[reportlab-users] Can you help my Reportlab program?

Hi 方建,

You will reach a wider audience if you join the reportlab-users list

However, I think I may be able to assist you.

1) The Paragraph class is designed to cooperate with the Frame/DocTemplate 
classes and is a sub-class of Flowable.

2) Normally the Paragraph is instantiated, wrapped and then drawn. The wrap 
method allows the user to specify how much space is available and also determine 
how much space will be used. The draw method then allows the user to determine 
whether or not the paragraph should be drawn at the current point in the Frame.


3) More concretely

    pa = Paragraph('some texts........', some_style)
    w, h = pa.wrap(availableWidth,availableHeight)
    # w and h now hold the width and height that the paragraph expects to use
    # *NB* when you draw the paragraph it will take the coordinates you give
    # to the draw method as the left lower corner of a w x h rectangle

    # to get the top left corner at 370, 225 we have to subtract h from 225
    pa.draw(canvas,370,225-h)

hope this helps
