> If users have ImageMagick installed and they select image preprocessing, one of the things we are currently doing is telling ImageMagick to expand the image by 900%.  This _may_ make sense for small images..tbd...however, this can lead to massive files and dramatic increases in processing time.
> At some point, we should probably increase the image size based on the initial image size, e.g. dynamic resizing.
> Until then, for Tika 2.0.0, I propose that we change the default to 200%.  This value is completely heuristic and not based on much data aside from Peter Kronenberg's work: https://lists.apache.org/thread.html/rb1dece05760d10f1b165b03b97fef8b609dc40c4cd06bdb8cc36469d%40%3Cuser.tika.apache.org%3E
