+# AssociativeLine plugin
+
+> v0.4.5+
+
+> The function of adjusting associated line control points is supported from v0.4.6+
+
+This plugin is used to support the addition of associative lines.
+
+The plugin is currently not fully functional, and does not support adding text to association lines.
+
+## Register
+
+```js
+import MindMap from 'simple-mind-map'
+import AssociativeLine from 'simple-mind-map/src/AssociativeLine.js'
+
+MindMap.usePlugin(AssociativeLine)
+```
+
+After registration and instantiation of `MindMap`, the instance can be obtained through `mindMap.associativeLine`.
+
+## Config
+
+Support for modifying the thickness and color of associated lines, divided into default and active states. The configuration is as follows:
+
+- `associativeLineWidth`: The thickness of the default state of the associated line. The default value is `2`
+
+- `associativeLineColor`: Color of the default state of associative lines. The default value is `rgb(51, 51, 51)`
+
+- `associativeLineActiveWidth`: The thickness of the active state of the associated line. The default value is `8`
+
+- `associativeLineActiveColor`: The color of the active state of the associated line. The default value is `rgba(2, 167, 240, 1)`
+
+The configuration is provided as a theme, so if you want to modify these four properties, you can modify them using the `mindMap.setThemeConfig(config)` method.
+
+## Props
+
+### mindMap.associativeLine.lineList
+
+Currently, all connection line data, array types, and each item of the array are also an array:
+
+```js
+[
+    path, // Connector node
+    clickPath, // Invisible click line node
+    node, // Start node
+    toNode // Target node
+]
+```
+
+### mindMap.associativeLine.activeLine
+
+The currently active connection line and array type are the same as the structure of each item in the `lineList` array.
+
+## Methods
+
+### renderAllLines()
+
+Re-render all associated lines.
+
+### removeAllLines()
+
+Remove all associated lines.
+
+### createLineFromActiveNode()
+
+Create an associated line from the current active node. If there are multiple active nodes, the default is the first node.
+
+After calling this method, an association line will be rendered from the first active node to the current mouse real-time position. When a target node is clicked, it represents completion of creation. An association line will be rendered between the first active node and the clicked node.
+
+### createLine(fromNode)
+
+Creates an associative line starting at the specified node.
+
+After calling this method, an association line will be rendered from the specified node to the current mouse real-time position. When a target node is clicked, it represents completion of creation, and an association line will be rendered between the specified node and the clicked node.
+
+### addLine(fromNode, toNode)
+
+Add an associative line directly.
+
+Calling this method will directly create an association line from the `fromNode` to the `toNode` node.
+
+### removeLine()
+
+Deletes the currently active associative line. Clicking on an associated line is considered active.
+
+### clearActiveLine()
+
+Clears the active state of the currently active association line.

+# 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.
+
+### focus()
+
+> v0.4.7+
+
+Focus.
+
+### 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.
