public class HwmfGraphics extends Object
  • Constructor Details

    • HwmfGraphics

      public HwmfGraphics(Graphics2D graphicsCtx, Rectangle2D bbox)
      Initialize a graphics context for wmf rendering
      Parameters:
      graphicsCtx - the graphics context to delegate drawing calls
      bbox - the bounding box of the wmf (taken from the placeable header)
  • Method Details

    • getProperties

      public HwmfDrawProperties getProperties()
    • draw

      public void draw(Shape shape)
    • fill

      public void fill(Shape shape)
    • getStroke

      protected BasicStroke getStroke()

      protected Paint getSolidFill()
    • getHatchedFill

      protected Paint getHatchedFill()
    • getPatternPaint

      protected Paint getPatternPaint()
    • addObjectTableEntry

      public void addObjectTableEntry(HwmfObjectTableEntry entry)
      Adds an record of type HwmfObjectTableEntry to the object table. Every object is assigned the lowest available index-that is, the smallest numerical value-in the WMF Object Table. This binding happens at object creation, not when the object is used. Moreover, each object table index uniquely refers to an object. Indexes in the WMF Object Table always start at 0.
      Parameters:
      entry -
    • applyObjectTableEntry

      public void applyObjectTableEntry(int index)
      Applies the object table entry
      Parameters:
      index - the index of the object table entry (0-based)
      Throws:
      IndexOutOfBoundsException - if the index is out of range
      NoSuchElementException - if the entry was deleted before
    • unsetObjectTableEntry

      public void unsetObjectTableEntry(int index)
      Unsets (deletes) the object table entry for further usage When a META_DELETEOBJECT record (section 2.3.4.7) is received that specifies this object's particular index, the object's resources are released, the binding to its WMF Object Table index is ended, and the index value is returned to the pool of available indexes. The index will be reused, if needed, by a subsequent object created by another Object Record Type record.
      Parameters:
      index - the index (0-based)
      Throws:
      IndexOutOfBoundsException - if the index is out of range
    • saveProperties

      public void saveProperties()
      Saves the current properties to the stack
    • restoreProperties

      public void restoreProperties(int index)
      Restores the properties from the stack
      Parameters:
      index - if the index is positive, the n-th element from the start is activated. If the index is negative, the n-th previous element relative to the current properties element is activated.
    • updateWindowMapMode

      public void updateWindowMapMode()
      After setting various window and viewport related properties, the underlying graphics context needs to be adapted. This methods gathers and sets the corresponding graphics transformations.
