jpeg to bmp

[anthony]

as teh image is in memory or a database you will want to do this from some API language, and convert the image strings (known in API's as 'blobs') into Imagemagick images that the API's can work with.

See the main ImageMagick web site. Oh an do play with the command line tools. You can develop your image processing operations using command line then convert them into the API equivalent.

Also visit the relative sections of the forums for various API's. they are not as verbose as this main forum, but they are more specific to the API involved.
