Constructor Detail

### BlockViewport

    public BlockViewport()

  Create a new block viewport area.

### BlockViewport

    public BlockViewport(boolean allowBPDUpdate)

  Create a new block viewport area.

  Parameters:
    `allowBPDUpdate` - true allows the BPD to be updated when children are added

Method Detail

### setCTM

    public void setCTM(CTM ctm)

  Set the transform of this viewport. If the viewport is rotated or has an absolute positioning this transform will do the work.

  Parameters:
    `ctm` - the transformation

### getCTM

    public CTM getCTM()

  Get the transform of this block viewport.

  Returns:
    the transformation of this viewport or null if normally stacked without rotation

### setClip

    public void setClip(boolean cl)

  Set the clipping for this viewport.

  Parameters:
    `cl` - the clipping for the viewport

### hasClip

    public boolean hasClip()

  Returns true if this area will clip overflowing content.

  Specified by:
    `hasClip` in interface `Viewport`
  Returns:
    `true` if the overflow trait has the value "hidden", "scroll" or "error-if-overflow"

### getClipRectangle

    public java.awt.Rectangle getClipRectangle()

  Returns the clipping rectangle of this viewport area.

  Specified by:
    `getClipRectangle` in interface `Viewport`
  Returns:
    the clipping rectangle expressed in the viewport's coordinate system, or null if clipping is disabled
