DescriptionTURTLE.LIB is a library for drawing turtle graphics, as in the Logo programming language or Python's built-in turtle library. Basically, you control a pen or "turtle" that can move forward, backward, or turn left or right by some angle, and as it moves, it draws on the screen. Turtle graphics are more of an educational tool than something with practical use, but they can be fun to play around with.
ALINE.LIB is a library that can draw anti-aliased lines. Like the other AA line library on this site, it is an implementation of Xiaolin Wu's line algorithm. However, this one allows for different colored lines, and simulates translucency for edges when overlapping other graphics, rather than always fading the edges to black. That said, it is still quite slow, and is most likely slower than the other due to these additional features.
Since TURTLE.LIB depends on ALINE.LIB, both have been packaged together.InstructionsTo use turtle library:
