Canon Raw format to PDF


#1

I am getting the following error when submitting a Canon Raw image to my rendering code using Aspose.imaging.

Is this format supported? other formats are working fine, like BMP, JPG, GIF etc

Cheers

@martin.t,

I have observed your comments. Can you please share source file and sample code so that we may further investigate to help you out.

The image sample is too big to be attached - You can reference it here - https://drive.google.com/file/d/0B4mKiWobtzofaHVWam0zNTJmNjA/view?usp=sharing

The file is a .CR2 - A Canon Raw photo format.

The relevant C# code fragment is:

var file = new FileBackedMemoryStream(parameters.SourcePath);
var image = Image.Load(file, new LoadOptions { DataRecoveryMode = DataRecoveryMode.ConsistentRecover });

The Image.Load call fails with the exception previously listed.

We are using Aspose.Imaging version 16.12

I can organise for the library to be updated to a later version if required, but there is no point if the file type is not supported.

Thanks,

MartinT
