Fast pano preview doesn't show anything anymore

[hvdwolf]

This happens on OSX 10.6.4, maybe other OSes and versions as well.

Hugin version 2010.5.0 4933:00cf24063a08 doesn't show anything anymore in the Fast preview screens. In the first "Preview" when "tick marking" the "Show control points" they are displayed on a black background. Only the Layout pane still shows the images.

Hugin version 2010.5.0 4886:a1cb4a2efa65 did this correct.

Works ok here (2010.5.0 4933:00cf24063a08), fedora f13.

i see the same thing (black window except for the layout tab) on debian. tracked it down to commit 4929. the latest version (4939) works if i comment out the force update of crops part.

Same here on Fedora 14.

I see images in the layout view, bit not any other pane. The same is true for the old preview window.

Ok, I see it now in some projects.

Basically everything is fine so long as the input photos are cropped in the Crop tab, if you click 'Reset' in the Crop tab such that there are no crop parameters then the photo vanishes.

If the crop is set to the dimensions of the photo, the photo is effectively 'uncropped', but it appears in the preview.

Presumably no photos would appear if you start a new project without any cropping of the input photos.

the culprit is actually line 1322 in Panorama.cpp

  state.images[imgNr]->setCropRect(vigra::Rect2D(0,0,0,0));

why is the crop rectangle set to 0? if i comment this out i get the images back.

Fix works OK.
I will await comment from others but as far as I'm concerned the ticket can be closed.
