US 10,885,266 B2 · Preserving semantic information in document conversion via color codes

Abstract

The present disclosure is directed toward systems and methods for maintaining semantic information in a document from a web page. For example, one or more embodiments described herein encode unique colors into an HTML DOM associated with a web page prior to passing the HTML DOM through an existing rendering engine. In response to receiving a color-coded graphical objects representative of the HTML DOM, systems and method described herein apply the original semantic attributes of the web page into the graphical objects based on the unique color encoding.

Claims20

Dependent claims

In a digital environment for converting digital documents from one format to another format, a computer-implemented method comprising:

receive an indication of a web page to convert to a portable document format (PDF);
access a mapping that associates a unique color code with attributes of the web page;
receive a modified data object model for the web page that includes the unique color code in place of an original color code associated with at least one node;
generate, by a rendering engine, a graphical object color coded with the unique color code;
generate structural constructs from the graphical object color coded with the unique color code that includes the original color code and the attributes of the web page;
and
generate, based on the structural constructs, a PDF document of the web page having the attributes and an original color of the web page.

4 more elements

A system comprising:

one or more computer processors configured to cause the system to:
access a mapping that associates unique color codes with attributes of a web page;
access a modified data object model for the web page that includes the unique color codes in place of original color codes associated with nodes;
generate, by a rendering engine, graphical objects color coded with the unique color codes;
generate portable document format (PDF) graphical constructs and PDF structural constructs from the graphical objects color coded with the unique color codes, the PDF structural constructs comprising the attributes and original colors associated with the original color codes;
and
generate, from the PDF graphical constructs and PDF structural constructs, a PDF document of the web page having the attributes and original color of the web page.

4 more elements

A non-transitory computer readable storage medium comprising instructions that, when executed by at least one processor, cause a computing device to:

parse a data object model associated with a web page to extract attributes associated with at least one node of the data object model, the at least one node corresponding to a display element of the web page having an original color;
generate a mapping that associates a unique color code with the extracted attributes of the at least one node of the data object model;
and
generate a modified data object model by replacing, within the data object model associated with the web page, an original color code associated with the at least one node with the unique color code.
