使用示例
// 读取图片using (var image = new MagickImage("c:\path\to\Snakeware.jpg")){}using (var image = new MagickImage()){ image.Read("c:\path\to\Snakeware.jpg"); image.Read(memStream); image.Read("xc:yellow", settings);using (var memStream = LoadMemoryStreamImage()) { image.Read(memStream); }}
//gif图片大小改变using (var collection = new MagickImageCollection("c:\path\to\SnakewareGif")){ collection.Coalesce(); foreach (var image in collection) { image.Resize(200, 0); } collection.Write("c:\path\to\Snakeware.resized.gif");}// png图片大小改变using (var image = new MagickImage("c:\path\to\SnakewarePng")){ var size = new MagickGeometry(100, 100); size.IgnoreAspectRatio = true; image.Resize(size); image.Write("c:\path\to\Snakeware.100x100.png");}// gif 转 pngusing (var image = new MagickImage("c:\path\to\Snakeware.gif")){ // Save frame as jpg image.Write("c:\path\to\Snakeware.jpg");}// 转为png格式var settings = new MagickReadSettings();settings.Width = 800;settings.Height = 600;using (var memStream = new MemoryStream()){ using (var image = new MagickImage("xc:purple", settings)) { image.Format = MagickFormat.Png; image.Write(memStream); }}// png 转 jpegusing (var image = new MagickImage("c:\path\to\Snakeware.png")){ image.Format = MagickFormat.Jpeg; byte[] data = image.ToByteArray();}//pdf 转化为 png、tif格式var settings = new MagickReadSettings();settings.Density = new Density(300, 300);using (var images = new MagickImageCollection()){ images.Read("c:\path\to\Snakeware.pdf", settings);var page = 1; foreach (var image in images) { image.Write("c:\path\to\Snakeware.Page" + page + ".png"); image.Format = MagickFormat.Ptif; image.Write("c:\path\to\Snakeware.Page" + page + ".tif"); page++; }}// 图片转为pdfusing (var image = new MagickImage("c:\path\to\Snakeware.jpg")){ // Create pdf file with a single page image.Write("c:\path\to\Snakeware.pdf");}//读取指定pdfusing (var images = new MagickImageCollection()){ var settings = new MagickReadSettings(); settings.FrameIndex = 0; settings.FrameCount = 1; images.Read("c:\path\to\Snakeware.pdf", settings); images.Clear(); settings.FrameCount = 2; images.Read("c:\path\to\Snakeware.pdf", settings);}//添加水印using (var image = new MagickImage("c:\path\to\Snakeware.jpg")){ using (var watermark = new MagickImage("c:\path\to\Magick.NET.png")) { image.Composite(watermark, Gravity.Southeast, CompositeOperator.Over); watermark.Evaluate(Channels.Alpha, EvaluateOperator.Divide, 4); image.Composite(watermark, 200, 50, CompositeOperator.Over); } image.Write("c:\path\to\Snakeware.watermark.jpg");}//添加文字using (var image = new MagickImage(new MagickColor("#ff00ff"), 512, 128)){ new Drawables() .FontPointSize(72) .Font("Comic Sans") .StrokeColor(new MagickColor("yellow")) .FillColor(MagickColors.Orange) .TextAlignment(TextAlignment.Center) .Text(256, 64, "Magick.NET") .StrokeColor(new MagickColor(0, Quantum.Max, 0)) .FillColor(MagickColors.SaddleBrown) .Ellipse(256, 96, 192, 8, 0, 360) .Draw(image);}
using (var images = new MagickImageCollection()){ var first = new MagickImage("c:\path\to\Snakeware.png"); images.Add(first); var second = new MagickImage("c:\path\to\Snakeware.png"); images.Add(second); using(var result = images.Mosaic()) { result.Write("Mosaic.png"); }}https://github.com/dlemstra/Magick.NET
