Built-In Functions

  • __print( str );
  • img = read_in( filename, ext );
  • write_out( img, filename, ext );
  • px = get( img, x, y );
  • set( img, x, y, px );
  • i = getc( px, “color” )
  • setc( px, “color”, i )
  • dimensions( img, “width” );

Sample Program

function void main () { img cat; cat = read_in( "cat1", "jpg" ); int w; w = dimensions( cat, "width" ); int h; h = dimensions( cat, "height" ); pixel p; p = [255,255,255,100]; int i; int j; for (i=0; i<w; i++) { for (j=0; j<h; j++) { set( cat, i, j, p ); } } write_out( cat, "blackout", "jpg"); }

Sample Program

function void main () { img cat; cat = read_in( "cat2", "jpg" ); int w; w = dimensions( cat, "width" ); int h; h = dimensions( cat, "height" ); pixel px; int val; int i; int j; for (i=0; i<w; i++) { for (j=0; j<h; j++) { px = get(cat, i, j); val = getc( p, "b" ); val = val + 50; if ( val > 255 ) { val = 255; } set( px, "b", val ); } } write_out(cat, "cool_cat", "jpg"); }

Potential Programs

  • Cropping
  • Defining a set of photo filters
  • Enhance photos
  • Combining images, make collages

Lessons Learned

Set Firm Deadlines In the same vein as “Start Early” make and set hard deadlines. We aimed to meet once a week and had deadlines but as the semester went

  • n, homework and exams and other things took

up more time. We ended putting things off and missing goal dates which made finals week crunch time.

Lessons Learned

Thoroughly Plan Your Language This one is somewhat difficult to accomplish. Though we thought we had thought through our language well, when it came to development we ended up spending a lot of time going back and modifying/revising previously written code. We wasted a lot of time doing this.
