阅读更多关于 SVG for print with scale

问题 I have an SVG file representing a flat in my browser and I need to print the output in a specific scale. I'm using SVG.js to manipulate the SVG content but I can't find a combination of correct viewport viewbox setup to meet my needs. What I know is the SVG source file size. Via the x and y coordinates I calculated a distance to find the correct "screen scale" to match 1cm on the plan with a pixel number. For printing I need to respect "specific scales" for example 1/50. So I tried to get the

问题 I'm using SVG to draw in a HTML page different shapes. These different shapes are retrieved from geometry objects of a spatial database in Microsoft Sql Server. The problem I'm facing is that the system of coords (Svg and Microsoft Sql Server) is different. 0,0 begins in Svg on the top left corner, whereas in Microsoft Sql Server it starts at the bottom left corner.

阅读更多关于理解SVG的viewport,viewBox【1】

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> viewport表示的是svg可视区大小，具体体现就是svg元素的width和height属性值所圈起来的区域： <svg width="400" height="300" style="border:1px solid #cd0000;"> <rect x="10" y="5" width="20" height="15" fill="#cd0000"/> </svg> 上述svg代码便定义了一个400px*300px的viewpoint，默认单位是px，也可以是其他web单位。上述代码的效果是：在一个400px*300px的舞台上的(10,5)坐标位置放了一个20px*15px的矩形。显示效果全在意料之中，但是，如果svg增加新的属性viewBox，情况就大不相同了，代码： <svg width="400" height="300" viewBox="0,0,40,30" style="border:1px solid #cd0000;"> <rect x="10" y="5" width="20" height="15" fill="#cd0000"/> </svg> 效果：只是在svg标签中增加了 viewBox="0,0,40,30" 就发生如此大的变化，那viewBox的4个属性值分别是什么

阅读更多关于 Maintaining fixed-thickness lines in WPF with Viewbox scaling/stretching

问题 I have a <Grid> which contains some vertical and horizontal <Line> s. I want the grid to be scalable with the window size, and retain its aspect ratio, so it's contained in a <Viewbox Stretch="Uniform"> . However, I also want the lines to always render with a width of 1 pixel, so I use: Line line = new Line(); line.SetValue(RenderOptions.EdgeModeProperty, EdgeMode.Aliased); // other line settings here... This makes the lines' initial appearance ideal, but as soon as you start resizing the
