对于实现Word文档与PDF文档的格式转化,可以使用Python中的docx和pdfminer库。docx库可以读写Word文档,pdfminer库可以提取PDF文本内容。
具体步骤如下:
1. 安装docx和pdfminer库:
```
pip install python-docx
pip install pdfminer
```
2. 实现Word文档转为PDF文档:
```python
from docx2pdf import convert
# 将Word文档转为PDF文档
convert('input.docx', 'output.pdf')
```
3. 实现PDF文档转为Word文档:
```python
import pdfminer.high_level
from docx import Document
from docx.shared import Inches
# 读取PDF文本内容
text = pdfminer.high_level.extract_text('input.pdf')
# 创建Word文档
document = Document()
# 将PDF文本内容添加到Word文档中
document.add_paragraph(text)
# 保存Word文档
document.save('output.docx')
```
4. 实现PDF文件的合并:
```python
from PyPDF2 import PdfFileMerger
# 合并两个PDF文件
pdfs = ['file1.pdf', 'file2.pdf']
merger = PdfFileMerger()
for pdf in pdfs:
merger.append(pdf)
merger.write("merged.pdf")
merger.close()
```
5. 实现PDF文件的拆分:
```python
from PyPDF2 import PdfFileReader, PdfFileWriter
# 拆分单个PDF文件
pdf = 'input.pdf'
pdf_reader = PdfFileReader(pdf)
for page_num in range(pdf_reader.getNumPages()):
pdf_writer = PdfFileWriter()
pdf_writer.addPage(pdf_reader.getPage(page_num))
output_filename = f'page_{page_num}.pdf'
with open(output_filename, 'wb') as out:
pdf_writer.write(out)
```
6. 实现PDF页面旋转:
```python
from PyPDF2 import PdfFileReader, PdfFileWriter
# 对单个PDF页面进行旋转
pdf = 'input.pdf'
pdf_reader = PdfFileReader(pdf)
# 旋转第一页90度
page = pdf_reader.getPage(0)
page.rotateClockwise(90)
pdf_writer = PdfFileWriter()
pdf_writer.addPage(page)
with open('output.pdf', 'wb') as out:
pdf_writer.write(out)
```
7. 实现PDF页面增加水印:
```python
from PyPDF2 import PdfFileReader, PdfFileWriter
from reportlab.lib.units import mm
from reportlab.pdfgen import canvas
# 对单个PDF页面添加水印
pdf = 'input.pdf'
pdf_reader = PdfFileReader(pdf)
# 添加水印
watermark = 'Confidential'
c = canvas.Canvas('watermark.pdf')
c.setFont('Helvetica-Bold', 36)
c.rotate(45)
c.drawString(0, 0, watermark)
c.save()
# 将水印添加到PDF页面中
page = pdf_reader.getPage(0)
watermark_reader = PdfFileReader('watermark.pdf')
watermark_page = watermark_reader.getPage(0)
page.mergePage(watermark_page)
pdf_writer = PdfFileWriter()
pdf_writer.addPage(page)
with open('output.pdf', 'wb') as out:
pdf_writer.write(out)
```
