使用C＃将Word文件页面转换为jpg图像
如何将word文档页面转换为特定图像？
我使用以下代码将其转换为.tiff图像
object varMissing = Type.Missing; object varFalseValue = false; object varTrueValue = true; Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application(); word.ActivePrinter = "Microsoft XPS Document Writer"; object fileName = startupPath + "\" + filename1; object falseValue = false; object trueValue = true; object missing = Type.Missing; word.Visible = true; word.Activate(); Document doc = word.Documents.Open(ref fileName, ref missing, ref falseValue, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); doc.Activate(); object PrintToFile = true; object OutputFileName = startupPath + "\" + filename1.Split('.')[0] + ".tif"; doc.PrintOut(ref varMissing, ref varFalseValue, ref varMissing, ref OutputFileName, ref varMissing, ref varMissing, ref varMissing, ref varMissing, ref varMissing, ref varMissing, ref PrintToFile, ref varMissing, ref varMissing, ref varMissing, ref varMissing, ref varMissing, ref varMissing, ref varMissing); doc.Close(ref varMissing, ref varMissing, ref varMissing); word.Quit(ref varMissing, ref varMissing, ref varMissing); //Multi to Single MemoryStream ms; Image myImage; FileStream fs = new FileStream(startupPath + "\" + filename1.Split('.')[0] + ".tif", FileMode.Open); fs.Seek(0, SeekOrigin.Begin); //Here I am getting error.... myImage = Image.FromStream(fs, true, false); Guid myGuid = myImage.FrameDimensionsList[0]; FrameDimension myDimension = new FrameDimension(myGuid); int myPageCount = myImage.GetFrameCount(myDimension); for (int i = 0; i < myPageCount; i++) { ms = new MemoryStream(); myImage.SelectActiveFrame(myDimension, i); myImage.Save(string.Format(startupPath + "\" + filename1.Split('.')[0] + ".tif", i), ImageFormat.Tiff); } fs.Close();
但是当我试图将文件流转换为Image时，它给出了我的错误
Parameter is not valid.
有没有其他方法将word文件转换为图像文件？ 我不能使用市场上出售的dll来销售，但我需要使用Microsoft's core interop dll. 所以，任何人都可以建议我将.doc文件转换为.jpg的链接或方法。
您可以使用它为我工作的波纹管代码将Doc文件转换为图像。
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();
我想我在@WarLock提供的代码中发现了错误。 我更改了它的一些部分，只使用一个文件：
