GIMP :: Restrict Image To Very Limited Range Of Colours
Jul 4, 2012
I've been using GIMP for a while for basic website stuff. Very basic website stuff. I've recently been asked if GIMP has some more advanced features. Well, advanced put to my usual level of use anyway.
So, I thought I'd query if I could do the following in GIMP...
(1) Edit a BMP but ensure the file size remains the same?
The person asking is using the images for a specific purpose and they always have to be the same size.
(2) Open .pspimages and possibly save back as this format.
The answer to this seems to be no on the opening front anyway.
(3) Restrict the image to a very limited range of colours, say 3-6?
Again this is due to the very specific and restricted nature of the images they are creating.
Is there a way to automatically adjust the cut range colours (REDS) in the attached scheme such that the lighter colours denote lower cut depths in the same way that the fill range does (Greens)
I know they can be manually adjusted but when the analysis is run again the colours revert back

I use gimp to make layered stencils for spray painting...I reduce it to a couple of colours, seperate the colours into different layers and then cut them out...
When I do im left with a ghost type image where the original layer was..
I find only limited image import options under Photoshop CS5 and CS6. Under CS3, I have a number of options which I have used frequently, regarding preview, zoom, descreening, filtering, stretch, noise removal, fading, grain, etc.
None of these seem to be available under either CS5 OR CS6. In fact, under CS5, under "FILE>IMPORT", I I don't even GET the Canoscan 8400F opton. This is pretty basic stuff, getting good quality off a scanner. Do I need to go back to CS3 for everything? It actually worked.
Is there a way to change a range of colors to another. Let say I want to change a pic with different shades of red to blue. Which tool would do the trick?
I have a image that i need to convert to a set 16-color range... the range is: 209 209 209148 157 15723 19 1963 63 63155 42 38213 118 14452 72 2355 179 4481 48 26182 169 2436 48 14589 128 208122 47 188188 62 19937 109 140233 122 46
when I exercise the opacity slider for an active layer I can see the full range of opacity follow the setting. Somehow I've gotten this v2.6 on a Linux box into a mode where the visible opacity doesn't follow the slider full range. Instead it is all or nothing. At 50% or less opacity the layer is entirely transparent and at 50.1% or more it is entirely opaque.
When I have an color image I sometimes need to select a certain color from all the image. Is there a way with Photoshop CS2 to make this selection so the program figures out which areas have the same color specified and select it also? (did I explained myself?)
In other words if I want to select, say dark red in all the spots with the same color range, can I make the first selection of the color anywhere in the image and then use any selection option so it selects all similar colors?
If I open an image that I have previously created (I'm working with .gif) and then select a colour on the pallet (it can be either FG or BG) and then try to place the colour on to the image - the colour is different to what I selected on the pallet.
I have the same issue with the 'bucket fill tool' or by selecting 'edit/fill with FG color' or by selecting 'edit/fill with BG color' or by placing a selected color text onto the image. I haven't tried using any other method.
I've tried deleting and reinstalling Gimp and I'm on Win XP PRO SP3.
I have myself a picture of my kitcar which I am looking to change the colour of however I want to preview a selection of colours using GIMP to see how they look on the car.
How to "overlay" different colours on the car? I am not sure how to go about selecting just the body of the car so that I can overlay different colours.
I would prefer to not have to hand paint each colour over the body of the car.
The way I know how to do it is by typing the first word in black lets say, then open a new text dialogue on another layer and type in the other word with a different colour.
Is there an easier way to do this since I'm afraid that my text won't be in line with each other?
Best way to get the colours to be the same when I replace a face onto another face esp if you can lightly dust the colours in so the finished picture looks natural
I'm currently working on a forum template (phpBB), and I want to invert the colours of the background. I did it easily for some pictures, but I can't invert one of them.
