I want to draw a circle, then internal subdivision, then each small area for color fill (want to take advantage of matrix corresponding to each small area, through the RGB color fill), excuse me this how to implement? Thank you very much!

CodePudding user response:

Use QImage, direct manipulation of pixel color to fill the QImage has a member method, like call setPixel (int x, int y, QColor color)
