drawImage method

@override void drawImage(PCanvasImage image, num x, num y)

Draw an image at (x,y) using the original dimension of the image.

Implementation

@override
void drawImage(PCanvasImage image, num x, num y) {
  checkImageLoaded(image);

  x = transform.x(x);
  y = transform.y(y);

  var clip = _clip;

    var imgW = image.width;
    var imgH = image.height;

    var box = PRectangle(x, y, imgW, imgH);
    var r = clip.intersection(box);
    if (r.isZeroDimension) return;

    if (r.width != imgW || r.height != imgH) {
      drawImageArea(image, 0, 0, imgW, imgH, x, y, imgW, imgH);
      return;
    }
  }

  if (image is PCanvasImageMemory) {
    var srcImg = image.image;
