fileName = "blocks_and_tables_\-_imperial_.dxf"; using (CadImage cadImage = (CadImage)Image.Load(fileName)) { Console.WriteLine(fileName); PdfOptions pdfOptions = new PdfOptions(); pdfOptions.VectorRasterizationOptions = (new CadRasterizationOptions()); CadRasterizationOptions cadRasterizationOptions = (CadRasterizationOptions)pdfOptions.VectorRasterizationOptions; cadRasterizationOptions.BackgroundColor = (Color.White); cadRasterizationOptions.DrawColor = (Color.Black); cadRasterizationOptions.DrawType = (CadDrawTypeMode.UseDrawColor); cadRasterizationOptions.ScaleMethod = (ScaleType.ShrinkToFit); cadRasterizationOptions.PageWidth = (1000); cadRasterizationOptions.PageHeight = (800); cadRasterizationOptions.AutomaticLayoutsScaling = true; cadImage.Save(outPath, pdfOptions); }
IMAGING-33189 Converting images to PNG 1 bpp
New property BitDepth in PngOptions. Right now bitdepth of 1, 2, 4 and 8 bits are available for grayscale and indexed color types. For other color types only 8 bits bitdepth is available. using (PngImage png = (PngImage)Image.Load(inputPath)) { PngOptions options = new PngOptions(); options.ColorType = PngColorType.Grayscale; options.BitDepth = 1; png.Save(outputpath, options); }
