Hello,

I have a graphic in a circle and I want to have it's edge feathered in order to fit it inside mockup.
it must look as if it is not just laid over it but kind of part of mockup.

To give a better idea of what I am looking for, here is an image of a cellphone laying on the ground
where ground has sort of vignette effect. The farther it goes from center, the less it is visible:

   

I don't know whether it's vignette or blue that I need but I hope picture shows it.
I need it on a transparent background and not white since I want to integrate it
inside a mockup.

Actually vignette would make my image dark I think so maybe it's some kind of
special blur that I need?

Thanks.

Hello, this is my first post and I've been using Gimp over the years for small tasks such as creating alphas for images and exporting.

I've recently got back into tabletop gaming with games such as Castle Ravenloft, Frostgrave and Horizon Wars.  I've started on a project to essentially recreate two MB games from the early 1990s called Hero Quest and Space Crusade, and have been using MS Paint and Gimp to knock up simple grid print outs of game boards to match the sizes of miniature bases.  Sadly my 2D artskills are lacking(compared to my 3D skills and miniature painting), and although the boards I have made so far are good enough for gaming, I would really like to take it further and produce better looking board art.  I could just print the originals, but I actually enjoy doing it from scratch.

Would anyone know of any videos or books on this subject?

For some reason my png images are coming out with a black background as displayed in image provided. I simply add an image, then a layer mask. After removing the background layer, saving, and then exporting. I send the image, but it comes up with black edges whenever sending through messenger or facebook. Please help!

TWAIN problem

Hi, I've tried to open an image via TWAIN and received the following error message > Cx1magicU.dll not found. I'm fairly new to Gimp but everything else seems to be working fine. Does anyone know if this may be a problem with my installation or have I missed something in setting up TWAIN in Gimp? My TWAIN device works properly with my other imaging programs (Paintshop Pro and Photoshop, both old versions) so I don't think that can be an issue. Thanks, Dave H

A few das ago some new guy asked me about learning ressources for Gimp, and without putting much further thought into it, i said youtube.
I mean, i do search the web for all kinds of contents, but most of the time i find interesting tutorials on YT.

Now Spoongraphics posted a retrospective of 2017 on his website and reported that all his Youtube tutorials get more views compared to his written tutorial content.

167,699 : 8,779 views, to be precise. Quite a difference !

Which also explains how Nik Suporito can have over 73.000 subscribers for pretty basic Gimp and Inkscape tutorials.

Even more annoying: written tutorials take so much more time to produce, compared to a 20min video you record in one or three takes.

Hey guys! I'm new to this forum, but I've been using GIMP for various art projects for years now. 

I have a serious problem with a project, and I feel like a brainless idiot- I discovered a tutorial a couple days ago that solved my entire problem, but now I can't find the webpage anywhere, and I've forgotten the process I need to use to make this work.

See, I have a set of textures, one is a basically black and white texture for a character model, and the other is a color mask. The color mask is set up so that the game engine can color the character's texture in-game, and it has each color scheme section split into channels. 

What I need to do is use that color mask to select sections of the actual character texture, and colorize it. I'm not sure how to do this, can anyone help me figure it out?

One idea I had was to import the mask as a new layer into the model texture, select a color section, and move that selection onto the texture layer so that I can colorize it.

However, I don't know how to move a selection shape between layers. I just want to move the selection shape, not cut and paste the actual image. 

I'll link the two texture files Link to my sample images . 

Thanks!

I don't remember how or what it was. I learned this in a photography class in college and since have forgotten it. I think it was toning or maybe split toning or perhaps it was adjusting the contract but it had to do with using the eye dropper. I think the eye dropper was for finding the darkest(shadows) and lightest(highlights) areas and using that to get the perfect black and white for that particular image. I think this was done after the channel mixer with the contract tool then you used the eye dropper to get the measurements.

How do I do this in gimp? I am using gimp development version 2.9.8. Is there a tutorial somewhere?

I have been working with Gimp and other similar shareware on my relatively new Surface Pro 4. The Surface Pen I have is an older version, since the store I bought it from was out of the newest and I wanted to get started right away. Overall it has been working fine, but just in the last day it started writing funky, starting out light and gradually darkening, this happening with each new stroke. What is odd is that it is happening across platform in other programs the same way, no matter what tool/options I've selected. It's undoubtedly due to some unintentional tinkering I've done, but I don't know where to go to fix it. I used to be able to select for a solid black stroke and actually get that, but not now. It's not good when you want to define a space with a solid outline in order to fill it with a color.

Hello, my first post/question (ever) to this group. I have been using Gimp on and off for several years but am only moderately knowledgeable about it. 

Recently my tool options became detached from my tool box (probably from some tinkering on my part), and nothing I can find or do is allowing it to "dock" again, although it plainly says below the tools that I can dock it there. Dragging it there by the top tab (as I understand suggestions I found on-line) only puts it there, floating above the tools. What miniscule step(s) am I missing?

By the way, I am working with the Surface Pro 4 and the version of the Surface Pen that has the clip (would that be the Surface Pen 3?)

Perhaps it is best to watch this video first (if you haven't seen it yet) to understand what I am having an issue with.

In Gimp 2.9 I did a test with an image in 32 bit float and linear color space, although the same problem exists in 8 bit.
I start with a simple image:
   
In a new layer using the 2.9 'normal' default layer mode, painting new colors lines has this effect:
   
This is correct.  If you look around the edges of the colors, they blend correctly.
But if I paint directly in the same layer, I get the dark outlines:
   
In other words, the new layer modes work correctly, but if colors are painted on the same layer, the colors do not blend correctly.

Anyone know what I can do to fix this?  Should I download a different color space, or is this just a hard-coded flaw?
