Stream 如何获取原始jpeg数据（但没有元标记/专有标记）
我想获得原始jpeg数据-没有元数据。 看jpeg“标准”我很困惑 我对标记“树”的理解有多正确 这是我的阅读材料： 除了SOS（0xFFDA），您可能还需要以下功能： 0xFFDB DQT量化表Stream 如何获取原始jpeg数据（但没有元标记/专有标记）,stream,jpeg,hex,exif,Stream,Jpeg,Hex,Exif,我想获得原始jpeg数据-没有元数据。 看jpeg“标准”我很困惑 我对标记“树”的理解有多正确 这是我的阅读材料： 除了SOS（0xFFDA），您可能还需要以下功能： 0xFFDB DQT量化表 0xFFC4 DHT Define Huffman Table有一个相当合理的“JPEG剖析”，它向您展示了如何使用grep从JPEG文件中提取JPEG标记和节，例如对于SOF标记： xxd -c16 -g1 -u testimg.jpg | grep --color=always -C2 &q
