nanogui: Thread: Re: 16bpp bmp error

>    i rewrote the  image loading routine for bmp so that , instead of
allocating the entire image memory , allocate for one row of data and resize
it to the destination image .  I am able to read and write the 8,24 bmp
images correctly , but 16-bpp images are not resizing properly. Am i missing
something ... help needed.


              case 2:{
                       unsigned short pixel = 0;

                       pos1 = 0x10000;
                       for ( i = dstwidth; i >= 0; --i ) {
                           while ( pos1 >= 0x10000L ) {
                               pixel = *srcp++;
                               pos1 -= 0x10000L;
                           }
                           *dstp++ = pixel;
                           pos1 += inc1;
                       }
                   }
                   break;


*****
In the above routine for the  16 bpp case, you're writing only
a single byte (*dstp++ = pixel), when you need to be writing
2 bytes for the 16 bpp case.  Check out how three bytes
are written (r,g,b) in the "case 3:" below for 24 bpp.

This will fix your problem.
