[reportlab-users] Draw images with canvas and use SimpleDocTemplate

[slothy Rulez a lot]

Hi! [ ]

I'm newbee using reportlab, I'm writing pdfs with reportlab inside a django
view, they are very simple, the header, the contents and the footer.

I'm using SimpleDocTemplate wich fits very well, to draw tables in the
contents, the footer and the header are drwan using:

build([data], onFirstPage=drawPageFrame, onLaterPages=drawPageFrame).
My question is, How can I draw a image like using Canvas.drawImage(...)? I
need a "floating" image... positioned over the text where I want, and with
SimpleDocTemplate I don't have a Canvas object to do this.

Thaks.

Searching I have found this:

The platypus layout stuff uses flowables. Packers normally set the attribute
canv onto each flowable when it is being wrapped, split or drawn ie around
the wrap, split and draw methods. Inside those methods you have access to
the canvas using the canv attribute of self.

¿¿How can this be used??

Ummmm, more stuff to test:

flowables.Macro
flowables.CallerMacro

This is my test ¿wrong?

# -*- coding: utf-8 -*-
from reportlab.lib.pagesizes import A4, landscape, portrait
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.platypus import Table, Flowable, SimpleDocTemplate,
Paragraph, Spacer, Image
from reportlab.lib import randomtext
from reportlab import platypus

import os,random

styles = getSampleStyleSheet()
path = os.path.realpath(os.path.dirname(__file__))

def drawPageFrame(canvas, doc):
    canvas.saveState()
    canvas.drawImage(path+"/ujiPDF.jpg",50,50,57,57)
    canvas.restoreState()

doc = SimpleDocTemplate("salida.pdf",pagesize=A4)

elementos = []

com = 'canvas.drawImage("'+path+'/ujiPDF.jpg",100,100,57,57)'
print com
elementos.append(platypus.flowables.Macro('canvas.saveState()'))
print platypus.flowables.Macro(com)
elementos.append(platypus.flowables.Macro(com))
elementos.append(platypus.flowables.Macro('canvas.restoreState()'))

para = Paragraph(randomtext.randomText(randomtext.PYTHON,20),
styles["Normal"])
elementos.append(para)

doc.build(elementos,onFirstPage=drawPageFrame, onLaterPages=drawPageFrame)
This is the Macro aproach...clean exit but without the second image....


Thanks.
