IMAGEFRAME__DEFINE

Name


      ImageFrame

Purpose



      This object implements a class for handling image data. This object is
      conceptually identical to a CatImage object, except that the image data
      is not stored directly in the object. Rather, a pointer to an ImageStack
      object, a frame number, and a slice orientation are used to access the
      image data when needed for display. This object was used in a medical
      imaging application in support of volumentric image data.

Syntax



      imageObject = OBJ_NEW ('ImageFrame', imageStack)
  CLASS DEFINITION:
    class = { ImageFrame, $ ; The ImageFrame object class.
              _stack : Obj_New(), $ ; The IMAGESTACK object.
              _display_mode : 0B, $ ; A flag indicating which display method to use for drawing.
              _inverse : 0B, $ ; If this flag is set, the image is drawn in inverse color.
              _keep_aspect : 0L, $ ; Flag: Keep the aspect ratio when calculating image position.
              _location : DblArr(6,2), $ ; Location information about the "displayed" image.
              _interpolate : 0L, $ ; Flag: When set, bilinear interpolation is used.
              _order : 0L, $ ; Image display order.
              _out_xsize : 0L, $ ; The output X size of the image. (Display_Mode=1 and Display_Mode=2)
              _out_ysize : 0L, $ ; The output Y size of the image. (Display_Mode=1 and Display_Mode=2)
              _position : DblArr(4), $ ; The position of the image in the output window. (Display_Mode=0)
              _xsize : 0L, $ ; The X size of the image.
              _xstart : 0L, $ ; The starting X location for displaying image. (Display_Mode=1)
              _ysize : 0L, $ ; The Y size of the image.
              _ystart : 0L, $ ; The starting Y location for displaying image. (Display_Mode=1)
              _wid : Obj_New(), $ ; The window object where this image should be displayed.
              _window_position: 0L, $ ; The window position for displaying this image. (Display_Mode=2)
              _orientation : "", $ ; The orientation of the slice: "X", "Y", or "Z" (the default).
              _framenumber : 0L, $ ; The frame number.
              _thick : 0L, $ ; The "thickness" of the image slice. (See IMAGESTACK documentation.)
              INHERITS CatDataAtom $ ; Subclassed from CATDATAATOM.
