摘要： Images that are contained within documents are compressed to reduce the file size of the document. The compression may occur such that compression steps occur to the image automatically. The compression steps performed are determined based on the information available about the images in a document. The information is used to determine whether or not the image should be compressed as well as what compression method is used.

摘要： Transparent content and opaque content that is contained within a document is treated differently for printing. The transparent content within a document is rasterized and stored in a system-managed bitmap before printing. While rasterization is effective for maintaining visual fidelity of transparent content it can lead to large spool files and poor performance if excessively performed. In order to help optimize the performance of output devices, the transparent content within the document is rasterized and the opaque vector content within the document is drawn into a metafile before printing. The metafile is replayed onto the printer and into the bitmap such that the opaque content can be blended with the rasterized transparent layers that are contained within the bitmap. The bitmap is then drawn on the printer.
