PDF格式的圖像問題

正在嘗試使用下面的鏈接 http://threebit.net/mail-archive/itext-questions/msg00436.html PDF格式的圖像問題

轉換pdftoimage，但我得到這個錯誤如何獲得此代碼工作？「找不到類型或名稱空間名稱PdfDecoder'」正在尋找開源代碼。

在服務器這個ghostscript的力工作， http://www.codeproject.com/KB/webforms/aspnetpdfviewer.aspx

幫助我。

你可以試試這個.....

pdfDoc = (Acrobat.CAcroPDDoc) 
Microsoft.VisualBasic.Interaction.CreateObject("Ac roExch.PDDoc", ""); 
int ret = pdfDoc.Open(inputFile); 
if (ret == 0) 
{ 
    throw new FileNotFoundException(); 
} 
// Get the number of pages (to be used later if you wanted to store that information) 
int pageCount = pdfDoc.GetNumPages(); 
// Get the first page 
pdfPage = (Acrobat.CAcroPDPage)pdfDoc.AcquirePage(0); 
pdfPoint = (Acrobat.CAcroPoint)pdfPage.GetSize(); 
pdfRect = (Acrobat.CAcroRect) 
Microsoft.VisualBasic.Interaction.CreateObject("Ac roExch.Rect", ""); 
pdfRect.Left = 0; 
pdfRect.right = pdfPoint.x; 
pdfRect.Top = 0; 
pdfRect.bottom = pdfPoint.y; 
// Render to clipboard, scaled by 100 percent (ie. original size) 
// Even though we want a smaller image, better for us to scale in .NET 
// than Acrobat as it would greek out small text 
pdfPage.CopyToClipboard(pdfRect, 0, 0, 100); 
IDataObject clipboardData = Clipboard.GetDataObject(); 
if (clipboardData.GetDataPresent(DataFormats.Bitmap)) 
{ 
    Bitmap pdfBitmap = 
    (Bitmap)clipboardData.GetData(DataFormats.Bitmap); 
}

請看看這個鏈接more info

你可以試試這個也

SautinSoft.PdfFocus f = new SautinSoft.PdfFocus(); 
f.ConvertPdfToImage(@"c:\sample.pdf", @"c:\pages\", 
SautinSoft.PdfFocus.eImageFormat.Jpeg, 200);
