SVG export gradient

Aspose.Diagram Product Family
1

Hi



I am investigating possible API for converting Visio files to different formats and hence I am using an temp license.

We currently have an VBA which exports the files (Using Visio 2007).



But after creating the output, i noticed that the gradient “background” is wrong on the Aspose generated files. I am uncertain if this is an actual error in the aspose libraries, or if there is a setting i can set to get it to generate correctly.



I am not the one creating the visio files.



Using the following code produces almost the same result as the VBA code source included (path must be adjusted) but the gist of the code is:



var fi = new FileInfo();

var d = new Diagram();

d.Save(fi.Name.Replace(“vsd”, “svg”), SaveFileFormat.SVG);



Aspose.Diagram is installed through nuget and using version 6.6.0.



In the attachment I have included the visio file, and the output formats.



Files with double extension .vsd.pdf is the VBA versions, and hence the files with a single extension is the aspose generated.

I just wanted you to know because the background has changed between 6.6.0 and 6.6.1 (the hotfix)

In 6.6.0 the background was gradient but just from left to right.
In 6.6.1 the background is all black now.

I am still seeing this similar issue in the latest version of Apsose Diagram for Java. Has this been fixed? Gradients are still not working.

Hi

I can’t seem to find a download link for the files attached to the original post. I am revisiting this subject and need to check that this is acceptable. Where are they?

Found another issue (but will log it on a new ticket)
