GIMP :: How To Extract Colors From Image
May 26, 2012
I am doing a head start in GIMP. That means i am pretty new to GIMP. I have a bunch of tasks to do.
At the moment - i have a special task. i have a image that has got some arrows - i want to extract the colors (that are the exact colors of all the arrows.) After this i want to draw in a new image a bunch of balls - exactly with these colors. Is this doable!?
´
Question: how do i do extract the exact colors - can i get the exact color scheme - some hexa-code or how would you do that!?

How I extract a reasonably dark image from its background? Below are two identical images with white background.
But the preset color of my vistaprint business card is light blue. So I just want to paste the image from the links below onto a light blue business card if that is possible.

[URL]........
This is almost 100% what I want: [URL].......
but for some reason the resolution from this home made job comes out terrible at Vista Print so I have to do the card writing on their site and give them a better resolution image which the one in the first two links is.

I am attempting to create screenshots from an old video game and one part of the game includes a semi-transparent overlay layer that I would like to extract into its own image. I am able to render each layer separately in the emulator I'm using, but the screenshot tool is only able to export the final rendered image, so the transparent layer, when rendered alone, still results in a screenshot where it has been merged with the game palette's background color. I have managed to get 2 different copies of the overlay image using 2 different background colors, but I don't know the transparency percentage on the overlay. Is it possible to extract the original semi-transparent overlay with its original colors and transparency levels knowing the original background color? I can get more screenshots with different background colors if that would work. Also, the overlay only has a 5-color palette, so it's not a terribly complex image. I'm attaching the images I have with the background colors included as separate layers in each.

Is there a way to view all the colors in an image at once in GIMP? If not is there a place I can suggest it?

I'm designing a banner for my gaming guild's forums. I have draw the logo/banner and textured it. After Desaturating the image im left with a nice B&W image.
I know of many ways to color the image but everytime that I do the color doesn't match the other colors we have on the forums.
What I want to do is color the image according to a color gradient that we use on the forums.
I would like to have the whitest pixels of the banner be the lightest color from the gradient(#c0a864) and the darkest pixels of the banner be the darkest color from the gradient(#917341). And have GIMP interpolate between those two colors for the other pixels in between the lighest/darkest.
Similar to how a Bumpmap works, only instead of simulating depth based on the range of colors from Black to White, I want it to colorize the banner.

is there a way to take an image opened in Gimp and display the palette of colors in the image or convert the image itself into a palette of colors that are in the image?

Situation Basically I have a series of 8-bit bitmap images which all use different palettes but have around 64 colors in common.
This will allow them to be combined with another graphic which uses only those 64 colors in a 3D engine, thereby allowing that graphic to be used with the images with no color misassignments.
I need to be able to set those 64 colors to the same position in the colormap for each image. I could just limit the images to 192 colors, but the loss of information is unacceptable to me.
The task I'd like to manually drag those specific colors to the bottom of the colormap in a set order, but the "Rearrange Colormap" dialogue does not show me what their RGB values are, so there is too much room for error. (Tried in Gimp-2.6 and 2.8)

Any way to change what colors make up an image. I have a palette of 400+ colors that I'd like the image to be composed of but I can't find a way to convert it to only use those colors. Changing the mode to indexed mode doesn't work since you can only index 256 max colors.
Is there any plug-ins or tools I am missing that can do this? (Basically it will change every pixel in the image to the closest matching pixel from a large [400+ color] palette.

I want to create a theme for a nokia phone with a 65000 color display. I cannot find a way to limit the images to 65000 colors. The maximum amount I can select is 256 by converting the image to an indexed display.

So I am creating this website, and my customer wants a header banner similar to this:
(I don't know if it's clear enough, but there are multiple lines going through the image, with different gradient colors and so on)
Now I can't use this image, since it belongs to another website, but I want to make my own. So, I have no clue about how to make these lines in GIMP. I know GIMP's interface very well (been cropping, coloring for years), but not advanced features like this.
And it's not only the lines, but also the shadowing/coloring in between the lines that I seriously have no clue about how to make.
What is the tool called used for making this? Is there a video tutorial on how to make something similar?

i play around with a gimp-image. i want to "ERASE" the text in the balls.
Well i guess that this is a bit tricky - since the background of the circles/balls is somewhat different and has sometimes multiple "(!!!) background-colors. So if we try to get the original - color of the circles then this is somewhat tricky.

I am working on tiny comic-strip frames that are being drawn as seperate images and when it comes to colouring, there is a time-consuming snag where I forget the exact colours of the finished frames which I need to keep checking and seeing earlier single images in order to compare and then reproduce the colours accurately in a consistent sequence.
Believe it or not, I get around this problem by taking digital still camera shots direct off the screen and consulting them afterwards! This does work, but it's hardly practical------is there an easier way to repeat the exact same colors on a separate image, without having to constantly refer to pre-existing images within GIMP? If I can reproduce the exact colours on different images automatically without having to recheck earlier images, this would save me a lot of time!
[Ideally, does every shade of colour have a code number or similar method I can enter and it will come up again accurately? This way, I could write down the shade number and repeat it exactly later on a new image where the exact same colour is required.]
The sheer number of shades of colour and tones make it very difficult to remember the exact colours accurately.

