Spectral K-edge subtraction imaging and wide-field energy-dispersive X-ray absorption spectroscopy imaging are novel, related, synchrotron imaging techniques for element absorption contrast imaging and element speciation imaging, respectively. These two techniques serve different goals but share the same X-ray optics principles with a bent Laue type monochromator and the same data processing algorithms. As there is a growing interest to implement these novel techniques in synchrotron facilities, Python-based software has been developed to automate the data processing procedures for both techniques. In this paper, the concept of the essential data processing algorithms are explained, the workflow of the software is described, and the main features and some related utilities are introduced.
光谱边缘减法成像和宽场能谱 X 射线吸收光谱成像是两种新颖的、相关的同步辐射成像技术，分别用于元素吸收对比成像和元素形态成像。这两种技术的目的不同，但都具有相同的 X 射线光学原理，采用弯曲的劳厄型单色器和相同的数据处理算法。由于人们越来越有兴趣在同步辐射设施中实现这些新技术，因此已经开发了基于 Python 的软件来自动执行这两种技术的数据处理过程。本文解释了基本数据处理算法的概念，描述了软件的工作流程，并介绍了主要功能和一些相关实用程序。
