Functions in this menu can be applied only to raster layers. The raster layer need to be loaded with "Sextante Raster" option from the File>>Open menu.

functions:

  • Create Lattice from Raster - creates a point dataset from the raster layer, each pixel will be one point with an attribute table containing the gray or RGB values.
  • Create Polygon Grid from Raster... - creates a polygon layer from the raster layer, each polygon will correspond to one pixel with an attribute table containing the gray or RGB values.
  • Profile Graph... - displays a profile plot of the values of the selected raster along a line.
  • Raster Color Editor... - allows to change the color schema of the raster. Note that the color changes may be only visible after a panning or zoom operation that calls the screen-refresh function.
