ResizeHeightProportionally

TiffImage.ResizeHeightProportionally method

按比例调整宽度。

public override void ResizeHeightProportionally(int newHeight, ResizeType resizeType)

范围	类型	描述
newHeight	Int32	新高度。
resizeType	ResizeType	调整大小的类型。

例子

此示例加载 TIFF 图像并使用各种调整大小方法按比例调整其大小。仅指定高度，自动计算宽度。

[C#]

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

using (Aspose.Imaging.FileFormats.Tiff.TiffImage image = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
    // 使用最近邻重采样放大 2 倍。
    image.ResizeHeightProportionally(image.Height* 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);

    // 使用默认选项保存到 PNG。
    image.Save(dir + "upsample.nearestneighbour.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.Tiff.TiffImage image = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
    // 使用最近邻重采样缩小 2 倍。
    image.ResizeHeightProportionally(image.Height / 2, Aspose.Imaging.ResizeType.NearestNeighbourResample);

    // 使用默认选项保存到 PNG。
    image.Save(dir + "downsample.nearestneighbour.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.Tiff.TiffImage image = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
    // 使用双线性重采样放大 2 倍。
    image.ResizeHeightProportionally(image.Height* 2, Aspose.Imaging.ResizeType.BilinearResample);

    // 使用默认选项保存到 PNG。
    image.Save(dir + "upsample.bilinear.png", new Aspose.Imaging.ImageOptions.PngOptions());
}

using (Aspose.Imaging.FileFormats.Tiff.TiffImage image = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
    // 使用双线性重采样缩小 2 倍。
    image.ResizeHeightProportionally(image.Height / 2, Aspose.Imaging.ResizeType.BilinearResample);

    // 使用默认选项保存到 PNG。
    image.Save(dir + "downsample.bilinear.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
