PDF 工具s

工具s for viewing, 提取ing, and editing PDF files using Python libraries (pdfplumber and PyPDF2).

Quick 启动

All scripts require dependencies:

pip3 安装 pdfplumber PyPDF2

Core Operations 提取 Text

提取 text from PDF (all pages or specific pages):

scripts/提取_text.py document.pdf scripts/提取_text.py document.pdf -p 1 3 5 scripts/提取_text.py document.pdf -o 输出.txt

获取 PDF 信息

View metadata and structure:

scripts/pdf_信息.py document.pdf scripts/pdf_信息.py document.pdf -f json

Merge PDFs

Combine multiple PDFs into one:

scripts/merge_pdfs.py file1.pdf file2.pdf file3.pdf -o merged.pdf

Split PDF

Split into individual pages:

scripts/split_pdf.py document.pdf -o 输出_dir/

Split by page ranges:

scripts/split_pdf.py document.pdf -o 输出_dir/ -m ranges -r "1-3,5-7,10-12"

Rotate Pages

Rotate all pages or specific pages:

scripts/rotate_pdf.py document.pdf -o rotated.pdf -r 90 scripts/rotate_pdf.py document.pdf -o rotated.pdf -r 180 -p 1 3 5

Edit Text

添加 text overlay on a page:

scripts/edit_text.py document.pdf -o edited.pdf --overlay "New Text" --page 1 --x 100 --y 700 scripts/edit_text.py document.pdf -o edited.pdf --overlay "Watermark" --page 1 --x 200 --y 400 --font-size 20

Replace text (limited, works best for simple cases):

scripts/edit_text.py document.pdf -o edited.pdf --replace "Old Text" "New Text"

Note: PDF text editing is complex due to the 格式化. The overlay method is more reliable than replacement.

工作流 Patterns Viewing PDF Content 获取 basic 信息: scripts/pdf_信息.py file.pdf 提取 text to preview: scripts/提取_text.py file.pdf -p 1 提取 full text if needed: scripts/提取_text.py file.pdf -o content.txt Reorganizing PDFs Split into pages: scripts/split_pdf.py 输入.pdf -o pages/ Merge selected pages: scripts/merge_pdfs.py pages/page_1.pdf pages/page_3.pdf -o reordered.pdf 提取ing Sections 获取 page count: scripts/pdf_信息.py document.pdf Split by ranges: scripts/split_pdf.py document.pdf -o sections/ -m ranges -r "1-5,10-15" Advanced Usage

Notes Page numbers are 1-索引ed in all scripts (page 1 = first page) Text 提取ion works best with text-based PDFs (not 扫描ned images) Rotation angles: 90, 180, 270, or -90 (counterclockwise) All scripts 验证 file existence before processing
