Error when using exportgraphics function to save large vector graphics with transparency

When I tried to save a large vector graphic with transparency information using the exportgraphics function on my PC, an error occurred.

MATLAB version: 9.12.0.2529717 (R2022a) Update 8

Operating system: Microsoft Windows 10 Pro Version 10.0 (Build 19045)

Java version: Java 1.8.0_202-b08 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

After plotting a large 3D vector graphic with complex perspectives and transparency relationships in a figure, I attempted to run the following code to save the figure:

exportgraphics(gca, 'picture1.emf', 'BackgroundColor', 'none', 'ContentType', 'vector')

However, the program threw an error.

The error message was:

Problem while processing in an OutputHelper. java.nio.file.NoSuchFileException:

I tried running MATLAB as an administrator and on a PC with higher memory, but the error persisted, and the error message remained the same. In addition, I checked the available storage space on my computer, and I have at least 390 GB of free space.

When I saved the same figure without transparency information as an image (using

exportgraphics(gca, 'picture1.emf', 'BackgroundColor', 'none', 'ContentType', 'image')

), the exportgraphics function worked correctly.

Furthermore, I plotted a smaller image and tried again to save it using

exportgraphics(gca, 'picture1.emf', 'BackgroundColor', 'none', 'ContentType', 'vector')

, and the result was correct.

So, it seems that the exportgraphics function may not support saving larger images, or is there another reason?

你可以把你的图存为fig格式上传过来以便我复现此问题吗？
