I am using c# to recognize pictures and export the result using xml file. I need character color as well as background color in my project, so I tried to set XMLExportParams.WriteCharFormatting to true and XMLExportParams.WriteCharAttributes to XMLCharAttributesEnum.XCA_Extended. However, I can only get font color in this case, and I have tried ohter XMLExportParams but in my exported XMLs, I still cannot get background color attribute. How can I set them in my program to get it (background color of line/word/etc)? Thanks in advance.
