Overview

Convert a PDF into JPEG page images using pdftoppm from poppler-utils, then optionally zip the generated JPGs.

Requirements

- pdftoppm must be available in INLINECODE3
Install the poppler-utils package before running the scripts

Install `poppler-utils`

- Debian / Ubuntu:

CODEBLOCK0

- Windows:

- Install Poppler via a package manager, then make pdftoppm.exe available in your PATH - Common options: - winget install -e --id oschwartz10612.Poppler - choco install poppler - INLINECODE10

- macOS:

CODEBLOCK1

Standard workflow

1. Convert the PDF with INLINECODE11
Bundle the output images with scripts/zip_jpgs.sh if needed

CODEBLOCK2

Scripts

`scripts/pdf2jpg.sh`

- Prompts for the PDF path if none is supplied
Verifies the input file exists
Verifies pdftoppm is installed and prints a poppler-utils install hint if not
Writes JPEGs beside the PDF using the PDF basename as the output prefix
Accepts optional first and last page arguments

`scripts/zip_jpgs.sh`

- Finds matching basename-*.jpg files for the PDF
Creates a zip archive containing those JPGs
Uses ${base}-jpgs.zip by default when no output path is supplied

Notes

- Output files follow the pdftoppm naming convention, typically basename-1.jpg, basename-2.jpg, etc.
If you need different image quality, output naming, or archive behavior, edit the bundled scripts rather than reimplementing the command inline.

概述

使用 poppler-utils 中的 pdftoppm 将 PDF 转换为 JPEG 页面图像，然后可选择将生成的 JPG 文件打包为 zip 压缩包。

环境要求

- pdftoppm 必须存在于 PATH 环境变量中
运行脚本前需安装 poppler-utils 软件包

安装 poppler-utils

- Debian / Ubuntu：

bash sudo apt update sudo apt install -y poppler-utils

- Windows：

- 通过包管理器安装 Poppler，然后将 pdftoppm.exe 添加到 PATH 环境变量中 - 常用选项： - winget install -e --id oschwartz10612.Poppler - choco install poppler - scoop install poppler

- macOS：

bash brew install poppler

标准工作流程

1. 使用 scripts/pdf2jpg.sh 转换 PDF
如需打包，使用 scripts/zip_jpgs.sh 将输出图片打包

bash
./scripts/pdf2jpg.sh input.pdf
./scripts/pdf2jpg.sh input.pdf 2 5
./scripts/zip_jpgs.sh input.pdf
./scripts/zip_jpgs.sh input.pdf /tmp/output.zip

脚本说明

scripts/pdf2jpg.sh

- 若未提供 PDF 路径，则提示用户输入
验证输入文件是否存在
验证 pdftoppm 是否已安装，若未安装则显示 poppler-utils 安装提示
使用 PDF 的基本文件名作为输出前缀，将 JPEG 文件写入 PDF 所在目录
支持可选的起始页和结束页参数

scripts/zip_jpgs.sh

- 查找与 PDF 对应的 basename-*.jpg 文件
创建包含这些 JPG 文件的 zip 压缩包
未指定输出路径时，默认使用 ${base}-jpgs.zip 作为文件名

注意事项

- 输出文件遵循 pdftoppm 的命名规则，通常为 basename-1.jpg、basename-2.jpg 等
如需调整图片质量、输出命名或归档行为，请直接修改附带的脚本，无需重新实现命令
