Method Detail

getIndex

public static int getIndex(NamedNodeMap namedNodeMap,
                           Map<Integer,List<String>> attributesOrderMap,
                           Node element,
                           int requiredIndex)

Forward the call to the correct helper.

Parameters:

namedNodeMap - the node map

attributesOrderMap - the order map

element - the node

requiredIndex - the required index

Returns:

the index or requiredIndex

getAttributesOrderMap

public static Map<Integer,List<String>> getAttributesOrderMap(Document document)

Returns internal Xerces details about all elements in the specified document. The id of the returned Map is the nodeIndex of an element, and the list is the array of ordered attributes names.

Parameters:

document - the document

Returns:

the map of an element index with its ordered attribute names

getRenderingBackend

public static RenderingBackend getRenderingBackend(int imageWidth,
                                                   int imageHeight)

Parameters:

imageWidth - the width of the image this backend is for

imageHeight - the height of the image this backend is for

Returns:

a new RenderingBackend. If the AwtRenderingBackend can't be used a NoOpRenderingBackend is used instead.

getFontUtil

public static FontUtil getFontUtil()

Returns:

a new FontUtil. If the AwtFontUtil can't be used a NoOpFontUtil is used instead.

buildImageData

public static ImageData buildImageData(InputStream inputStream)
                                throws IOException

Parameters:

inputStream - the InputStream to read from

Returns:

a new ImageData object constructed from the given inputStream

Throws:

IOException - in case of error
