由 爷，独闯天下 提交于 2021-02-07 11:52:22

Syntax: \underset{<constraints>}{\operatorname{<argmax or argmin>}} Example: $\underset{c\in C}{\operatorname{argmax}}$ 回答2: This worked for me when using pandoc

问题 When developing a web page/application, I often don't have all the data right upfront. Sometimes I need to put dummy text and images in places to get the overall feel of how its going to look. For dummy text, I can use Lorem Ipsum to generate such junk text. But how can I do something similar with images? 回答1: Similar to Lorem Ipsum, theres this one: Lorem Pixel This generates placeholder images for your html if the specified size. The url of the site follows the pattern : http://lorempixel

问题 I'm trying to "render" text outlines in WPF to from a rich text source. In many cases, the TextFormatter class does what I want, as in this snippet: var tf = new Typeface( new System.Windows.Media.FontFamily("Pericles"), FontStyles.Normal, FontWeights.Normal, new FontStretch() ); var brush = new SolidColorBrush(Colors.Black); var ftext = new FormattedText( text, CultureInfo.CurrentCulture, FlowDirection.LeftToRight, tf, 72, brush ); var geometry = ftext.BuildGeometry(new Point()); Here, I
