GIMP :: Indexed Color Conversion Error
Aug 23, 2013
I have been having a problem with Gimp. I am currently working on a Gif banner for a webpage. The banner itself is 728x90 pixels. It has 186 different layes as well, some of which are inside of folders. The xcf itself is complete, but the only other stage I need to complete is converting it to Indexed colors so I can export it as a gif; however, whenever i access the Image>Mode tab, the "Indexed" button isn't highlighted, and I am unable to click on it, even with the keyboard commands. I haven't been able to find a solution so far. Here's a picture of the problem.

I was quite surprised this image I found was an indexed color profile... when I was new (and dumb) to Gimp and images in general I used to save transparent gifs rather than transparent pngs... because I didn't know PNGs could be transparent but Gimp would warn me about that it would convert to indexed and I'd lose A LOT of color & clarity... none of my indexed images were very clear nor this colorful... how is it possible to obtain such color and clarity in an indexed color profile like in the image attached?

I have a great picture of Jet Jaguar. I'm interested in pixel art, so I reduced the colors to an indexed 16 colors.
I want to save the 16 colors in this pic to a palette for later, but how? I've been looking in vain through the menus for a way to save this color map as a palette. Maybe there's a script or plugin somewhere, but it is hard for me to believe there isn't a built-in way to do this.

i just started using gimp on ubuntu 13.10 . almost half of the menu items are greyed out. most of the filters work or ar not greyed out, g'mic is greyed out and so is most of the stuff in the file menu (export, save, save as, etc.) . i already tried re-installing gimp from the software center with no prevail. this is how it was the first time i installed it on this new ubuntu 13.10 .
is there something that i can do to maybe refresh the entire gimp folder maybe? maybe delete it then re-install gimp. i really dont know if this would fix anything though.
this is really irritating. and no its not the "image RGB/indexed mode" problem.
im pretty sure i dont have anything installed (like some weird ubuntu restricted access fake file) that could interfere with the interface at all as this is a pretty fresh installation. the most i have installed that might even be close to interfering with the interface is "pipelight" which is for flash and silverlight, not gimp.
i even tried different color profiles and none of them work. i even downloaded the brand new color profiles from adobe. none of those work either.
the only way i got ALL of the menu options back, including g'mic, was opening gimp through raw therapee (basically adobe lightroom for ubuntu) which might be of some use in finding an answer to this?
i already have everything i need installed including the ubuntu restricted access extras and such.i just would like gimp to open normally with all the normal file menu options enabled like everyone elses and not be all greyed out ..

I bought a Pepin press book & cd, of wallpaper patterns. They are not in the rgb mode, but the (what is it? ) CYBK? mode. When I load them onto gimp the colors are way off.
Apparently gimp converts them to rgb mode, but the colors are glaring & clashing.

Whenever I open a photo with my Adobe Photoshop Elements 9, I get the following message:
The monitor profile “LCD color management and conversion” appears to be defective. Please rerun your monitor calibration software.”
Following the message are 2 buttons: “Ignore Profile” and “Use Anyway.”
What do I need to do?

The color swatches in the 64-bit version of Photoshop CS4 do not change to the used swatches for the indexed image, rather they show the default colors for Photoshop. I looked to see if there was a setting to show the colors in use, but alas there is none. Is this a feature or a bug?

why the size on disk of uncompressed indexed color images is always slightly larger than you expect it to be? For example, a 100x100 pixel image, 4 bit indexed image with a 2 color palette: the file size should be 5,000 bytes (4 bits for each of 10,000 pixels) plus 6 extra for the two colors in the CLUT - i.e. 5006 bytes. Yet the actual size is 5,268 - not a figure that squares with any size of palette! Ditto a 200x200 image, 8 bit colour: 40,000 bytes. Plus a full 256 colour CLUT at 3 bytes each, an extra 768. total size 40,768. on disk it is 41,080 bytes - an extra 112 bytes.
This is on a PC - not a Mac 'resource fork' issue. Is there some additional header info that Photoshop attaches to indexed color images -

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.

I have 32bit TGA images files and want to convert them into 32bit BMP, preserving the alpha channel (very important).
I have about 2000 files I need to convert. Doing it manually using gimp, I just open the image, save as and change the extension to bmp. I leave every other setting to default.

I've been using corel draw since version 4, and I love it. Now on x5 I cannot figure this out. I use eps files for printing large format with contour lines for cutting. My setup uses a spot color defined as "CutContour" for cutting. It seems x5 renames these colors or converts them to something else. I opened the same file in 12 and had to Reclick the same color for the cutter to see it and it worked fine. Any setting to change this?

