1、重绘定位点

                    if (matrix[j][i])
                    {
                        ChangeFillShape(g, Forebrush, rect, EN_FillShape.FillRectangle, new FillShape(), Forebrush);

                        //重绘定位框
                        ChangeFixedShape(EN_FixedShape.Fixed1, g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush, j, i);
                        ChangeFixedShape(EN_FixedShape.Fixed2, g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush, j, i);
                        ChangeFixedShape(EN_FixedShape.Fixed3, g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush, j, i);
                    }
                    else
                    {
                        ChangeFillShape(g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush);
                    }

2、修改定位点

            for (int i = 0; i < matrix.Length; i++)
            {
                for (int j = 0; j < matrix.Length; j++)
                {
                    rect = new Rectangle((j + this.SpacingW) * QrCodeEncoder.QRCodeScale, (i + this.SpacingH) * QrCodeEncoder.QRCodeScale, QrCodeEncoder.QRCodeScale, QrCodeEncoder.QRCodeScale);
                    if (matrix[j][i])
                    {
                        ChangeFillShape(g, Forebrush, rect, EN_FillShape.FillRectangle, new FillShape(), Forebrush);

                        //重绘定位框
                        ChangeFixedShape(EN_FixedShape.Fixed1, g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush, j, i);
                        ChangeFixedShape(EN_FixedShape.Fixed2, g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush, j, i);
                        ChangeFixedShape(EN_FixedShape.Fixed3, g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush, j, i);
                    }
                    else
                    {
                        ChangeFillShape(g, Backbrush, rect, EN_FillShape.FillRectangle, new FillShape(), Backbrush);
                    }
                }
            }
            this.ChangeFixedShape(Backbrush, Forebrush, g, EN_FillShape.FillPeach, EN_FillShape.FillPeach, new FillShape(), new FillShape(), true);
            return image;

this.ChangeFixedShape(Backbrush, new SolidBrush(Color.Red), g, EN_FillShape.FillHeart, EN_FillShape.FillPeach, new FillShape(), new FillShape(), true);

this.ChangeFixedShape(Backbrush, new SolidBrush(Color.Red), g, EN_FillShape.FillPeach, EN_FillShape.FillHeart, new FillShape(), new FillShape(), true);

this.ChangeFixedShape(Backbrush, new SolidBrush(Color.Red), g, EN_FillShape.FillHeart, EN_FillShape.FillHeart, new FillShape(), new FillShape(), true);

this.ChangeFixedShape(Backbrush, new SolidBrush(Color.Blue), g, EN_FillShape.FillPolygon, EN_FillShape.FillDiamond, new FillShape() { pointed=5}, new FillShape(), true);
