GIMP :: Photographic Image - Select By Color Refinement
Oct 22, 2011
I have a photographic image, I need transparent background. So normal add alpha channel, select by color, clear, save as png.
But this time, select by color also selects parts of the image I do not wish to clear, including the models eyes. Set the threshhold to zero and it *still* selects parts of the image.
The image is already isolated from background. I tried using paint bucket to change background color and select by color that way, and it sort of works except paint bucket doesn't fill in parts where the models curly hair cut the path, so I end up with transparency but white background parts in her hair.
What would be cool is if I could select by color, and then manually use some tool to deselect the selected parts on the model that I do not want to clear, but I can't figure out how to do that.

I want to select a specific color from within the image, and change all similar colors within that image to a different color. In other words, after using the Color Picker Tool to select a color from the image, I want to take the selected color (and everything in the image that is equal to or similar in color), and change them all to a different color.
I tried using the Path's Tool to create an outline in the image, and changing colors that way, but it changes all the other colors in the selection I don't want to change. I just want to change all colors in the image/selection that are equal to or similar to the selected color. How do I do this?

Is there a way to make the color select tool not only select a specific color but related shades as well. I have a graphic that is mainly shades of gray but with black outlines and divisions as well as other colors mixed in. I want to shift all the shades of gray to shades of dark yellow without have to select each shade individually.

When I use the bucket tool to fill in an area, how can I select a color? It just uses black by default and I can't find a way to change this.

How I can use gimp to select all shades of one color, and change them. I was using the colorize tool, but because of all the shades in the image, it doesn't seem to be working correctly, or I can't find a good way to change the colors. Perhaps a brief explanation on how to recolor an image would be amazing, or perhaps a better way to use the colorize tool in general.

I already know about the Select-->By Color and then Edit-->Clear method of removing all of a certain color from an image. The thing I was wondering was what would be the best method in Gimp to select only certain portions of a certain color in an image and have them cleared out, not all of that color.
I attached an image to this post. In that image, I want to only remove the white background, not the white in the eyes of the white in the hands.

I was using Paint.net but I've found it too limited. The GIMP has much more power and I can do a lot more with it, but I've found a few things I can't figure out how to do.
For example, when I use the Eyedropper tool () to choose a color, GIMP doesn't seem to include any transparency in the selection:
The Colorpicker just chooses the color at 100% opacity. Is there any way to change this so that my new foreground color includes the transparency level?

I'm looking at tutorials on how to add strokes to text (I downloaded it today) and they say to use the color select tool. In their demonstration, when they select text, it has the normal dotted lines around it. For me, when I click it just has a thick border around it and it tells me to move my mouse to change the threshold. It won't select the text, just change the threshold when moving my mouse from left to right.

I am currently searching the tools that I use in Adobe PS/AI in other products. I have recently downloaded GIMP as a possible substitution for Adobe PS/AI. But I have been searching the default (no plugin) tool box for anything that can do the Magic Wand Tools job. I just have not found it.
Magic Wand - select a pixel/color on the screen. Magic wand will then select all colors that correlate to your selection. I use the magic wand to kill backgrounds out of photos.

I have an image that is just a rounded corner and I need the color changed. The image is red and the background white all on one layer. Is there a way to only select the red area? This way I can brush it with a different color.

what I want to do is select a shape out of an image and I want everything inside it too. For example it would only select the green outline of the shape, is there a way to also take what is inside it, or delete everything around it?

I'm brand new to GIMP, I just downloaded it to get into some simple pixel art.
I was going fine, but I've run into a problem. I'm trying to select a portion of my image using the rectangle tool, and then move it to a different location using the move tool. However, when clicking and dragging the move tool it shifts the entire image, not just the portion I have selected. I read in the FAQ that you need to press "Enter" to finalise the selection before you move it, but even doing that doesn't work.
This was working fine for me earlier, I'm not sure what I've done to break it. I've tried resetting my tool preferences back to defaults but that has not worked.

Is it possible to select a part of an Image on the background layer. And when you delete it, its removed from the rest of the layers as well.
Because I'm working with a DDS image and it has mipmaps (smaller and smaller copies of the background made as seperate layers.)

