[Insight-developers] [Vxl-users] vxl, long long, and 64-bit VS10

[Bradley Lowekamp]

Hello,

I am very much looking forward to this change as it should be a starting ground to enable simple ITK to use uint64_t as a pixel type.

Currently, when the compiler uses long long there is a whole mess of errors, most of them emitting from vxl math functions not having support for long long.

I believe I needed this support to portably wrap some watershed image filters.

I look forward for this change making it into ITK.
