[Gimp-user] GIMP and a SMARTBoard?
My department just got itself a SMARTBoard: http://en.wikipedia.org/wiki/SMARTBoard I'm curious - has anyone here tried out a SMARTBoard with GIMP before? Would GIMP recognize the different pens or the eraser? - Jürgen Hubert Art Tutorials Wiki: http://artwiki.wikidot.com/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Lines in the direction of a gradient
Here's something tricky: Imagine if you have a gradient between two colors (such as black and white) - a smooth, gradual change between the colors. This gradient might take any form, but the main thing is that the change between the colors is smooth, instead of aprupt. Now, it is fairly easy to greate height lines along lines with an equal intermediate color between the two extremes thanks to the Posterize function. However, I am wondering if there's any way - a script or something else - that makes it possible to generate lines that curve from one extreme to the other? This image of a visualization of a magnetic field might help understand what I am looking after: http://en.wikipedia.org/wiki/Image:Magnet0873.png Imagine, for example, the North pole of the magnet representing black, the South pole representing white, and the regions between and around them representing a gradual change from one color to another. This script would take this basic color gradient and then change it into something like this image. Does any script like this exist? - Jürgen Hubert Art Tutorials Wiki: http://artwiki.wikidot.com Science Jokes Wiki: http://science-jokes.wikidot.com/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] What have you done with Custom Brushes?
Here's something I am curious: What have you done with custom brushes? I don't mean the technical details on how to create them - I know most of the details (and can probably figure out the parts I don't know). Rather, I am wondering what you have used custom brushes _for_. In what kind of situations have you felt that the standard brushes of GIMP were insufficient? What kinds of effects have you created when painting with custom brushes? And how often do you use such brushes? - Jürgen Hubert The Art Tutorials Wiki: http://artwiki.wikidot.com/ Gallery: http://jhubert.deviantart.com/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Digital Watercolor effect in GIMP?
When reading about Corel Painter, I've frequently come across a so-called Digital Watercolor effect, which apparently simulates how wet paint behaves when you apply color to a canvas - the virtual pigments are gradually diffused across the surface of the paper and then absorbed into it over time. This sounded pretty fascinating, and I was wondering if anyone has attempted to create the same effect with GIMP. Or would it require too radical a rewrite of the code? After all, currently GIMP assumes that it doesn't matter _when_ you make a certain stroke with the virtual pen; it doesn't matter if you do a certain stroke two seconds or two minutes after the previous one - the result will be the same. But to implement such an effect, some kind of time-sensitive mechanism would have to be included - or at least, that's my impression from reading about it... - Jürgen Hubert The Art Tutorials Wiki - catering to everything an artists needs to know! http://artwiki.wikidot.com ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Re: [Gimp-user] Blur and Transparency
Well, the issue is moot now - I've installed the latest version of both GIMP and GTK, and blurring works just fine, now. And as an additional bonus, the problem I had with my Intuos was solved as well... I guess I should update more often. ;) - Jürgen Hubert Art Tutorials Wiki: http://artwiki.wikidot.com Free Portraits: http://juergen.the-huberts.net/1hp/main.php ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

That's not what I see. I started with a white background layer, added a transparent layer, created a circular selection, filled it with white, deselected the area, and used Gaussian blurring with a radius of 20. It behaved as it should, spreading out the pixels and gradually blending them to the transparent areas of the layer without affecting the color. The only way it becomes visible is if I toggle the visibility of the background layer. Strange. But admittedly I don't have the latest version of GIMP installed on this computer.

[Gimp-user] Blur and Transparency
A minor annoyance I had to deal with is when I am attempting to use blur effects on layers with transparent areas - instead of assuming that the transparent areas have no color worth blurring at all, GIMP seems to assume that they are black for the purpose of the blurring algorithm - which can cause some rather ugly side effects. To see what I am talking about, start with a new image with a white background. Create a new, transparent layer, and place a pure white object on it (such as a white circle). Now apply any blur function to it. What you will see are some gray boundary areas around your white object, depending on what parameters you used for the blur effect. Now in _my_ opinion, what ideally _should_ happen is that you see nothing at all in this case - the white of the object should be a bit more spread out with a greater graduation of the object's transparency in the boundary areas, but there shouldn't be any discolorations. Is there some way to achieve this with GIMP? - Jürgen Hubert Art Tutorial Wiki: http://artwiki.wikidot.com ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] GIMP and tilt sensitivity
I've just received my new (okay, used and purchased via Ebay...) Intuos graphics tablet, and am toying around with its new features. Especially interesting is its tilt sensitivity. However, the only tool tilt sensitivity seems to have an effect on is the Ink tool. Is this accurate or am I missing something?

In theory one could also create a brush pipe that reacts to tilt but I am not sure if this really works. As far as I know no one has tried this yet and it would be very tedious, to say the least. Pity. I think a brush that changes shape and direction as you tilt the pen would be very neat... Furthermore, I've noticed that you apparently can't use the Undo function for the Ink tool. Is there a specific reason for this? If Undo doesn't work, that would be a bug. But it seems to work fine for me. I tested it again, and it seems that this only happens when I use the Ink tool with the Intuos (1) tablet (whether I use the pen tool or the Intuos mouse) - when I use my regular mouse instead, I can use the Undo function.