I'm using CS3. In the Camera Raw 4.6 import window the color looks great. When I get the image into Photoshop the color looks horrible. I know it's the color profile that Raw is assigning. My question... is there a way to disable the color profile conversion coming from Camera Raw?
I've always had great results without using profiles and now this alters my color. I've even tried to go in and force the image to use a different color profile but at this point the damage has been done by the camera raw plugin.

I need to convert from bitmap images to PNGs with the command line. I've tried looking into script-fu, but lisp is one of those languages I could never figure out.
I've tried using imagemagick, but it did not properly convert the images. The images are apparently 32bit Windows Bitmap V3 files with an alpha channel; according to a page I found on google, imagemagick will not preserve the alpha channel in this particular case. I don't know for certain if that's the actual reason why imagemagick isn't working, but it definitely isn't working. It does, however, work if done manually in gimp.
This is going to be part of a python script, so I need it to convert a specific bitmap file rather than all the ones in a directory.

We would like to use Gimp for a small set of image conversion experiments. Unfortunately, the system where we want to install and run Gimp belongs to a US Govt agency, the environment is secure and their data is extremely sensitive. So we need to get their approval before we can install Gimp. To get it, we need to provide information on whether Gimp is "US-based" or "foreign-origin". We don't have a strict definition of what either of these terms means, but I am wondering if you have encountered these questions before. Can you tell me what the geographic origin of the tool is? Do you know of any specific instances of your tool being installed at any US Govt locations with sensitive environments?

For our sublimation printing, we use Corel X3,
For some time we have problems with the colors.
As standard pallette we use Pantone Coated, but after I export a .cdr to .eps some colors are replaced with a new color with the same name, when I open it in Coreldraw again afterwards. The colors are placed in a new user pallette and have different CMYK values.
How knows how to keep my PMS coated pallete?

I recently installed Autocad 2014 with Carlson Survey 2014. When I use Etransmit or file conversion i get a Fatal Error. when i uninstall the civil 3d object enabler, the problem goes away, but i need the object enabler and i need to convert files. Is this not a major issue that Autodesk would consider important enough to address, or is the object enabler minor in comparison to other issues?

When a mixed RGB/CMYK PDF is opened in Illustrator CS6, Illustrator forces a conversion to one color space or the other. See this screenshot: [URL]
I assume this is a limitation of Illustrator and there's no way to keep both color spaces. Under that assumption, Is it possible to choose the profiles used for the conversion from RGB to CMYK? Can Illustrator be made to use the RGB and CMYK profiles defined in its Color Settings to make this conversion?

I have a text layer with width given at its creation. When I later open text editor and enter some wider text, it is wrapped to second line. So I would like to enhance the width of the layer to prevent this. When I add width to the layer using "Layer Boundary Size" menu item, text layer gets converted into standard bitmap layer . I don't understand the logic why a text layer isn't preserved on change of its size .
Is there a way how I can adjust size of text layer without its conversion to a bitmap?

I am having trouble with the Color Table in Photoshop. Basically I have an indexed PNG-8 file with 8 colors, and I want to export it's palette to a .ACT or .PAL file.
But when I go to "Save..." in Image/Mode/Color Table, Photoshop seems to be filling up the rest of the palette all the way to 256 colors, with shades of gray... instead of ONLY the 8 colors I have in my PNG (including transparency).

I installed Photoshop Elements 10 on my new iMac (previously installed on my older imac). After installing the software and launching the organizer, it asked me to index my photos. Custom reindexing 11000 plus photos is not a pleasant thought. How do I find my old index, either on my new mac or on my time machine backup?

I'm creating a little icon to be used on another site (entering a contest), and they mentioned something about needing to be "indexed .pngs" to be compatible with recolors and palettes.

How I choose a color for any new objects I want to create. I've opened the toolbox with ctrl-b, which appears on the left side of the window. If I want to , for example, draw a red rectangle, I use the rectangular selection tool, then the bucket fill, and I don't see how to change the foreground color to red.
I've read elsewhere in the forum that there should be two rectangles somewhere on the screen that show foreground and background color, but I don't see them anywhere.

I am a texture designer as a hobby for an online game called Eternal Lands.
Ususally I just make my own textures, but I wanted to edit an existing texture this time. The texture is for armor called Red Dragon Armor, it has red scales on it.
I want to replace these red scales (without taking away the details such as the streaking and the scratches) with gold. I tried using "Color select" then "colorify" but it didn't come out quite right.
What is the usual method for changing the color of a section of an image if there are details and you don't want to use the "bucket fill" option?
