For a Webserver I need to create the png graphics format.
I want to use as little external components as possible.
Has someone experience with the zlib format or specification?
Can it be used without allocating memory?
Or with a given memoryblock for operation?
zlib's compress2 operates on memory blocks that you give it, but I am not sure whether it allocates
temporary buffers. Note that I tried FPC's zlib but it crashed on Windows. Instead, on Windows, I
am linking to
{$linklib Libs/mingw/libz.a}
{$linklib Libs/mingw/libmsvcrt.a}
{$linklib Libs/mingw/libgcc.a}
On the Mac, zlib is part of the system software.
