Hmmmm.
I don't understand why anyone would think there might be something
done to the file.
And that bit of code results in MUCH more than just setting aside space
for the image. If it was THAT simple, then the requirement that it fit a
"window" is satisfied if you just show the upper left 1/4 of it.
But instead, Arachne PROCESSES the image by throwing away certain pixels
(for downsizing) or duplicating certain pixels (for upsizing) and then
puts ONLY the selected pixels in the "window" - effectively resizing
the image as shown on the screen. I think this is pretty easy to grasp.
You just have to remember that a pixel is a pixel and you CANNOT change
a pixel's size without switching video modes. (640x480 --> 800x600)
So the ONLY option is to drop/add FULL pixels - or averaged values for
full pixels if one spends more processor time on it than Arachne does.
The resultant bitmap in video memory is a resized image, occupying no
more data space than necessary and in the above example, that's 1/4 of
the data space of the original file.
The only thing missing is our ability to save ONLY THAT PORTION of the
video memory.
