Image Quality worse after upgrading aspose to version 15.10.0


After upgrading from aspose version 14.8.0 to aspose version 15.10.0 we noticed the quality of our images is worse.

After closer inspection of the xml inside the document I noticed the images get the nodetype drawing instead of picture, and think this could be the root of the problem.

We don’t do anything exciting when merging our document with an image.

Private Sub ImageFieldMerging(ByVal e As ImageFieldMergingArgs) Implements IFieldMergingCallback.ImageFieldMerging

If e.FieldValue IsNot Nothing AndAlso e.FieldValue.GetType() IsNot GetType(DBNull) Then

Dim imageStream As New IO.MemoryStream(CType(e.FieldValue, Byte()))

e.ImageStream = imageStream

End If

End Sub

Is there anything we can do on our end to regain the quality of the images?

In attachment I’ve added two documents, one with the old version of aspose one with the new version as a reference to the quality.

With kind regards,
