Description

When you rotate the image at the end of processing, the aspect ratio is no longer maintained (e.g., 16:9), and part of the image may be cropped out of the frame even when using the “Largest Area” option.
Attached are the RAW file, the XMP file, and the two JPG photos showing the last two steps of processing.

Research direction

Start by reproducing the rotation workflow with the supplied 20260626__0080_01.zip archive, using its RAW and XMP files and comparing the two JPG results. Trace the pan-and-tilt processing entry point and verify that the final rotated image preserves its aspect ratio and keeps the full image visible with “Largest Area” selected.
