Full comments and a java language implementation are needed. Write some code so that your name is shown in red font inside a blue frame, then save the file.
Use python code with "def drawItem(img,item,row,col):" but without using cv2,PIL or numpy drawItem(canvas, item, row, col) - Modify canvas by drawing the non-white pixels of the item (intended to be the image of a word) onto canvas. Row and col represent the top left pixel of canvas where the item (the item's top left 0,0 pixel) should be placed. Canvas and item are 2D images of RGB pixels. This function should assume that the canvas image is large enough to contain the item img in the row col indicated; row and col do NOT need to be validated.
