The glyph is produced using image_url. The x,y coordinates specify the location of the NW corner of the image. How to make x,y coordinates specify the center of the image?
Also, how to specify a relative url that would use the http protocol? ‘./foo/bar.png’ defaults to ‘file://…’
ImageURL glyphs supports setting an anchor property:
So, if using bokeh.plotting
renderer = p.image_url(...)
renderer.glyph.anchor = ...
For relative URLs, AFAIK it matters how you open the HTML file. If you open as a file, the relative link will also be a file, but if you open from a server, the relative link will refer to the server. So, as a suggestion, view the file with some lightweight HTTP server (python has one built in).
