printing form in C#

Question

How do I scale image of Windows form down so it fits printed page?

Louis Klauder · Answer

I forgot that my application already contained a handler and function: this .PrintDocument_inst.PrintPage += new System.Drawing.Printing. PrintPageEventHandler ( this .k_line_PrintPage); private void k_line_PrintPage( object sender PrintPageEventArgs ppea) which latter includes the following code block in which I was able to alter the value of _scale_f to obtain the result I needed float _scale_f; if ( PrintDialog_inst != null ) { string str_printer_name = PrintDialog_inst.PrinterSettings.PrinterName.ToString ( ); switch ( str_printer_name ) { case Adobe PDF : _scale_f = 0.85F; break ; case Microsoft XPS Document Writer : _scale_f = 0.80F; // 0.85F; break ; default : _scale_f = 0.94F; // 1.0f; // 0.59F; // break ; } } else // case of print preview { _scale_f = 0.59F; // 0.82F; } if ( _scale_f != 1.0F ) ppea.Graphics.ScaleTransform ( _scale_f _scale_f ); ppea.Graphics.DrawImage ( plot_metafile leftMargin topMargin ); ppea.HasMorePages = ( --n_pages_still_to_print > 0 ? true : false );

I never tried in Windows forms but a suggestion can you try with SizeMode property on picturebox. Usually you can set either to Auto or stretch so that it fits to the window/control . See other properties in below link. http://msdn.microsoft.com/en-us/library/system.windows.forms.pictureboxsizemode(v=vs.110).aspx
