（1）Jasper库：提供表现图像、色彩（色彩空间定义）和其他相关的入口类。这些类都有很好的接口，通过这些接口程序可以和类对象交互。可以使用这个库来操作图像、导入/导出“各种格式的图像”并执行基本的色彩管理操作。其中核心代码提供：图像类，色彩类，色彩转换类，流类，固定点数字类，Tag值解析类等功能类。（2）内含改库的操作说明手册，方便实用！-(1) Jasper library: to provide the performance of image, color (color space) and other relevant entry class. These classes have a very good interface, the interface through which programs can and class objects interact. You can use this library to manipulate images, import/export " the images in various formats,"　and to perform basic color management operations. The core code provides: Image class, color and the color conversion type, flow type, fixed-point digital type, Tag value of the class of functions analytic category. (2) change the database contains the operating instruction manual, convenient and practical!
