Create sepia image in ImageMagik or GD (PHP/Apache/FreeBSD)

I would like a one or two line method of creating a sepia image from a black and white image. I am providing both a black and white photo and a sepia copy of the same photo and I would like you to create the sepia image as close as possible to the exact sepia coloring that is provided on the example. We have tied the standard -sepia method in ImageMagick, but the color is WAY off. We have also tried to use the -colorize method but could not find a decent combination of colors to make it look correct.... the white's are always faded out when they should stand out more. We have also tried some freely available PHP classes that use GD to do it, but they have failed as well. I believe that it may take a combination of image magick commands to come up with the solution... I just don't know what they are. In a web-app that we have created people upload their images and a B&W and Sepia image is automatically created for them... this is what this script would be used for. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
