用TikzEdt重制一个图片

hbghlyj

tikzedt.org/

打开TikzEdt, 保存为tex, 这里是D:\New Tikzfile.tex 把图片保存在同一目录下,这里是D:\d.png 把Grid (网格尺寸)设为0.1 插入图片: \begin{tikzpicture} \node[inner sep=0pt] at (0,0){\includegraphics{./d.png}}; \end{tikzpicture} 复制代码
用Node工具, 点击图片的半圆的直径两端 编辑器出现 \node at (-2.6,-2.8) {}; \node at (2.6,-2.8) {}; 复制代码 将节点命名为a和b \node (a) at (-2.6,-2.8) {}; \node (b) at (2.6,-2.8) {}; 复制代码 在编辑器写入\fill半圆的代码 \fill[color=gray!80] (b) arc(0:180:2.6) (a); 复制代码
用Ellipse工具, 按Ctrl画圆, 点击图片中的圆的中心和圆上的一点. 编辑器出现 \draw  (0,1.1) circle (1.7); 复制代码 用Select and move工具, 拖动新创建的节点, 调整圆心的位置. 在编辑器把自动生成的\draw改为\fill \fill[color=gray!80]  (0,1.1) circle (1.7); 复制代码
把插入的图片删除,得到最终代码 \begin{tikzpicture} \node (a) at (-2.6,-2.8) {}; \node (b) at (2.6,-2.8) {}; \fill[color=gray!80] (b) arc(0:180:2.6) (a); \fill[color=gray!80]  (0,1.1) circle (1.7); \end{tikzpicture} 复制代码 完毕

•        Grid: The grid spacing can be set in the appropriate toolbar. Alternatively, ALT temporarily sets the grid spacing to 0, while ALT+SHIFT cuts it in half.
•        Snippets: Snippets can be inserted as styles, as full code samples, or as-is. You can create your own snippets under Settings->SnippetManager
•        Snippet thumbnails are created from the snippet's Latex code. You can (re-)create snippet thumbnails in the SnippetManager.
•        Styles: You can set styles to be used with the WYSIWYG tools in the tools toolbar.
•        TikzEdt supports both standalone document (containing \documentclass{} etc.) and tikz pictures to be \input{}-ted into a master document. However for correct bounding box determination you should use \PreviewEnvironment{tikzpicture} in your standalone documents.
•        Press Ctrl to open recent files in the File menu in a new window.
•        You can run TikzEdt in portable mode by supplying the -p or --portable command line switch. In this case TikzEdt stores its settings in the application folder, which must be writable.

那个Edge tool为什么是向上的光标呢? 点击时很不方便.

为什么--cycle没效果? 比如 \draw (v1)--(v2)--cycle; 只画出(v1)到(v2), 没有闭合路径.

用

1. \makeatletter
2. \f@size

可以发现http://i.upmath.me默认的字号为10.95
所以从TikzEdt粘贴到这里,需要加上

1. \fontsize{10}{12}\selectfont
