Working with vector graphics in .NET
Růžička, Filip ; Brožek, Jiří (advisor) ; Hanzlík, Petr (referee)
Current version of the Microsoft .NET Framework (4.6) provides access to the basic functionality of GDI+ (Graphical Device Interface) with more than fifty of code elements (classes, interfaces, structures, enumerated types, and delegates) contained in the System.Drawing namespace. Many advanced functions are then offered in other three nested namespaces, namely Drawing2D, Imaging and Text. This work demonstrates on a complex example using of a selected set of these library functions and compares their output, time and memory requirements with its own parameterizable implementation of the corresponding planar geometric shapes, antialiasing techniques and filling closed areas. The goal of this work is to create an application - a simple SVG format (Scalable Vector Graphics) viewer - which will be able to interpret SVG file commands in a graphical user interface by both of the above methods and for each of them to provide information about the computational complexity, on the basis of which we can show the appropriateness of using one or the other approach, library functions or user-defined functions with the possibility of further optimization.
