java - Cutting shapes from image -

i have buffered image, , array of shapes puzzle pieces. want cut shapes image. tried clipping image doesn't work properly. i've done far is:

    (int = 0; < rows; i++) {         (int j = 0; j < cols; j++) {             area area = areas[i][j];             int width = (int) area.getbounds2d().getwidth();             int height = (int) area.getbounds2d().getheight();              pieces[i][j] = new bufferedimage(width, height, image.gettype());             graphics2d gr = pieces[i][j].creategraphics();             gr.setclip(area);             gr.drawimage(image, 0, 0, null);             gr.dispose();              try {                 imageio.write(pieces[i][j], "png", new file("img/img" + + "" + j + ".png"));             } catch (ioexception e) {                 e.printstacktrace();             }         }     } 

it works first shape, writes transparent images output.

actually there plenty of methods this. here approach :)

int width = 0; int height = 0; int rows = 0; int columns = 0; bufferedimage sheet = // image goes here  bufferedimage[] pieces = new bufferedimage[rows * cols]; (int = 0; < rows; i++) {     (int j = 0; j < cols; j++) {         pieces[(i * cols) + j] = sheet.getsubimage(j * width, * height, width, height);         } } 

note pieces in 1 array. if still want pieces in two-dimensional array:

// switch these lines bufferedimage[][] pieces = new bufferedimage[rows][cols]; pieces[i][j] = sheet.getsubimage(j * width, * height, width, height);
