With C++ and Qt how do I display a 16-bit raw file as an image?

Question

I am looking to display heightmaps from the video game Battlefield 2 as images in my application.
I am new to C++ and Qt and it might be straight forward but what I am h

Answer 1

Just a guess. Maybe try something like this?

#include 
...
QByteArray data=file.readAll();

// create an empty image of the right size.  We'll use 32-bit RGB for simplicity
QImage img(1025,1025, QImage::Format_RGB32);

// Access the image at low level.  From the manual, a 32-bit RGB image is just a
// vector of QRgb (which is really just some integer typedef)
QRgb *pixels=reinterpret_cast(img.bits());

// Now copy our image data in.  We'll assume 16-bit LE format for the input data.
// Since we only have 8 bits of grayscale color resolution in a 32-bit RGB, we'll
// just chop off the most significant 8 bits (the second byte of each pair) and 
// make a pixel out of that.  If this doesn't work, our assumption might be off --
// perhaps assume 16-bit BE format.  In that case we'd want the first byte of each
// pair.
for (size_t i=0;2*i

edit: oops, QImage::Format_RGB32 instead of QImage::Format_RGB
