Question

그림을 PDF 파일로 저장하려고합니다. 내 코드는 다음과 같습니다 ...

import sys 
import xlrd 
from PIL import Image 
import ImageEnhance 
from reportlab.platypus import * 
from reportlab.lib.styles import getSampleStyleSheet 
from reportlab.rl_config import defaultPageSize 
PAGE_HEIGHT=defaultPageSize[1] 

styles = getSampleStyleSheet() 

Title = "Integrating Diverse Data Sources with Gadfly 2" 

Author = "Aaron Watters" 

URL = "http://www.chordate.com/" 

email = "arw@ifu.net" 

from reportlab.lib.units import inch 

pageinfo = "%s/%s/%s" % (Author, email, Title) 

def myFirstPage(canvas, doc): 
    canvas.saveState() 
    #canvas.setStrokeColorRGB(1,0,0) 
    #canvas.setLineWidth(5) 
    #canvas.line(66,72,66,PAGE_HEIGHT-72) 
    canvas.setFont('Times-Bold',16) 
    canvas.drawString(108, PAGE_HEIGHT-108, Title) 
    canvas.setFont('Times-Roman',9) 
    canvas.drawString(inch, 0.75 * inch, "First Page/%s" % pageinfo) 
    canvas.restoreState() 

def myLaterPages(canvas, doc): 
    #canvas.drawImage("snkanim.gif", 36, 36)

    #canvas.setLineWidth(5) 
    #canvas.line(66,72,66,PAGE_HEIGHT-72) 
    canvas.setFont('Times-Roman',9) 
    canvas.drawString(inch, 0.75 * inch, "Page %d %s" % (doc.page, pageinfo)) 
    canvas.restoreState() 

def go(): 
    Elements.insert(0,Spacer(0,inch)) 
    doc = SimpleDocTemplate('ss.pdf') 
    doc.build(Elements,onFirstPage=myFirstPage, onLaterPages=myLaterPages) 

Elements = [] 

HeaderStyle = styles["Heading1"] # XXXX 

def header(txt, style=HeaderStyle, klass=Paragraph, sep=0.3): 
    s = Spacer(0.2*inch, sep*inch) 
    Elements.append(s) 
    para = klass(txt, style) 
    Elements.append(para) 

ParaStyle = styles["Normal"] 

def p(txt): 
    return header(txt, style=ParaStyle, sep=0.1) 

def open_excel(file= 'exc.xls'): 
    try: 
     data = xlrd.open_workbook(file) 
     return data 
    except Exception,e: 
     print str(e) 

#pre = p # XXX 

PreStyle = styles["Code"] 

def pre(txt): 
    s = Spacer(0.1*inch, 0.1*inch) 
    Elements.append(s) 
    p = Preformatted(txt, PreStyle) 
    Elements.append(p) 
p("""\ 
Relational databases manipulate and store persistent 
table structures called relations, such as the following 
three tables""") 

fp = open("/pdf-ex/downloadwin7.png","rb") 
img = Image.open(fp) 
img.show() 
# HACK 
Elements.append(PageBreak()) 


go()

네임 스페이스가 충돌했습니다. import 문 중 하나는 어떤 클래스가 Image 인 PIL.Image (클래스가 아닌 모듈)입니다. 나중에 코드에서 다음 대신

...

from PIL import Image 

시도 ...

import PIL.Image 

...

fp = open("/pdf-ex/downloadwin7.png","rb") 
img = PIL.Image.open(fp) 
img.show() 

수입의 많은 작업, 네임 스페이스 충돌에주의하십시오. 저는 일반적으로 from some_module import * 진술을 매우 조심합니다.

프로젝트와 즐거운 코딩에 대해 감사드립니다.
