Interface SVGContext

All Known Implementing Classes:
  AbstractGraphicsNodeBridge, SVGTextElementBridge.AbstractTextChildSVGContext

public interface SVGContext

This interface is the placeholder for SVG application informations.

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.

Method Detail

### getPixelUnitToMillimeter

    public float getPixelUnitToMillimeter()

  Returns the size of a px CSS unit in millimeters.

### getPixelToMM

    public float getPixelToMM()
