Comments[edit]

This article is extremely dated. There is no coverage of DirectWrite (Windows) or how the Windows Presentation Foundation (WPF) rasterises text. Moreover, as of May 2010 all TrueType related patents have expired. This makes it possible for FreeType to enable bytecode hinting without being patent encumbered. I am unconvinced that the D-Type stuff is relevant --- do any applications actually use it? As the author of "A Treatise on Font Rasterisation With an Emphasis on Free Software" (see citations/references for a link) I am happy to license the article --- along with all associated media -- under the "Creative Commons Attribution-ShareAlike 3.0 Unported" license if it will help.

The image "Rasterization with subpixel rendering for an RGB flat panel display" should show the actual RGB pixels (since it's zoomed in and can be done) to better show people the effect. -- I suggest removing the commercials, along with their annoying trademark and registered signs.


Subpixel rendering does not necessarily mean that hinting is used. Rather, this depends on the implementation. I think this should be made clear by showing the samples both with and without hinting.

I changed the page to only show hinted anti-aliased text since the other two samples are hinted. The old image is still on Wikipedia, though: [[Image:Rasterization-antialiasing-without-hinting.png]] --Crashie 16:07, 22 March 2007 (UTC)

There is no info about anti-alias in Linux, since it support as well both anti-alias and subpixel rendering.

Fair use rationale for Image:Rasterization-simple.png[edit]

Nuvola apps important.svg

Image:Rasterization-simple.png is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

Currently used rasterization systems[edit]

The article states "RISC OS has featured font anti-aliasing since 1990." There is some talk about RISC OS regarding the claim of it being "one of the first operating systems to include [Sub-pixel positioning anti-aliasing"]. Are any dates available for the other systems? --trevj (talk) 15:14, 14 January 2011 (UTC)

Break article into sections[edit]

I ran into the term "bi-level rendering" in the Segoe article. This article contains the only relevant discussion regarding bi-level rendering I could find in Wikipedia (though it doesn't mention the specific term). It would be nice to be able to link "bi-level rendering" to the appropriate section in this article, but that can't be done until this article is broken into sections. Can someone with better editorial skills than myself break the article up, and maybe even mention "bi-level rendering" under the section discussing aliased text (or non-anti-aliased text)?
