Different content when using Aspose Diagram 21.9

I’m using Aspose Diagram 21.9 and found some issue.

With this sample: vdx_sample.zip (173.2 KB)

Using https://products.aspose.app/diagram/viewer to view it, in the 1st page, you can see the image is upside down. But when converting it from VDX to JPG with source code like this:

var diagram = new Diagram(inFile);
var opts = new Aspose.Diagram.Saving.ImageSaveOptions(SaveFileFormat.Jpeg)
{SameAsPdfConversionArea = true};
for(int i = 0; i < diagram.Pages.Count; i++)
 string pageName = "Diagram_" + (i + 1) + ".jpg";
 opts.PageIndex = i;
 diagram.Save(pageName, opts);

On Windows, the image of 1st page is flipped and become like normal. On Linux, the image is the same as original VDX file.

With this sample: sample_vtx.zip (1.9 MB)

Converting the sample on the Linux and Windows environment have different result. Check the 3rd images, there is a different content with 3 Q cards. Here is the attachments show the different: result.zip (1.6 MB)

Please check and help me with these cases.

Thank you.


Regarding the issue of flipped image, would you please share the sample output image that you obtained at your end? We have tested using 21.11 version of the API and did not notice the flipped image issue. Also, please try to use the latest version of the API in both Windows and Linux environments and let us know in case you notice any issues. We will further proceed to assist you accordingly.

Here is my output on Windows: vdx_sample_to_jpg.zip (78.7 KB)

I’ve upgraded the lib to version 21.11 but the issue still there. I’m using Aspose Diagram for .NET.
