Panini projection ignores corner handling (Tops and Bots)

[Assaf Toledo]

I’m trying to change the projection of a wide shot (18mm in 35mm terms) from Rectilinear to Panini (General) and I don’t manage to get the corners correctly - it looks like Hugin ignores the values that I set at the Tops and Bots fields.

My steps are to add the image to the image list, open the Fast Panorama Preview screen, go to the Projection tab and set the compression value to 73, and the Top and Bots to 32 each one. Then I enlarge the field of view slightly to fit the image and I close the Panorama preview screen. I go to the stitcher tab, select Calculate optimal size, and press “Stitch!”. The output looks as if the Tops and Bots were left at 0.

Note that if I go to the Crop tab in the preview screen and press Auto Crop, it crops a bar from the top and a bar from the bottom - again, as if the Tops and Bots are at 0.

The file is relatively big so here is a link to download:

Thank you.

It is vice versa: the output is correct, the fast preview is wrong. This is a known bug.

I have to correct me. The fast preview is correct. The remapped output was wrong. This has been fixed in libpano13.
