ABSTRACT:
Methods, systems, and programming for producing and displaying a scaled-down representation of subpixel-optimized images and digital content including such images that is represented by a mark-up language. Some embodiments display the text in such digital content using a different subpixel optimization than that used for the images. Others produce the subpixel-optimized images by calculating the luminosity of a subpixel as a function of the length of a plurality of coverage lines within a window in a source image corresponding to the subpixel that is covered by source image pixels having the subpixel's color. Some embodiments calculate the luminosity of a subpixel in such a subpixel-optimized image as a function both of the average luminosity of pixels in the subpixel's source image window and as a function of any color balancing distribution between resulting subpixel luminosities necessary to reduce color imbalance.

Edward Porter, “Screen Shot of Three Microsoft-Internet Explorer Windows Showing Same Portion of Web Page with Different Layouts”, created Sep. 16, 2005 on Mr. Porter's computer by opening three separate IE windows showing same web sites and manually varying window width and font size. It is the applicant's belief that IE's ability to alther the layout of a web page by altering window width and font size predates 2000. 1 page.
Edward Porter, “Screen Shot of Microsoft Word Displaying Portion of Text at Two Different Displayed Font Sizes”, created on Sep. 16, 2005 on Mr. Porters computer by using the split box to open two panes in an MS Word view, scrolling the bottom pane so it showed same text as top pane, and increasing the magnification in the bottom pane while in normal view so the text in the bottom pain would re-flow across line boundaries. It is the applicants belief this capability predates 2000. 1 page.