I've tried using GIMP many times, yet I've accomplished very little, given all of GIMP's functionality. For example:
If I want to select part of an image and copy it to another area or to a new image/layer, and also FEATHER the edges, here's how I'd do it in an old graphics app I often used years ago:
1. Select the area.2. Hold Ctrl while moving selection with Move tool.3. Use the slider to soften the edges to my liking.4. Press Enter to anchor selection. Done.
And there were sliders also for opacity and other things. So very SIMPLE because the prog. was designed very intuitively. How would I accomplish the same in GIMP? Well, most of the time, I WOULD ACCOMPLISH NOTHING! At best, I'd enter values into the box, not like the result, enter new values, repeat. And that's on a good day.
Somebody write a SCRIPT/PLUGIN that allows the use of sliders exactly as described above! I desperately want to be a HAPPY GIMP user, but I'm growing ever more hopeless. I don't want to turn on my older PC just to use a graphics app that actually lets me get things done.

1. Select a portion and copy.
2. Create new layer.
3. Select the new layer.

I've been wondering how do you get the rectangle select tool to move the image, like in mspaint whenever I use it, it just moves the rectangle square and not the selected part of the image.

I'm attempting to tilt this image for use in a game im writing. I've been using Map Object and rotation (Y) but this then causes pixel color changes on the boundary with the background color. How would I tilt this picture without getting the problem?

When I copy a selection from one image to another, I can't select the feather tool to blend it in the new image (it's greyed out). I have to first anchor the layer, then use the paths tool to re-select the pasted portion again, then feather. Is there another way?
Update: Looks like I can feather before copying/pasting the selection.

I'd like to be to select a layer groups and copy them over to another pre-existing image.
I've been struggling with this for an hour or so, and I haven't found a way to do this.
Is is possible to do this in GIMP?
The closet I've found is a kind of paste where you do this: drag the tab of the origin image over to the tab of the target image. The result is a new layer in the target image called "dropped buffer". However, the entire origin image is imported flattened.
I've been trying other drag and drop operations, but without success. Usually when I drop the selection to the target image, the icon under the mouse dissapears, and nothing actually happens.
I thought this might be a window manager problem. But I get the same results across kde, gnome and xfce.

I need to get the visible portion of a particular layer in the final image.Lets say i have 4 layers and some portion of each layer is visible in the flattened image i would like to get the portion from each of the layers. The input will be in xcvf format.I will ideally want to automate this and output to file in some format looking like this,
Layer1 ---> Co-ordinates of visible polygon from this particular layer in the image .
Layer2 ---> And so on.
How to proceed with the script. I think brute force is to take each non-transparent pixel and and find the same pixel in all above layers if it is not found it will be added to the region.Or something exists like selection from alpha combined with multiple layers ?
Or if there is a way to find out for an image with all layers visible which pixel came from which layer ?

there's nothing in that dropdown menu for you to select your source image/layer in the Move Path plugin.I am using an XCF (Gimp) file, with many layers. I selected a particular layer, then I opened the Move Path plugin.

Okay so I'm trying to take the white background off of a picture using the select a color on white, but it takes out a lot or the fur and eyes(it's a picture of a cartoon cat) How can I remove the areas of can from the selection without removing the pieces of cat too.
It's creative commons, so I guess I can post screen shots...
The cat is from [URL]...
A general idea of the selected area
What happens when I take out the selected area
So how can I take the pieces of the cat out of the selected area so when I try to delete the background I don't get an invisible cat?

I have a simple silhouette design that I spent a long time creating and cropping out. I made it one solid color so after I saved it I could use it as a layer and change the color with the bucket fill tool. When I saved it, then opened it up again it appears one color until you zoom in, where it shows it is actually a number of different shades of that one color which makes it very hard to change the color of the image. How to do this so I can save this layer and change the color of it easily? It is going to be part of a logo I am doing and do not yet know the color scheme.

I have an image and all I want to do is change it to a different color. So if the image is mostly red, I want to shade it blue but still keep its quality, meaning the light-red pixels will turn light-blue, and the dark-red pixels will turn dark-blue.
I prefer an option that automatically changes all the colors for the entire image, but if there is a shader tool where I have to manually shade the image, that'll work too.
I input the image, then I went to Image > Mode > RGB, and from there I went to Colors > Colorize and used the sliders to change the image to the color I want.

I discovered GIMP 2 days ago and I am pretty excited to get started with it. The only problem is that I am a total newbie. I would really like to change the color of this image from black to blue but how to do so and the tutorials that I have found online don't really apply to what I am trying to accomplish.
