If you are using the libtiff library, you will need to open the four input files, create an output file with PHOTOMETRIC_SEPARATED, SAMPLESPERPIXEL=8, and PLANARCONFIG either SEPARATED or CONTIG. If you choose CONTIG you will have to interleave the input pixelsl. For SEPARATED you will call TIFFWriteScanline 4 times for each scanline, incrementing the value of the color arg.

If you need a commercial application, our company has several products which will meet your requirements. Piktor and tiffcombine
