This method could also be used to determine, if
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.
Parameter DataStream
The input stream of data that should be rasterized
Parameter 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 0 is given, a horizontal default
resolution of 72 DPI is used.
Parameter 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 0 is given, a vertical default
resolution of 72 DPI is used.
Parameter 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.
Rasterizing the initialized data into a XGraphic container.
The XGraphic container will contain a pixel
type graphic after a successful rasterization process
In case of any fault during the rasterization process,
the XGraphic container will be empty afterwards and
the method will return false
Parameter Width
The width in pixel of the graphic to be rasterized.
This parameter is used without taking other transformation
values into account.
Parameter Height
The height in pixel of the graphic to be rasterized.
This parameter is used without taking other transformation
values into account.
Parameter 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.
Parameter ShearXAngle
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.
Parameter ShearYAngle
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.
Parameter RasterizeProperties
Additional properties for special needs (undefined by now)
Parameter Graphic
An interface to a graphic container into which the given data
should be rasterized.
Returns
com::sun::star::graphic::XGraphic
An interface to a graphic container that holds the rasterized pixel data
