Abstract
Special effects show for images is applied in the field of computer technology
widely. The Windows screen savers use a variety of image special effects which feel
refresh. This paper describes the basic principles and methods of image special
effects show based on VC++. The algorithm of the effect shows including scanning
special effect show, bar special effect show and mosaic special effect show are
studied. This paper also designes two special effects——Gradually changing blinds
and corroding bubble. The implementation of the display algorithm and software
interface designment are realized in this paper.
The digital image processing interface is based on Microsoft Visual C + +
6.0 MFC multi-document image processing programming interface, to achieve.
Bmp format for image browsing and editing, import and export, image effects showe
d that edge detection, rotate and flip images, pictures enhance the optimization, as w
ell as print output picture. Is a function of the digital image than the simple manage
ment interface, to achieve. Bmp format images of the operation. The interface contai
ns two parts: interface and the main interface to start.
BMP file is a Windows operating system and support the recommended image
file format, is a memory or display the compressed image data is not directly based
on digital archiving of file formats, BMP files are generally divided into four parts: t
he first bitmap documents, BITMAPINFOHEADER, color table, the bitmap data. At
the same time, BMP file formats and can be divided into DIB format DDB, DIB for
mat which has nothing to do with the equipment of the BMP files, a strong GM. Win
dows in support of the DIB to visit a number of important function, but are not pack
aged in the MFC, where we have a package type DIB, the DIB includes Ventura nee
ded to deal with members of the basic variables and member functions, and such a b
ase class for other types of derivatives, the realization of the procedure maintenance
and transplantation, and thus the use of object-oriented way of programming the visu
al image.
