Decode JPEG to receive uncompressed data

Question

I want to decode JPEG files and receive uncompressed decoded output in BMP / RGB format. I am using GNU / Linux and C / C ++.

I looked at libjpeg, but there seemed to be no good documentation. So my questions are:

• Where is the libjpeg documentation located?
• Can you suggest other C-based jpeg decompression libraries?
