Examples
Detta exempel skapar en ny bild och drar en mängd olika former med hjälp av Figurer och GraphicsPath på bildytan.
//Creates an instance of BmpOptions and set its various properties

bmpOptions.BitsPerPixel = 24;
//Create an instance of FileCreateSource and assign it as Source for the instance of BmpOptions
//Second Boolean parameter determines if the file to be created IsTemporal or not
bmpOptions.Source = new Aspose.Imaging.Sources.FileCreateSource(@"c:\temp\output.bmp", false);
//Create an instance of Image
