-## Xmind Parsing Method
-
-> v0.2.7+
-
-You can get the `Xmind` parsing method as follows:
-
-```js
-import MindMap from "simple-mind-map";
-
-console.log(MindMap.xmind);
-```
-
-The `MindMap.xmind` object has two methods attached:
-
-### parseXmindFile(file)
-
-Parsing the `.xmind` file and returning the parsed data. Note that this is
-complete data, including the node tree, theme, and structure. You can use
-`mindMap.setFullData(data)` to render the returned data to the canvas.
-
-`file`: `File` object
-
-### transformXmind(content)
-
-Convert `xmind` data. The `.xmind` file is essentially a `zip` file that can be
-decompressed by changing the suffix to zip. Inside, there is a `content.json`
-file. If you have parsed this file yourself, you can pass the contents of this
-file to this method for conversion. The converted data is the complete data,
-including the node tree, theme, structure, etc. You can use
-`mindMap.setFullData(data)` to render the returned data to the canvas.
-
-`content`: the contents of the `content.json` file within the `.xmind` zip
-package
-
-### transformOldXmind(content)
-
-> v0.2.8+
-
-For data parsing of the `xmind8` version, because the `.xmind` file in this
-version does not have a `content.json`, it corresponds to `content.xml`.
-
-`content`: the contents of the `content.xml` file within the `.xmind` zip

 For all configurations of theme, please refer to [Default Topic](https://github.com/wanglin2/mind-map/blob/main/simple-mind-map/src/themes/default.js). The `defineTheme`method will merge the configuration you passed in with the default configuration. Most of the themes  do not need custom many parts.

+### render(callback)

+- `callback`: `v0.3.2+`, `Function`, Called when the re-rendering is complete

 Triggers a full rendering, which will reuse nodes for better performance. If
 only the node positions have changed, this method can be called to `reRender`.

-### reRender()
+### reRender(callback)
+
+- `callback`: `v0.3.2+`, `Function`, Called when the re-rendering is complete

 Performs a full re-render, clearing the canvas and creating new nodes. This has
 poor performance and should be used sparingly.

-<h2>Xmind Parsing Method</h2>
-<blockquote>
-<p>v0.2.7+</p>
-</blockquote>
-<p>You can get the <code>Xmind</code> parsing method as follows:</p>
-<pre class="hljs"><code><span class="hljs-keyword">import</span> MindMap <span class="hljs-keyword">from</span> <span class="hljs-string">&quot;simple-mind-map&quot;</span>;
-
-<span class="hljs-built_in">console</span>.log(MindMap.xmind);
-</code></pre>
-<p>The <code>MindMap.xmind</code> object has two methods attached:</p>
-<h3>parseXmindFile(file)</h3>
-<p>Parsing the <code>.xmind</code> file and returning the parsed data. Note that this is
-complete data, including the node tree, theme, and structure. You can use
-<code>mindMap.setFullData(data)</code> to render the returned data to the canvas.</p>
-<p><code>file</code>: <code>File</code> object</p>
-<h3>transformXmind(content)</h3>
-<p>Convert <code>xmind</code> data. The <code>.xmind</code> file is essentially a <code>zip</code> file that can be
-decompressed by changing the suffix to zip. Inside, there is a <code>content.json</code>
-file. If you have parsed this file yourself, you can pass the contents of this
-file to this method for conversion. The converted data is the complete data,
-including the node tree, theme, structure, etc. You can use
-<code>mindMap.setFullData(data)</code> to render the returned data to the canvas.</p>
-<p><code>content</code>: the contents of the <code>content.json</code> file within the <code>.xmind</code> zip
-package</p>
-<h3>transformOldXmind(content)</h3>

