{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"color() function is not thread-safe","articleBody":"The following code:\n\n```\n    for(int j=0; j \u003c dimention; j++) {\n      color current = ledImage[i].pixels[j];\n      ledImage[i].pixels[j] = color(red(current), green(current), blue(current)); //multiply color correction here\n    }\n```\n\nWas acting as a place holder. The plan was to multiply the Red, Green, Blue by color correction values for each pixel of an LED Wall. This function occasionally returned the wrong color value when threading (each thread handles a different i). I reimplemented it using bit shifting and it worked fine. \n","author":{"url":"https://github.com/mattlathrop","@type":"Person","name":"mattlathrop"},"datePublished":"2015-02-02T00:45:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/3077/processing/issues/3077"}
