Re: [Gimp-user] Removing a layer (part of jpg) from graphic.

And it can sometimes take a while (see Re: how to invert greyscale values only... (Rich Evans)) depending on the complexity of the subject. Anyway, your question says layer, and i'm surprised since jpgs don't handle layers. pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] how to invert greyscale values only...
"Duplicate layer, invert bottom layer and cut all blacks and whites out of (transparent) top layer (of course, if there's a range of greys it gets more complicated)." it's evident that this is the problem : i don't know about Rich's photo but the sample i use here have various flavors of blacks'. If it is not a simple Color2alpha should work to delete blacks and just add a white layer below :) i guess this is not the case :) Rich : Try Gmic Toolbox>Colors>Replace color select black as original and white as dest and play with smoothness. Is that good ? !! It's not working exactly the same as Gimp's replace color!! find gmic here : http://gmic.sourceforge.net/ this is a external filter addons with so many possibilities :) pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] how to invert greyscale values only...
not completely satisfied with sven's method, working on some pictures but not any, depending on the shades. I used to do it in CMYK a long time ago with photoshop by just pushing the image to CMYK and inverting the K curve. I guess something might be done with decompose color filter or so. But the quicker/best average i've found is just adding a mask based on the layer (L from Lab or N form CMYK could be used too), and play with the curve to adapt to the shades+refine with brush on mask. It takes few seconds if the picture is not too complex. Then put a white layer below and it's quite done. But i'm not completely satisfied with it. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Hue GUI
lo I've just seen this screenshot of a forthcoming new node in blender and i find this rainbow UI really nice because it lets you quite easily (gimp curve-like) modify any hue of the document.

Re: [Gimp-user] GIMP vs Photoshop
I don't remember how this discussion has turned to a GUI discussion just as if the hugest difference wetween the two was this point. Anyway, Gimp is great, and photoshop has many default too. It also tries to implement new GUI possibilities, but they sometimes shouldn't, i guess :) "Most people thinks having two different menubars in one application is insane. The small amount of people that thinks it is a good idea will have to maintain code for that themselves, sorry." One thing that might be interesting is having contextual menu which is really contextual to image areas we're on, instead of a simple duplicate of main menu. WOuldn't be a second menu, but just an extract of immediate main applicable functionnalities. pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Re : GIMP vs Photoshop
This is a common question. The question is not what a software does, but what you really need. Then you'll find the software by testing it for a long time (i'm not sure photoshop 30 days is enough) IMO Photoshop doesn't really supports 16bit and CMYK just because when you switch to these modes, a huge amount of functionnalities are made unavailable. The workflow is working in RGB as long as possible then export. RAW pictures can have higher bit-depth but you can use ufraw (gimp-plugin) or rawstudio (simple), digikam (use too) to manage this. IMO too, Photoshop doesn't really handles RAW, which is the job of Camera raw (in fact using the dcraw library like digikam and ufraw) or Lightroom in adobe's product. If you just begin, try gimp and if it doesn't match, you can try photoshop later. Any knowledge you'd have get in Gimp will still true in photoshop. Personnaly i used to be a photshop teacher and i switch completely a long time ago, but you're not me. Mainly Proprietray ecosystem try to phagocytate many applications ... Free ecosystem is working with more specialised tools (qtpfsgui, hugin, digikam) which complete the workflow). pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Re : gimp brushes from abr ?
Just put the .abr file in your $HOME/.gimp-2.6/brushes. Relaunch gimp and it might be OK. Unfortunately, i feel that Gimp is running much slower when such brush set are loaded. It seems to me that gimp loads them all at launch time. Is there any caching that would allow to have them available but not loaded full-res until we need them ? pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] Native Support for SVG
It seems that my message has been sent several time. I don't know where it comes from, please apologize for this. actual i don't have any idea of how vector layers have been implemented to Gimp. I guess the most important thing is not that vector property of the layer. IMO, having vector masks (whose mask would be linked to a path) would already be a very good improvement. pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
Re: [Gimp-user] Native Support for SVG
There is no non-sense that Inkscape supports some bitmap operations and also no nonsense that a bitmap applications support some vector possibilities simply because in many project, you simply need to mix vector and bitmap datas. a logo on a photo for example : and if the logo can be kept vector that's much better. if the photo don't need any modification, yo ucan simply load it into Inkscape (except that inkscape doesn't deal with import resolution), but in the other case, it will be more comfortable to open the vector logo in Gimp. Anyway, gimp works on vector layers since a long time and it's on a good way. SVG import has been improved in the last realease and will go on. Just a question : text tool is a vector tool. Would you tell gimp don't need it ? pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Tinting brushes
I'm searching for a way to tint a phot-based brushes. What i found using Gradient option of any brush tool is that the color of the gradient are filling the shape of the active brush shape. What i'm looking for is something that would replace the brushes values by a color. Just as if you were modifying tint from the color menu, but this directly in the brush tools. pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
