Creates an ImageView from another view with given type.
No memory is allocated by this operation.
Capabilities of returned ImageView will depend on original ImageView, and will be restricted to (see
#ImageCapability):
- READ
- WRITE
One or many adapters will be added if necessary to convert from input view type to output View type.
Data will be mapped to full output type range. For example, if given view is 16 bits with valueRange
[1000, 2000] and type is uint8, input range [1000, 2000] will be mapped to output range [0, 255].
Input data range are read from view properties. Output range is specified type standard range.
It can be retrieved with DataType::standardRange(type).

Creates an ImageView from another view with given type by mapping dynamic range.
No memory is allocated by this operation.
Capabilities of returned ImageView will depend on original ImageView, and will be restricted to (see
#ImageCapability):
- READ
- WRITE
This method will map [inputRange[0], inputRange[1]] -> [outputRange[0], outputRange[1]]
One or many adapters will be added if necessary to convert from input view type to output View type.
Data will be mapped to full output type range. For example, if given view is 16 bits with valueRange
[1000, 2000] and type is uint8 with input range [20, 50], input range [1000, 2000] will be mapped to
output range [20, 50].
If input image contains value outside of given inputRange, these values will be linearly mapped outside of
outputRange. For example, with [0, 1]->[0, 2], a value of -1 will be mapped to -2.
Warning: No clamp are done for values outside of type admissible values. Invalid ranges may lead to overflow
issues.

This method can be used with frames whose ImageType is not UNKNOWN, but as the new dimension is not given,
the ImageType will be lost (UNKNOWN) in output ImageView.
