Hey everyone,
I am currently using 2.6.4, but was making some panos with 2.6.3 as well I think. I have Win 7 64 bit.
I was making some panoramas and noticed that the auto-crop tool is not cropping effectively. I noticed this after I made a whole lot of new panoramas and saw that there were often black areas on these panoramas. I knew that I had used the auto-crop feature to crop the panoramas but apparently this was not working correctly. I went back and tried it again and then realized that it is a very subtle effect. Here are some examples:
I start with 6 images.
I autocrop as shown
It previews as such.
Then I render the image.
The product is okay, but notice the left upper corner and along the top edge! There is black.
Going back to APP, the auto-crop function didn't line the box up with the real edges of the panorama.
Does anyone have any thoughts? This is quite time-consuming to fix.
Would love to get people's input on it.
Thanks!

Did you try setting the crop manually to the values you want?

The algorithm uses to find the auto crop is not exact but approximate and it may happen in seldom cases that it does leave a bit of black.
We didn't find yet the right solution for that, because making a pixel accurate autocrop on an image that doesn't exist yet is a bit complicatd.

Hi everyone,
I'm of course able to adjust this manually, and have done so. However, this has never happened to me except recently. The auto-crop has always worked perfectly for hundreds on previous panoramas that I have made.
Has anything changed recently in the algorithm?
It saves a lot of time when it works right.
Thanks!

No change in 2.6.4 compared to 2.6.3. It may work 99% of time and fail in one occasion then.
