Abstract
Disclosed is a method and system for checking and identifying images and other document components that may not be suitably rendered by an output device or process. The method employs a dual-mode analysis of visual image attributes to determine an aggregate confidence while also checking individual image attributes, to determine whether image content requires adjustment prior to being printed or rendered.
Claims19
A method for processing a document stored in memory for rendering, comprising:
- analyzing, using a processor, at least a portion of the content of the document stored in memory, prior to rendering, for at least one visual image attribute;
- determining, based upon the analyzing, a confidence that the rendering of the document will produce a desirable output;
- and
- based upon the confidence, carrying out an adjustment of the document stored in memory;
- and rendering an adjusted document.
A method for analyzing a document stored in memory prior to rendering to determine a confidence that the document will be correctly rendered, comprising:
- analyzing, using a processor, at least a portion of the content of the document stored in memory prior to rendering, and for each image identified in the document characterizing a plurality of visual image attributes;
- determining an aggregate confidence that rendering of the document will produce a desirable output, including
- (a) comparing the visual image attributes as analyzed to at least a first boundary condition associated with each attribute, such that each comparison produces a result that indicates whether the attribute meets the first boundary condition, and
- (b) aggregating the results from the step of comparing the attributes to the associated first boundary conditions, and taking the aggregate as an aggregate confidence;
- using the processor, comparing the visual image attributes as analyzed to at least a second boundary condition associated with each attribute, such that each comparison produces a result that indicates whether the attribute meets the second boundary condition;
- and
- if the aggregate confidence and comparison of visual image attributes indicates the attributes meet all of the second boundary conditions, rendering the document;
- and otherwise
- carrying out an adjustment of the document stored in memory prior to rendering an adjusted document.
A system for processing a document to determine if the document will produce a desired result, comprising:
- a port for receiving document data, including image data that represents an input digital image;
- memory for storing said image data;
- a processor, capable of accessing said memory, for carrying out an analysis of at least one visual attribute of the image, said processor further determining, based upon the analysis, a confidence that the rendering of the image data will produce a desirable output;
- an image adjustment system, responsive to the confidence, for carrying out an adjustment of the image;
- and
- an output device for rendering the document.
