Fast Drawing and Bitmap Graphics This chapter presents fast drawing techniques‚ animation using bitmaps‚ and color palettes. First‚ fast drawing using the exclusive-or (R2_XORPEN) and the exclusive-nor (R2_NOTXORPEN) ROP2 codes is explored. Then‚ fast drawing using the “backing store” technique is discussed. Bitmaps are used in the backing store technique‚ and their use is introduced. After this‚ an example of creating animation using bitmaps is presented. Finally‚ the device independent bitmap

Abstraction refers to the ability to make a class abstract in OOP. An abstract class is one that cannot be instantiated. All other functionality of the class still exists‚ and its fields‚ methods‚ and constructors are all accessed in the same manner. You just cannot create an instance of the abstract class. If a class is abstract and cannot be instantiated‚ the class does not have much use unless it is subclass. This is typically how abstract classes come about during the design phase. A parent

Abstract – Image Processing Algorithms are the basis for Image Computer Analysis and Machine Vision. Employing a theoretical foundation – Image Algebra – and powerful development tools – Visual C++‚ Visual Fortran‚ Visual Basic‚ and Visual Java – high-level and efficient Computer Vision Techniques have been developed. This paper analyzes different Image Processing Algorithms by classifying them in logical groups. In addition‚ specific methods are presented illustrating the application of
