Black screen after Zoom-to-extent (MinGW)
Mantis Issue 1122, reported by salbert, assigned to salbert, created: 2015-12-17
Black screen is displayed after zoom-to-extent in image-view and/or quicklook-view.
Issue is only reproduced using the MinGW 32/64 bits packages on Windows. MSVC installer and linux build work fine.
MinGW does not use the same version of ITK/OSSIM/Qt/GLEW than MSVC.
1450361377 - salbertMinGW build is linked to OSSIM 1.8.20; MSVC build is linked to OSSIM 1.8.16.
I switched from OSSIM 1.8.16 (system package) to 1.8.20 (custom debug build) on my development Linux laptop and suceeded to reproduce this issue.
I think it is, in some way, related to OSSIM version upgrade.

the image disappears (or blank screen) only if the viewport is negative.
If i zoom or pan in such a way that the viewport x or y is non-negative, I can see the image.
This issue happens only with imagery. ortho rectified or images without geo-information works fine irrespective of my view settings.

./otbcli_ConvertSensorToGeoPoint -in ~/OTB-Data/mv2-test/QB_TLSE_512x512_R_NIR.tif -input.idx -200 -input.idy 128
which outputs:
Output parameters value: output.idx: -nan output.idy: -nan output.town: output.country:
