AForge.Imaging.Filters.Crop causes Exception #98

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
searchImage is a 24bit Jpeg Bitmap (see attachment):

// create grayscale filter (BT709)
Grayscale grayFilter = new Grayscale(0.2125, 0.7154, 0.0721);
// apply the filter
Bitmap bitmap = grayFilter.Apply(searchImage);

Rectangle cropMask = new Rectangle(new Point(0, 0), bitmap.Size);
cropMask.Inflate(-10, -10);
// create filter
Crop cropFilter = new Crop(cropMask);
// apply the filter
bitmap = cropFilter.Apply(bitmap);

// create filter
ResizeBilinear resizeFilter = new ResizeBilinear(this.Size.Width, 
this.Size.Height);
// apply the filter
bitmap = resizeFilter.Apply(bitmap);

What is the expected output? What do you see instead?

System.AccessViolationException

Crop Causes Violation. Dependend on sequence of the Methodcall, Violation 
can also occur at next filter Operation. Even had OutOfMemory Exceptions 
sometimes.
