ABSTRACT:
An integrated graphics manipulation program that employs a technique of rasterizing EPS files during import and using this rasterized version as a "proxy image" for display of an on-screen image. When a document containing a EPS data is printed to a PS printer, the actual EPS data is sent to the printer. If the document is printed to a non-PS printer, the rasterized proxy representation of the EPS data is used. The effect that this has is that the on-screen representation of the EPS data (the rasterized proxy image) is a high quality representation of the EPS data. The original EPS data may be re-rasterized at a new scale to generate a new proxy image whenever a user resizes the proxy image on the display. This results in an on-screen representation that more closely resembles the printed output to a PS printer. The EPS data also may be re-rasterized at a new scale to generate a new proxy image whenever a user zooms in to or out of a document. This would give the desired effect of reducing aliasing that occurs when a static rasterized image is zoomed. With this approach, the EPS proxy image becomes a dynamic on-screen representation of the original EPS data. The preferred "native" file format for any program implementing the invention remains vector-based, so that the highest quality image is always available regardless of printer type.
