I am using PdfSharp 1.32.3057.0 GDI+ in a .Net service on Windows 2008 R2 to convert 1-6 page tiff files to pdf. A few of the output pdf files get an "insufficient data for an image" error in Adobe reader. If I reconvert the same image then it will render with no problem.
I have reproduced the issue in test code that just loops converting the same file in my dev environment - I normally get 1-4% errors. Any ideas what may be wrong? A workaround or even a quick way of detecting a problem image would help.
Code:
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using PdfSharp.Drawing;
using PdfSharp.Pdf;
namespace TestPdfConvert
{
class Program
{
static void Main(string[] args)
{
for (int loop = 1; loop <= 100; loop++)
{
System.Console.WriteLine(loop);
ConvertImage();
}
System.Console.ReadLine();
}
private static void ConvertImage()
{
using (Image inputImage = Image.FromFile(@"D:\test\input\test.tif"))
{
using (PdfDocument doc = new PdfDocument())
{
for(int frameNo =0; frameNo<inputImage.GetFrameCount(FrameDimension.Page); frameNo++)
{
inputImage.SelectActiveFrame(FrameDimension.Page,frameNo);
using (MemoryStream memoryStream = new MemoryStream())
{
inputImage.Save(memoryStream, ImageFormat.Bmp);
using (XImage outputImage = Image.FromStream(memoryStream))
{
PdfPage page = new PdfPage();
page.Width = outputImage.PointWidth;
page.Height = outputImage.PointHeight;
doc.AddPage(page);
using (XGraphics xgraphics = XGraphics.FromPdfPage(page))
{
xgraphics.DrawImage(outputImage, 0, 0);
}
}
}
}
doc.Save( string.Format(@"D:\test\output\test_{0}.pdf",System.DateTime.Now.ToString("HH_mm_ss.fff")) );
}
}
}
}
}
