The Microsoft C putimage and getimage functions use a 4 byte header that contains information on the x and y pixel size and the no. of bits per pixel of the block to be displayed. Does anyone know how this header is formed. I think it may be a comination of the above three factors and possibly the graphics mode. Any input would be greatly appreciated. Thank you, Henry Bruce
