wmz 文件转为 gif 或 jpg

Question

如何在 C# 中将“wmz”文件转换为“gif”或“jpg”文件？

Answer 1

WMZ 是一个压缩的 Windows 图元文件，您可以先解压，然后再解压转换为所需格式（不要忘记处置所有那些 Image 实例（MSDN 示例中未完成）。

Answer 2

感谢您的帮助。我可以解压缩“wmz”文件并将其转换为 wmf 文件。代码是

public String DeCompressWMZFile(String wmzFile)
{
    MemoryStream decompressStream = new MemoryStream(File.ReadAllBytes(wmzFile));
    GZipStream gzipStream = new GZipStream(decompressStream, CompressionMode.Decompress);
    MemoryStream outStream = new MemoryStream();
    int readCount;
    byte[] data = new byte[2048];
    do
    {
        readCount = gzipStream.Read(data, 0, data.Length);
        outStream.Write(data, 0, readCount);
    } while (readCount == 2048);
    String imgFile = Path.GetDirectoryName(wmzFile) + "\\" + Path.GetFileNameWithoutExtension(wmzFile) + ".wmf";
    File.WriteAllBytes(imgFile, outStream.GetBuffer());
    // Then add the code to create a new word document and insert 
    return imgFile;
}

将 WMZ 转换为 GIF/PNG/JPG/等：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://link1.ru/image.wmz");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (Stream inputStream = response.GetResponseStream()) 
{
    using (GZipStream gzipStream = new GZipStream(inputStream, CompressionMode.Decompress))
    {
        Image i = Image.FromStream(gzipStream);
        i.Save("1.gif", ImageFormat.Gif);
    }
}
