sub-cm/pixel export resolution rounded down to zero resulting in null exports

[patcoyle]

New issue identified when Jeff Warren, solved issue noted below. He noted when increased export resolution from 0.39 cm/pixel to 1/pixel, the 5 image map exported. Code appears to have rounded down to zero resulting in null exports. Prior solved issue: Thanks Jeff. Interesting issues in results from this try: http://mapknitter.org/map/view/livermore-ca-test-with-pl-mobius-infragram-point-and-shoot-on-parrot-ar-drone-2-0 Exports as jpeg and webviewer seem null or empty. Edit map initially shows locked set of images as displaced, but seem to line up if pan in the editable map window. All, may be function of the very low altitude images. Can't zoom in more to place them better. I'll note this in GetHub, but may just be due to this extreme case.

Hi, Pat - related; I also added a very high zoom capability to the new mapping interface; it's still very early prototype and buggy, but you might take look; if you change the background layer to OSM, you can zoom all the way to zoom level ~23, and really see your images full size.

There's also a "high res" button on the side that loads the full resolution images; very nice. @eustatic might want to take a look too.

Thanks Jeff,

This is very neat and does get us right in close.

Scott, I liked your reminder that this is useful for the PAP mappers as well.

Have safe and happy holidays.

Pat
