Printing image with PrintDocument how to adjust the image to fit paper size

Question

In C   I am trying to print an image using PrintDocument class with the below code  The image is of size 1200 px width and 1800 px height  I am trying to print this image in a 4 6 paper using a small zeebra printer  But the program is printing only 4 6 are of the big image  that means it is not adjusting the image to the paper size          PrintDocument pd   new PrintDocument         pd PrintPage     sender  args    gt                    Image i   Image FromFile  C   tesimage PNG               Point p   new Point 100  100              args Graphics DrawImage i  10  10  i Width  i Height                pd Print      When i print the same image using Window Print  right click and select print  it is scaling automatically to paper size and printing correctly  that means everything came in 4 6 paper   How do i do the same in my C  program

Agree with TonyM and BBoy - this is the correct answer for original 4 6 printing of label    args PageBounds    This worked for me for printing Endicia API service shipping Labels   private void SubmitResponseToPrinter ILabelRequestResponse response                PrintDocument pd   new PrintDocument            pd PrintPage     sender  args    gt                        Image i   Image FromFile response Labels 0  FullPathFileName Trim                 args Graphics DrawImage i  args PageBounds                      pd Print

all these answers has the problem  that s always stretching the image to pagesize and cuts off some content at trying this  Found a little bit easier way   My own solution only stretch is this the right word   if the image is to large  can use multiply copies and pageorientations                  PrintDialog dlg   new PrintDialog                 if  dlg ShowDialog      true                                BitmapImage bmi   new BitmapImage new Uri strPath                     Image img   new Image                    img Source   bmi                   if  bmi PixelWidth  lt  dlg PrintableAreaWidth                               bmi PixelHeight  lt  dlg PrintableAreaHeight                                        img Stretch   Stretch None                      img Width   bmi PixelWidth                      img Height   bmi PixelHeight                                      if  dlg PrintTicket PageBorderless    PageBorderless Borderless                                        img Margin   new Thickness 0                                     else                                       img Margin   new Thickness 48                                     img VerticalAlignment   VerticalAlignment Top                  img HorizontalAlignment   HorizontalAlignment Left                   for  int i   0  i  lt  dlg PrintTicket CopyCount  i                                          dlg PrintVisual img   quot Print a Image quot

The solution provided by BBoy works fine  But in my case I had to use   e Graphics DrawImage memoryImage  e PageBounds     This will print only the form  When I use MarginBounds it prints the entire screen even if the form is smaller than the monitor screen  PageBounds solved that issue  Thanks to BBoy

The parameters that you are passing into the DrawImage method should be the size you want the image on the paper rather than the size of the image itself  the DrawImage command will then take care of the scaling for you  Probably the easiest way is to use the following override of the DrawImage command   args Graphics DrawImage i  args MarginBounds     Note  This will skew the image if the proportions of the image are not the same as the rectangle  Some simple math on the size of the image and paper size will allow you to create a new rectangle that fits in the bounds of the paper without skewing the image

Not to trample on BBoy s already decent answer  but I ve done the code that maintains aspect ratio   I took his suggestion  so he should get partial credit here   PrintDocument pd   new PrintDocument    pd DefaultPageSettings PrinterSettings PrinterName    Printer Name   pd DefaultPageSettings Landscape   true    or false  pd PrintPage     sender  args    gt        Image i   Image FromFile   C          image jpg        Rectangle m   args MarginBounds       if   double i Width    double i Height  gt   double m Width    double m Height     image is wider               m Height    int   double i Height    double i Width    double m Width             else               m Width    int   double i Width    double i Height    double m Height             args Graphics DrawImage i  m      pd Print
