1 说明：

=====

1.1 Pixelhouse：一个极简主义的绘图库，用于在python中制作精美的动画。

1.2 可以移动任何可以绘制的东西。配有漂亮的渐变，类似instagram的滤镜和弹性变换。

1.3 官网英文：

A minimalist drawing library for making beautiful animations in python.

Anything that can be drawn can be moved.

Comes with beautiful gradients, instagram-like filters, and elastic transforms.

2 准备：

=====

2.1 环境：

华为笔记本电脑、深度deepin-linux操作系统、python3.8和微软vscode编辑器。

2.2 传送门：

2.3 安装：

pip install pixelhouse#本机安装#sudo pip3.8 install pixelhouse#推荐安装#sudo pip3.8 install -i  pixelhouse

===以下代码为注释讲解版===

3 Hello world：

==========

3.1 代码：

import pixelhouse as ph#C = ph.Canvas() #采用默认#默认#Canvas(width=200, height=200, extent=4.0, bg='black', img=None, name='pixelhouseImage', shift=8)#指定参数值C = ph.Canvas(800, 800,bg='pink', name='win one')  #中文乱码#在C中加入文本文字#C+=ph.text('Hello World')  #默认设置，不可以显示中文#自定义：字体（需自行下载中文字体：hwfs=华文仿宋，放在根目录下），字体大小设置C+=ph.text('Hello World；你好世界',color='green',font='hwfs.ttf',font_size=0.5)  #保存#C.save("/home/xgj/Desktop/Pixelhouse/Helloworld.png")#显示C.show()

4 palette（调色板）：

===============

4.1 注释版调色板和颜色列表代码：

#pixelhouse=像素屋import pixelhouse as phpal=ph.palette(5)#print(pal[:])#[[232, 221, 203, 255], [205, 179, 128, 255], [3, 101, 100, 255], [3, 54, 73, 255], [3, 22, 52, 255]]#pal[2],得到：[3, 101, 100, 255] #草绿色'''C=ph.Canvas(1000,1000,extent=8.0,bg=pal[3],)C.show()

4.2 注意：复习和总结

#当≥5时，列表仍是5组，但是列表内的颜色值发生改变

#打印每个像素点的颜色RGBA的值(r,g,b,alpha)

#我们常见的RGB图像通常只有R、G、B三个通道

#A通道=alpha通道，是指给图像添加透明度

rgba表示颜色方式为rgba（a,b,c,d）

其中abc用来表示颜色，d用来表示透明度

(r, g, b, a)有4个值，每个都是0到255，RGBA的a（d值）就代表透明度。

5 palette_blocks=调色板块：

====================

5.1 代码：

#palette_blocks=调色板块'''#方法一import pixelhouse as ph#默认ph.palette_blocks(range(20)).show()''''''#方法二，与上面效果相同import pixelhouse as phph_win=ph.palette_blocks(range(20))ph_win.show()'''import pixelhouse as ph#自定义columns为4ph_win=ph.palette_blocks(range(20),columns=4)#默认#palette_numbers, columns=2, show_number=True, width=400ph_win.show()
