save figure to png with high resolution

Community Support
1

Hi there,

I am trying to use bokeh for making publication quality figures. I can currently export the image to a png file with 600x600 resolution using the preview/save tool, but I need higher resolution images. Could I save image with higher resolution (or in vector graphics format )?

Thanks!

Hi Jian,

We have finally identified a promising technical way forward for implementing this long-requested feature. We are currently working to implement "headless" image generation so that you can create images and export them to SVG, PNG and other formats directly from python without ever having to interact with the browser. There are still some technical pieces to figure out, but our current best estimate is that this will be ready for the Bokeh 0.8 release, which is hopefully, tentatively scheduled for mid-February. You can follow the current progress in these issues:

In the mean time the only solutions I can offer are either create the plot initially at the resolution you want to save at, or add a resize tool to the plot and resize it to the size you want before saving.

Thanks,

Bryan

No, it is still under investigation/development. There is a preliminary PR open that may lead to some capabilities in the near future.
