问题 I am wondering how I can make my script save to the Desktop. Here's my code: from reportlab.pdfgen import canvas from reportlab.lib.pagesizes import letter from reportlab.platypus import Image import csv import os data_file = "hata.csv" def import_data(data_file): inv_data = csv.reader(open(data_file, "r")) for row in inv_data: var1 = row[0] # do more stuff pdf_file = os.path.abspath("~/Desktop/%s.pdf" % var1) generate_pdf(variable, pdf_file) def generate_pdf(variable, file_name): c = canvas

问题 I am trying to create a document that has page numbering of the format "Page x of y". I have tried the NumberedCanvas approach (http://code.activestate.com/recipes/576832/ and also from the forums https://groups.google.com/forum/#!topic/reportlab-users/9RJWbrgrklI) but that conflicts with my clickable Table of Contents (https://www.reportlab.com/snippets/13/). I understood from this post http://two.pairlist.net/pipermail/reportlab-users/2002-May/000020.html that it may be possible using forms

问题 I'm trying to create a pdf using Python's reportlab module. I generated a png with matplotlib and saved it in the pdf file using report labs canvas.drawImage method. My problem is that the generated png file is very fuzzy. I specified the size in inches with plt.figure(figsize=(20,10)) and saved the picture with the plt.savefig method. This works out perfectly (except the fuzzy quality of the picture). But when I increase the dpi within the savefig method the size of the picture increases. Is

问题 I'm having difficulty making ReportLab render Chinese Characters. From everything I've looked up people are saying that it is probably a font problem but I've used a lot of different fonts and it doesn't even seem to be using them at all. The Chinese characters always just come out as black squares. Below is some sample code of what I have. # -*- coding: utf8 -*- from reportlab.lib.pagesizes import letter from reportlab.pdfbase.ttfonts import TTFont from io import BytesIO pdfmetrics

问题 I've a got a django app that currently generates pdfs using a canvas that the user can download. I create a StringIO buffer, do some stuff and then send call response.write. # Set up response response = HttpResponse(mimetype='application/pdf') response['Content-Disposition'] = 'attachment; filename=menu-%s.pdf' % str(menu_id) # buffer buff = StringIO() # Create the pdf object p = canvas.Canvas(buff) # Add some elements... then p.showPage() p.save() # Get the pdf from the buffer and return the

问题 I am latest reportlab and django, and standard platypus TOC with the notify to 'TOCEntry' works great for my document. I am now trying to add 2 more sections to Table of Contents: 'List of Figures', and 'List of Tables'. Since the flowables h1, h2, table, image etc. in the document can occur in any order, I cannot seem to separate the 2 lists from the main TOC. Ideally I would like to have something like: Table of Content: Heading1 Sub1 Sub2 Heading2 Sub3 Sub4 Sub5 List of Figures: Figure1

问题 I am coming back with a new question which I am unable to answer, having scratched my head the whole day on it. I want to generate a PDF from a webpage by clicking on a "Download PDF" button. I tried several modules including Reportlab and XHTML2PDF but I am not able to generate any pdf nor downloading it... Here is what I did with Reportlab, following Render HTML to PDF in Django site - - views.py - - import cStringIO as StringIO import ho.pisa as pisa from django.template.loader import get
