One request to make the ZLib-functions from the Library public, so that we have access to it. This is done very simple:

 

Add this line into XTPGraphicBitmapPng.cpp

 

_XTP_EXT_CLASS int ZLibCompress( Bytef *dest,   uLongf *destLen, const Bytef *source, uLong sourceLen)
{
   return compress( dest, destLen, source, sourceLen);
}

_XTP_EXT_CLASS ULONG ZLibCompressBound( uLong sourceLen )
{
   return compressBound ( sourceLen );
}

_XTP_EXT_CLASS int ZLibUncompress (Bytef *dest,   uLongf *destLen, const Bytef *source, uLong sourceLen)
{
   return uncompress ( dest, destLen, source, sourceLen );
}

 

 

 

And these lines into XTPGraphicBitmapPng.h

 

_XTP_EXT_CLASS int ZLibCompress( BYTE *dest,   ULONG *destLen, const BYTE *source, ULONG sourceLen);
_XTP_EXT_CLASS ULONG ZLibCompressBound( ULONG sourceLen );
_XTP_EXT_CLASS int ZLibUncompress (BYTE *dest, ULONG *destLen, const BYTE *source, ULONG sourceLen);

 

That's all and everyone can use the zlib functions without adding them again and again.

could you also add compress2() ?!

Thanks
