+
+        @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 Height
+            The height in pixel of the graphic to be rasterized.

+            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.
