Hello,

I'm a newbie too, but have you tried Exporting it? From that dialog box you can choose Windows Bitmap (bmp). I'm afraid I don't know what indexes are in this context.

Hello everyone.....

100% Gimp beginner here as u gonna see in my question... :)

How to save an image into BMP? ant then make it indexed?

Thanks to whom may Reply.....

Do control+e to open the Export menu, type in a file name ending in .bmp, and click the magic button...

I was not aware that .bmp images can be indexed; the most common indexed format is .gif. Depending on the number of colors in the .bmp image, .gif may give acceptable results and a much smaller file size on disc.

The logical reason to convert a .bmp file to an indexed format would be to get a that smaller file size for the same size image - .bmp uses /no/ compression to reduce file size, and the result is /big/ image files, while .gif uses an efficient file compression method (that's what indexing is, more or less).

Check here for lots more details - also other pages in the same part of the website:

Read the docs and you will soon know more than me: For instance, I just went poking around and found out that the GIF format uses LZW compression. Just converting to an indexed format would not compress an image /nearly/ as much as doing that /then/ squashing it with LZW.

But not knowing that has not prevented me from using the format successfully, in its proper place (animated dealie-bobs for websites, ror instance), for a loooong time. This stuff is actually simple, from a practical end-user point of view.

some image for a game......i guess Gimp only saves in 24 bit indexed..wich then
i have to run the file into an application that reduces it  to 8 bit indexed format so it can be used in the game......

No, if you convert the image to "Indexed" mode, GIMP will export as 8- bit indexed. If prompted, you probably do want the option to use run- length encoding.
