a new layer and filling it with black and printing just that layer - but it can be quite cumbersome. Also, PS supplies a very badly-named function called Apply Image that allows you to take the contents of any given channel and apply it to the contents of any other channel using the available blending modes (multiply, screen, etc.). This is the real power behind channels. 99% of people will likely not need spot channels, but to the reaming 1% they are quite useful. Hopefully with the coming of GEGL it will become easier to do some of this pre-press separation and channel mixing.
