Hi John, I'm just catching up on my email, do you have access to the Hugin repository yet? If not, then send me your sourceforge username. Note that sourceforge supports a fork/pull-request workflow (similar to github), so you can work on a separate personal repository just as easily as the main

It now appears to me that the limitation may be in the device driver (Nvidia). There is quite a lot to this malfunction that seems to me to be almost impossible to fit into the theory that the malfunction is in the driver. But I've stepped through the code down to the point that the image is

I guess I posted too early in the morning, while rushing out to shovel snow. When I did the testing, I was careful about correctly computing the 2**27 zoomed image size. In my above two posts, I wasn't: 7035x4730 is just over 2**25 so at 200% it should fail. I was correct the first time that

I don't have Windows here, I have Linux, with Nvidia's driver, v 460.91.03. Which version of Hugin is this? I have v2021.0.0.52df0f76c700. Just tried zooming in on some of my biggest panoramas, didn't encounter any problems. On 1/29/22 03:09, johnfi...@gmail.com wrote: I don't actually know

In my experimentation for 400% and 800% magnification, I am experiencing a malfunction (entire image displays as black) when the magnified image is over 134217728 pixels. I have a bad code change work around for the problem and will figure out a better code change. *Who do I ask for the
