Parameters

  • isTopmostGrid
    Type: System.Boolean
    Indicates whether the grid is a top level (level 1) grid.
  • rGridMinX
    Type: System.Double
    The x-coordinate of the lower-left corner of the grid.
  • rGridMinY
    Type: System.Double
    The y-coordinate of the lower-left corner of the grid.
  • cGridRows
    Type: System.Int32
    The number of rows in the grid.
  • cGridColumns
    Type: System.Int32
    The number of columns in the grid.
  • touched
    Type: array<System.Boolean[,]
    A two-dimensional array of bool values that specifies whether the cells touched the object.
  • contained
    Type: array<System.Boolean[,]
    A two-dimensional array of bool values that specifies whether the cells contained the object.
  • cCellsTouched
    Type: System.Int32%
    When this method returns, contains the number of cells that the object touches.
  • cCellsContained
    Type: System.Int32%
    When this method returns, contains the number of cells that the object contains.
  • fGeometryExceedsGrid
    Type: System.Boolean%
    When this method returns, contains a value that indicates whether the object exceeds the grid.
  • fHasAmbiguousTouchedCells
    Type: System.Boolean%
    When this method returns, contains a value that indicates whether the object includes ambiguously touched cells.
