摘要
JPEG和GIF格式图像在保证图像显示质量的条件下同时兼有较高的压缩率,从而得到了广泛的应用.用JPEG和GIF格式图像替代没有任何压缩的BMP格式图像在VisualC++中的应用,降低了程序的时空开销.以JPEG格式图像的显示为例,介绍一种利用IPicture的COM接口显示此格式图像的简便方法及实现,并给出了相应的显示结果.
JPEG and GIF format images have broad applications because they have good vision quality and high compression ratio. JPEG and GIF format images substitute for BMP format images without any compression in Visual C++, which can decrease the expenditure of program time and space. Taking the display of a JPEG format image as an example, a simple method is presented for using COM interface of IPicture to display images. Corresponding display results are given.
