python通过reportlab实现图片转换pdf

Reportlab是用python开发的生成pdf的工具包，它是一个开源软件。

#!/usr/bin/env python
 
import os
import sys
from reportlab.lib.pagesizes import A4, landscape
from reportlab.pdfgen import canvas
f = sys.argv[1]
filename = ''.join(f.split('/')[-1:])[:-4]
f_jpg = filename+'.jpg'
print f_jpg
def conpdf(f_jpg):
    f_pdf = filename+'.pdf'
    (w, h) = landscape(A4)
    c = canvas.Canvas(f_pdf, pagesize = landscape(A4))
    c.drawImage(f, 0, 0, w, h)
    c.save()
    print "okkkkkkkk."
 
conpdf(f_jpg)
