This invention structurally and methodologically relates to the speedy, efficient and high-quality handling of an image-only file in a PDF data stream which is en route to a printer. Such a file might typically have been initiated by a document scanning operation aimed at sending that document to a recipient printer via e-mail and the Internet. Other transit modalities are, of course, possible, and the present invention is independent of all such modalities.
Typical PDF conventional, or standard, data-handling protocols and environments are rich with capabilities for many tasks involved with managing, manipulating and conveying PDF data files, but are notably less than fully satisfactory in certain ways with regard to the handling of image-only PDF files. Handling and processing of such files is often discomfortingly slow and tedious and end printed-image results often result as image-quality disappointments.
The present invention tackles these less-than-satisfactory, conventional, PDF image-file handling image-only issues, and effectively does so by monitoring an en route PDF data stream to detect the presence (or presences) of any truly PDF image-only file (or files) in that stream.
According to the invention, such an image-only file is functionally deflected and channeled away from conventional, downstream, PDF handling protocols and environments, and is, instead, fed dedicatedly to a new PDF image-only-committed pipeline, wherein it is treated to speedy and efficient handling, and passing along for printing, with printed results meeting very high standards of printed-image quality.
The various features and advantages of the invention will now shortly become very apparent as the detailed description which follows is read in conjunction with the accompanying drawings.
Turning now to the drawings, and referring first of all to
If No, such as will be the case with respect to files 12c, 12d and 12e, such a file is steered via route 14a to appropriate, conventional PDF handling protocols and environments which are represented in
From pipeline 18, a speedily and efficiently handled PDF image-only file, “rendered for printing” readiness, is output via path 20 for downstream transit toward selected printing structure (not shown).
Looking now into the preferred and best mode construction proposed for pipeline 18, such is illustrated collectively in
Thus,
As is true with regard to what is shown in
The invention is thus fully described systemically in its preferred and best mode embodiment. Further, the preferred and best mode manner (methodology) of its, practice and operation are also clearly evident from the figure illustrations provided, and from their respective labeled descriptions and the illustrated interconnections.
Uniquely, the system and methodology of this invention monitor a PDF data stream which is en route ultimately to printing, look specifically for any PDF image-only file contained in that data stream, and on finding such, deflect and channel it for carefully expedited, efficient handily by the novel, dedicated, PDF image-only pipeline proposed and provided by the invention.
Having thus presented the invention, we appreciate that variations and modifications may be made without departing from the spirit of the invention.
