Problem extract sprites (Unsupported compression method 3) #35

Closed AngelDevIndie closed 11 months ago

AngelDevIndie commented 11 months ago

I have a problem when I extract sprites. Prompt shows this message "Unsupported compression method 3"

The AGS is version 3.6.1.8 and the utils is the last commit.

AGS commit 028dbe1bb3d74e78affd982488f1b9a0bac3068d added a new compression method, deflate, which is the same algorithm used by the aged zip format, so i highly doubt it's more effective than the existing lzw or rle algorithms - especially given that deflate isn't tuned at all for media. either way, this new format was added 1.5 months ago so it's hardly a surprise we don't support it yet. anyway, thanks for bringing this to our attention.

your testcase (thanks for it) is now properly unpacked by agsprite using git master.
