Color pdf Identification error

Aspose.PDF Product Family
1
We got a issue while processing PDF though aspose components.
Version used: 12.0.0.0
1. Not supported image type

We have to identify color PDF. When we try to identify ColorType of PDF, we are getting an error: "Not supported image type". Heard this issue was with previous version, and fix was in place. But still we are getting this error.

StackTrace we got:

at Aspose.Pdf.XImage.Save(Stream stream, ImageFormat format, Int32 resolution) at Aspose.Pdf.XImage.GetColorType() at Aspose.Pdf.Page.[1]() at Aspose.Pdf.Page.get_ColorType()

Debugging shows its "NotImplemented" exception.

Please advice how to get rid of this exception, as its very critical at this moment.

Hi There,

Thanks for contacting support.

I am afraid that you are using a quite old version of the API whereas it is always recommended to use the latest version which is 17.3.0. I have tried to get ColorType from a sample PDF file at my side and I did not notice any issue. I have used latest version of the API and following code snippet.

Document doc = new Document(dataDir + “sample.pdf”);
Console.WriteLine(doc.Pages[1].ColorType);

Please try using the latest version and in case if you still face any issue we will really appreciate if you please share a sample code snippet along with sample document. It will really help us in testing the scenario in our environment and get back to you accordingly. We are sorry for the inconvenience.

Best Regards,

I have tested with aspose.pdf 17.6 version I am getting the same error for one particular pdf file. Could you check the file selenium-recipes-in-csharp-sample.pdf (879.1 KB). With latest version.
