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"

Find White Pixel

Hi. I'am trying to make something like this: I want to find if there are any white pixels on a screen, and if it's true, I want to color everything (all the pixels) green, and if there are only black pixels, I want to color everything red. I have a multiply node with two inputs, that gives black color by default, but when dot in a center crosses circle, some pixels become white, so I want to color everything green when even one pixel is white. For now, it colors white pixels to green and black pixels to red. Maybe I should use "for" node, but I can't find it.alt text

Sorry for bad English.
