How to plot a Raster image without the white border?

HoloViews

I’m trying to save out some images with customized overlaps and colors. However, they all plot with a thick white border, which is a problem because it gets saved out that way as well.

here’s some example code,:

test_img = np.ones((50,50))
hv.Raster(test_img).opts(xaxis=False,yaxis=False,cmap=‘gray’,aspect=‘equal’)

and here’s the output (notice the white border):

image
image717×298 4.23 KB

is there some border=False type command to turn it off?

If you use bokeh backend instead of matplotlib, there is an option border=0, you may also use toolbar=None, xaxis=None,yaxis=None.
By the way, in that case when you plot with bokeh the image is out of the frame, but if you use hv.save, your image will be saved correctly.
