Method Details

getDocument

public static org.w3c.dom.svg.SVGDocument getDocument(String file,
 InputStream in)
                                               throws IOException

Throws:

IOException

getImageSize

public static Dimension getImageSize(String file,
 InputStream in)
                              throws IOException

Returns the default dimensions of the SVG image. Closes the InputStream.

Returns:

the image dimensions

Throws:

IOException - if the image cannot be read

getViewBoxTransform

public static AffineTransform getViewBoxTransform(org.w3c.dom.svg.SVGDocument doc)
                                           throws IOException

Throws:

IOException

getImageSize

public static Dimension getImageSize(org.w3c.dom.svg.SVGDocument doc)
                              throws IOException

Throws:

IOException

getImageSize

public static Dimension getImageSize(InputStream in)
                              throws IOException

Returns the default dimensions of the SVG image.

Returns:

the image dimensions

Throws:

IOException - if the image cannot be read

getExternalReferences

public static List<String> getExternalReferences(String path)
                                          throws IOException

Conducts a recursive depth-first search for external references in the given SVG file.

Parameters:

path - the path of the file to check for external references

Throws:

IOException

getExternalReferences

protected static List<String> getExternalReferences(String path,
 List<String> known)
                                             throws IOException

Conducts a recursive depth-first search for external references in the SVG file named by path. This is a helper function for getExternalReferences(java.lang.String).

Parameters:

path - the path of the file to check for external references

known - the list of references already found

Throws:

IOException

relativizeExternalReferences

public static byte[] relativizeExternalReferences(String path)
                                           throws IOException

Rewrites external references contained in SVG files.

Parameters:

path - the path of the file to be processed

Throws:

IOException

relativizeElement

protected static void relativizeElement(Element e)
