This Patent Application has received a **final rejection** by the US Patent Office.

The rejection was based in part on prior art found by Ask Patents community below! The main reference cited by the Patent Examiner in the rejection was found by Ask Patents.

An applicant has several ways to keep an application in this state alive. They include a request for continuing examination, which involves paying more fees and responding to the rejection. Appealing the rejection is another avenue. If nothing is done it will go abandoned six months from the final rejection.  


Thanks to the **YOU**, the Ask Patents community, overly-broad claims have at least been narrowed. [Follow @askpatents](https://twitter.com/AskPatents) to block more overly-broad patent applications.

   **TITLE: Scale factors for visual presentations**

- **Publication Number**: [US 20130063492 A1][2]
- **App Number**: [13/230445][3]  
- **Assignee**: Microsoft Corporation
- **Prior Art Cutoff Date**: Prior Art **predating** Sept 12, 2011
- **Availability for Challenge:** Open Until at least Sept 14, 2013

**Summary**: This application generates and display graphical elements based on *pixel density.* The invention selects a *scale factor* from a *scale factor set* that is within the *range* of the pixel density.

**Claim 1** requires, among other things:

> A method of generating, using a device having a processor, a presentation comprising elements to be displayed on a display component, the method comprising:

> - executing on the processor instructions configured to:

>  - identify a ***pixel density*** of the display component;

>  - for respective elements of the presentation:

>        - from a ***scale factor set***, select a ***scale factor*** having a ***pixel density range*** including the pixel density of the display component; and

>        - request the element to generate a scaled representation using the scale factor; and

>  - generate the presentation comprising the scaled representations of the elements.

**WHY IT MATTERS** - This application is similar to other resolution-independent scaling applications, patents, and implementations carried out in the industry.

**QUESTION** - Have you seen anything that was **published before 09/12/2011** that discusses (1) scale factor; (2) scale factor set; and (3) pixel density range in the manner described in claim 1?

If so, please submit evidence of that prior art as an answer below. Please submit only one piece of prior art per answer below. We welcome multiple prior art proposals from the same individual; please create separate answers for each one. This is so the community can vet each individual piece of prior art independently.
