# getColorbarFromImage

## 用法

截图，然后运行本代码，颜色自动复制到剪贴板，一个列表形式

截图时候尽量别截其它无关部分，不然容易误判的

## 示例

## 用途

如matplotlib、cartopy等

```python

fig, ax = plt.subplots(figsize=(12, 0.36), dpi=150)

cmap = mpl.colors.ListedColormap(hex_colors[1:-1])

cmap.set_under(hex_colors[0])

cmap.set_over(hex_colors[-1])

plt.colorbar(mpl.cm.ScalarMappable(cmap=cmap, norm=mpl.colors.Normalize(0, 10)), 

             orientation='horizontal', extend='both', cax=ax)

```

## 需要的库库

```python

from PIL import ImageGrab

import numpy as np

from PIL import Image

import matplotlib.pyplot as plt 

import matplotlib as mpl

import pyperclip

```
