DateTimeStamp

TgaImage.DateTimeStamp property

获取或设置日期/时间戳。此字段定义保存图像的日期和时间的值。尽管操作系统通常使用时间戳和日期戳文件，但提供了此功能，因为如果文件被复制，操作系统可能会更改时间和日期戳。通过使用此区域，您可以保证日期和时间的未修改区域 recording.

public DateTime? DateTimeStamp { get; set; }

例子

更新加载的 TGA 映像的公共属性。

[C#]

using (TgaImage image = (TgaImage)Image.Load("test.tga"))
{
    image.DateTimeStamp = testTime;
    image.AuthorName = "John Smith";
    image.AuthorComments = "Comment";
    image.ImageId = "ImageId";
    image.JobNameOrId = "Important Job";
    image.JobTime = TimeSpan.FromDays(10);
    image.TransparentColor = Color.FromArgb(123);
    image.SoftwareId = "SoftwareId";
    image.SoftwareVersion = "abc1";
    image.SoftwareVersionLetter = 'a';
    image.SoftwareVersionNumber = 2;
    image.XOrigin = 1000;
    image.YOrigin = 1000;

    image.Save("test.tga")
}

获取加载的 TGA 图像的公共属性的值。

[C#]

using (TgaImage image = (TgaImage)Image.Load("test.tga"))
{
    dateTimeStamp = image.DateTimeStamp;
    authorName = image.AuthorName;
    authorComments = image.AuthorComments;
    imageId = image.ImageId;
    jobNameOrId = image.JobNameOrId;
    jobTime = image.JobTime;
    keyColor = image.TransparentColor;
    softwareId = image.SoftwareId;
    softwareVersion = image.SoftwareVersion;
    softwareVersionLetter = image.SoftwareVersionLetter;
    softwareVersionNumber = image.SoftwareVersionNumber;
    xOrigin = image.XOrigin;
    yOrigin = image.YOrigin;
    gammaValueDenominator = image.GammaValueDenominator;
    gammaValueNumerator = image.GammaValueNumerator;
    hasAlphaChannel = image.HasAlpha;
    hasColorMap = image.HasColorMap;
    height = image.Height;
    isGrayScale = image.IsGrayScale;
    pixelAspectRatioDenominator = image.PixelAspectRatioDenominator;
    pixelAspectRatioNumerator = image.PixelAspectRatioNumerator;
    size = image.Size;
    width = image.Width;
}
