Using ImagePluginPNG to (un)compress a memorybuffer

[Rescator]

Have to give thumbs up to the last two posts here. zlib.lib is the best solution and I really wish PureBasic had that as it's default compression. (4.5+ maybe?)

Btw! Do you really need to go into usr/lib/ ? I kinda assumed that zlib.lib was distributed with all PureBasic versions on all platforms?

PureBasic uses the deflate and inflate functions (according to the PNG specification) for its PNG ImagePlugin. So the zlib library is most probably part of each distribution.

The solution from ts-soft doesn't work anymore for PB 4.50 Beta 4?! Can anyone confirm this and hopefully say what I can do to fix it?

And by the way:
For decompression I alway get -3 as a result but the compression worked fine.


Edit:
Sorry, I'm not fully sure but I think it was an error on my side.
