文本框样式的调整
import os
os.chdir("D:\\python_major\\auto_office18")
from pptx import Presentation
from pptx.enum.text import MSO_ANCHOR,MSO_AUTO_SIZE
from pptx.util import Cm
from pptx.dml.color import RGBColor
prs = Presentation()
bullet_slide_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(bullet_slide_layout)
left = top = Cm(3)
height = Cm(2)
width = Cm(10)
text_box =slide.shapes.add_textbox(left,top,width,height)
tf = text_box.text_frame
tf.text = '这是一段文本框的文字'
tf.margin_bottom = Cm(0.1) #下边距
tf.margin_left = 0 #左边距
tf.vertical_anchor = MSO_ANCHOR.BOTTOM #对齐文本方式：底端对齐
tf.word_wrap = True #框中文字自动换行
prs.save('test.pptx')
–> 输出结果为：
文本框背景颜色调整
from pptx.dml.color import RGBColor
text_box =slide.shapes.add_textbox(left,top,width,height)
fill = text_box.fill
fill.solid()
fill.fore_color.rgb = RGBColor(247,150,70)
–> 输出结果为：
文本框边框样式调整
line = text_box.line
line.color.rgb = RGBColor(255,0,0)
line.width = Cm(0.3)
–> 输出结果为：
段落对齐调整
p.Alignment = 对齐方式
from pptx.enum.text import PP_ALIGN
p = tf.add_paragraph()
p.text = '这是第二段文字'
p.alignment = PP_ALIGN.RIGHT
–> 输出结果为：
段落其他样式调整
与word中的使用非常相似
| .add_run() | 添加新的文字块 |
|---|---|
| .level | 段落缩进层级 |
| .line_spacing | 段落行间距 |
| .runs | 段落内的文字块 |
| .space_after | 段后距 |
| .space_before | 段前距 |
字体样式调整
| .font.name | 字体名称（可以直接设定为中文字体） |
|---|---|
| .font.bold | 是否加粗 |
| .font.italic | 是否斜体 |
| .font.color | 字体颜色 |
| .font.size | 字体大小 |
from pptx.util import Pt
from pptx.dml.color import RGBColor
p = tf.add_paragraph()
p.text = '这是第二段文字'
p.alignment = PP_ALIGN.RIGHT
p.font.name = '微软雅黑'
p.font.bold = True
p.font.color.rgb = RGBColor(0,150,70)
p.font.size = Pt(30)
–> 输出结果为：
综合应用
编写一个Python程序，要求
（1） 打开文件第四节课作业模板.pptx
（2） 参考第四节课作业最终成果参考.pptx的最中效果
（3） 用编程的方式从模板文件来复现最终效果
作业模板.pptx 的模板样式如下
最终成果参考.pptx 的样式为：
参考代码
步骤一、前期准备
import os
os.chdir("D:\\python_major\\auto_office18")
from pptx import Presentation
from pptx.enum.text import MSO_ANCHOR,MSO_AUTO_SIZE
from pptx.util import Cm，Pt
from pptx.dml.color import RGBColor
import datetime
该部分代码完成的功能是：设置程序运行路径、导入相关的库
步骤二、查找模板信息和占位符
需要先把“第四节课作业模板.pptx”打开后，进入到视图窗口下点击“幻灯片母版”，然后在左侧slide中找到幻灯片1所使用的样式，具体操作如下
首先，打开文件进入出事界面，然后点击菜单栏里的“视图”
其次，选择幻灯片母版
接着，进入母版中找到幻灯片1所使用的样式slide（表格布局样式）
这时候鼠标放在侧的红色框内，会自动弹出一个提示框 --> 表格布局 版式：由幻灯片 1 使用。这时候就找到了模板中幻灯片所对应的的板式，需要记住其编号（也就是序号16）
最后，通过代码获得相应的占位符spaceholders
prs = Presentation("第四节课作业模板.pptx")
slide = prs.slides.add_slide(prs.slide_layouts[16])
for shape in slide.placeholders:
phf = shape.placeholder_format
print(f'{phf.idx}--{shape.name}--{phf.type}')
–> 输出结果为：
检验，在for循环的最后一步加上如下代码然后再保存
shape.text = f'{phf.idx}--{phf.type}'
–> 输出结果为：
至此，模板信息和占位符的查找就已经完毕，接下来就是想pptx里面写入内容了
步骤三、向pptx中写入内容
首先、插入title和body
body = slide.placeholders[1]
title = slide.placeholders[0]
title.text = "财务信息"
body.text = "LOREM IPSUM DOLOR SIT AMET, CONSECTETUER ADIPISCING ELIT.MAECENAS PORTTITOR"
其次、插入图片
通过图片占位符插入图片，这里使用的方法不是add_picture而是insert_picture的方法，这里需要注意把模板中的图片另存到程序的运行路径下，保存的类型为png格式
pic = slide.placeholders[13]
pic.insert_picture("图片1.png")
然后、插入最下端的标识页数和日期
top = Cm(15.6)
left = Cm(28)
height = width = Cm(3)
today = datetime.datetime.today()
bottom_date = "{} 年 {} 月 {} 日".format(today.year,today.month,today.day)
text_box = slide.shapes.add_textbox(left,top,height,width)
tf = text_box.text_frame
p = tf.add_paragraph()
p.text = bottom_date
p.font.name = '微软雅黑'
p.font.size= Pt(12)
p.font.color.rgb = RGBColor(255,255,255)
top = Cm(15.6)
left = Cm(2.25)
height = width = Cm(2)
text_box = slide.shapes.add_textbox(left,top,height,width)
tf = text_box.text_frame
p = tf.add_paragraph()
p.text = "1"
p.font.name = '微软雅黑'
p.font.size= Pt(12)
p.font.color.rgb = RGBColor(255,255,255)
最后、处理表格占位符
这里和处理图片占位符的方式类似，使用的insert_table方法，查看了官方示例以及百度了很多文档及别人分享的代码，只看到过如何通过表格占位符插入表格已经向表格中写入元素，以及对表格的合并和拆解，但是没有找到相关对于表格属性（填充）以及文字属性（大小、字体、对齐方式等），这里就只能按照默认生成的样式进行输出
table = slide.placeholders[14]
table.top = Cm(1)
table.left = Cm(12)
data =[
["","2017","2018","2019",""],
["用户","50,000","400,000","1,600,000",""],
["作业","500,000","4,000,000","16,000,000",""],
["每个作业的平均价格","75","80","90",""],
["公司收入 @ 15%","5,625,000","48,000,000","216,000,000",""],

["- 客户服务","1,687,500","9,600,000","21,600,000","10%"],
["- 产品开发","562,500","2,400,000","10,800,000","5%"],
["- 杂项费","281,250","2,400,000","4,320,000","2%"],
["总运营成本","7,596,750","52,800,000","187,920,000",""],
["EBIT","-1,968,750","-4,800,000","28,080,000","13%"]
]
rows,cols = 14,5
table = table.insert_table(rows,cols).table
table.columns[0].width = Cm(6.5)
table.columns[1].width = Cm(4)
table.columns[2].width = Cm(4)
table.columns[3].width = Cm(4)
table.columns[4].width = Cm(2)
for row in range(rows):
for col in range(cols):
table.cell(row,col).text = str(data[row][col])
