CMYK图像的TIFF格式

为满足印前和艺术设计过程中的图像处理的需要,介绍一种基于CMYK(青-品红-黄-黑)颜色空间的图像在TIFF文件中的存储,以及对此类图像的通用处理方法。通过对TIFF文件内部结构的解析,了解如何才能准确地对一幅CMYK图像进行描述、存储和处理。另外,文中还给出使用libtiff函数库处理TIFF文件的样例。

TIFF Image File Based on CMYK Color Space

In order to meet the demand of image-processing during the process of pre-printing and art design,this paper introduces a way of processing an image based on CMYK color space and stored in a TIFF image file.We will describe,store and process an image based on CMKY color space through a thorough look into the structure of the TIFF image file.In addition,we provide an example on how to process a TIFF image file with the help of libtiff librarys,which has a great many functions but still are easy to use.We can get an ideal result that equals to photoshop's.Using libtiff librarys may be a good choice.
