PBMLIB - Portable Bit Maps
PBMLIB is a collection of FORTRAN routines for creating and reading Portable Bit Map files (PBM). Both ASCII and binary formats are supported. The library can also handle the related Portable Gray Map (PGM) and Portable Pixel Map (PPM) formats. There are many graphics programs, such as XV and GIMP, that can display images in these formats, or translate them to other formats such as BMP, GIF, JPEG, MacPaint, X Window, and so on. A C version of PBMLIB is available in PBMPAK . PPMA_2_PPMB is a sample application that converts ASCII PPM files to binary PPM files.pbmplus - image file format conversion package Fetch the software. PBMPLUS is a toolkit for converting various image formats to and from portable formats, and therefore to and from each other.

True-Color GIF Example « Williamo's Blog
i Rate This The mistaken belief that GIF has a limit of 256 colors probably comes from the way GIF was first used when it came out. In the late 1980′s, PC video cards generally supported no more than 256 colors. Image exchanges were becoming popular among BBS systems and the Internet and viewer programs were quickly produced.
By Alex, on July 3rd, 2007 To recap the process needed to use a library: Once per library: 1) Acquire the library. Download it from the website or via a package manager. 2) Install the library. Unzip it to a directory or install it via a package manager. 3) Tell the compiler where to look for the header file(s) for the library. 4) Tell the linker where to look for the library file(s) for the library. Once per project: 5) Tell the linker which static or import library files to link. 6) #include the library’s header file(s) in your program. 7) Make sure the program know where to find any dynamic libraries being used.

True-Color GIF Example
The three images to the left demonstrate the difference between a spectrum of 32697 colors and the same spectrum reduced by quantization to only 256 colors. All three images are in GIF format. All three conform to the GIF89A format specification as published by Compuserve. The big difference is that the ANGIF library was used to generate the true color GIF directly from the data buffer in the program that created the spectrum of colors in the 217 x 217 pixel image.ANGIF is a C library to generate GIF format output. It can generate animated GIFs or true-color (24-bit) GIFs (using both at the same time, however, does not display properly on common browsers). ANGIF is completely LZW-free. There is no code implementing the patented LZW algorithm. That also means there is no compression and the files will actually be larger than a raw file with the same image by about 13% to 16% more.
