I need to write a C library routines to allow user to process images to get different effects like inverting colors and scrolling vertically and horizontally.

for inverting colors, we need to write a function-
for scrolling vertically and horizontally, we need to write a procedure-

and call these function and procedure in the mainline.

there is already a supplied library to use which contains the routines, we just need to used the library in the program.

tanx a lot!

ask whoever wrote your library how to use the functions, or look around for the documentation (hopefully it exists).

Sounds like an interesting library. What is it called?

Is it called ep100lib by any chance?
