Working with Rasters
and Grids
The MapInfo.Raster namespace contains all of the classes that control the use
and display of raster and grid images in MapXtreme. Rasters are computer
graphics that are composed of pixels that render a whole image. Many satellite
images are rendered as raster images. Grid images are thematic maps that
show a continuous gradation of color to represent interpolated information.