That is very strange as it shouldn't make any difference. Have you had a look at the Undo dialog? When I click on Undo in the Undo dialog, the dialog moves up to the previous instance - but the Ink drawing doesn't actually vanish. I've tested this some more, and it seems that this effect isn't actually limited to the Ink tool - the other drawing tools have the same effect. But I've uncovered another hint: When I use the fuzzy stroke or hard edged pixels to paint swift strokes, then I end up with a single brush image some time after the main stroke has ended: http://juergen.the-huberts.net/img/Test.jpg That last dot _can_ be reversed with Undo, but the main stroke can't. I was wondering if this effect was only limited to GIMP, so I called up Microsoft Paint (the first time I've ever done that...) - and it worked just fine there. I suspect this bug is also the reason why I can't use the color gradient tool - it shows the starting point and the end point as well as a line between the two, but the gradient isn't actually painted.

[Gimp-user] Making GIMP more newbie-friendly (Was: Gimp - not-gimpshop)

Ah, yes. One overlay I'd like to see appear is *not* a PS clone, it's an overlay that makes GIMP instantly useful to newbies, so runs things in modes and fashions they expect. So what would those be? I mean, I've used various graphics programs before, but GIMP was the only such program which I've used since I actually started with digital painting. And for the most part, it was all fairly logical and consistent - the only thing I had problems with in the beginning was how to draw circles and rectangles (but I am better now). Personally, I think the interface of GIMP works perfectly well. What's lacking is appropriate _documentation_ for what you can actually do with it - tutorials, to be specific. And here GIMP is sadly far behind Photoshop and other commercial applications. It's one thing to tell a newbie: This is the text tool, and here is how it is used. That's important, technical stuff he needs to know, but when making decisions about what software to use such dry descriptions won't make him _enthusiastic_. Now, on the other hand, if he finds a tutorial that says: Today we will show you how to make Giant Flaming Letters of Doom(TM) with GIMP! - _then_ he will feel enthusiastic. Last summer I started collecting all those hundreds of links to art tutorials which would eventually become the Art Tutorials Wiki links list. Since I was using GIMP at the time - and I still am - I tried to get GIMP tutorials first and foremost, but found few of them. On the other hand, there were plenty of first-grade tutorials for Photoshop, Painter, and other commercial programs out there. Many of them would make you go out and buy these programs - if you didn't know that you could create the same effects with GIMP with little effort. So if we want to make GIMP more newbie-friendly, I think we should let the developers continue to develop the program by adding new functions instead of spending too much time emulating other programs. The rest of us who aren't as well versed in coding can try to create tutorials that will make others enthusiastic about GIMP. I already have started to do that - I've started on a tutorial which attempts to explain how to draw fantasy maps with GIMP and Inkscape: http://artwiki.wikidot.com/digital-cartography And I've gotten some enthusiastic feedback from various people interested in doing so.

[Gimp-user] A Call for Tutorials
Hello, everyone. I have been using GIMP extensively ever since I bought a graphics tablet early last year, and although I'm not nearly as proficient with it as I'd like to be, I think I am improving nicely nonetheless. However, there is always more to learn about both GIMP and digital painting in general. For this reason, I spent a lot of time searching for good online tutorials on all sorts of aspects of digital painting relevant to me. And eventually, my link list grew so massive that I was looking for ways to organize it better. So eventually, I decided to put them all into a wiki format, and I finally found a provider of free wikis who helped me do that. You can see the result here: http://artwiki.wikidot.com/ Many of the techniques mentioned in the link lists were initially written for other software than GIMP, but they are usable for GIMP nonetheless. Others cover aspects of painting that go beyond the medium of digital art, such as drawing the anatomy of humans - but they might still be of interest to people here. But the link lists still have serious shortcomings - for example, they have next to nothing on photomanipulation, which is something I don't have much interest in at the moment, but which is very important to other people. Here I'd like to ask those of you who are interested in this topic to add any relevant links you know of - I am sure others will appreciate your help. Finally, this wiki also has enough space to host original tutorials on its own right. I've already started moving a tutorial on creating fantasy maps with GIMP and Inkscape to the wiki, and hope to port the rest over this weekend. It is my hope that others will add their own tutorials as well. Furthermore, I also want the Wiki to feature essays and explanations of various tools that can be used by artists - and GIMP certainly qualifies as such a tool. I've only created a short, bare-bones page for GIMP: http://artwiki.wikidot.com/gimp But it would be my hope that eventually people who have never heard of GIMP before could read a detailed explanation of what GIMP is, what it does and what its advantages are, as well as links to GIMP-specific tutorials and explanation of its tools. So if you could help with any of these endeavors it would be a huge help. But first and foremost I'd like to put the word out that this Wiki exists - and what, time and effort willing, it might become. - Jürgen Hubert The Art Tutorials Wiki: http://artwiki.wikidot.com/gimp Free Portraits: http://juergen.the-huberts.net/1hp/ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
