bdicompression's Issues

VG_

Hi,

Does existence of VG_ directives in the script is necessary? I mean, my code did not compile with this directive. I removed all VG_ in the code and it compiled successfully. Is this a problem?

The question of decompression

1.In the code, delta uses unsigned number, how to determine positive or negative during decompression ?
2.Decompression process two base how to determine which one to choose
Thanks
