Original Post
I downloaded some C++ source code off of the internet for a fast bitmap scaling routine, and it uses assembly instructions for the scaling. I know NOTHING about assembly, but there seems to be a problem with the command ALIGN 16. The entire program will compile just fine except for those lines. SNIP: I think you get the idea. Anyway, I've tried searching for "ALIGN 16" and "ALIGN 16 C++" and whatnot, but no help. Is there some include file I need, or is there an equivalent statement that I can use instead? I'm using Borland C++Builder for my program. Thanks. By the way, in case this doesn't work out, any suggestions for some fast bitmap scaling routines (link to source) would be appreciated.
