CreateFrameFrom

TiffFrame.CreateFrameFrom method

Creates the frame from specified tiffFrame using the specified options. The pixel data is preserved but converted to the desired format.

public static TiffFrame CreateFrameFrom(TiffFrame tiffFrame, TiffOptions options)
Parameter Type Description
tiffFrame TiffFrame The tiff frame to create from.
options TiffOptions The new options to use.

Return Value

The newly created frame.

Examples

The following example shows how to create a grayscale copy of an existing frame and add it to a TIFF image.

[C#]

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();
}
