I want to make a library for Qbasic, and I want to have some kind of image loader in it. I want to load as much types as images as possible .
But, the only manner I know to get this in a library is to compile the Qbasic code to an OBJ file, an include that in the library. But I want it to be as fast as possible also.
So, is it possible to make it faster (for example by using another programming language)?
Assembly language is the way to go if you want to make potentially faster libraries than native QB code. You could also use something like QuickC, but it won't give you quite the same performance and will likely also be larger.
