Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

准备 CR2 源文件

  • 在导入前用相机软件确认 CR2 的原始位深(12/14 位)以选择合适的导出位深
  • 清理 CR2 中多余的连拍标识或静态缩略图以避免误嵌入元数据
  • 如果需要精确白平衡,先在 RAW 解码阶段应用校正再导出 RLE
  • 对高 ISO CR2 执行降噪预处理以减少 RLE 中行程长度编码的低压缩效率
  • 保留原始 CR2 备份以便未来需要重跑不同去马赛克或色彩流程

RLE 输出与存储策略

  • 评估是否需要 16 位输出:选用 16 位可保留更多动态但会显著增大 RLE 大小
  • 将 RLE 与旁注 ICC 或 EXIF 文件一并打包,确保目标设备有办法读取配套元数据
  • 对纹理丰富照片考虑先微缩到目标展示尺寸以降低 RLE 文件体积
  • 使用 ZIP 归档批量 RLE 文件以便在传输设备间保持完整性
  • 为嵌入式设备生成按行对齐的 RLE,以匹配设备解码缓冲区对齐要求

验证与兼容性测试

  • 在目标显示设备上核查色彩:将带 ICC 的输出与不带 ICC 的输出进行比对
  • 打开 RLE 输出于目标渲染引擎,确认行解码顺序与像素排列(RGB 或 BGR)匹配
  • 检查边缘细节与去马赛克伪影,必要时尝试不同去马赛克算法重跑转换
  • 验证是否需要 alpha 通道:若需要,从 CR2 的掩码或后处理生成并核对透明表现
  • 将样本 RLE 用目标嵌入式查看器加载,检测内存与解码速度是否满足实时需求

隐私与性能优化

  • 在浏览器端完成所有解码与编码以确保 CR2 图像不被上传到远端服务器
  • 批量转换分批执行(20–50 张)以避免浏览器内存峰值导致任务失败
  • 关闭无关扩展以减少内存占用并提升去马赛克步骤的稳定性
  • 如需更快输出,先降采样 CR2 到目标像素尺寸再导出 RLE
  • 完成后及时下载并清理本地内存以防数据泄露或缓存占用

Fast Processing

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
