将word文档另存为图像 [英] Saving a word document as an image

问题描述

我使用以下代码将Word文档转换为图像文件。但是图片看起来太大了，而且内容不合适 - 有没有办法渲染图片或将图片保存到大小？

I am using the below code to convert a Word Doc into an image file. But the picture appears too big, and the contents don't fit - is there a way to render the picture or save the picture to size?

    private void btnConvert_Click(object sender, EventArgs e)
    {
        if (string.IsNullOrEmpty(txtFileName.Text))
        {
            MessageBox.Show("Choose a document to convert", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            txtFileName.Focus();
            return;
        }

        ApplicationClass wordApp = new ApplicationClass();
        object objectMissing = Missing.Value;

        try
        {
            object fileName = txtFileName.Text;
            FileStream fs = new FileStream(fileName.ToString(), FileMode.Open, FileAccess.Read);
            Byte[] data = new Byte[fs.Length];
            fs.Read(data, 0, data.Length);

            Document doc = wordApp.Documents.Open(ref fileName, ref objectMissing, ref objectMissing, ref objectMissing, ref objectMissing, ref objectMissing, ref objectMissing,
                                   ref objectMissing, ref objectMissing, ref objectMissing, ref objectMissing, ref objectMissing, ref objectMissing,
                                   ref objectMissing, ref objectMissing, ref objectMissing);


            byte[] range = (byte[]) wordApp.ActiveDocument.Content.EnhMetaFileBits;
            if (range != null)
            {
                MemoryStream ms = new MemoryStream(range);
                Metafile mf = new Metafile(ms);
                picImage.Height = mf.Height;
                picImage.Width = mf.Width;
                mf.Save("c:\\test.png", ImageFormat.Png);
                picImage.Image = Image.FromFile("c:\\test.png");
            }
        }
        finally
        {
            wordApp.Quit(ref objectMissing, ref objectMissing, ref objectMissing);
        }
    }

推荐答案

它结果非常简单：

    private void renderImage(byte[] imageData)
    {
        using (MemoryStream ms = new MemoryStream(imageData))
        {
            Image image = Image.FromStream(ms);
            picImage.Image = image;
        }
    }

这是将第一页显示为图像，但是它应该很容易呈现其他页面。

This is showing the first page as an image, but it should be easy enough to render the other pages also.
