Grayscale image histogram adjustment

This project requires the development of a C language program in a DLL or EXE form under Microsoft Visual C++ 6.0 or later for adjusting histogram of an image (apply new shadow, midtone and highlight.) This is similar to Adobe Photoshop's Adjust Levels function. Given an 8 bit or 16 bit grayscale image in TIFF or RAW format, this function will take as input the new Shadow, Midtine, Hilight and a pointer to raw data image values and adjust the image accordingly to apply the new tone values. No viewer or other user interface function is needed. Here is an example:

OpenandAdjustImage()

{

... open the image file and retrieve image data

... put image data into a buffer called BUFF

AdjustHistogram(10,180, 200, &BUFF);

.. write the image image returned in BUFF back to disk with a new file name preserving the original image

}

void AdjustHistogram(int shadow, int midtone, int highlight, char *BUFF)

{

...

...

}

Input variables are shadow, midtone and hightlight values (between 0 and 255 for 8 bit grayscale images and between 0 and 65535 for 16 bit grayscale images) as well as a pointer to the raw image data memory. Once the function is finished, it will modify the values for each pixel in BUFF buffer and return.

I am six year experienced in c++ programming. At university I made applications doing this stuff as a homework. It does not take much more time to do this project for me.
