针对您遇到的 ValueError: <compression.lzw: 5> requires the 'imagecodecs' package 错误,这个问题通常是因为在尝试使用某个图像处理或数据压缩库(可能是PIL、Pillow或其他第三方库)时,该库依赖imagecodecs包来处理特定的压缩格式(如LZW),但系统中未安装或未正确安装imagecodecs。以下是根据您提供的提示,...

LZW compression 是压缩文件,这样的话输出的文件会压缩的小一些,占用的磁盘空间相对较少。Uncompressed 是不压缩文件,输出的文件占用的磁盘空间相对较大。 选择 LZW compression的话,理论上压缩会使输出的图色彩有损失,但实际使用中感觉不到差别,输出的图质量也不错,一般都会选择 LZW compression 进行...

How LZW compression works The LZW compression algorithm reads a sequence of symbols, groups those symbols into strings and then converts each string into codes. It takes each input sequence of bits of a given length -- say, 12 bits -- and creates an entry in a table for that particular ...
LZW compression is fast. LZW is a fairly old compression technique. All recent computer systems have the horsepower to use more efficient algorithms. Royalties have to be paid to use LZW compression algorithms within applications (see below). ...
