Orientation-dependent processing of input files by an electronic device

An electronic device, comprising:

• a display screen;
• and
• a processor in communication with the display screen and configured to execute computer readable instructions stored in a memory to:
• obtain a structured document that includes a plurality of content elements;
• after obtaining the structured document:
• prepare a first rendered document having the plurality of content elements;
• compute a score for each of the plurality of content elements;
• select a subset of said plurality of content elements from the structured document by selecting those ones of said plurality of content elements having a score at or above a threshold, said score being determined based on at least one factor selected from the group consisting of:
• word count, character count, and link density, wherein the link density is based on a count of hyperlinks appearing in the content element in the obtained structured document, the subset excluding one or more of the content elements that are advertisements;
• prepare a second rendered document having said subset of said plurality of content elements, the second rendered document being a reader-style rendered document having fewer advertisements than the first rendered document;
• output the first rendered document to the display screen while the display screen is in a landscape orientation;
• detect a change in orientation of the display screen to a portrait orientation;
• and
• in response to said detecting, output the second rendered document to the display screen.

A method in portable electronic device having a display screen, the method comprising:

• obtaining a structured document that includes an article content portion, wherein the structured document further includes at least one style directive associated with the article content portion, the at least one style directive not being associated with a particular orientation of the display screen;
• preparing a first rendered document based upon the article content portion in accordance with said at least one style directive included with the structured document;
• preparing a second rendered document based upon the article content portion in accordance with a locally configured style directive, the locally configured style directive not being included in the structured document;
• outputting the first rendered document to the display screen while the display screen is in a landscape orientation;
• detecting a change in orientation of the display screen to a portrait orientation;
• and
• in response to said detecting, outputting the second rendered document to the display screen,
• wherein the structured document includes a plurality of content elements, and the second rendered document is based upon only a subset of the plurality of content elements that includes the article content portion, and wherein the second rendered document is a reader-style rendered document that includes fewer advertisements than the first rendered document.

A method at an electronic device for rendering structured documents for display, the method comprising:

• while a display screen of the electronic device is in a first orientation, rendering a structured document for display, the structured document including a plurality of content elements each having corresponding content, by generating a model including a hierarchical arrangement of the plurality of content elements and applying to the model said corresponding content and any style directives included with the structured document for said content elements to provide a rendered structured document, the style directives included with the structured document not being associated with a particular orientation of the display screen;
• outputting said rendered structured document to a display screen of the electronic device;
• while said rendered structured document is being displayed at the display screen, detecting a change in orientation of the display screen to a second orientation;
• further rendering the structured document for display by:
• identifying a subset of said plurality of content elements, the subset excluding one or more of the content elements that are advertisements and that were included in the structured document when the electronic device was in the first orientation;
• altering the model previously generated to include only those ones of the subset of said plurality of content elements;
• and
• applying to the model thus altered any corresponding content to provide a further rendered structured document, the rendered document being a reader-style document having fewer advertisements than the first rendered document;
• and
• outputting the further rendered structured document to the display screen in response to said detecting.
