If no explicit size or resolution option settings are given, Rasterize will rasterize g at the size and resolution it would normally be displayed in a notebook.
Rasterize yields , where w is the overall width in pixels of the raster, and h is its overall height.
Rasterize yields , where w is the overall width, h is the overall height, and dh is the offset of the baseline of the contents of g from the bottom of its bounding box.
Rasters generated by Rasterize can vary slightly from one computer system to another, mainly as a result of different fonts and anti-aliasing procedures.
The results from Rasterize can depend on details of font metrics, which generally differ between different computer systems.
Rasterize gives a list of rules of the form , where each rule is associated with an annotation of the form Annotation in g. The give pixel positions in the form , where y coordinates run from bottom to top, as in Graphics.
