OCR Problem in Web API

Post by jloizagah » Thu Jan 20, 2022 4:57 pm

Hello. We are programming a REST Web API (.Net) to perform OCR and extract information from PDF's. In a Desktop project it works fine. In a local environment, Web API works fine also (localhost), but when we try it in production environment, we have an error just in this point:


if (gdPicturePDF.OcrPages("*", 0, "spa", basePath, "", 200) != GdPictureStatus.OK)
{
status = gdPicturePDF.GetStat();
gdPicturePDF.CloseDocument();
gdPicturePDF.Dispose();

throw new Exception(string.Concat("Error OCR. Error: ", status.ToString()));
}

and the status error is "Aborted". We have test it with a lot of PDF's, so the pdf file is not the problem. I am using Gdpicture 14.1.0.106.

Thank you for confirming this.

I would therefore be needing a code project to be able to investigate the issue further and reproduce it on my end.

Hello Hugo. Forget all about this issue. I have test our solution in other Server and it works fine. So I suppouse it is a server configuration problem.

Thank you for your time.

Best regards.

Hello Hugo. I have just found the reason of this issue, but I really don't know how to solve it. Rest API Service (or WCF service) fails to permorm OCR in a PDB fie, thrpwing the error "Aborted" if we use in IIS an Application pool diferent from DeafaultApplicationPool. No matter if you create an application pool with the same configuration of DefaultApplication pool. OCR only works with DefaultApplicationPool.

Best regards.
