QuestionBitmap.SelectActiveFrame Pin
H@is@here31-May-11 12:53
memberH@is@here31-May-11 12:53 
Hi everyone,

I would like to know if someone have experienced slow issues with Bitmap.SelectActiveFrame in a 64 bit system,
or why is the method so much slower in a 64 bit system than in a 32 bit?

Here is a sample code that I have used to test:

Bitmap m_bmp = new Bitmap("C:\\01.tif");
           String m_Start = DateTime.Now.ToString("hh:mm:ss");
           System.Diagnostics.Debug.WriteLine("Started at: " + m_Start);
           for (Int32 a = 0; a < 22; a++)
           { m_bmp.SelectActiveFrame(FrameDimension.Page, a); }
           String m_Finish = DateTime.Now.ToString("hh:mm:ss");
           System.Diagnostics.Debug.WriteLine("Finished at: " + m_Finish.ToString());


The 01.tif file is a black & white image with 1bpp and 23 pages with 300dpi.
Test made with Windows7 VS2010 .NetFramework 4.0 32 bit: Less than 1 second.
Test made with Windows7 VS2010 .NetFramework 4.0 64 bit: 6 seconds.
This is really a lot.
Can someone be kind to help me ?

Thank you. Best regards.
