If the first portion of a word is an insertion that has been tracked with Redline, and the wordFor historical reasons, there are no less than three sets of values that deal with your vertical metrics.

Mac OS X Snow Leopard, affecting the leading and vertical position of the text, as well as any drop shadows applied to the text.

Fortunately, Glyphs does its best to calculate them based on the vertical metrics you enter for each of your masters: ascender, cap height, x-height and descender. Select or cancel selection of the active item.Hi, I am using Malwarebytes 4, but this morning the Browser Guard extension has started crashing,causing Chrome to freeze until I turn Browser Guard off.Unfortunately, all of these values relate to each other in a pretty complicated way. Ctrl+Up arrow key or Ctrl+Down arrow key. Go to the next or previous item without extending the selection. Shift+Up arrow key or Shift+Down arrow key.![]() typoDescender: the depth of the descenders in units (negative value) typoAscender: the height of the ascenders in units I have seen designers refer to them as OS/2 values, but that is a little imprecise, because the win values are also part of the OS/2 table. In the dark past of electronic typesetting, the TrueType/OpenType specifications used to stipulate that the span from typoAscender to typoDescender should be as large as the font’s UPM (usually 1000 or 2048). The UPM dogmaThere is one thing you need to watch out for, though: the ‘UPM dogma’. In that case, typoLineGap will be respected as well. In DTP apps, the line gap is set by the user, hence typoLineGap is ignored.Office software and browsers should prefer the typo values over win if the Use Typo Metrics parameter is set to yes. Windows supposedly uses these values to find the ideal parameters for layout thus we have a certain degree of artistic freedom.’The big layout apps, XPress and InDesign, use the typoAscender and typoDescender values to determine the offset of the first baseline in a text box and the minimum size of a text box below which the display of type is suppressed. winDescent: the bottom extremum of the font rendering box (positive value)Attention: whatever extends above or below these values, will likely be cut off when rendered by the Windows text engine. winAscent: the top extremum of the font rendering box OS/2 usWin (win)The win (or usWin) values are also part of the OS/2 table. These values should be set to provide default line spacing appropriate for the primary languages the font is designed to support.(Source: OS/2 sTypoAscender specification on Microsoft Typography)_Yet, the UPM dogma still plays a role in the (legacy) Adobe and Microsoft strategies discussed below. One of the proponents of letting go of the UPM dogma was Victor Gaultney from SIL, who wrote both Best Practice: Design Metrics and Best Practice: Line Metrics.In the meantime, the dogma was dropped altogether from the OpenType specification:It is not a general requirement that sTypoAscender - sTypoDescender be equal to unitsPerEm. It tells Office apps to prefer the OS/2 values over the win metrics. According to the MakeOTF User Guide, this bit was introduced ‘so that reflow of documents will happen less often than if Microsoft just changed the behaviour for all fonts.’All modern fonts should have this parameter. If you can safely ignore older (i.e., pre-2006) MS Office versions, you should add a Use Typo Metrics parameter to File > Font Info > Font. If checked, applications that respect this setting (in particular, versions of Microsoft Office since 2006) will prefer typoAscender, typoDescender, and typoLineGap over winAscent and winDescent for determining the vertical positioning.Technically, what it does is set bit 7 (‘don’t use Win line metrics’) of the fsSelection field in the OS/2 table. Use Typo MetricsThere is one more thing. For every master, highest and deepest points in all glyphs will be listed. So, usually, nothing you do in your font will exceed the win span.In order to find the highest and lowest points in your font, try the mekkablue script Test > Report Highest and Lowest Glyphs. If you find the correct display of underlines in Microsoft Word more important than proper linespacing, disable Use Typo Metrics, and follow one of the legacy strategies. If Use Typo Metrics is on, default underline values will be used instead. In other words, underlinePosition plus underlineThickness must be smaller than winDescent. Even if it is off, and if the underline does not fit above winDescent, it will be raised accordingly. Everyone else is entitled to consider this a problem of the past.Another problem is that, in Microsoft Office software, values for underlinePosition and underlineThickness are ignored when Use Typo Metrics is on. If you find yourself in the position of needing to support ancient software: Duh. But keep in mind that both of these strategies are outdated because they both adhere to the UPM dogma. They are handy to know because you may have to make your font compatible with legacy software. First, two historical methods, the Adobe and Microsoft strategies. Let me show you the most popular strategies for manually setting your vertical metrics. StrategiesWith the custom parameters listed above, you can override the automatic calculation and set the values manually. So it may be a good idea to use this method if your font has a low x-height (below half UPM). Font Info > Font > Custom Parameters: Use Typo Metrics = yesWith this strategy, the linegap tends towards the small end of the spectrum. hheaLineGap = winAscent + winDescent – UPM Legacy: the Adobe strategyThe hhea values are synchronized with the OS/2 values. My passport for mac wont let me add files−200), you put the rest (800) into typoAscender. You could put the depth of the descender into typoDescender (e.g. typoLineGap = winAscent + winDescent – UPMFor the rest, as already mentioned above, the span from typoAscender to typoDescender must add up to your UPM value (usually 1000). hheaDescender = − winDescent (negative value) Disadvantages: differences between Mac and Win display accents on caps may be cut off in office apps.The hhea values are synchronized with win values, thus to the BBox maxima. Disadvantage: differences between Mac apps and layout apps (XPress, InDesign), and default leading may appear to be too much.We support and recommend the webfont strategy. Advantages: better synchronization of font display between Win and Mac apps accents are not cut off in Mac apps because winAscent tends to be higher than typoAscender. So it may be a good idea to use this way if your font has a large x-height (above half UPM). Subtract your UPM value from that sum and put the result into typoLineGap.With this strategy, the linegap tends towards the large end of the spectrum. That’s right, the line gap is distributed evenly above and below the line. Similarly, the distance from the very last line of text inside an HTML element to the bottom edge of the same element is determined by hheaDescender plus half of hheaLineGap. When text is placed inside an HTML element such as or , these browsers will add hheaAscender plus half of hheaLineGap, and use this to calculate the position of the first baseline in respect to the top edge of the HTML element.
