While the colour to alpha tool is very useful to get rid of backgrounds, it also makes the image semi-transparent. Is there anything we can do ?

For eg, if we try to erase the background, it makes the image transparent. I also tried the Erase Background plugin. But it was leaving traces.

Hello, I am a novice GIMP user.  I am modifying game textures, which usually include a mask texture, with various red, green, or blue colors.  Those are used by the game engine to color specific parts of a texture to customize it.  I was manually editing parts by hand, which is not accurate, and someone showed me the short video in PS below.  I don't really understand it, but maybe someone can watch it, and can show me how to achieve the same thing in GIMP with step by step instructions?  Thanks in advance, it will save me a lot of time.

I'm sure the same effect can easily be accomplished in GIMP, and I can provide the files he is using if necessary, I just don't really have a good workflow.  Specifically, the goal is to easily, quickly, and accurately make a part of the COLOR texture (from a color or section on the MASK texture) be colored with a specific color, like with colorize or colorify, and the MASK texture to have the corresponding part be black.  I am just not getting a lot of the exact detail when I do it manually.

Hi guys, im trying to edit a number of images all at once.... the images are of faces with plain coloured backgrounds.

i have been using the batch image manipulation tool for bucket fill to change the colours of the image background .... which works great. i can do 100's at once which takes minutes....

but not i want to do the same thing, but using 2 colours and the gradient tool.

i can do this manually one at a time, step by step: 

open the image >
choose the fuzzy select tool >
click and select the background area of the image >
choose the gradient tool >
then with the gradient tool, i will select the x and y points of my gradient on to the image> 

once the gradient has successfully coloured the background i will then click to export the image, and save it as a png file in to my new folder location


sorry if this has been discussed before, 

I have added a before and after example

thanks for your time.

Hello, I am making a heightmap for the game Teardown, and I am new to complex editors like gimp entirely. 

The port (the section with uniform color) and the ground above the port, shown as a brighter red, are on different layers. I need to select the area within the port, minus the area covered by lighter shades of red. If it's helpful, the reason I need to select this particular section is because I want to add a specific shade of blue on top of this section on a new layer.
The preview isn't showing the image, so in case it doesn't work, I will also link the image below. Thanks for any help!

What I'm trying to do is overlay a stack of layers on top of another stack, keeping the order of the layers.

Something like I tried to demonstrate in the image below, where the stack of Image 02 is on top of the stack of Image 01.

I tried to use the Plug-in Interleave layers, but the interleaving between the layers occurs (alternating layers of Image 01 with those of Image 02).

I tried:
A - Export the layers of Image 02;
B - Open as layers, inside Image 01.

But in this case there is an inversion in the order of the layers of Image 02:
Instead of coming in order (from top to bottom) A00, A01, ..., A50, it comes as A50, ...,A01, A00.

I thought of using the Layer - Stack - Reverse Layer Order option, but in this case all the layers of the image are inverted and not just the layers of Image 02 (which are inverted by this process).

In short, what would be the way to obtain the result of Image 03

Thx!

Hello there! I've used GIMP for various different things over time and I've recently been thinking about how to automate some of my image processing needs. What I would like to know: is there an easy way to either get a list of all the XY coordinates of all pixels in a  particular selection or, barring that, get the XY coordinates of all the pixels on a given layer?

Everything is in the title => I'm not able to bent GIMP (I'm speaking about the "Path"   )
A picture is worth thousands words (the word GIMP is way smaller than the envelope, and "Path" is selected (NOT the envelope, anyway I tried also with the envelope selected ) )
   

tried to restart, it does nothing.

Hi
Im not a designer but our art teacher has told us that if we are interested in doing art for a job we should get GIMP. But a friend of my dad says this is bad advice and I must learn to use Illustrator.

What do you think is this true. Will I able to make the kind of things that I want to with GIMP. 

Also I think Illustrator is pretty expensive and I don't think my parents would get it for me.

Hey GIMP fam,

I need some help. Would it be possible to make everything black and white besides the butterfly? Can you please offer some suggestions or do it for me?

Thanks,

Richiie

I have been trying to put together a simple image that will end up 190mm in width using the Guides. I need to place vertical guides 10mm , 25mm, 30mm, and the next 7 at 17mm. I have tried to create a new image the exact length that would be required, and tried to add the guides. I start from the L/H side and all of the guides are measured from the L/H side except I add the additional length each one. When I check with the measuring tool, and when I look at the measurements on the bottom of the screen they are nothing like what I have put in. I have used, Pixels, and MM and CM, but I cannot get this one to work. I have looked for a Tutorial on this, but cannot find one to answer my questiions. This is not the first time this particular task has got me very frustrated. I have also tried using the measuring tool but this does not seem to help.
