摘　　要：Tina系统是用C语言编写的专门用于计算机视觉与图像处理研究的Unix实验平台。利用Tina平台生成人机交互的图形界面,编程方便、形式简洁、功能丰富;不足之处是Tina系统不提供彩色图像的显示与处理功能,对不同格式图像文件的读写与转换的支持也有限,因此这些功能有待增强。本文首先采用建立中间数据结构的方式实现了多种常用图像格式的相互转换,然后分析灰度图像显示过程的函数调用关系,利用最底层的Xlib库函数在Unix下实现了彩色图像的显示,使彩色图像的处理得以可能。Tina platform is written in C language as a Unix test bed for computer vision and image processing research.With Tina platform,tedious interface programming becomes a simple and convenient job to produce application softwares of powerful functions and in a tidy and straightforward style.However,it＇s a pity to see that Tina never provides functions for color images to be displayed,let alone to be process;besides,Tina offers limited functions to support multiple format conversion among image files,therefore,a function enhancement is expected.In this paper,the conversions among seven popular image formats are first implemented by creating a data structure as the medium among those formats;then an analysis on function callings in the process of gray image displaying is made in light of Tina＇s GUI development principles.Finally,the displaying of color images is achieved under the Unix system using the lowest level of X library functions,thus making a further color image processing be possible.
