Image conversion software design, has some of the basic operation of the image, including view pictures, enlarge, narrow, a picture before, after a, image transformation and new screenshots and other functions. Reuse code by using QT. The software is easy to operate, clean interface. In the embedded Linux system environment design of image transformation based on QT and has more practical value. This design is a GUI design using QT technology in Linux and windows, the realization of a graphical interface using QTCreator software programming, to complete a simple image transforming design. The design of the QT integrated development environment based on, programming, has the advantages of small volume, support playback function format conversion, the system takes fewer resources, support a variety of commonly used format using the function interface system and Can also achieve code reuse, to achieve cross platform effect. The development of design in the Windows 7 system and Ubuntu12.04, which is developed by C++ language, in the Qt 4.7.4 development platform. Through its development, in-depth understanding of QT software development process and its powerful functions for later reference, user.
