Memory leak in BinarizeSauvolaTiled and BinarizeSauvola

[jli416]

If I run the Pix.BinarizeSauvola or Pix.BinarizeSauvolaTiled functions, they will leak memory and handles. BinarizeOtsuAdaptiveThreshold doesn't cause a problem.

I isolated everything by just passing an 8-bit grayscale image into a large loop in the code below. This leaks about 10MB / iteration (8.5"x11" 300dpi source image) until it crashes because it can't allocate any more memory or resource handles. If I make the loop shorter so that the function ends and the using's dispose, the memory still stays leaked.

Any suggestions?

var converter = new BitmapToPixConverter();
using (Pix pix = converter.Convert(bmp))
{
// Convert RGB to grayscale
using (Pix grayPix = pix.Depth == 32 ? pix.ConvertRGBToGray() : pix.Clone())
{
for (int i2 = 0; i2 < 300; i2++)
{
// Binarize
using (Pix binaryPix = grayPix.BinarizeSauvolaTiled(50, 0.35f, 8, 8))
//using (Pix binaryPix = grayPix.BinarizeOtsuAdaptiveThreshold(50, 50, 5, 5, 0.1f))
{
}
}
}
}

Confirmed, I'll look into it.

Fixed and issued a new release on nuget (2.4.1).
