Universal reader

A computer program product for embedding rich content of associated with a document in an image, the computer program product comprising:

• a computer readable medium;
• program code stored on the computer readable medium for generating a static image of the document;
• program code stored on the computer readable medium for determining whether an amount of memory required by the rich content exceeds a threshold amount, wherein the rich content comprises a rich content version of the document that retains document functionality;
• program code stored on the computer readable medium for responsive to a determination that the amount of memory associated with the rich content does not exceed the threshold amount, encoding the rich content into a single content block according to an image format to form a rich content block;
• and
• program code stored on the computer readable medium for inserting the rich content block into an arbitrary storage location associated with the image, wherein the static image of the document is displayed when the image is opened by a computing device in an absence of an application associated with the rich content of the document, and wherein the rich content is displayed when the image is opened by the computing device in a presence of the application associated with the rich content of the document.

A computer implemented method for storing rich content of a document in an image, the method comprising:

• generating a static image of the document;
• determining whether an amount of memory required by the rich content exceeds a threshold amount, wherein the rich content comprises a rich content version of the document that retains document functionality, and wherein the rich content further comprises graphical and audiovisual content;
• responsive to a determination that the amount of memory associated with the rich content does not exceed the threshold amount, encoding the rich content into a single content block according to a document format;
• responsive to a determination that the amount of memory associated with the rich content does exceed the threshold amount, encoding the rich content into a plurality of content blocks according to the image format to form a set of split blocks;
• generating a sequence number for each split block in the set of split blocks, wherein the each split block in the set of split blocks is recombined in accordance with the sequence number;
• selecting an image format in a plurality of image formats to form a selected image format;
• storing the rich content block in the selected image format in the image, wherein rich content blocks are stored in multiple document formats within the image;
• inserting content blocks, wherein the content blocks are composed of either the rich content block or the set of split blocks, into an arbitrary storage location of the image, wherein the content blocks are divided into a set of rich content blocks, wherein the set of rich content blocks are divided into at least a first rich content block and a second rich content block, wherein the first rich content block is associated with a first application corresponding to the image format associated with the first rich content block and the second rich content block is associated with the second application corresponding to the image format associated with the second rich content block;
• responsive to opening the image, by the computing device, in a presence of the first application corresponding to the document, displaying the rich content associated with the first rich content block;
• responsive to opening the image, by the computing device, in a presence of the second application corresponding to the document, displaying the rich content associated with the second rich content block;
• responsive to opening the image, by the computing device, in an absence of the first application and an absence of the second application, displaying the static image of the document.
