A generic error occurred in GDI+.

[patness]

I am using Sprite.PDF to convert PDF to images. It is working locally (purchased the component)... but on the server I am getting this error...

Any ideas?


Here is the line where the exception occurs:
var img = doc.SaveAsImage(pageCount, PdfImageType.Metafile);

(This is executing in a controller in an asp.net MVC app)

This error is resolved by changing this line:

doc.SaveAsImage(pageCount, PdfImageType.Metafile);

into this:

doc.SaveAsImage(pageCount, PdfImageType.Metafile, 150, 150);

(Basically, the DPI is required on the server. If not specified the error is thrown)

I'm getting the same error but using Spire.Doc to convert a docx to pdf using Document.SaveToFile(). The exception is exactly the same, but that API doesn't seem to have a way to specify the DPI for the conversion, not sure if that even applies when converting to PDF. Any ideas?

Hi,

Thanks for your inquiry.
Please first try to use the latest Spire.Doc Pack(hot fix) Version:7.11.1 which has more improvements than old version. If the issue still happens, please provide following information for further investigation:
1. The input Word file
2. The full code you were using
3. The type of your project, e.g. console application
4. The framework of your project, e.g. .NET4.0
