Examples
Questo esempio crea una nuova Immagine e attira una varietà di forme utilizzando Figure e GraphicsPath sulla superficie dell’Imagine
//Creates an instance of BmpOptions and set its various properties
Aspose.Imaging.ImageOptions.BmpOptions bmpOptions = new Aspose.Imaging.ImageOptions.BmpOptions();
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
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Create(bmpOptions, 500, 500))
{
//Create and initialize an instance of Graphics class
