-new option to hide and show the temporary ROIs
-in ROI dock new option for refreshing automatically the temporary ROI while
changing ROI parameters
-in ROI dock new option for automatic plot of temporary ROI
-new option for displaying over the region growing cursor vegetation indexes
such as NDVI and EVI (the latter only for images converted to reflectance)
-new function for displaying the pixel spectral signature with right click on
map using ROI pointer
-new combo box in SCP toolbar for quickly displaying RGB color composites (e.g.
RGB=432 or RGB=4,3,2 or RGB=4;3;2 or RGB=4-3-2) of input image (and automatic
creation of a virtual raster for band set)
-now the window spectral signature plot allows for the display of signature
values in table and calculation of signature distances (separability)
-new tool Split in Pre processing tab for splitting raster bands
-new tool Convert classification to vector in Post processing tab for creating a
classification shapefile
-new tool Reclassification in Post processing tab for the easy reclassification
from Class ID to Macroclass ID and Python expressions are allowed in the
definition (e.g. raster < 3)
-enhanced function Clip multiple rasters
-new reset button for resetting the signature list file
-new button in the classification dock for merging spectral signatures obtaining
a new one calculated as the average of signature values (without covariance
-now classes or macroclasses having ID = 0 are allowed and classified as 0
(unclassified) in the output which is useful for creating masks for classes
-in the signature list it is possible to set the color of multiple selected
signatures at once (pressing shift and double click on a color) and
check/uncheck all with a double click on the checkbox column (S)
-new function (right click with classification preview pointer) displays the
algorithm raster of the preview (a raster where every pixel has the value
calculated by the algorithm for the class assigned to the pixel thereof) useful
for assessing spectral signatures (black pixels are distant from the spectral
signatures and white pixels are closer to the spectral signatures)
-now a classification style (.qml file) is saved along with the classification
output allowing for displaying classification colors when loading the
classification in new qgis projects
-new buttons in tab Band set for exporting the band set to virtual raster or
stacked raster (a multi-band .tif file)
-now the signature file path is stored in the project as absolute or relative
path according to QGIS project settings
-in Settings added an option for the creation of virtual rasters for certain
temporary data (which saves disk space)
-new button in Debug for testing SCP dependencies
