前言：
此刻看官们对“html 转 word csharp”都比较珍视，同学们都想要知道一些“html 转 word csharp”的相关内容。那么小编也在网摘上网罗了一些对于“html 转 word csharp””的相关内容，希望各位老铁们能喜欢，兄弟们一起来学习一下吧！这个东西我已经用了有段时间了，从开始写文章就在用这个，主要原因还是因为我比较懒。懒得去寻找图片，同时又怕万一惹来版权争议。。。
跟我所有的文章的封面图一样，一个纯色背景加上文字自动生成一个指定大小的图片。
代码实现也比较简单，如果有兴趣的话，可以自己扩展，比如自定义背景图，自定义水印等。
实现功能：
利用C#做一个简单的封面图片生成器
开发环境：
开发工具： Visual Studio 2013
.NET Framework版本：4.5
实现代码：
private void Img_Load(object sender, EventArgs e) { init(); } private void btnBg_Click(object sender, EventArgs e) { ColorDialog cd = new ColorDialog(); if (cd.ShowDialog() == DialogResult.OK) { panelBgColor.BackColor = cd.Color; } } private void btnFontColor1_Click(object sender, EventArgs e) { ColorDialog cd = new ColorDialog(); if (cd.ShowDialog() == DialogResult.OK) { panelFontColor1.BackColor = cd.Color; } } private void btnFontColor2_Click(object sender, EventArgs e) { ColorDialog cd = new ColorDialog(); if (cd.ShowDialog() == DialogResult.OK) { panelFontColor2.BackColor = cd.Color; } } private void btnFont_Click(object sender, EventArgs e) { FontDialog fd = new FontDialog(); fd.Font = txtFont.Font; if (fd.ShowDialog() == DialogResult.OK) { txtFont.Font = fd.Font; } } private void btnPre_Click(object sender, EventArgs e) { if (string.IsNullOrWhiteSpace(txtWord.Text)) { MessageBox.Show("请先设置文字", "提示"); return; } MemoryStream stream = new MemoryStream(CreateIamge(txtWord.Text)); pictureBox1.Image = Image.FromStream(stream, true); } private void btnSave_Click(object sender, EventArgs e) { if (pictureBox1.Image == null) { MessageBox.Show("请先预览", "提示"); return; } SaveFileDialog sfd = new SaveFileDialog(); sfd.SupportMultiDottedExtensions = true; sfd.Filter = "PNG格式|*.png|JPG格式|*.jpg"; sfd.AddExtension = true; if (sfd.ShowDialog() == DialogResult.OK) { EncoderParameters myEncoderParameters = new EncoderParameters(1); myEncoderParameters.Param[0] = new EncoderParameter(Encoder.Quality, 100L); pictureBox1.Image.Save(sfd.FileName, GetEncoderInfo("image/png"), myEncoderParameters); } } private void init() { Font font = new Font("华文行楷", 36, FontStyle.Bold); txtFont.Font = font; panelFontColor1.BackColor = ColorTranslator.FromHtml("#ff0080ff"); panelFontColor2.BackColor = ColorTranslator.FromHtml("#ffff80c0"); } public byte[] CreateIamge(string str) { int w = Convert.ToInt32(txtWidth.Text); int h = Convert.ToInt32(txtHeight.Text); //渐变画笔 LinearGradientBrush brush = new LinearGradientBrush(new Rectangle(0, 0, w, h), panelFontColor1.BackColor, panelFontColor2.BackColor, 25f, true); Bitmap image = new Bitmap(w, h); Graphics g = Graphics.FromImage(image); //设置高质量插值法 g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; //设置高质量,低速度呈现平滑程度 g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality; g.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality; //消除锯齿 g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias; //填充背景色 g.FillRectangle(new SolidBrush(panelBgColor.BackColor), new Rectangle(0, 0, w, h)); //设置文本呈现方式 g.TextRenderingHint = TextRenderingHint.ClearTypeGridFit; //获取文字大小 SizeF sf = g.MeasureString(str, txtFont.Font); g.DrawString(str, txtFont.Font, brush, (w - sf.Width) / 2, (h - sf.Height) / 2); MemoryStream stream = new MemoryStream(); //高质量保存 EncoderParameters myEncoderParameters = new EncoderParameters(1); myEncoderParameters.Param[0] = new EncoderParameter(Encoder.Quality, 100L); image.Save(stream, GetEncoderInfo("image/png"), myEncoderParameters); byte[] buffer = stream.ToArray(); g.Dispose(); image.Dispose(); return buffer; } private static ImageCodecInfo GetEncoderInfo(String mimeType) { int j; ImageCodecInfo[] encoders; encoders = ImageCodecInfo.GetImageEncoders(); for (j = 0; j < encoders.Length; ++j) { if (encoders[j].MimeType == mimeType) return encoders[j]; } return null; }实现效果：
由简入繁，拿来即用
