Hm, so that's why my mercator projection + straight line @ ~25° was throwing off the alignment... so this means that: equirectangular: vertical lines only, plus horizon line Does this also apply to cylindrical, mercator, miller, architectural ? (i'm using mercator) That explains the GSoC idea of moving "line" control points to the preview windows. > Yes, it is useful.

Only problem I see with horizon control lines, is that unlike straight lines they only specify two points. Horizontal CPs are more effective further apart, however all the intermediate images are not straightened: they can be wavy/squiggly. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
