L’exemple ci-dessous montre comment composer un mutlipage TIFF à partir d’images de raster individuels.
Aspose.Imaging.ImageOptions.TiffOptions createTiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
createTiffOptions.Source = new Aspose.Imaging.Sources.FileCreateSource("c:\\temp\\multipage.tif", false);
createTiffOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;
createTiffOptions.BitsPerSample = new ushort[] { 8, 8, 8 };
using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Image.Create(createTiffOptions, 100, 100))
{
// This is Font and Brush for drawing text on individual frames.
Aspose.Imaging.Font font = new Aspose.Imaging.Font("Arial", 64);
Aspose.Imaging.Brushes.SolidBrush brush = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.White);
// Create 5 frames
for (int i = 1; i <= 5; i++)
{
Aspose.Imaging.ImageOptions.PngOptions createPngOptions = new Aspose.Imaging.ImageOptions.PngOptions();
createPngOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());
// Create a PNG image and draw the number of page on it.
Aspose.Imaging.FileFormats.Png.PngImage pngImage = (Aspose.Imaging.FileFormats.Png.PngImage)Image.Create(createPngOptions, 100, 100);
Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(pngImage);
gr.DrawString(i.ToString(), font, brush, 10, 10);
// Create a frame based on the PNG image.
Aspose.Imaging.FileFormats.Tiff.TiffFrame frame = new Aspose.Imaging.FileFormats.Tiff.TiffFrame(pngImage);
// Add the frame to the TIFF image.
tiffImage.AddFrame(frame);
}
// The image was created with a single default frame. Let's remove it.
Aspose.Imaging.FileFormats.Tiff.TiffFrame activeFrame = tiffImage.ActiveFrame;
tiffImage.ActiveFrame = tiffImage.Frames[1];
tiffImage.RemoveFrame(0);
// Don't forget to dispose the frame if you won't add it to some other TiffImage
activeFrame.Dispose();
tiffImage.Save();
