the provided data is able to be rasterized by the
implementation . The implementation should take care of
this feature as well as setting the default image size in
pixel within the given output parameter . < / p >
@ param DataStream
The input stream of data that should be rasterized
@ param DPI_X
The horizontal resolution of the callers device in pixel per inch . This
value is needed to calculate the correct dimensions of the graphic to be
rasterized . If a value of < value > 0 < / value > is given , a horizontal default
resolution of 72 DPI is used .
@ param DPI_Y
The vertical resolution of the callers device in pixel per inch . This
value is needed to calculate the correct dimensions of the graphic to be
rasterized . If a value of < value > 0 < / value > is given , a vertical default
resolution of 72 DPI is used .
@ param DefaultSizePixel
The default rendering size in pixel of the underlying graphics
data may be available after the call via this output parameter .
In case no default size can be determined during initialization ,
a default pixel size of 0 , 0 is returned . In this case , the caller
needs to assume a default pixel size , appropriate for the calling
context .
@ returns
A boolean value indicating if rasterizing of the given data is
possible at all and if the initialization process happened
successfully .

@ param Width
The width in pixel of the graphic to be rasterized .
This parameter is used without taking other transformation
values into account .
@ param Height
The height in pixel of the graphic to be rasterized .
This parameter is used without taking other transformation
values into account .
@ param RotateAngle
The rotation angle of the graphic to be rasterized .
This parameter is used without taking other transformation
values into account . The rotation is applied after scaling
and shearing the original image .
@ param ShearAngle_X
The horizontal shear angle of the graphic to be rasterized .
This parameter is used without taking other transformation
values into account . The shearing is applied after scaling
and before rotation of the image .
@ param ShearAngle_Y
The vertical shear angle of the graphic to be rasterized .
This parameter is used without taking other transformation
values into account . The shearing is applied after scaling
and before rotation of the image .
@ param RasterizeProperties
Additional properties for special needs ( undefined by now )
@ returns com : : sun : : star : : graphic : : XGraphic
