Apologies to everyone. Philip had the key. The images are displaying correctly. I apologize for sending everyone on a wild goose chase.
The problem was simply that given the particular image, comparing the images one on top of the other made it hard (for me, at least) to see the transformation. So, I tried something akin to what Philip did. I took a screen shot of each of the images at the top of this thread, as they appear in the thread. I loaded both into Irfanview, aligned the the Irfanview windows
side by side and took a screen shot of that. Voila:
the dimensions are hard to see in the screen shot, but they too are correct.
Again, apologies to everyone. And thanks for clearing this up for me.
