Method Detail

getCompressionType

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

Throws:

org.axsl.graphic.GraphicException

getGraphicType

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

getMimeType

public String getMimeType()

getName

public String getName()

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.

loadImage

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

Load the original TIFF data. This loads only strip 1 of the original TIFF data.

Specified by:

loadImage in class Graphic4a

Throws:

org.axsl.graphic.GraphicException - For IO Errors.

getStripCount

public int getStripCount()

Return the strip count.

Returns:

the stripCount.

getRawSamples

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

Throws:

org.axsl.graphic.GraphicException

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

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.
