Aspose.OCR for .NET 1.9.0 发布,Aspose.OCR for .NET 是一个光学识别组件,可在 ASP .NET 的 Web 应用、Web 服务和应用程序中增加 OCR 功能,提供了简单的类用来控制识别任务,支持 BMP 和 TIFF。

改进内容包括:

  • You can now set thresholds for a template, template page, and for a specific template element. 

  • The threshold is usually set to an acceptable higher average value before initializing the OMR procedure to determine the amount of pixels (as a percent) required before a field or a mark is considered checked or filled. 

  • This release also supports equal spacing between the markers. 

  • This enhancement has been made for the OmrEngine to accommodate markers that are equally distributed on the OMR template.
