Programming Projects
Electronics submission form

1. [PDF] Non-Zero Winding Number Polygon Fill
   • SCORES (look for pix.html files in here for results of test cases; my solutions).
   • Please submit your solution via the electronics submission form.
   • Code for creating and saving PNG images: Image.h | Image.c | Makefile
   • libpng is installed under /net/{lib,include} on the lab machines. Change /usr/local to /net in Makefile. Tell the shell where to find the runtime libraries; On Linux:

     export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/net/lib"
     

     On a Mac:

     export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/net/lib"
     

     I put the following in my .bashrc file:

     if [ `uname` == "Darwin" ]; then
     export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/net/lib:/net/local/lib"
     else
     export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/net/lib:/net/local/lib"
     fi