-<p>v0.2.8+</p>

+# RichText plugin
+
+> v0.4.0+
+
+> Note: This is a testing nature and imperfect function
+
+This plugin provides the ability to edit rich text of nodes, and takes effect after registration.
+
+By default, node editing can only uniformly apply styles to all text in the node. This plugin can support rich text editing effects. Currently, it supports bold, italic, underline, strikethrough, font, font size, color, and backgroundColor. Underline and line height are not supported.
+
+The principle of this plugin is to use [Quill](https://github.com/quilljs/quill) editor implements rich text editing, and then uses the edited `DOM` node directly as the text data of the node, and embeds the `DOM` node through the `svg` `foreignObject` tag during rendering.
+
+This also caused a problem, that is, the function of exporting as a picture was affected, The original principle of exporting `svg` as an image is very simple, Get the `svg` string, and then create the `blob` data of the `type=image/svg+xml` type. Then use the `URL.createObjectURL` method to generate the `data:url` data. Then create a `Image` tag, use the `data:url` as the `src` of the image, and finally draw the image on the `canvas` object for export, However, after testing, when the `DOM` node is embedded in the `svg`, this method of export will cause errors, and after trying many ways, the perfect export effect cannot be achieved, The current method is to traverse the `foreignObject` node in `svg`, using [html2canvas](https://github.com/niklasvh/html2canvas) Convert the `DOM` node in the `foreignObject` node into an image and then replace the `foreignObject` node. This method can work, but it is very time-consuming. Because the `html2canvas` conversion takes a long time, it takes about 2 seconds to convert a node. This leads to the more nodes, the slower the conversion time. Therefore, it is recommended not to use this plugin if you cannot tolerate the long time of export.
+
+If you have a better way, please leave a message.
+
+## Register
+
+```js
+import MindMap from 'simple-mind-map'
+import RichText from 'simple-mind-map/src/RichText.js'
+
+MindMap.usePlugin(RichText, opt?)
+```
+
+After registration and instantiation of `MindMap`, the instance can be obtained through `mindMap.richText`.
+
+### Register options
+
+The `opt` option can pass the following parameters:
+
+- `opt.fontFamilyList`
+
+Replace the built-in font list during rich text editing. The built-in list is:
+
+```js
+[
+  '宋体, SimSun, Songti SC',
+  '微软雅黑, Microsoft YaHei',
+  '楷体, 楷体_GB2312, SimKai, STKaiti',
+  '黑体, SimHei, Heiti SC',
+  '隶书, SimLi',
+  'andale mono',
+  'arial, helvetica, sans-serif',
+  'arial black, avant garde',
+  'comic sans ms',
+  'impact, chicago',
+  'times new roman',
+  'sans-serif',
+  'serif'
+]
+```
+
+- `opt.fontSizeList`
+
+Replace the built-in font size list during rich text editing. The built-in list is:
+
+```js
+[1, 2, 3, ...100]
+```
+
+## Method
+
+### selectAll()
+
+Select All. When the node is being edited, you can select all the text in the node through this method.
+
+### formatText(config = {})
+
+- `config`：Object. The key is the style attribute and the value is the style value. The complete configuration is as follows:
+
+```js
+{
+    font: '字体',
+    size: '12px,' // font size
+    bold: true, // Bold or not, true/false 
+    italic: true, // Italic or not, true/false 
+    underline: true, // Show underline or not, true/false 
+    strike: true, // Whether to display strikethrough, true/false 
+    color: '#333' // color
+}
+```
+
+Formats the currently selected text.
+
+### formatRangeText(range, config = {})
+
+- `range`：The range object of `Quill`, has the following format:
+
+```js
+{
+    index,
+    length
+}
+```
+
+- `config`：Same as `formatText` method
+
+Formats the text of the specified range.
+
+### formatAllText(config = {})
+
+- `config`：Same as `formatText` method
+
+Formats all text of the current edit node.
+
+### removeFormat()
+
+> v0.4.1+
+
+Clears the style of the currently selected text.
+
+### normalStyleToRichTextStyle(style) 
+
+Converts a normal node style object to a rich text style object. Because there are differences between node style attributes and rich text style attributes during non-rich text editing, a conversion operation is required. For example:
+
+```js
+{
+    fontFamily: 'xxx'
+}
+
+// After conversion
+
+{
+    font: 'xxx'
+}
+```
+
+### richTextStyleToNormalStyle(config)
+
+Converts rich text style objects to normal node style objects. For example:
+
+```js
+{
+    size: '16px'
+}
+
+// After conversion
+
+{
+    fontSize: 16
+}
+```
+
+### handleSvgDomElements(svg)
+
+- `svg`: `svg` node
+
+Convert the `dom` element embedded in the `svg` into a picture and return a `Promise`.
+
+### transformAllNodesToNormalNode()
+
+Convert all nodes to non-rich text nodes.
