WatermarkerContext.ImageWatermark property

用作水印的图像字节。

public byte[] ImageWatermark { get; set; }

评论

如果两者ImageWatermark和TextWatermark指定后，文本水印将覆盖图像水印。

例子

显示如何使用上下文将水印图像插入到文档中。

string doc = MyDir + "Document.docx";
string watermarkImage = ImageDir + "Logo.jpg";

WatermarkerContext watermarkerContext = new WatermarkerContext();
watermarkerContext.ImageWatermark = File.ReadAllBytes(watermarkImage);

watermarkerContext.ImageWatermarkOptions.Scale = 50;

Watermarker.Create(watermarkerContext)
    .From(doc)
    .To(ArtifactsDir + "LowCode.WatermarkContextImage.docx")
    .Execute();

展示如何使用上下文从流中将水印图像插入到文档中。

string watermarkImage = ImageDir + "Logo.jpg";

using (FileStream streamIn = new FileStream(MyDir + "Document.docx", FileMode.Open, FileAccess.Read))
{
    WatermarkerContext watermarkerContext = new WatermarkerContext();
    watermarkerContext.ImageWatermark = File.ReadAllBytes(watermarkImage);

    watermarkerContext.ImageWatermarkOptions.Scale = 50;

    using (FileStream streamOut = new FileStream(ArtifactsDir + "LowCode.WatermarkContextImageStream.docx", FileMode.Create, FileAccess.ReadWrite))
        Watermarker.Create(watermarkerContext)
            .From(streamIn)
            .To(streamOut, SaveFormat.Docx)
            .Execute();
}
