Canvas and Paths seem to be something very powerfull, once you understand how it works... There are some free image to svg path converters that take any image file and return a SVG Data formated path. This would be very usefull if we could use such format for complex form paths. Someting like B4XPath.InitializePathData(M140 20C73 20 20 74 20 140c0 135 136 170 228 303 88-132 229-173 229-303 0-66-54-120-120-120-48 0-90 28-109 69-19-41-60-69-108-69z) This path results in a heart shape...

Is it possible to read and modify the points inserted in a Path? For the moment I am inserting the points also in a list and every modification I make it on the list that I re-enter in the B4Xpath after having reset it. Is there another way?...
