private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            //PrinterResolution pr = new PrinterResolution();

            //pr.X = (int)img.HorizontalResolution;

            //pr.Y = (int)img.VerticalResolution;

            //e.PageSettings.PrinterResolution = pr;

            //e.Graphics.DrawImage(img,new Point(0, 0));

            int X = 0;//printDocument1.DefaultPageSettings.Margins.Left;
            int Y = 0;// printDocument1.DefaultPageSettings.Margins.Top;
            int Genislik = pictureBox1.Width;

            e.Graphics.DrawImage(pictureBox1.Image, X, Y, Genislik, Yukseklik);

Answer 1

To draw your image to a certain size, use a DrawImage overload that takes a destination size.

Answer 2

draw image size is pixel ? right ?

So when i use 838 and 1169 pixel for drawimage, printed picture fit for A4. But bad quality.

When i use 2480 pixel widht and 3507 for drawimage, printed picture is so huge for A4. 25% picture be printed with A4. But best quality. Also at photoshop picture have 21cm width and 30 cm hegiht when resolution 2480 pixel width and 3507 pixel height.

How can i use 2480 pixel widht and 3507 pixel height to printed picture fit for A4 ?

To draw your image to a certain size, use a DrawImage overload that takes a destination size.  Printer display units are 1/100 inch.

Answer 4

i dont understand. if there were a solution, can you show me as code ?

Answer 5

Can you find DrawImage in the help files?  Use the overload that draws the image to a destination rectangle.  It is listed as DrawImage(image, Rectangle) and there is example code.

Answer 6

There are 30 way to use drawimage. Which one should i use ? And i couldnt see any way to use resolution at drawimage.

There are Rectangle, point, size, margins and image.

Also there is widht and height. widht and height as pixel. I got problem at here.

When i use 2480 pixel widht and 3507 for drawimage(300 dpi), printed picture is so huge for A4. 25% picture be printed with A4. But best quality. Also at photoshop picture have 21cm width and 30 cm hegiht when resolution 2480 pixel width and 3507 pixel height.

Answer 7

Use the one I suggested in my last post.  If you couldn't find the code here it is:

e.Graphics.DrawImage(pictureBox1.Image, e.PageBounds)
