Examples
下面的示例显示如何创建现有框架的图像,并将其添加到 TIFF 图像中。
string dir = "c:\\temp\\";
Aspose.Imaging.ImageOptions.TiffOptions createTiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
// Create a permanent, not temporary file source.
createTiffOptions.Source = new Aspose.Imaging.Sources.FileCreateSource(dir + "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))
{
// The linear gradient from the left-top to the right-bottom corner of the image.
Aspose.Imaging.Brushes.LinearGradientBrush brush =
new Aspose.Imaging.Brushes.LinearGradientBrush(
new Aspose.Imaging.Point(0, 0),
new Aspose.Imaging.Point(tiffImage.Width, tiffImage.Height),
Aspose.Imaging.Color.Red,
Aspose.Imaging.Color.Green);
// Fill the active frame with a linear gradient brush.
Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(tiffImage.ActiveFrame);
gr.FillRectangle(brush, tiffImage.Bounds);
// Grayscale options
Aspose.Imaging.ImageOptions.TiffOptions createTiffFrameOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
createTiffFrameOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());
createTiffFrameOptions.Photometric = Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.MinIsBlack;
createTiffFrameOptions.BitsPerSample = new ushort[] { 8 };
// Create a grayscale copy of the active frame.
// The pixel data is preserved but converted to the desired format.
Aspose.Imaging.FileFormats.Tiff.TiffFrame grayscaleFrame = Aspose.Imaging.FileFormats.Tiff.TiffFrame.CreateFrameFrom(tiffImage.ActiveFrame, createTiffFrameOptions);
// Add the newly created frame to the TIFF image.
tiffImage.AddFrame(grayscaleFrame);
tiffImage.Save();
}LinearGradientBrush()
