Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Seems pretty straightforward at a glance:

  • have a typical canvas inside of a canvas setup that allows to pan and zoom

  • the inner canvas has an image with the picture

  • place Visible circle widgets with opacity set to 0 (if you need hundreds of these - store the 2d vectors in a data table along with the relevant image)

  • clicking circle widgets changes their opacity

When it comes to circle widgets, it may be worth looking into creating a material rather than having one or even a bunch of images of different sizes. You will be scaling those up and down (if you need the zoom feature) so expect quite a bit of loss in quality. A material that draws a smoothly anti-aliased circle should work much better here.
