Convert Visio Diagrams to PNG using Aspose.Diagram for .NET - output images are not correct

msindia · January 29, 2020, 9:59am

Hi Aspose,
Currently we are using Aspose.Diagram 18.10 and we wanted to upgrade to 19.11. If we replace this dll, some images do not render correctly.

Problem 1 :
Input Visio: Extra Image shown_Old.zip (88.3 KB)

Output Image:
Version 18.10 : Extra Image shown_Old.PNG (17.9 KB)

Version 19.11 : Extra Image shown_New.PNG (21.3 KB)

Problem 2 :
Input Visio: Extra Space shown_Old.zip (76.1 KB)

Output Image:
Version 18.10 : Extra Space shown_Old.PNG (3.3 KB)

Version 19.11 : Extra Space shown and Question mark icon_New.PNG (7.0 KB)

Problem 3 :
Input Visio: Icon Position changing_Old.zip (41.6 KB)

Output Image:
Version 18.10 : Icon Position changing_Old.PNG (1.4 KB)

Version 19.11 : Icon Position changing_New.PNG (1.4 KB)

Problem 4 :
Input Visio: Question Mark Icon position change_Old.zip (44.1 KB)

Output Image:
Version 18.10 : Question Mark Icon position change_Old.PNG (4.8 KB)

Version 19.11 : Question Mark Icon position change_New.PNG (4.8 KB)
Sample Code:

string strInputPath = @"C:\vj\2019\Visio Issues\Old";
			string strOutputPath = @"C:\vj\2019\Visio Issues\New\";

			string[] files = Directory.GetFiles(strInputPath, "*.vsdx");

			foreach(string strFile in files)
			{
				Diagram vdxDiagram = new Diagram(strFile);
				ImageSaveOptions opt = new ImageSaveOptions(SaveFileFormat.PNG)
				{
					SmoothingMode = SmoothingMode.HighQuality,
					CompositingQuality = CompositingQuality.HighQuality,
					InterpolationMode = InterpolationMode.HighQualityBicubic,
					PixelOffsetMode = PixelOffsetMode.HighQuality
				};
				vdxDiagram.Save(strOutputPath + Path.GetFileNameWithoutExtension(strFile) + ".PNG", opt);
			}

We are waiting for your reply and support.

Thanks.
