Can we specify bokeh exported png file size / resolution?

Question

With Python Bokeh export_png function, we can export an object to png file. However, I cannot find any way to specify the resulted png file size / resolution.

I found that I used the same code and got different png files in Windows and Linux. In Windows, the resolution is much lower.

I understand we can use export_svgs() to have better figure file. But compared with export_png(), export_svgs() has many limitations. We cannot use export_svgs() on div, column or row objects.

In recent enough versions, export_png accepts width and height parameters:

If they are not available in your current install then you will need to update your Bokeh installation to something newer.
