Error Out of memory when dealing with tiff images in c# 2015

Question

Hello

 

I'm working on c#

 

Has a problem when dealing with images of type Tiff in the following code:

 

public static Bitmap ResizeImage(Image pic, int w, int h)

{

Bitmap returnImag = new Bitmap(w, h);

returnImag.SetResolution(pic.HorizontalResolution, pic.VerticalResolution);

using (Graphics graphics = Graphics.FromImage(returnImag))

{

graphics.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;

graphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;

graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;

graphics.DrawImage(pic, 0, 0, returnImag.Width, returnImag.Height);

}

return returnImag;

}

 

Note that if i put a message code to disable the implementation more than ten seconds between the image and the following image the previous code works

 

Do you have any suggestion to do code without placing a message

 

DialogResult result = MessageBox.Show("?? ???? ?????????????", " ????? ", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

if (result == DialogResult.Yes)

{ }

 

Thank you