It's a simple gif, I don't know why I can't invert it. When I go to the menu 'colours'->'invert', the option is disabled, even if I tried with several tools selected.
when saving images for the web i try save them as indexed png's to save space.
however, when switching to indexed mode GIMP will alter my colours if i choose to use a palette with less colours than i have in the image. This is the most noticable if for example i have an image with bacgkround #ffcc00 and a multicoloured icon in the middle. due to the icon the image probably has over 100 colours. if i then choose 64 colours not only will it affect the colours in the icon, but change the entire, large, unicoloured background area to maybe fec50a (just an example). is there anyway to force GIMP to only use colours already present in the image?
I'm trying to change colours using the fill tool, but I only get different shades of grey, whatever colour I change it to. I've tested a couple of things and can't work out how to alter this... likewise, the defult patterns also come out in black, white and grey..
Basically I want to merge two images. Both of them are grey originally so I change them to RGB mode and change the colours separately. I then go to copy and paste one image on top of the other and it automatically changes to whatever the colour is of the destination image.
Whenever I open an image in Gimp, it's just a little off colour. Then when I save it as an image file (usually png), it's even more off colour than what's displayed in Gimp. For example, if the image starts out with a grey background of 808080 (RGB Hex Value, 16-bit), in Gimp it's 7F7F7F, and when I save as a png, it's 6E6E6E (honestly, how does that make sense under any circumstances?). I've tried every combination of settings under colour management, to no avail. Once, I managed to get Gimp to display the correct colour, but when I saved it as a gimp file, and re-opened it, it was wrong again.
I would like to replace a range of colors with a single color in an image.
I know there is the replace color adjustment, but this replaces a single color e.g. 190,190,190 with another color e.g. 200, 200, 200. I would like to replace a range of colors e.g. from 185 to 195 with 200, 200, 200.
Problem is, in sky areas, this causes patchy colours and banding issues. However, and this is the strange part, if I convert to TIFF (even using JPEG compression), and then apply the colour matrix, I don't get these issues.
BUT, even wierder, if I then try to convert the fine-looking TIFF image to JPEG again (even with -quality 100), I get these patchy colours again.
This is with GIMP 2.6.12 on a Fedora Linux system.
Today for the first time I have encountered something strange when pulling a PSD file through from CS2 into imageready. The colours in the image seem 'washed out' and faded as per the file attached. I have also attached a file how it should look. I have obviously done something inadvertently to make it go wrong but I can't for the life of me work out what .
Say you have a flattened image, a solid background and text of a differrent colour.
If you wanted to change the colour of the text is there some trick to simultaneously changing the pixels around the letters with slightly different hues (because of the antialiasing) into a relative colour?
i have attached a gif image of a letter zoomed in to give an example.
If you wanted to alter that text to say red could you do it?
I've just used image trace to get a three colour vector of a photograph. I want to replace the three colours in the image with colours from my brand's style guide. At the moment, they're thre shades of a kind of muddy brown.
How I do this? The three colours in the image aren't showing in the swatch menu and I don't really know what I'm doing.
For a project, I've imported a jpeg file that I made on Photoshop. The colors look perfectly fine on the RAM previews and stuff but after I render it, just that specific jpg image comes washed out. It should be dark grey / almost black but after rendering into .mov that image becomes medium grey. It's noticeably more washed out and lighter. All the other colors in that image are also noticeably lighter as well.
I have set my working space to my monitors color profile and I have proofed the colors after saving on Photoshop.
I am trying to make Apple's mostly greenish star space wallpaper for iPhones from iOS 7 (see the attachment #1) into beautiful gradient of colours.
The problem is that I do not know how to do it, so was only able to make a striped version colouring via huge brush, not true gradient.
how I could make a really smooth, gradiental transition between colours?

I have a number of photo images which I need to convert to 6 specific colours and pixelate the image and then sit on a grid (like if you were to make an image using a Rubicks cube to define colour and the grided system).
How would I do this? The grid needs to be 450 x 450 grid cubes (not pixels as I need to show the grid also). Like I say imagine you are using the rubiks cubes to make an image.
I flatten an Image, All the colors change to grayscale. Like if you look at the color chart, you see all the normal colors, but if you try to use a color it just comes out different shades of gray. Its horrible, and it happens everytime.
