256色图像的浏览是实用图像处理系统中一项很重要的特技,但颇具难度。本人在从事图文传真系统的研制中精心开发了一个256色图像浏览器,它可以在屏幕的任意位置开一个任意大小的窗口用光标键随心所欲地浏览大幅的256色图像,现详述如下。 256色图像格式文件有多种,但实用中能方便获得并容易处理的图像格式为BMP格式的图像文件,其它格式的图像文件都可方便地转换为这种格式。有关BMP位图文件的详细介绍已有不少文章,这里不再赘述。
The 256 color image browsing is a very important stunt in a practical image processing system, but quite difficult. I am engaged in the development of telefax system in the development of a 256-color image browser, which can be anywhere in the screen to open an arbitrary size window with the cursor keys to browse a large 256-color image, as described below. There are many types of 256 color image files, but the image formats that are easy to get and handle in practical applications are BMP image files. Image files of other formats can be easily converted to this format. There are a lot of articles on the detailed introduction of BMP bitmap files, and will not be repeated here.
