Re: [isugamedev-devel] imagelib

[Ben S. <bs...@vr...>]

i would tend to agree. most uses of the image loading library would 
probably be through C++. thus we'd want to make sure that the library was 
well design from the standpoint of using it through C++.

however, i also agree that the image lib should probably be 
distributed/used as a DLL which i believe is why chad wants a C api. 
regardless we will need a C api to access the code in the library, but we 
could do it as just one simple call to get a class and write the 
application code using interfaces ... ie:

// assume getImageMgr is in the DLL and is really being called using a 
// function pointer obtained through GetProcAddr(..)
ImageManager* mgr = getImageMgr();
Image myImg;
mgr->load( "myimage.pcx", img );

cheers,
