Encapsulate a printed public category and share it with kids shoes.

The ImagePrinter class is a encapsulated printing class. before printing, you must call the public bool PrinterReady (Bitmap printContent) method to input an image file. Then, you can call PrintView () to print the image and call PrintOut () you can print it. The ExpressPrinter class is an instance that calls the ImagePrinter print encapsulation class. It is designed to show how to use GDI + to draw the content and font to be printed. ========================================================== ======== Using System; using System. collections. generic; using System. drawing. imaging; using System. linq; using System. text; using System. drawing; using System. windows. forms; using System. drawing. printing; using Lib. biz. clientService; using Lib. utility. extension; using PrintOrder. utility; namespace PrintOrder. expressPrinter. printDoc {// <summary> // print the image content /// </summa Ry> public class ExpressPrinter {// <summary> /// create an instance of the printed object of the express order /// </summary> /// <param name = "printerName"> printer name, if it is null, the default printer </param> /// <param name = "template"> Print template </param> /// <param name = "items"> Print item </param> /// <param name = "isCoordinateRule"> whether to print the positioning ruler </param> public ExpressPrinter (string printerName, print_Template template, List <Print_Item> items, bool isCoordinateRule) {m_template = templat E; m_items = items; m_print = new ImagePrinter (printerName); response = isCoordinateRule; InitPrinter () ;}# region variable private Print_Template m_template; private List <Print_Item> m_items; private Bitmap m_bitmap = new Bitmap (10, 10); private Brush m_brush = new SolidBrush (Color. black); private ImagePrinter m_print = null; private bool m_isCoordinateRule = false; # endregion // <summary>/ // Set the paper size /// </summary> private void SetPrintPageSize () {// use 1 inch to recreate the drawing using (Graphics g = Graphics. fromImage (m_bitmap) {// note: the unit is SizeF sizeF = new SizeF (CommonMethod. pixelsToInches (m_template.Width, g. dpiX) * 100, CommonMethod. pixelsToInches (m_template.Height, g. dpiY) * 100); Size size Size = Size. ceiling (sizeF); m_print.DefaultPaperSize = new PaperSize ("NewPage", size. width, size. height );} M_print.DefaultMargins = new Margins (0, 0, 0, 0); m_print.PrintDocName = string. format ("{0} ({1})", m_template.TemplateName, m_template.Modifier );} /// <summary> /// initialize before printing /// </summary> private void InitPrinter () {SetPrintPageSize (); // set the paper size m_bitmap = new Bitmap (m_template.Width, m_template.Height); Func <Print_Item, Font> getFont = (o => {FontStyle fontStyle = FontStyle. regular; if (o. fontBo Ld = 1) fontStyle = fontStyle | FontStyle. bold; if (o. fontItalic = 1) fontStyle = fontStyle | FontStyle. italic; if (o. fontStrikeout = 1) fontStyle = fontStyle | FontStyle. strikeout; if (o. fontUnderline = 1) fontStyle = fontStyle | FontStyle. underline; Font font = new Font (o. fontName, o. fontSize, fontStyle); return font;}); using (Graphics g = Graphics. fromImage (m_bitmap) {g. pageUnit = Graph IcsUnit. pixel; // fill in the data to the image template (the position must be measured when the image template is created) g. fillRectangle (Brushes. white, 0f, 0f, m_template.Width, m_template.Height); // test the paper size. // this. drawTestRectangle (g); if (m_isCoordinateRule) {TestPageSize (g);} foreach (Print_Item item in m_items) {g. drawString (item. text, getFont (item), Brushes. black, new RectangleF (item. offset_X + m_template.Offset_X // set the global offset X coordinate, item. offset_Y + m_template.Of Fset_Y // sets the global offset Y coordinate, item. width, item. height);} g. dispose ();} // m_bitmap.Save (@ "D: \ WorkTest \ temp \ express.jpg"); m_print.PrinterReady (m_bitmap);} private void DrawTestRectangle (Graphics g) {g. pageUnit = GraphicsUnit. pixel; SizeF size = new SizeF (Utility. commonMethod. millimetersToPixel (30, g. dpiX), Utility. commonMethod. millimetersToPixel (30, g. dpiY); g. drawRectangle (new Pen (Color. black, 1 ), 50, 50, size. width, size. height);} // <summary> // print the ruler // </summary> private void TestPageSize (Graphics g) {g. pageUnit = GraphicsUnit. pixel; // eight positioning boxes Size = new size (20, 20); Point ltop = new Point (); Point rtop = new Point (m_template.Width-Size. width, 0); Point ldwn = new Point (0, m_template.Height-size. height); Point rdwn = new Point (m_template.Width-size. width, m_template.H Eight-size. height); Point tmdio = new Point (m_template.Width/2-size.Width/2, 0); Point dmdio = new Point (m_template.Width/2-size. width/2, m_template.Height-size. height); Point lmdio = new Point (0, m_template.Height/2-size. height/2); Point rmdio = new Point (m_template.Width-size. width, m_template.Height/2-size. height/2); // Point mdio = new Point (m_template.Width/2-size. wid Th/2, m_template.Height/2-size. height/2); // the upper left and lower right limit rectangle Size tRec = new Size (m_template.Width/4, 10); Size lRec = new Size (10, m_template.Height/4 ); point ldRec = new Point (0, lmdio.
