Pixel size of output file

Asked by Vin

I have a question regarding the default pixel sizing of the output panorama.

For example, I was stitching 2 pictures of a horizontal panorama, each picture being 3648 pixels in height. However, despite the vertical alignment being almost perfect (and therefore, there must have been very little cropping made due to one picture being a bit "higher" or "lower" than the other), I notice that the default output for the panorama is barely 2800 pixels in height.
Again, it seems unlikely that i lost almost 1/4 of the pixels due to cropping.
I have already noticed some random default outputs that do not seem to correspond to the original file size. How does that work? Is this loss of pixels unavoidable?

And second question: in my example, what would happen if I set a new output file size with a height of, say, 5000 pixels? What kind of resampling is used?

The used resampling method can be selected on the stitch tab under nona options. (For new projects you can set the default under preferences, tab programs.)

Can you help with this problem?
