DPI Quality Guidelines

DPI质量指南

Choose DPI based on your use case:

DPI	Quality	File Size	Best For
72	Low	Smallest	Quick previews, draft slides
150	Medium	Small	Web presentations, email
200	Good	Medium	Default - recommended for most
300	High	Large	Print quality, detailed diagrams
600	Very High	Very Large	Professional print, posters

Trade-offs:

Higher DPI: Better quality, larger file size, slower conversion
Lower DPI: Faster conversion, smaller files, lower quality
Sweet spot: 200-300 DPI for most presentations

根据使用场景选择合适的DPI：

DPI	质量	文件大小	最佳适用场景
72	低	最小	快速预览、草稿幻灯片
150	中等	小	网页演示、邮件发送
200	良好	中等	默认值 - 适用于大多数场景
300	高	大	打印质量、详细图表
600	极高	极大	专业打印、海报

权衡要点：

更高DPI：质量更好，但文件更大、转换速度更慢
更低DPI：转换速度更快、文件更小，但质量更低
最佳平衡点：200-300 DPI适用于大多数演示文稿

Batch Processing

Best Practices

最佳实践

Start with default DPI (200): Good balance of quality and file size
Use verbose logging for debugging:
```
-vv
```
shows detailed conversion steps
Test with sample PDFs first: Verify quality before batch processing
Monitor output file sizes: Adjust DPI if files are too large
Batch process efficiently: Use shell loops for multiple files
Enable shell completion: Speeds up command-line usage
Keep poppler updated: Ensures compatibility with latest PDF features
Use absolute paths: Avoids confusion with relative paths
Verify prerequisites: Check poppler installation before bulk conversions
Handle errors gracefully: Check exit codes in scripts

从默认DPI（200）开始：在质量和文件大小之间达到良好平衡
使用详细日志调试：
```
-vv
```
显示详细的转换步骤
先使用样本PDF测试：批量处理前先验证质量
监控输出文件大小：如果文件过大，调整DPI设置
高效批量处理：使用Shell循环处理多个文件
启用Shell补全：加快命令行操作速度
保持poppler更新：确保与最新PDF功能兼容
使用绝对路径：避免相对路径导致的混淆
验证前置依赖：批量转换前检查poppler是否已安装
优雅处理错误：在脚本中检查退出码
