1 year ago Just happened to come across this as I was looking over the code - I think this might be fixed by a pull request that I opened last week, #9. In short, there's an error for the im.crop arguments when the width of a casaviewer image is greater than the height. If this gets fixed up I think that would solve this problem.
Weblog generation can fail inexplicably sometimes:

The workaround for this is to 'rm -rf ~/.casa/viewer', removing all the saved configuration regarding the casaviewer on your system. Then the weblog can run without a problem. however, it would be good to be able to run this without needing to occasionally nuke the viewer settings. Perhaps exporting to fits and using matplotlib for drawing the images is a better way in the future.
