Title:
  out of disk error not so gracious

Status in Hugin - Panorama Tools GUI:
  Triaged

Bug description:
  SVN3245 Windows XP.

I did not realize that my HDD was nearly full. So I run this HDR full spherical panorama 7000x3500 with enfused output as well as blended HDR and stacked HDR images and it quits with an error and an alert asking to report the error on the bug tracker.

I deselect the HDR output as this is where it happened, and run it again, only to get even faster to the error. This time, I did copy it:

C:\Program\ Files\Hugin\bin\nona -z PACKBITS -r ldr -e 0 -m TIFF_m -o test_exposure_layers_ -i 0 C:\DOCUME~1\coolblu\LOCALS~1\Temp\hug88.tmp

TIFFAppendToStrip: test_exposure_layers_0000.tif: Write error at scanline 0.
caught exception: 
Postcondition violation!
exportImage(): Unable to write TIFF data.

make: *** [test_exposure_layers_0000.tif] Error 1


and I investigated. I found that the files from the previous processes have not been deleted.

We need a more graceful solution here:

1. is it possible to estimate the HDD space required, and compare it against the HDD space available?

2. if not, is it possible to catch the error?
