  1. Jianning Yue Wookyun Kho Young Jin Yoon AGL : Animation applet Generation Language

  2. Contents  IPL?  Advantages  Syntax  Development  Examples  Lessons Learned AGL : Animation applet Generation Language

  3. IPL?  IPL is not Image Processing Language  Now this is an A nimation applet G eneration L anguage! AGL : Animation applet Generation Language

  4. Advantages (1/2)  IPL provide very flexible image handling  Provide fundamental operation for image as expression  Rotate (@ operator)  Translate ( ‘ operator)  Scale (^ operator)  Provide animate() function to produce an animated Image  Provide coord type to handle coordinates AGL : Animation applet Generation Language

  5. Advantages (2/2)  Easy to learn  C like syntax and scope  Easily-recognized operator  (^ is power operator from another language)  Productive  Can be exported as an JAVA applet  smaller than GIF Animated Image AGL : Animation applet Generation Language

  6. Syntax : Types (1/3)  Four types in IPL  number  image  coord  bool  Optional declarator in IPL  [] for array definitions AGL : Animation applet Generation Language

  7. Syntax : Types (2/3)  For both  imgA[0] imgA[0~1]  For lvalue  imgA[1+] imgA[1~2+] AGL : Animation applet Generation Language

  8. Syntax : Types (3/3)  For rvalue  imgA[0-]  imgA[1~2-] AGL : Animation applet Generation Language

  9. Syntax : Expr (1/4)  Basic image operator  imgA = imgA @ numA; // rotate operator  imgA = imgA ^ numA; // scale operator  imgA = imgA ` coordA; // set operator  imgA = imgA : numA; // alpha operator  imgA = imgA $ imgB; // concat operator AGL : Animation applet Generation Language

  10. Syntax : Expr (2/4)  Basic bool operator  booA = numA > numB; // gt operator  booA = numA < numB; // lt operator  booA = numA >= numB; // ge operator  booA = numA <= numB; // le operator  booA = numA == numB; // eq operator  booA = numbooA != numbooB; // neq  booA = !booA // not operator AGL : Animation applet Generation Language

  11. Syntax : Expr (3/4)  Basic arithmetic operator  numA = numA * numB; // multiply  numA = numA / numB; // division  numA = numA % numB; // modulo  numA = numA + numB; // plus  numA = numA - numB; // minus  For coord, there is no operation. However we can still handle this. How? AGL : Animation applet Generation Language

  12. Syntax : Expr (4/4)  For coordination  cooA = (xof(cooA),numA);  cooB = (numA, yof(cooA));  By providing xof() and yof(), we can still maintain flexibility without any complexibility! AGL : Animation applet Generation Language

  13. Syntax : Stmt  Providing while, if statement just as almost same as C ’ s statement definition.  Except using {} for single statement.  You can define a function using defunc keywords.  defunc foo (number A, number B) number C { C = A + B; }  Providing return, break, continue statements.

  14. Development  Task Distribution  Architecture Overview  Implementation  Test and Debug plan AGL : Animation applet Generation Language

  15. Task distribution Parser Parser Lexer Lexer Young Young Jin Yoon Jin Yoon Walker Walker Animation Animation Wookyun Kho Wookyun Kho Module Module Module Module & Jianning Yue Jianning Yue Integration Integration Test Test AGL : Animation applet Generation Language

  16. Architecture Overview  Used UML Class Diagram AGL : Animation applet Generation Language

  17. Implementation (1/3)  ANTLR  Parser  Lexer  Walker  Animation Module  Animation Displaying Engine  Animation Applet Code AGL : Animation applet Generation Language

  18. Implementation (2/3) Token Input AST Lexer Parser AST Walker Stream Stream Create/Invoke/Fetch/Set IPL Object Non Image Output Symbol Table Exception Handling Java 2D Java 2D Animation module Applet module Display Display Images Images Save Save Animation Animation Information Information AGL : Animation applet Generation Language

  19. Implementation (3/3)  Animation Applet  If you do “export”, you have to specify the filename.  Ex) export to “IPLoutput.ipl” <applet code=IPLApplet.class width=1024 height=600> <param name="fps" value="20"> <param name="ipl" value="IPLoutput.ipl"> </applet> AGL : Animation applet Generation Language

  20. Test and Debug Plan  Test plan  Debug Plan  Control statement  Make debug flag and debug() for debugging  Function call  Using assert()  Static scope  Using eclipse IDE  Static image display  Good for debugging  Image rotation  Image scale  Image rotate  Image set  Image alpha  Image animation  Image Array animation  Combined Image animation AGL : Animation applet Generation Language

  21. Examples (1/4)  Basic Arithmetic, Coordination Results: (1,3) 4.0 AGL : Animation applet Generation Language

  22. Examples (2/4)  Static image sshield.jpg sshield.jpg AGL : Animation applet Generation Language

  23. Examples (3/4)  Animated image strawberry.jpg strawberry.jpg AGL : Animation applet Generation Language

  24. Examples (4/4)  GIF animation AGL : Animation applet Generation Language

  25. Lessons learned  Things learned from Software Engineering actually works!  Still, Team management.  Especially for Time management  Hard to find implement together!  Need more fair distribution to learn  To learn something, everybody should do every procedure together that we have.  Clarify how compiler works!
