Description
I tried to convert a numsharp array with integers to bitmap.
array_rgb_numsharp = array_rgb_numsharp.reshape(1, 300, 300, 3);
Bitmap image = array_rgb_numsharp.ToBitmap();
and encounter this error:
System.InvalidCastException: 'Unable to perform CopyTo when T does not match dtype, use non-generic overload instead.'
How can I fix it?

Start at the ToBitmap() entry point and reproduce the reported reshape and conversion with an integer NumSharp array. Trace the dtype mismatch behind the InvalidCastException and verify that the conversion succeeds for the reported RGB shape without that exception.
