    Introduction

    This program provides a framework for a single page printing program. Its features include

    1. a WYSIWYG interface with Zooming capability: from 75% to 150% , with FitWidth and FitHeight mode
    2. Allowing user to set margins using the Page Setup Dialog
    3. Using double buffers to reduce flickering
    4. Automatically updating the page size when it is changed by the user using the Print Setup Dialog
    5. Rulers with markings that will change according to the scale and position of the paper
    6. Scrolling of Text

    To suit your drawing needs, edit the DrawHere method in the TextBmpView.cpp file. This function will pass 3 arguments to you:

    1. PaperRect : The paper rectangle in logical coordinates.
    2. PrintableRect : The region where your printer will print (This is slightly smaller than the paper rect).
    3. MarginsRect : The margin rectangle in logical coordinates. (This area is defined by the user, and you might choose to ignore it)
    void CTextbmpView::DrawHere(CDC* pDC,CRect PaperRect, 
                                CRect PrintableRect,CRect MarginsRect) 
    { 
    	/////////////////////////////////////////  
    	//ADD Drawing code here!!!                 
    }  
    

    These 3 arguments will vary according to the paper size currently selected, but will not vary with respect to the current zoom mode. Your code will have to draw according to these dimensions, within the rectangular area given. You can use the MFC drawing functions like DrawText, LineTo, CreateFont etc. to create your drawing.

    Units

    1. The units are in twips (1 inch = 1440 twips), so to draw a 1 inch line, do the following:
      pDC->MoveTo(0,-2000); pDC->LineTo(1440,-2000);
    2. The y-values of most points are negative. The lower the point, the smaller/more negative is the y-value.
    3. The origin (0,0) is located at the top-left of the dotted rectangle (printable area). Typical values for the PrintableRect of an A4 sized paper is top = 0, left = 0, right = 11568, bottom = -15876.

    The display

    1. The printable area is represented by the dotted rectangle.
    2. The paper rectangle is indicated by the white area in gray background.
    3. The margins are shown as the gray regions on the ruler.
    4. To convert a point clicked on the screen into a logical point on the paper, use the ScreenToPaper method. For an example, look at the CTextBmpView::OnLButtonDown method. There is another method PaperToScreen which will convert a point on the paper to a point on the screen.

    Limitations

    This program may not work with large paper size: e.g. A3 sized paper

    Generalzoom/print preview PinmemberArun R29-Apr-03 4:57 
    Eek! | :eek: I have a scroll view in my application, where I display tree (each node in tree is represented by a button object with bitmap embedded over it).
     
    When I try to print the tree, only nodes which are visible in the display screen are getting printed. All other nodes are not getting printed and not being shown in the print preview.
     
    Related to the same, I want to implement zoom feature by which I can compress the whole tree and display in the display area.
     
    How to proceed to achieve the same?
