[reportlab-users] Reportlab footer issue

[Asif Jamadar]

May be this one helps you,

def HeaderFooter(canvas, doc): 
    canvas.saveState()    
    
    canvas.setFont('Times-Roman', 9)
    canvas.drawString(280, 43, "Page %d" % doc.page)
    canvas.drawImage("rezilabs.bmp", 43,820, width=1.3*inch,height=0.2*inch)
    canvas.drawImage("RezayatLogo.bmp", 470,820, width=1.5*inch,height=0.3*inch)

    canvas.restoreState()



and your main function will be

doc.build(Document, onLaterPages=HeaderFooter)

Hi,



I need to generate invoices in PDF. Each invoioce has a footer. Also pages are to be numbered in the style Page X of Y.

Inorder to achieve this I provide my own functions for onFirstPage, onLaterPages, and canvasmaker in doc.build:

doc.build(elements,
          onFirstPage=myFooter,
          onLaterPages=myFooter,
          canvasmaker=NumberedCanvas)


These functions work as expected. However, in order to format the output I need access to elementary attributes of the document: pagesize and margins.

For example I need to put page numbers to the bottom of the page in the middle. I can nail it down to fixed coordinates, which works without any problems, but I don't like this approach, because the document template can change.

I need to be able to get these attributes from canvas, which all the abovementioned functions get as one of their arguments.

I jus can't figure out how to read these attributes. For example leftmargin is mentioned in the whole documentation just once - where document template is created.

I suppose pagesize and margins must be stored somewhere - how can I read them?
