Examples

This example shows how to create a TIFF image from scratch and save it to a file.

[C#]

string dir = "c:\\temp\\";

Aspose.Imaging.ImageOptions.TiffOptions createOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
    
// Set 8 bits for each color component.

// Create a TIFF Frame of 100x100 px.
// Note that you don't have to dispose a frame explicitly if it is included into TiffImage.
// When the container is disposed all frames will be disposed automatically.
Aspose.Imaging.FileFormats.Tiff.TiffFrame firstFrame = new Aspose.Imaging.FileFormats.Tiff.TiffFrame(createOptions, 100, 100);
    
// Fill the entire frame with the blue-yellow gradient.
Aspose.Imaging.Brushes.LinearGradientBrush gradientBrush = new Aspose.Imaging.Brushes.LinearGradientBrush(
        new Aspose.Imaging.Point(0, 0),
        new Aspose.Imaging.Point(firstFrame.Width, firstFrame.Height),
        Aspose.Imaging.Color.Blue,
        Aspose.Imaging.Color.Yellow);

Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(firstFrame);
graphics.FillRectangle(gradientBrush, firstFrame.Bounds);

// Create a TIFF image.
using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = new Aspose.Imaging.FileFormats.Tiff.TiffImage(firstFrame))
{
    tiffImage.Save(dir + "output.tif");
}

This example shows how to save a raster image to the TIFF format using various options.

[C#]

string dir = "c:\\temp\\";

// Set the Big Endian byte order (Motorola)

// Set the LZW compression.
saveOptions.Compression = Aspose.Imaging.FileFormats.Tiff.Enums.TiffCompressions.Lzw;

// Allow to reduce the size of continuous-tone images.
// Currently this field is used only with LZW encoding because LZW is probably the only TIFF encoding scheme
// that benefits significantly from a predictor step.
saveOptions.Predictor = Imaging.FileFormats.Tiff.Enums.TiffPredictor.Horizontal;

// Set the RGB color model.
saveOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;

// For YCbCr, you can use one of the following choices:
// YCbCrSubSampling field   JPEG sampling factors
// ----------------------------------------------
// 1,1                      1x1, 1x1, 1x1
// 2,1                      2x1, 1x1, 1x1
// 2,2(default value)       2x2, 1x1, 1x1
// saveOptions.YCbCrSubsampling = new ushort[] { 2, 2 };

// All color components will be stored within a singel plane.
saveOptions.PlanarConfiguration = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPlanarConfigs.Contiguous;

// Create a TIFF Frame of 100x100 px.
using (Aspose.Imaging.Image image = new Aspose.Imaging.FileFormats.Bmp.BmpImage(100, 100))
{
    // Fill the entire image with the blue-yellow gradient.
    Aspose.Imaging.Brushes.LinearGradientBrush gradientBrush = new Aspose.Imaging.Brushes.LinearGradientBrush(
            new Aspose.Imaging.Point(0, 0),
            new Aspose.Imaging.Point(image.Width, image.Height),
            Aspose.Imaging.Color.Blue,
            Aspose.Imaging.Color.Yellow);

    Aspose.Imaging.Graphics graphics = new Aspose.Imaging.Graphics(image);
    graphics.FillRectangle(gradientBrush, image.Bounds);

    image.Save(dir + "output.tif", saveOptions);
}

This example shows how to create a TIFF image with 2 frames and save it to a file.

createOptions2.BitsPerSample = new ushort[] { 1 };

// Set the Little Endian byte order (Intel)
createOptions2.ByteOrder = Aspose.Imaging.FileFormats.Tiff.Enums.TiffByteOrder.LittleEndian;

// Set the CCITT Group 3 Fax compression.

// It will be automatically converted to the B/W format due to the corresponding settings of the frame.
Aspose.Imaging.Graphics graphics2 = new Aspose.Imaging.Graphics(frame2);
graphics2.FillRectangle(gradientBrush, frame2.Bounds);

// Create a TIFF image.
using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = new Aspose.Imaging.FileFormats.Tiff.TiffImage(
