Class MathGraphic4a

java.lang.Object
  org.foray.graphic.Graphic4a
      org.foray.graphic.MathGraphic4a

All Implemented Interfaces:

org.axsl.graphic.Graphic, org.axsl.graphic.MathGraphic

public class MathGraphic4a
extends Graphic4a
implements org.axsl.graphic.MathGraphic

A MathML Graphic. The current approach to handling MathML is that it is treated internally as SVG.

Constructor Detail

MathGraphic4a

public MathGraphic4a(GraphicServer4a server,
                     URL url,
                     BufferedInputStream bis)

Constructor for the case of an unparsed URL.

Parameters:

server - The parent graphic server.

url - The URL which contains the graphic content.

bis - The reusable input stream containing the bytes from url.

MathGraphic4a

public MathGraphic4a(GraphicServer4a server,
                     org.w3c.dom.mathml.MathMLDocument mathDocument)
              throws org.axsl.graphic.GraphicException

Constructor for the case of a parsed MathMLDocument.

Parameters:

server - The parent graphic server.

mathDocument - The parsed MathMLDocument. This must not be null.

Throws:

org.axsl.graphic.GraphicException - For error creating an SVG for the MathML document.

Method Detail

loadImage

public void loadImage()
               throws org.axsl.graphic.GraphicException

Description copied from class: Graphic4a

Load image data and initialize its properties. Subclasses need to implement this method.

Specified by:

loadImage in class Graphic4a

Throws:

org.axsl.graphic.GraphicException - an error occured during loading

getMathDocument

public org.w3c.dom.mathml.MathMLDocument getMathDocument()
                                                  throws org.axsl.graphic.GraphicException

Specified by:

getMathDocument in interface org.axsl.graphic.MathGraphic

Throws:

org.axsl.graphic.GraphicException

getGraphicType

public org.axsl.graphic.Graphic.Type getGraphicType()

Specified by:

getGraphicType in interface org.axsl.graphic.Graphic

getCompressionType

public org.axsl.graphic.Graphic.Compression getCompressionType()

Specified by:

getCompressionType in interface org.axsl.graphic.Graphic

getMimeType

public String getMimeType()

Specified by:

getMimeType in interface org.axsl.graphic.Graphic

parseBasics

public void parseBasics()
                 throws IOException

Description copied from class: Graphic4a

This abstract method is implemented in subclasses to initiate parsing of enough of the image for it to be used in layout. This method is responsible to:

1. store the image's intrinsic width in Graphic.pixelWidth()
2. store the image's intrinsic height in Graphic.pixelHeight()

The housekeeping work related to resetting the buffer, handling IOExceptions, and managing whether this method should be run are handled elsewhere. In short, this method does not need to address the details handled there.

Specified by:

parseBasics in class Graphic4a

Throws:

IOException - For IO errors during reading of the file.

getName

public String getName()

Specified by:

getName in interface org.axsl.graphic.Graphic

getRawSamples

public byte[] getRawSamples()
                     throws org.axsl.graphic.GraphicException

Specified by:

getRawSamples in interface org.axsl.graphic.Graphic

Throws:

org.axsl.graphic.GraphicException

absoluteWidthReal

                      throws org.axsl.graphic.GraphicException

Description copied from class: Graphic4a

Returns the absolute width, in millipoints, of the graphic.

Specified by:

absoluteWidthReal in class Graphic4a

Returns:

The absolute width, in millipoints, of this graphic, if known. If not known, returns -1.

Throws:

org.axsl.graphic.GraphicException - For errors during reading of image file.

absoluteHeightReal

public int absoluteHeightReal()
                       throws org.axsl.graphic.GraphicException
