Detailed Description

This class provides piecewise linear remapping of input pixels to output pixels.

The object's state is represented as:

band0.remap0: ( <segment0>, <segment1>, ...) band0.remap1: ( <segment0>, ... )

The vertices of each linear segment are specified as four numbers in parentheses:

(<min_in>, <max_in>, <min_out>, <max_out>)

A linear function is computed to map min_in to min_out and likewise max_in to max_out, with all intermediate points distributed linearly between the two extremes. Multiple remaps are cascaded: if an input pixel's value falls outside the ranges defined in the first remapper, then the second remapper's table is referenced. The cascading continues until a value is found. If no lookup is available, the output pixel is assigned to the NULL value.

Example: Given object2 with a state of:

object2.type: ossimPiecewiseRemapper object2.remap_type: linear_native object2.band0.remap0: ( (0, 127, 0, 127), (128, 255, 128, 382) ) object2.band0.remap1: ( (0, 382, 0, 255) )

remap0 applied:
The input range 0 <-> 127 passes through with a one-to-one mapping. 128 <-> 255 is stretched out to 128 <-> 382.

remap0 output is fed to remap1: 0 maps to 0 and 382 maps to 255 (compression).

Notes:

1) Currently there is only one remap type (linear_native) is supported so it's not needed but left in the code for future type remaps, e.g. a remap where there is a linear and a logarithmic section.

2) Any number of "remaps" are allowed.
