not support native; Bzip2 command is provided in Linux for ease of use. Disadvantages: the compression/Decompression speed is slow; Native is not supported. Application Scenario: Suitable for scenarios where the speed requirement is not high, but the compression ratio is high, it can be used as the output format of mapreduce jobs; or the output data is large, after processing, the data needs to be compre
This section roughly summarizes the compression and decompression methods for various formats of compressed packages in linux. However, I have not used some of the methods.

-15 is 0-7 twice times.Luminance Index 1 corresponds to (-12,-4, 4, 12);3. The 2-bit pixel index is 0, so the luminance supplement is-12. The color value of this pixel can be obtained (0-12, 34-12, 255-12), i.e. (0, 22, 243).The four mobile device GPUs support ETC1, so non-transparent textures on various Android devices can be in the ETC1 format, unfortunately ETC1 does not support transparency. For transparent textures, on Android devices, you can split RGB and alpha onto 2 ETC1 textures, which
In the Linux operating system, the compression and decompressing of the *. zip, *. tar, * .tar.gz, * .tar.bz2, *. tar. xz, *. jar, and * .7z formats are as follows: .tar.gz.tar.bz2Zip Format Compression: zip-r folder target file name. zip [original file/directory name] unzip: unzip folder original file name. zip Note: The-r parameter indicates recursion.Tar forma
