How to find exact size for an arbitrary glyph in WPF?

阅读更多关于 How to find exact size for an arbitrary glyph in WPF?

问题 I need to find exact size for each character in an arbitrary font. The font is loaded using GlyphTypeface class. The problem is that I can access directly only width of a glyph using the AdvanceWidths property, but the height is the same for each characters and it is set to Height property. It seems that individual character height can be computed using a combination of Baseline, Height, XHeight, BottomSideBearings and TopSideBearings properties, but there is no documentation about real

Horizontal alignment of “large” labels is offset when using adj argument in text

阅读更多关于 Horizontal alignment of “large” labels is offset when using adj argument in text

问题 In text , the argument adj allows adjustment of the labels with respect to x and y . For example, adj values of (0, 1) means left-top alignment, i.e. the left, top corner of the label is placed at the given x , y coordinate. This works fine with the default character expansion cex = 1 . But when I want a larger label, created by increasing cex , the position of label is offset horizontally from the given coordinate and adj ustment. Here is a small example which demonstrates this: # a basic

Calculate the exact size of a font glyph

阅读更多关于 Calculate the exact size of a font glyph

问题 I need a way to find the exact size and position of a glyph relative to its bounding box. We're using D3.js to create an SVG with a heading, a smaller byline and a short body text. Pretty much this: Lorem ipsum Lorem ipsum dolor Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua As in this example, I need the text to be left-aligned regardless of font-size. The problem is that it is each lines bounding box that's aligned

Outline of a text as single line vector path

阅读更多关于 Outline of a text as single line vector path

问题 For an application I need to draw text/glyphs as a vector based path. Using GDI+ GraphicsPath and Graphics.DrawPath or WPF FormattedText and Geometry works fine and I get the output as shown in the first picture. But is it somehow possible to get letters as a single line path as shown in the second picture (shows an L). I'm glad if anyone has an idea. See this example. Using built-in function will always give you the path of a letter containing it's inner and outer borderline. Only the first

How To Print Glyph Elements in WinRT

阅读更多关于 How To Print Glyph Elements in WinRT

问题 I am trying to print a Canvas with Path, TextBlock and Glyph elements on it, however the Glyphs are excluded in the printed content. This is eerily similar to the exact same problem with Silverlight 5 Vector printing, for which I never found a resolution. Am I missing something or does the same problem exist in WinRT? As background, I would like to print an XPS document, but as WinRT cannot print one directly, I am creating a Canvas out of each page, which can then be fed to the WinRT

Unicode Glyph for Padlock

阅读更多关于 Unicode Glyph for Padlock

问题 I need to use a unicode character that looks like a padlock. It's for a button below a form that says "CopyLink __" with a padlock on it, to indicate that when they copy the link of the page they are on, the person going to the "copylink _" version of the page will not be able to modify the form. Anyway, I've looked around -- this page has a lot of miscellaneous unicode symbols, but after the the musical sharp note the rest of the symbols do not load. this link says that I should be able to

Text update slowing down app

I have a Hebrew calendar app where each day is a UserControl. I have 6 labels in that control for the English date, the Hebrew date, Jewish holidays and some other user-defined data. When scrolling, the labels' content changes as the date value for the UserControl goes up or down a week. The scrolling is noticeably slower than Microsoft Outlook Calendar, and profiling reveals that the part taking the longest is updating the label contents, which is not handled by my code. Is there some way I can make this go faster? MS Outlook seems to have a comparable number of text fields, and the scrolling

What do we use glyph for?

阅读更多关于 What do we use glyph for?

问题 What is a glyph and what do we use it for especially in context of silverlight and xaml? 回答1: Glyphs are a low-level depiction of a character to be drawn on-screen. A good article on them is available on MSDN: Introduction to the GlyphRun Object and Glyphs Element. Posting a link for you read, I think it is better than simply rehashing the information in my answer (it has pictures and links for further reading). 回答2: See the following MSDN article for info on Glyphs: http://msdn.microsoft.com

Extracting glyph-path information from ttf files

阅读更多关于 Extracting glyph-path information from ttf files

问题 I'm trying to figure out a way to extract the information encoded in ttf files. namely: The char-to-glyph table and the individual glyph path data. Does anyone have a good reference explaining the ttf file structure, or some other solution? Keep in mind that I'm not interested in any libraries that can do it for me either (unless they are open source and I can see how they are doing it). The "master" goal is to implement it in Javascript. Thanks! 回答1: Take a look at OpenType.js at http:/