I have been trying (without much success) to figure out a way to change all non-white color elements on a picture to a single set color, and was wondering if that is possible to do in GIMP.
For example, I'd like to turn something like this tri-color Italian flag. To this, where the blue color is a color of my choosing.

I created a new palette in gimp using my original RGB image (containing shades of yellow and black) which gave me about ~200 colors (with interval=2 in Import dialog). Then I changed the mode from RGB to Indexed using the palette I created above, but the resulting image contains only 2 colors - black and yellow. All the dark-greys, light-greys and different yellows are absent.
I want my indexed image to resemble the RGB as much as possible but the result looks disastrous.

So I am trying to work with a web page template in dreamweaver. I am attempting to open the background image in this template with gimp, then paste over top of the Original image with a new image. Every time I paste the new image in it takes the color style of the original.
I.E. The original image is in shades of brown while the new image is in many different colors. Whenever I paste the new image (the image with many colors) it changes to shades of brown like the original image.
The same thing happens if I open the new image as a new layer or just simply copy and paste the new image in.
How do I bring the new image in without it changing colors?

I have two layers: a background in yellow and a cropped image in the other layer. Now I want to dissolve the cropped image in the background, how can i do that automatically? I know I have the smudge tool, but the results are not so good for me...

I'm using gimp 2.6 on ubuntu. i have some pictures i would like to enhance.
There's that image image 1
and i would like to make it look like image 2
As you can see the second image uses only about 7 or 8 different colors and the outer lines are nice and smooth not stuttering.
Is there a way how i can change the first image to something like the second one, maybe something like replace 10 different colors which are similar to each other with only 1?
I tried and played with the options (bucketfill, posterise, or the cartoon option from artistic menu, increase contrast, brightness etc...
Is there an option to smoth the outer lines etc? i just want the dog, the rest of the background is not so important.

I've been playing around with the gradient map tool, and love the randomize and noise option to give me nice looking gradients for my images.... my question is, is there a way to "extract" or "split" the colors of the randomized map into its separate colors as if I was creating them manually with the "solid" option?

i have been doing HTML off and on for a few years but am really starting to get really heavy into it, as well as CSS and other tools...and have just discovered GIMP
i have an image..which happens to be my business card and to begin with, it was an .eps file, but i converted it to a .jpg...what i am wanting to figure out, and do with it is use it for my web page i am building
it has a background on it and on top of it it has my text...i am wanting to keep the text also, but my main concern is to use just the background for my website....how is extracting the back ground away from the text possible in GIMP and also saving the text as well.

I am trying to take a jpg file of an image, and write each RGB pixel color's value into a 3 component integer vector corresponding to the RGB components of the color for that pixel. For each pixel in the jpg, I wish to write the corresponding 3 by 1 integer vector into a matrix after which I plan to do a SVD decomposition of the newly constructed matrix to do an image analysis.
Any plug-in that allows one to efficiently iterate through each pixel in a jpg, and convert the pixel data to a RGB integer vector, and say write to a file?
Specific Details: I am using gimp 2.6 as my image editor, and wish to collect all the RGB 3 by 1 integer vectors (where each 3 by 1 integer vector corresponds to RGB color of exactly one pixel in the jpg image) into a matrix of integer so that I can do a reduced SVD decomposition of that matrix to analyse the pixel data: I wish to compare two similar images by using the SVD decomposition of integer matrices corresponding to the two images saved as jpg files pic1.jpg and pic2.jpg.

I'm new to GIMP and I'd like to know how to cut out or extract an object from it's background.
There's a fest being held at my college and I've been assigned to cut out the logo from the posters of the previous year (I've attatched a copy of it below). I've tried using the cut tool, the lasso and also the foreground selection tool. The cut tool and the lasso tool didn't work as the object is quite complicated whilst the foreground selection tool happens to coat the logo instead of the background. I've tried invert and it doesn't work. Is there any other way to extract the logo?

So I was making some pics less blurry using a method invloving grain extract, and in one pic I forgot a step and saved it in its grain extract mode. Is there any way to change the picture back into its original? It's too late to just press undo since I already closed GIMP.

Have to deepatch (cut out) a horse from this pic, but it's hairs are everywhere. Also, the background doesn't differ much.
Tried through channels, even quick mask pro 4.1, really run out of ideas, you tube can't help, no photoshop users that I asked can help. Can you, please?
Attached file is too small for you to see the details, don't know how to upload bigger image.

Attached is a .JPG I would like to modify. I have many drawing like this one that we would like to make into a catalogue.
I would like to make all theses doors the same image size with the a square transparent background.
I have figured out how to remove the background however when I try to adjust my image size it is still adjusting my canvas size.
What I have been trying to do is have a transparent background layer with the door image on a separate layer but I'm not having any luck.
I'm new to PS so my knowledge is limited. I'm using the CS4 extended version.

In Photofiltre, it's dead easy to extract the gray tones from an image to boost up the colours. It's often better than just increasing saturation or so.
But since I have Photoshop CS3 I'd like to do it there. It must be possible to do something like that too. But how?? I just can't find the right way?

I know this is a simple task if you understand masks better than I do but I normally slave away with max zoom and an eraser until I get the image extracted the way it looks good. Unfortunately for this image its going to be blown up and when I look at it the girl appears like she has been eaten around on all edges by termites.
