这是什么问题？

控制台如下：

outFilePath: "E:/technology/OCRLater/SampleImages/09.tif"
outputFormat: TIF
imageProcessingCommand: INVERTED_TEXT

您好，是已经激活了评估版本的key

关于另一个错误，应该是错误提示里的libpath中的文件找不到，这个是相对路径引起的错误

Exception: Invalid bits/pixel

这个异常是什么原因造成的？

不支持的图片位深

这个一般是图片处理命令可能只支持1位深的图片，您用其他的位深就会引起错误

是否有教程指导javascript以及java进行图片处理？
java的方法是否有API文档？

Richard.Ma · Richard.Ma

接口文档见下面的链接，有各个命令的接口使用方法，但是例子是以.net来写的，使用方法相同
