[Bug 721136] Re: enblend creates an unexplainable black area.

 

If this problem is symptom of a rounding error in floating-point
operations? Sometimes small rounding errors add up to a glitch in a game
or a pixel. For details on a place where this happens see Wilkinson's
polynomial.

Title:
  enblend creates an unexplainable black area.

Status in Enblend:
  Confirmed

Bug description:
  enblending       http://prive.bitwizard.nl/t80001.tif
  and                  http://prive.bitwizard.nl/t80003.tif
  results in          http://prive.bitwizard.nl/t8a.tif

  I cannot say I expected that black triangle in the output. My enblend
  was pulled from hg this morning (no changes) and built without
  imagecache or openMP. (imagecache causes corruption of the output
  similar but different to this. )
