Aspose.Imaging for .NET一种高级图像处理控件,允许开发人员创建,编辑,绘制或转换图像。图像导出和转换是API核心功能之一,它允许在不安装Photoshop应用程序或任何其他图像编辑器的情况下保存为AdobePhotoshop®本机格式。
近期发布了Aspose.Imaging for .NET v19.7,支持PartialRotater类中的优化策略,支持OTG(OpenDocument图形模板),下面我们一起来探索新版中的新增功能及其工作原理。>>欢迎下载Aspose.Imaging for .NET v19.7体验
//将文本转换为向量对象 using (Image image = Image.Load("text.psd")) { image.Save(fileName + "text_vector.pdf", new PdfOptions()); }// //老式的转换与充分光栅化 using (Image image = Image.Load("text.psd", new PsdLoadOptions() { ReadOnlyMode = true })) { image.Save(fileName + "text_vector.pdf", new PdfOptions()); }
//为目标加载的图像设置50兆字节的内存限制 using (var image = Image.Load(imageFilePath, new LoadOptions() { BufferSizeHint = 50 })) { //执行RotateFlip操作 image.RotateFlip(RotateFlipType.Rotate90FlipNone); //执行旋转操作 ((RasterImage)image).Rotate(60); // rotate 60 degrees clockwise }
string baseFolder = "D:"; string fileName = "VariousObjectsMultiPage.otg"; ImageOptionsBase[] options = { new PngOptions(), new PdfOptions() }; foreach (ImageOptionsBase item in options) { string inputFileName = Path.Combine(baseFolder, fileName); string fileExt = item is PngOptions ? ".png" : ".pdf"; string outputFileName = Path.Combine(baseFolder, fileName + fileExt); using (Image image = Image.Load(inputFileName)) { OtgRasterizationOptions otgRasterizationOptions = new OtgRasterizationOptions(); otgRasterizationOptions.PageSize = image.Size; item.VectorRasterizationOptions = otgRasterizationOptions; image.Save(outputFileName, item); } }
using(Image image = Image.Load(“input.svg”)) { image.Save( “output.png”, new PngOptions() { VectorRasterizationOptions = new SvgRasterizationOptions { PageSize = image.Size, } }); }
string baseFolder =“D: ”; string fileName =“standardSize.tif”; string inputFileName = Path.Combine(baseFolder,fileName); string outFileName = inputFileName +“。pdf”; using(Image image = Image.Load(inputFileName)) { PdfOptions pdfOptions = new PdfOptions {PageSize = new SizeF(612,792 )}; image.Save(outFileName,pdfOptions); }
string baseFolder = Path.Combine("D:","3286"); string fileName = "image2.wmf"; string inputFileName = Path.Combine(baseFolder, fileName); using (Image image = Image.Load(inputFileName)) { string script = ((WmfImage)image).GetPostScript(); string ethlonScript = File.ReadAllText(inputFileName + ".ps"); if (script != ethlonScript) { throw new Exception("script not eqal ethalon script"); } } Since PostScript is not supported in Aspose products, further processing is done by **third-party applications**. For example: Use ghostscript (//ghostscript.com/) string baseFolder = Path.Combine("D:","3286"); string fileName = "image2.wmf"; string inputFileName = Path.Combine(baseFolder, fileName); string scriptFileName = inputFileName + ".ps"; string outputPdfFileName = scriptFileName + ".pdf"; string ghostPath = "C: Program Files (x86) gs gs8.61 bin gswin32c.exe"; string script; using (Image image = Image.Load(inputFileName)) { script = ((WmfImage)image).GetPostScript(); } File.WriteAllText(scriptFileName, script); string cmdArguments = string.Format(" -sDEVICE=pdfwrite -o {0} {1}", outputPdfFileName, scriptFileName); Process proc = System.Diagnostics.Process.Start(ghostPath, cmdArguments); proc.WaitForExit(60000);
using(Image image = Image.Load(“input.jpg”)) { image.Save(“output.tiff”,new TiffOptions(TiffExpectedFormat.TiffJpegRgb)); }
string baseFolder = Path.Combine("D:", "test"); string fontsFolder = Path.Combine(baseFolder, "fonts"); //创建字体文件夹 if (!Directory.Exists(fontsFolder)) { Directory.CreateDirectory(fontsFolder); }// //复制字体到字体文件夹 string fontFile = Path.Combine(fontsFolder, "foo.ttf"); if (!File.Exists(fontFile)) { File.Copy(Path.Combine(baseFolder, "foo.ttf"), fontFile); }// //设置字体路径 List fonts = new List(FontSettings.GetDefaultFontsFolders()); fonts.Add(fontsFolder); FontSettings.SetFontsFolders(fonts.ToArray(), true);// //打开图片 string inputFile = Path.Combine(baseFolder, "grinched-regular-font.psd"); string outputFile = inputFile + ".png"; using (Image image = Image.Load(inputFile)) { PngOptions saveOptions = new PngOptions(); image.Save(outputFile, saveOptions); } //删除字体文件夹 Directory.Delete(fontsFolder,true);
string baseFolder = "D: "; string inputFileName = Path.Combine(baseFolder, "logotype.svg"); float scale = 10f; using (Image image = Image.Load(inputFileName)) { image.Save(inputFileName+".png", new PngOptions() { VectorRasterizationOptions = new SvgRasterizationOptions() {PageSize = image.Size, ScaleX = scale, ScaleY = scale} }); }
