这篇文章主要介绍了将文本文件的内容或者文字保存成图片的方法,需要的朋友可以参考下

调用方法： 代码如下: ConvertTextFileToImage(Server.MapPath("~/Log.txt"),Server.MapPath("~/Log.png"));     实现代码：  代码如下: void ConvertTextFileToImage(String textFile,String imageFile) { System.Drawing.Font drawFont = new System.Drawing.Font("宋体", 12); System.Drawing.Bitmap image = new System.Drawing.Bitmap(1, 1); System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(image); String text = System.IO.File.ReadAllText(textFile, Encoding.GetEncoding("GB2312")); System.Drawing.SizeF sf = g.MeasureString(text, drawFont, 1024); //设置一个显示的宽度  image = new System.Drawing.Bitmap(image, new System.Drawing.Size(Convert.ToInt32(sf.Width), Convert.ToInt32(sf.Height))); g = System.Drawing.Graphics.FromImage(image); g.Clear(System.Drawing.Color.White); g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit; g.DrawString(text, drawFont, System.Drawing.Brushes.Black, new System.Drawing.RectangleF(new System.Drawing.PointF(0, 0), sf)); image.Save(imageFile, System.Drawing.Imaging.ImageFormat.Png); g.Dispose(); image.Dispose(); }
