Bitmap.ToArray() does not handle images with odd width #457

Closed AmbachtIT closed 7 months ago

AmbachtIT commented 2 years ago

Reproduction

Have an image with an odd width (for instance: 475x554x3)
Load it into an NDArrayusing Bitmap.ToNDArray();

Expected result

An array with shape (1, 554, 475, 3)

Actual result

throws IncorrectShapeException: Given shape size (789450) does not match the size of the given storage size (791112)

Root cause

The method ToNDArray() does not handle odd shapes correctly.

Fix

I have been able to reproduce the problem locally and implement a fix. PR will be following shortly.

Image used for reproduction
