Media_Map_Transparency
(remixed from Scratch-Conference_Pixels, by youngthinkers)It finds pixels with specific RGB values and it changes their transparency (the 'A' value in RGBA) to 20. See the forum discussion https://forum.snap.berkeley.edu/t/957 that led to redesigned SWITCH TO block. It now accepts list of pixels, too. Yay!!! :-)
