GIMP :: Select Certain Portion Of Color To Be Removed
Sep 24, 2012
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.

When dealing with blocks, in this instance. If I select the entire object, I get one type of color in the layer pull down. If I select a portion of the object, I get a different color-what is going on? Is there a switch or something that I am missing?

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.

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 ?

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 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:Â Â Â
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 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'm trying to select a portion of a path by using the direct selection tool and shift clicking on the anchor points. But when I click and drag the brush over onto the path, the brush stroke is applied to the entire path..... which I dont want to happen. I only want it applied to the section of the path.

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?

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.

Yesterday, before I got the problem, I got the toolbox AND the other toolbox, on the left and right, excactly as how I got it in the first time I got GIMP. But the next day, all I see was a blank screen on the GIMP, I check the "Windows" menu, go to the "Recently closed docks" and said "empty", it got erased completely on the tool only. The grid level, my other files, ect. is there, but the toolbox is completely erased for no reason.

I've been using GIMP to make GIFS for a long time now, but recently the "optimize for difference" option I've used is having the reverse effect it should have- ie, it's making the file larger. Here's an example. It's the exact same image, same dimensions, same amount of colors. The first one is unoptimized, each frame is a full picture, and it's file size it ~149kb. The second one is the same as the first, except optimized with about ~50% of the pixels removed from each frame (except the first frame obviously), and yet it's file size is ~155kb. I can not for the life of me figure out why an image with most of it's pixels removed is creating a larger file size. [URL]...

I have a large background image and I want to change (lower) the transparency of the header portion. I can select the portion with the rectangle, but after that I'm stuck. I tried changing opacity but it affected the entire image. I tried selecting Layer -> transparency -> add alpha channel, but that didn't do anything that I could see. How do I make the rectangle portion that I selected somewhat blurry?
Note: I did simply blur out the header portion of my image as one solution. But is it possible to add a layer over just the header part of the image and make that layer semi transparent?

Is there an option to move just a portion of a layer (with the Move, Scale, or Rotate tools, for example) without having to first copy the portion, then delete it, and then paste it as a whole new layer?
For instance, if you have a picture of a house and there's a tree off to the side, and you want to shrink the tree a bit so the house looks bigger. Currently, I would ( a ) copy the tree, ( b ) delete that selection, and ( c ) paste the tree as a new layer....and then finally (d) shrink that.
But could I simply select the tree and shrink it on the same layer?

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'm trying to make the blue bottom portion of this wall match the top off-white portion. I try to paint over the blue with the color replacement tool, having set my brush to match the top wall, but when it overpaints the blue, I'm getting a much darker gray that doesn't match.

I have a nice image that has lost the red channel histogram data for about half of the image. It can still be viewed, and the preview is correct.
Can I copy the histogram data from the red channel of the non-corrupt portion of the image? I know it's the red channel because when I open the color data from the corrupted portion the red channel is literally non-existant.

I have two questions for CS4, which may not be possible, and I didn't find in the feature forums.Â
Â
1) Is there a way to do a color range selection created from all the colors that were selected from the magic wand tool. See attached image one.
Â
2) Is there a way to crop an image based on histogram? For example if I wanted to remove all px that were above level 200 for all colors (or a specific color). Can effect the image at all from the histogram (without an side step to something like select color range)?
Â
I'm working with very large images on multiple systems (both 32 and 64 bit, all CS4). Normally in the 50,000x30,000 -- 50,000x70,000 px range. For the sake of argument and ease of use I could scale down but eventually need to be operating in this range. The images are created by stitching a series of images taken under high magnification. I would like to find ways to quantify certain regions of interested based on color, but that do not have great color separation (see image 1). The hope would be take this information from several images and export the histogram information. As far as cropping the histogram is concerned: the scanning process used to create the stitched images produces a lot of near white color variation that so far I've been unable to select entirely (via color range select using clusters). I would say my best effort is only 85% of the "white" (see image 2) I want to drop out the white px for size reduction and noise reduction when it comes to histogram statistics.
Â
Also I know this is pushing the limits of intention for PS, but we tried this on three other software packages-seemingly designed for these purposes--and failed.
