Constructor Detail

EPSGraphic

public EPSGraphic(GraphicServer4a server,
                  URL url,
                  BufferedInputStream bis,
                  boolean isASCII)

Constructor.

Parameters:

server - The parent graphic server.

url - The URL which contains the graphic content.

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

isASCII - Indicates whether this file format is ASCII (true) or binary (false).

Method Detail

getName

public String getName()

Specified by:

getName in interface org.axsl.graphic.Graphic

loadImage

protected 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

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

protected 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.

getContent

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

Specified by:

getContent in interface org.axsl.graphic.Graphic

Overrides:

getContent in class Graphic4a

Throws:

org.axsl.graphic.GraphicException

getPreview

public byte[] getPreview()

Returns the embedded preview.

Returns:

The embedded preview, or null if there is no preview.

getBoundingBox

public org.axsl.ps.PsBoundingBox getBoundingBox()

Specified by:

getBoundingBox in interface org.axsl.graphic.EpsGraphic

getRawSamples

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

Specified by:

getRawSamples in interface org.axsl.graphic.Graphic

Throws:

org.axsl.graphic.GraphicException

absoluteWidthReal

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

Description copied from class: Graphic4a

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

Description copied from class: Graphic4a

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

Specified by:
