如果文档为A3格式和横向，如何使用C#将Word文件页面转换为png图像

Question

我使用了这段代码。它运行良好，但仅适用于word文档A4格式。当格式为A3和横向时，图像右侧裁剪约15%。

附言：如果格式为A3和纵向，图像会向下裁剪约15%。

var docPath = Path.Combine(startupPath, filename1);
var app = new Microsoft.Office.Interop.Word.Application();
MessageFilter.Register();
app.Visible = true;
var doc = app.Documents.Open(docPath);
doc.ShowGrammaticalErrors = false;
doc.ShowRevisions = false;
doc.ShowSpellingErrors = false;
if (!Directory.Exists(startupPath + "\" + filename1.Split('.')[0]))
{
Directory.CreateDirectory(startupPath + "\" + filename1.Split('.')[0]);
}
//Opens the word document and fetch each page and converts to image
foreach (Microsoft.Office.Interop.Word.Window window in doc.Windows)
{
foreach (Microsoft.Office.Interop.Word.Pane pane in window.Panes)
{
for (var i = 1; i <= pane.Pages.Count; i++)
{
var page = pane.Pages[i];
var bits = page.EnhMetaFileBits;
var target = Path.Combine(startupPath + "\" + filename1.Split('.')[0], string.Format("{1}_page_{0}", i, filename1.Split('.')[0]));
try
{
using (var ms = new MemoryStream((byte[])(bits)))
{
var image = System.Drawing.Image.FromStream(ms);
var pngTarget = Path.ChangeExtension(target, "png");
image.Save(pngTarget, ImageFormat.Png);
}
}
catch (System.Exception ex)
{ }
}
}
}
doc.Close(Type.Missing, Type.Missing, Type.Missing);
app.Quit(Type.Missing, Type.Missing, Type.Missing);
MessageFilter.Revoke();
