> Project: Commons Imaging
> Issue Type: Bug
> Components: Format: BMP
> Affects Versions: 1.0
> Reporter: Myroslav Golub

> The BMP format allows for negative values of the height field in the header.
> This means that the image lines are stored top-down, not bottom-up as usual
> (i. e. the first pixel in the pixel array would be in the top left corner of
> the image, not in the bottom left as usual). However, when a negative-height
> bitmap is passed, the BmpImageParser attempts to create an array of negative
> length, and a NegativeArraySizeException ensues.
