Unless I am doing it wrong, it seems the automatic cropping (enabled in the detection settings) crops down to the point where no pixels will be lost. In other words, this is the smallest crop where all image pixels come through to the final panorama, even if some resultant panorama pixels have no information.
What I want is to have the largest crop where the final panorama has no pixels that lack information. That's not what I get with the auto cropping. What I could do is manually crop the final panorama output using other tools. But that changes the image size and I have to rescale the image from that result. Or I could manually crop in the AutopanoPro crop tool. But I cannot see, while using that tool, if I have reached the crop level that achieves my goal without going through a complete render. I'd have to do quite a few renders to get it right on the border of where it covers as much of the image as possible without getting any empty pixels.
Can someone suggest what I should do?
As described above, I want to first get the crop set to the largest size that will have no empty pixels in the resulting panorama. Then I want to render that panorama at the exact pixel height desired (often a few different sizes), so I minimize scaling artifacts in the various sizes. So I want to get that cropping just right while still in AutopanoPro before rendering.
Here is one of the resulting renders. Notice the pixels along the top and bottom edges.http://phil.ipal.org/autopano/vance-pano/phil_vance-pano_img_1446_img_1469_24_9_5824x720_SCULS.png
