C#操作EXCEL以及生成公司公章

最近项目需求 做了个小工具 操作EXCEL以及生成公司公章 

TestOnSeal _top = new TestOnSeal();
            _top.TextFont = new System.Drawing.Font("黑体", 16, FontStyle.Bold);
            _top.FillColor = Color.Red;
            //_top.ColorTOP = Color.Black;
            _top.Text = comname;
            _top.BaseString = "";
            _top.ShowPath = true;
            _top.LetterSpace = 1;
            _top.SealSize = 180;
            _top.CharDirection = Char_Direction.Center;
            _top.SetIndent(20);
            Graphics g = this.CreateGraphics();
            g.DrawImage(_top.TextOnPathBitmap(), 0, 0);

            _top.CharDirection = Char_Direction.ClockWise;
            g.DrawImage(_top.TextOnPathBitmap(), 180, 0);

            _top.CharDirection = Char_Direction.AntiClockWise;
            g.DrawImage(_top.TextOnPathBitmap(), 0, 180);

            _top.SetIndent(20);
            _top.CharDirection = Char_Direction.Center;
            g.DrawImage(_top.TextOnPathBitmap(), 180, 180);

            _top.TextOnPathBitmap().Save(System.Windows.Forms.Application.StartupPath + "/tp/" + comname + ".png",  System.Drawing.Imaging.ImageFormat.Png);

            g.Dispose();

C# GDI画图 两张图片合并

好久没发文章了,整点东西上来,废话就不多说了,代码如下：

Bitmap bmp1 = new Bitmap(Application.StartupPath + "\\1.png");
            Bitmap bmp2 = new Bitmap(Application.StartupPath + "\\1.jpg");
            using (Graphics g = Graphics.FromImage(bmp1))
            {
                Size size = new Size(265, 265);
                Rectangle rect = new Rectangle(new Point(bmp1.Width - size.Width - 118, 96), size);
                g.DrawImage(bmp2, rect, new Rectangle(0, 0, bmp2.Width, bmp2.Height), GraphicsUnit.Pixel);
                bmp1.Save(Application.StartupPath + "\\C.jpg");
            }
