Method Summary

java.awt.geom.Rectangle2D getBBox()
          Returns the tight bounding box in current user space (i.e., after application of the transform attribute, if any) on the geometry of all contained graphics elements, exclusive of stroke-width and filter effects).

java.awt.geom.AffineTransform getCTM()
          Returns the transformation matrix from current user units (i.e., after application of the transform attribute, if any) to the viewport coordinate system for the nearestViewportElement.

float getFontSize()
          Returns the font-size on the associated element.

java.awt.geom.AffineTransform getGlobalTransform()
          Returns the global transformation matrix from the current element to the root.

float getPixelToMM()
          Returns the size of a px CSS unit in millimeters.

float getPixelUnitToMillimeter()
          Returns the size of a px CSS unit in millimeters.

java.awt.geom.AffineTransform getScreenTransform()
          Returns the transform from the global transform space to pixels.

float getViewportHeight()
          Returns the height of the viewport which directly contains the associated element.

float getViewportWidth()
          Returns the width of the viewport which directly contains the associated element.

void setScreenTransform(java.awt.geom.AffineTransform at)
          Sets the transform to be used from the global transform space to pixels.
