Re: [Gimp-user] Enhancement request: Transparency as a "paintable" color - Update
Just to be clear - the reason I am proposing the enhancement request is a new way of using a feature which has already been coded (ie giving the paintbrush eraser functionality). The purpose is primarily to have a better workflow, but also to have more meaningful treatment of "background color" for pictures which have multiple layers (and an alpha channel). I have reposted the sample picture here: http://brendanlearnstosee.wordpress.com/2013/07/26/ecorche-dorsal/ The xcf has been renamed with a .jpg extension otherwise it wouldn't upload. By way of example in relation to the paint-with-background-color trick: "*also a friend of mine commented that using white to erase was a good trick, but in Wesnoth it's actually really bad considering all portraits are on a transparent layer..." (From Wesnoth art forums: http://forums.wesnoth.org/viewtopic.php?f=23&t=38935 There are other examples floating around the web.) Wesnoth portrait art would be an example where this enhancement could be used. ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list

OK, Have a look at; http://docs.gimp.org/2.8/en/gimp-pimping.html#gimp-prefs-color-management Do you have color management activated in the preferences? Do you have a monitor profile? $ exiftool _DSF2455.JPG |grep Intero Interoperability Index : R03 - DCF option file (Adobe RGB) Interoperability Version: 0100 There should be many .icc files in /use/share/color/icc I occasionally get an image sent to me with an embedded profile, gimp asks me if sRGB will do to replace it. Anyway, that's about the end of my knowledge. -- Owen ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list

You could always just use the Eraser tool. I'm pretty sure you can set how strong it is, the brush style, etc. Sent from my iPod On Jul 25, 2013, at 9:09 AM, Brendan Scott wrote: > Hi All, > > I have lodged a request for GIMP to support use of transparency as a color. > By this I mean mainly that when using a paint tool, painting with that tool > paints only the chosen level of transparency.

Re: [Gimp-user] Enhancement request: Transparency as a "paintable" color
Hi Brendan, does the 'Color Erase' painting mode in the Paint tools dialog solve your problem? See http://docs.gimp.org/en/gimp-tools-paint.html#idp11582648 It erases parts of the layer that are painted in the foreground color. To achieve partial transparency use the Opacity slider. Note that you have to right click on that particular layer before and select 'Add Alpha Channel' from the context menu.

[Gimp-user] Enhancement request: Transparency as a "paintable" color
Hi All, I have lodged a request for GIMP to support use of transparency as a color. By this I mean mainly that when using a paint tool, painting with that tool paints only the chosen level of transparency. The enhancement request is here: https://bugzilla.gnome.org/show_bug.cgi?id=704775 This email is to invite comments on the proposed enhancement. What? Ability to tap a palette region with the paintbrush and then "paint" with full transparency/erase. Why? This request occurred to me after watching online digital painting tutorials from a couple of different sources. In them, the artist chooses a particular color as their background (typically white) and, rather than erasing their mistakes, simply switches to the background color and paints over with it. I have seen several comments on these videos (replicated across the sources) to the effect that this swapping to background color rather than using the eraser is a neat trick - mainly because it simplifies the workflow. How would I use it? I recently worked on an ecorche http://brendanlearnstosee.deviantart.com/art/An-onion-skinnable-ecorche-dorsal-view-387530797 To do this I basically had 9 tool presets - a solid brush, no dynamics in each of 3 sizes (small, medium, large) - the same brushes but with pressure->opacity dynamics; and - erasers in each of the three sizes (with no dynamics) I also had a small palette of colors. The tool preset tab separates the brushes from the erasers. So each time I swap from paint to erase and back again I spend a little time hunting, and breaking my concentration. I have a Wacom tablet and the pen had an eraser on the other end from the stylus. If I spin the pen around, it gives me an eraser with the right size and dynamics. However: - the palm rejection on the tablet often skips while the pen is being spun in my hand, so I can end up in a changed window, screen or activity (I am on Linux); and - the GIMP's interface doesn't seem as responsive to the eraser as to the stylus. I was specifically creating an onion-skinnable picture, so there had to be multiple layers and each layer had to have transparency so I couldn't simply use a background color. Any time that there are multiple overlapping layers a transparency brush will be useful. Implementation I don't know how it would be implemented or whether transparent should be treated as a color internally. The main point is that the workflow would be simplified if fully transparent were accessible through the color selection interface. If I could add fully transparent as a color to a custom palette, then I could have my "eraser" and color selection in the same place. I know that conceptually it may be useful to draw a distinction between an eraser and a paintbrush but, in practise erasure is equivalent to painting with transparency. Also, having transparent as a color is more consistent as the background "color" for layers. I thinking only of a fully transparent brush, simply because that would be my use case. There would probably also be a use case for partial levels of transparency (this is already sort of implemented through eraser opacity).
