Recently I was working with Social Networks in Python using networkx library to analyse posts from a given hashtag for our client. I am a Data Scientist working in a startup in Brazil.
In case you are wondering why I used a nested With inside the Module instead of making img a module-variable too: it's because by the time doIt is evaluated, the local module variables will have been cleared, so I need to substitute the rasterized expression directly into the doIt function, This is what I have so far (includes only the preview code, not the uploader): button = Button[Ĭolumn[ Before uploading, I would like to show a preview of the image, to reduce the chance of something going awry before contacting the server. I would like to create a palette button that will upload the current notebook selection as an image.
