Constructor Detail

BMPGraphic

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

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.

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

getGraphicType

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

getCompressionType

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

getMimeType

public String getMimeType()

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()

getRawSamples

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

Throws:

org.axsl.graphic.GraphicException

absoluteWidthReal

public int 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

Description copied from class: Graphic4a

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

Specified by:

absoluteHeightReal in class Graphic4a

Returns:

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

Throws:

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