PDF All-in-One

PDF All-in-One Processing 图形界面de Overview

This 图形界面de covers comprehensive PDF processing operations including conversion to images. For advanced features, see REFERENCE.md.

Workspace Directory: /pdf-all-in-one-workspace/

Quick 启动 from pypdf 导入 PdfReader, PdfWriter

# Read a PDF reader = PdfReader("document.pdf") print(f"Pages: {len(reader.pages)}")

# 提取 text text = "" for page in reader.pages: text += page.提取_text()

PDF to Image Conversion Convert PDF Pages to PNG/JPG from pdf2image 导入 convert_from_path 导入 os

# Configuration pdf_path = "输入.pdf" 输出_dir = "pdf-all-in-one-workspace/输出_images" os.makedirs(输出_dir, exist_ok=True)

# Convert PDF to images images = convert_from_path(pdf_path, dpi=150)

# Save each page as PNG for i, image in enumerate(images): 输出_path = f"{输出_dir}/page_{i+1}.png" image.save(输出_path, "PNG") print(f"Saved: {输出_path}")

print(f"Total pages converted: {len(images)}")

Convert with Specific Page Range from pdf2image 导入 convert_from_path

# Convert only pages 1-5 images = convert_from_path("document.pdf", dpi=200, first_page=1, last_page=5)

for i, image in enumerate(images): image.save(f"pdf-all-in-one-workspace/page_{i+1}.jpg", "JPEG", 质量=95)

Prerequisites # 安装 Python 库 pip 安装 pdf2image

# 安装 系统 dependency (poppler) # Ubuntu/Debian: sudo apt-获取 安装 poppler-utils

# CentOS/RHEL: sudo yum 安装 poppler-utils

# macOS: brew 安装 poppler

Python Libraries pypdf - Basic Operations Merge PDFs from pypdf 导入 PdfWriter, PdfReader

writer = PdfWriter() for pdf_file in ["doc1.pdf", "doc2.pdf", "doc3.pdf"]: reader = PdfReader(pdf_file) for page in reader.pages: writer.添加_page(page)

with open("merged.pdf", "wb") as 输出: writer.write(输出)

Split PDF reader = PdfReader("输入.pdf") for i, page in enumerate(reader.pages): writer = PdfWriter() writer.添加_page(page) with open(f"pdf-all-in-one-workspace/page_{i+1}.pdf", "wb") as 输出: writer.write(输出)

提取 Metadata reader = PdfReader("document.pdf") meta = reader.metadata print(f"Title: {meta.title}") print(f"Author: {meta.author}") print(f"Subject: {meta.subject}") print(f"创建器: {meta.创建器}")

Rotate Pages reader = PdfReader("输入.pdf") writer = PdfWriter()

page = reader.pages[0] page.rotate(90) # Rotate 90 degrees clockwise writer.添加_page(page)

with open("rotated.pdf", "wb") as 输出: writer.write(输出)

pdfplumber - Text and Table 提取ion 提取 Text with Layout 导入 pdfplumber

with pdfplumber.open("document.pdf") as pdf: for page in pdf.pages: text = page.提取_text() print(text)

提取 Tables with pdfplumber.open("document.pdf") as pdf: for i, page in enumerate(pdf.pages): tables = page.提取_tables() for j, table in enumerate(tables): print(f"Table {j+1} on page {i+1}:") for row in table: print(row)

Advanced Table 提取ion 导入 pandas as pd

with pdfplumber.open("document.pdf") as pdf: all_tables = [] for page in pdf.pages: tables = page.提取_tables() for table in tables: if table: df = pd.DataFrame(table[1:], columns=table[0]) all_tables.应用end(df)

if all_tables: combined_df = pd.concat(all_tables, ignore_索引=True) combined_df.to_excel("pdf-all-in-one-workspace/提取ed_tables.xlsx", 索引=False)

报告lab - 创建 PDFs Basic PDF Creation from 报告lab.lib.pagesizes 导入 letter from 报告lab.pdfgen 导入 canvas

c = canvas.Canvas("pdf-all-in-one-workspace/hello.pdf", pagesize=letter) width, height = letter

c.drawString(100, height - 100, "Hello World!") c.drawString(100, height - 120, "This is a PDF 创建d with 报告lab") c.line(100, height - 140, 400, height - 140) c.save()

Subscripts and Superscripts from 报告lab.platypus 导入 Paragraph from 报告lab.lib.styles 导入 获取SampleStyleSheet

styles = 获取SampleStyleSheet() chemical = Paragraph("H2O", styles['Normal']) squared = Paragraph("x2 + y2", styles['Normal'])

Command-Line 工具s pdftotext (poppler-utils) # 提取 text pdftotext 输入.pdf 输出.txt
