  • Constructor Details

    • MemoryGray8Image

      public MemoryGray8Image(int width, int height)
      Creates a new MemoryGray8Image object with the specified resolution. Simply gives 1 (for one channel) and the two resolution arguments to the super constructor (of the parent class MemoryByteChannelImage).
      Parameters:
      width - the horizontal resolution, must be non-zero and positive
      height - the vertical resolution, must be non-zero and positive

    • createCompatibleImage

      public PixelImage createCompatibleImage(int width, int height)
      Description copied from interface: PixelImage
      Creates an instance of the same class as this one, with width and height given by the arguments.
      Specified by:
      createCompatibleImage in interface PixelImage
      Specified by:
      createCompatibleImage in class MemoryByteChannelImage
      Parameters:
      width - the horizontal resolution of the new image
      height - the vertical resolution of the new image
      Returns:
      the new image

    • getImageType

      public Class getImageType()
      Description copied from interface: PixelImage
      If there is a single interface or class that describes the image data type of this class, the Class object associated with that interface (or class) is returned (or null otherwise). This Class object, if available for two image objects, can be used to find out if they are compatible. Example: MemoryGray8Image returns net.sourceforge.jiu.data.Gray8Image.class.
      Specified by:
      getImageType in interface PixelImage
