HasAlpha

TiffImage.HasAlpha property

Determine whether the image has an alpha channel, providing crucial information for rendering and compositing operations. Integrate this feature to optimize visual processing workflows, ensuring accurate representation and manipulation of transparent elements.

public override bool HasAlpha { get; }

Property Value

The Has alpha channel.

Examples

The following example loads a TIFF image and prints information about raw data format and alpha channel.

[C#]

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

string fileName = dir + "sample.tif";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(fileName))
{
    Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)image;

    // If the active TIFF frame has alpha channel, then the entire TIFF image is considered to have alpha channel.
    System.Console.WriteLine("ImageFile={0}, FileFormat={1}, HasAlpha={2}", fileName, tiffImage.RawDataFormat, tiffImage.HasAlpha);

    int i = 0;
    foreach (Aspose.Imaging.FileFormats.Tiff.TiffFrame frame in tiffImage.Frames)
    {
        System.Console.WriteLine("Frame={0}, FileFormat={1}, HasAlpha={2}", ++i, frame.RawDataFormat, frame.HasAlpha);
    }
}

// The output may look like this:
// ImageFile=c:\temp\sample.tif, FileFormat=RgbIndexed1Bpp, used channels: 1, HasAlpha=False
// Frame=1, FileFormat=RgbIndexed1Bpp, used channels: 1, HasAlpha=False
// Frame=2, FileFormat=RgbIndexed1Bpp, used channels: 1, HasAlpha=False
