However, this method will adjust the picture size to fit on a single sheet of paper. This article shows you how to print a large picture on multiple sheets of paper.

From this ratio, you can calculate the number of pages required to print the picture completely. With each page, you use the PrintPicture method to print the maximum image on that sheet. Keep repeating this process on each successive page until the picture is completely printed. The next section shows you how to create a sample program to demonstrate this technique. Step-by-Step Example -------------------- 1. Start a new project in Visual Basic. Form1 is created by default. 2. Add three CommandButtons, a Common Dialog control, and a Picture control to Form1. 3. Copy the following code to the Code window of Form1: Option Explicit Const constMaxValue = 32767 Dim lngPrinterWidth As Long, lngPrinterHeight As Long Dim lngPictureWidth As Long, lngPictureHeight As Long Dim lngXCoor As Long, lngYCoor As Long Dim sngWidthRatio As Single, sngHeightRatio As Single Dim intPageWidth As Integer, intPageHeight As Integer Dim bytWidthCount As Byte, bytHeightCount As Byte Private Sub Form_Load() Command1.Caption = "Load Picture" Command2.Caption = "Print Single Page" Command3.Caption = "Print Multiple Pages" End Sub Private Sub Command1_Click() 'Opens the common dialog box so you can select a picture file 'to load into the Picture object. Dim picFile As Picture CommonDialog1.Filter = "JPEG files|*.jpg|BMP files|*.bmp" CommonDialog1.ShowOpen If CommonDialog1.filename <> "" Then Set picFile = LoadPicture(CommonDialog1.filename) Set Picture1.Picture = picFile Form1.Height = Picture1.Height + 1700 Form1.Width = Picture1.Width + 1400 Picture1.Left = 700 Picture1.Top = 700 End If End Sub Private Sub Command2_Click() 'Print the picture on a single sheet. Picture object automatically 'adjusts picture size to fit into a single sheet. Printer.PaintPicture Picture1.Picture, lngXCoor, lngYCoor Printer.EndDoc MsgBox "Done Sending Info to Printer" End Sub Private Sub Command3_Click() 'Print the picture on multiple sheets. 'Load the dimensions of the image and printer into memory lngPictureWidth = Picture1.Picture.Width lngPictureHeight = Picture1.Picture.Height lngPrinterWidth = Printer.Width lngPrinterHeight = Printer.Height 'Calculate the ratios sngWidthRatio = lngPictureWidth / lngPrinterWidth sngHeightRatio = lngPictureHeight / lngPrinterHeight 'Calculate how many pages are required to print the picture intPageWidth = constMaxValue - Int(constMaxValue - sngWidthRatio) intPageHeight = constMaxValue - Int(constMaxValue - _ sngHeightRatio) For bytWidthCount = 1 To intPageWidth 'Calculate the x-offset lngXCoor = -lngPrinterWidth * (bytWidthCount - 1) For bytHeightCount = 1 To intPageHeight 'Calculate the y-offset lngYCoor = -lngPrinterHeight * (bytHeightCount - 1) 'Use the Paint Picture method to print the picture Printer.PaintPicture Picture1.Picture, _ lngXCoor, _ lngYCoor, _ lngPictureWidth, _ lngPictureHeight 'start a new page Printer.NewPage Next bytHeightCount Next bytWidthCount Printer.EndDoc MsgBox "Done Sending Info to Printer" End Sub 4. Press the F5 key to run the program. Click Load Picture to open the Common Dialog, and choose a picture file. Click Print Single Page to print the picture to a single page or Print Multiple Pages to print to multiple pages.
