---|---|---|
pixel sample size | 5 | How many pixels (x1000) are sampled during
alignment. Impacts execution time. |
jpg save quality | 85 |
Quality vs compression for jpg files. Explained below. |
pano lens mm | 40 | Curves images in the overlap area to
make alignment possible. |
pano lens bow | 0 | Compensates for lens barrel distortion. |
pano prealign size | 500 | Image size (pixels) for prealignment. Explained
below. |
pano mouse leverage | 2 | Mouse movement pixels to drag the image by 1 pixel. This makes precise control easier. |
pano align size increase | 1.6 | Image size
increase at each alignment stage. Reduce if you have problems. Impacts execution time. |
pano blend reduction | 0.7 | Image comparison area reduction at each
alignment stage. |
pano minimum blend | 10 | Final image comparison area, in percent of image
size. |
