Transparency printing
First Claim
1. A computer-implemented method for transparency printing, comprising:
- accessing a document that comprises transparent content and opaque content;
determining raster content to rasterize to a bitmap;
wherein the raster content includes at least a portion of the transparent content and a portion of the opaque content;
rasterizing the raster content to the bitmap;
printing remaining content to a metafile; and
playing the metafile onto an output device and to the bitmap such that the remaining content that is contained within the metafile can be blended with the raster content that is contained within the bitmap.

Abstract
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.

9. A computer-readable medium having computer-executable instructions for printing a document containing transparent content and opaque content, comprising:
-
determining content to rasterize to a bitmap;
wherein the content includes a majority of the transparent content and the opaque content that is covered by the transparent content;
rasterizing the content to the bitmap;
printing remaining content to a metafile; and
playing the metafile onto an output device and to the bitmap such that the remaining content that is contained within the metafile is blended with the content that has been rasterized to the bitmap. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for printing, comprising:
-
an application configured to output a document that includes transparent objects and opaque objects; and
a print manager coupled to the application and that is configured to perform actions;
comprising;
determining a portion of opaque content to rasterize to a bitmap;
rasterizing the opaque content and transparent content to the bitmap;
printing remaining portion of the opaque content to a metafile; and
playing the metafile onto an output device and to the bitmap such that the remaining content that is contained within the metafile is blended with the content that has been rasterized to the bitmap. - View Dependent Claims (16, 17, 18, 19, 20)
