Tool for pixel value scaling #54

Closed avalentino closed 11 years ago

Currently pixel values are scaled before displaying in order to improve the image readability. The scaling factors are currently computed using a simple algorithm based on coarse statistics. The algorithm for automatic computation of scaling factors should be improved and a tool for manual setting of scaling factors should be added.

Completed in r660.

A new ''stretch'' plugin have bee added. It allows the user to change via GUI the stretching parameters of single channel raster bands. Currently only linear stretching is supported.
