JpegImage.ExifData

JpegImage.ExifData property

使用此属性管理 EXIF 数据，允许您添加或检索与图像关联的元数据。无论是提取相机设置信息还是修改现有元数据，此属性都提供了管理 EXIF 数据容器的灵活性。

public JpegExifData ExifData { get; set; }

示例

以下示例展示了如何从 JPEG 图像中提取 EXIF 标签。

[C#]

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

using (Aspose.Imaging.FileFormats.Jpeg.JpegImage image = (Aspose.Imaging.FileFormats.Jpeg.JpegImage)Image.Load(dir + "original.jpg"))
{
    Aspose.Imaging.Exif.ExifData exifData = image.ExifData;

    System.Console.WriteLine("The general EXIF data");
    System.Console.WriteLine("------------------------------------------");
    if (exifData != null)
    {
        System.Console.WriteLine("The EXIF version: {0}", exifData.ExifVersion);
        System.Console.WriteLine("The camera serial number: {0}", exifData.BodySerialNumber);
        System.Console.WriteLine("The color space: {0}", exifData.ColorSpace);
        System.Console.WriteLine("The brightness: {0}", exifData.BrightnessValue);
        System.Console.WriteLine("The contrast: {0}", exifData.Contrast);
        System.Console.WriteLine("The gamma: {0}", exifData.Gamma);
        System.Console.WriteLine("The sharpness: {0}", exifData.Sharpness);
        System.Console.WriteLine("The aperture: {0}", exifData.ApertureValue);
        System.Console.WriteLine("The exposure mode: {0}", exifData.ExposureMode);
        System.Console.WriteLine("The exposure bias: {0}", exifData.ExposureBiasValue);
        System.Console.WriteLine("The exposure time: {0}", exifData.ExposureTime);
        System.Console.WriteLine("The focal length: {0}", exifData.FocalLength);
        System.Console.WriteLine("The focal plane resolution unit: {0}", exifData.FocalPlaneResolutionUnit);
        System.Console.WriteLine("The lens model: {0}", exifData.LensModel);
        System.Console.WriteLine("The shutter speed: {0}", exifData.ShutterSpeedValue);
    }

    System.Console.WriteLine("The JPEG EXIF data");
    System.Console.WriteLine("------------------------------------------");
    Aspose.Imaging.Exif.JpegExifData jpegExifData = image.ExifData as Aspose.Imaging.Exif.JpegExifData;
    if (jpegExifData != null)
    {
        System.Console.WriteLine("The camera manufacturer: {0}", jpegExifData.Make);
        System.Console.WriteLine("The camera model: {0}", jpegExifData.Model);
        System.Console.WriteLine("The photometric interpretation: {0}", jpegExifData.PhotometricInterpretation);
        System.Console.WriteLine("The artist: {0}", jpegExifData.Artist);
        System.Console.WriteLine("The copyright: {0}", jpegExifData.Copyright);
        System.Console.WriteLine("The image description: {0}", jpegExifData.ImageDescription);
        System.Console.WriteLine("The orientation: {0}", jpegExifData.Orientation);
        System.Console.WriteLine("The software: {0}", jpegExifData.Software);
    }
}

//输出如下：
