Print error

Question

Hello,

I hope someone can help me. I try to print an image and to draw a yellow rectangle with transparency, but it gives me a reading or writing protected memory error.

Here's the simplified code that reproduces the error:

 

private void PrintImage()
{
   try
   {
      printDocument1.DocumentName = "Test";
      printDocument1.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
      printDocument1.Print();
   }
   catch (Exception e)
   {
      //reading or writing protected memory error
   }
}

 

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) {
   if (!e.Cancel)
   {
      Image printImg = Bitmap.FromFile("d:\\temp\\img.gif");   //PRINT1
      //Image printImg = new Bitmap(1096, 2200);                 //PRINT2

      e.Graphics.DrawImage(printImg, 0, 0, 800, 1000); 

      SolidBrush b = new SolidBrush(Color.FromArgb(110, Color.Yellow));  //BRUSH 1
      //SolidBrush b = new SolidBrush(Color.Yellow); //BRUSH 2
      e.Graphics.FillRectangle(b, 50, 50, 100, 100);
     
      e.HasMorePages = false;
   }
   else
      e.Cancel = true;
}

 

If I call the function PrintImage () that causes the error.

If I replace the line PRINT1 by PRINT2
OR
if I replace the line BRUSH1 by BRUSH2
= 
the print works.


Thank you for your help.
