IE 9 does not use sub-pixel antialiasing under certain conditions

[Original title: IE 9 text renders very poorly; is there a workaround? ) IE 9 is rendering the text in my application very poorly. The problem is not in my monitor's Clear Type settings, since IE 9 in compatibility mode, Firefox, and Chrome all render text nicely. Here's a side-by-side comparison of how the text is rendered with IE 9, IE 9 in compatibility mode, and Chrome: I tried applying this answer , but it doesn't seem to apply to anything after IE 7. Does anybody know of any workarounds we can apply to our site to fix IE 9's bad text rendering? Edit: I've boiled down the problem page to

problematic Moire pattern in image produced with gnuplot pm3d and pdf output

…衆ロ難τιáo~ 提交于 2019-11-27 05:31:58
I'm plotting data using the command files discussed here: gnuplot contour line color: set style line and set linetype not working I want to provide different output options. PNG works well, as does the wxt terminal, however, these have fixed resolution, e.g. when I "zoom in" on the plot it gets grainier. If I use pdf or pdfcairo for the terminal, the resulting file has a Moire pattern. The region in the image over which the Moire pattern is observed can be reduced by using increasing amounts of interpolation in the pm3d command. There are lots of points in the data set in the radial direction,

Faking Subpixel Antialiasing on Text with Core Animation

♀尐吖头ヾ 提交于 2019-11-27 05:24:48
问题 For anyone working on a project with Core Animation layer-backed views, it's unfortunately obvious that subpixel antialiasing (text smoothing) is disabled for text not rendered on a pre-set opaque background. Now, for people who are able to set opaque backgrounds for their text (either with a setBackgroundColor: call or the equivalent setting in Interface Builder), this issue doesn't present too much of a problem. For others, though, who have absolutely no way to work around it, it's not

PHP Imagick PDF conversion Text aliasing

為{幸葍}努か 提交于 2019-11-27 04:54:23
问题 I'm having some troubles converting PDF files to JPEG with Imagick in PHP. After a lot of research, i'm able to convert CMYK pdf to RGB jpg without weird color conversion… but now, my last issue : the text is completely aliased ! The text from the original PDF file is not vectorized. An example : Here is the code : $imagick = new Imagick(); $imagick->setResolution(150,150); $imagick->readImage('file.pdf'); //CMYK PROFILE $icc = file_get_contents('USWebCoatedSWOP.icc'); $imagick->profileImage(

Anti-aliasing on rotated div with border image in firefox

心不动则不痛 提交于 2019-11-27 04:43:09
问题 I have a div rotated 45 degrees, with a border image on it. In chrome and safari, it renders fine. In firefox, nasty anti aliasing lines appear around the edge of the rotated div, between the edge of it and its border image. Here's the simple HTML: <div class="container"> <div class="corner"> </div> </div> and here's the CSS: .container { margin: auto; width: 400px; height: 400px; background-color: black; outline: 1px solid #333333; position: relative; overflow: hidden; } .corner { position:

How to force anti-aliasing in JavaFX fonts?

徘徊边缘 提交于 2019-11-27 04:14:13
While testing the GUI of my JavaFX 8 application, I noticed that some labels are not displaying anti-aliased text. After some googling and struggling, I found out a very annoying thing that is happening. The anti-aliasing is being applied only on labels which font size is greater than 80px. Here is an example comparing JavaFX and Swing applications with AA applied: Sample code: https://gist.github.com/anonymous/be60bb89181376ff12aa Is there a way to force the AA in all font sizes? Does this happen to you too? I searched for a similar bug on JavaFX Jira , but nobody is complaining about that so

Does CSS support text anti-aliasing such as “crisp, sharp etc” yet?

送分小仙女□ 提交于 2019-11-27 03:12:45
问题 I have some text in Photoshop & it's set to "crisp". When I put it on my site it doesn't quite look the same. Does anything exist in CSS yet that I can use to make it crisp? Or not? Or do you have any suggestions to achieve a similar effect? 回答1: Not only is it not possible, but different browsers on the market enforce different antialiasing settings, meaning that you can't get consistent results, even if they are not what you want. For a good article on how the various browsers deal with

iPhone: CALayer + rotate in 3D + antialias?

邮差的信 提交于 2019-11-27 02:29:53
问题 An iPhone SDK question: I'm drawing a UIImageView on the screen. I've rotated it in 3D and provided a bit of perspective, so the image looks like it's pointing into the screen at an angle. That all works fine. Now the problem is the edges of the resulting picture don't seem to be antialiased at all. Anybody know how to make it so? Essentially, I'm implementing my own version of CoverFlow (yeah yeah, design patent blah blah) using quartz 3d transformations to do everything. It works fine,

Disable Cleartype (text anti-aliasing) in IE9

久未见 提交于 2019-11-27 01:37:25
问题 It's well documented (e.g. here) that IE9 ignores the OS-wide settings for font smoothing (aka anti-aliasing). Even if font-smoothing and ClearType are disabled in Windows, IE still shows anti-aliased fonts, which some users struggle to read, especially at small font sizes. How can I disable all font anti-aliasing (ClearType or otherwise) in IE9? More details: Our company builds a web application which uses a lot of small fonts. With the release of IE9, some of our users have complained that

Poor anti-aliasing of text drawn on Canvas

落爺英雄遲暮 提交于 2019-11-26 23:16:48
问题 I'm drawing text on Canvas, and am disappointed with the quality of antialiasing. As far as I've been able to determine, browsers don't do subpixel antialising of text on Canvas. Is this accurate? This is particularly noticeable on iPhone and Android, where the resulting text isn't as crisp as text rendered by other DOM elements. Any suggestions for high quality text out put on Canvas?
