PowerPoint 处理

创建演示文稿 (Python)

from pptx import Presentation
from pptx.util import Inches, Pt

prs = Presentation()

# 添加标题幻灯片
title_slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(title_slide_layout)
title = slide.shapes.title
subtitle = slide.placeholders[1]
title.text = "Hello, World!"
subtitle.text = "python-pptx 演示"

# 添加内容幻灯片
bullet_slide_layout = prs.slide_layouts[1]
slide = prs.slides.add_slide(bullet_slide_layout)
shapes = slide.shapes
title_shape = shapes.title
body_shape = shapes.placeholders[1]
title_shape.text = "关键点"
tf = body_shape.text_frame
tf.text = "第一个要点"
p = tf.add_paragraph()
p.text = "第二个要点"
p.level = 1

prs.save('presentation.pptx')

添加图片

from pptx.util import Inches

blank_layout = prs.slide_layouts[6]
slide = prs.slides.add_slide(blank_layout)

left = Inches(1)
top = Inches(1)
width = Inches(5)
slide.shapes.add_picture('image.png', left, top, width=width)

添加表格

rows, cols = 3, 4
left = Inches(1)
top = Inches(2)
width = Inches(6)
height = Inches(1.5)

table = slide.shapes.add_table(rows, cols, left, top, width, height).table

# 设置列宽
table.columns[0].width = Inches(2)

# 添加内容
table.cell(0, 0).text = "标题 1"
table.cell(1, 0).text = "数据 1"

添加图表

from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE

chart_data = CategoryChartData()
chart_data.categories = ['东部', '西部', '中西部']
chart_data.add_series('销售额', (19.2, 21.4, 16.7))

x, y, cx, cy = Inches(2), Inches(2), Inches(6), Inches(4.5)
slide.shapes.add_chart(
    XL_CHART_TYPE.COLUMN_CLUSTERED, x, y, cx, cy, chart_data
)

编辑现有演示文稿

prs = Presentation('existing.pptx')

# 访问幻灯片
for slide in prs.slides:
    for shape in slide.shapes:
        if shape.has_text_frame:
            print(shape.text_frame.text)

# 修改文本
slide = prs.slides[0]
slide.shapes.title.text = "新标题"

prs.save('modified.pptx')

最佳实践

• 使用幻灯片布局保持一致性
• 保持文本简洁，使用视觉元素
• 使用Inches()或Pt()进行尺寸设置
• 创建过程中频繁保存
