scalingMode

enum scalingMode

For setting mode of conversions between unsigned and signed numbers, and between integers and floats.

Consider scaling a signed char image to unsigned short image . The former one takes values in range [-127,128], the latter in range [0,65535].

• NONE: negative values will be mapped to undetectValue, positive ones as such to [0,128].
• HALF: negative values will be mapped to undetectValue, [0,128] linearly to [0,65535].
• RANGE: -127 will be mapped to undetectValue, 128 to 65535, and linearly between these.

Assume that the latter will

TODO: is this [0...1] limitation for floats valid?

For floating-point values, returns 0.0, otherwise the lower limit of the range.
