问题 I'm using the on page function and a page template to make headers for a subset of the pages in my document: templates.append(PageTemplate(id='Overview', frames=frame, onPage=HeaderOverview)) The header function for this template: ################################ # Function HeaderOverview - header for overview page def HeaderOverview(canvas,doc): canvas.saveState() headboxh = 15 headboxx = 20 headboxy = 730 headboxw = 570 canvas.rect(headboxx, headboxy, headboxw, headboxh, fill=1) canvas

问题 My main goal is to have all the Image flowables on a page to act as though they are clickable links. In order to do this, I would create a canvas.linkRect() and place it over the rendered Image. Here's an example of how I use canvas.linkRect(): canvas.linkURL( url='url_goes_here', rect=(x1, y1, x2, y2), #(x1, y1) is the bottom left coordinate of the rectangle, (x2, y2) is the top right thickness=0, relative=1 ) After looking in the BaseDocTemplate class, I found a method called afterFlowable

问题 TL;DR: Is there some way of telling ReportLab to use a specific font, and fallback to another if glyphs for some characters are missing? Alternatively, Do you know of a condensed TrueType font which contains the glyphs for all European languages, Hebrew, Russian, Chinese, Japanese and Arabic? I've been creating reports with ReportLab, and have encountered problems with rendering strings containing Chinese characters. The font I've been using is DejaVu Sans Condensed, which does not contain

问题 How can I create a bulleted list in ReportLab? The documentation is frustratingly vague. I am trying: text = ur ''' <para bulletText="•"> item 1 </para> <para bulletText="•"> item 2 </para> ''' Story.append(Paragraph(text,TEXT_STYLE)) But I keep getting errors like list index out of range . It seems that I can't put more than one <para></para> in a single call to Paragraph() ? I also tried setting TEXT_STYLE.bulletText="•" but that doesn't work either... 回答1: The bulletText argument is

问题 I'm trying to add a simple "page x of y" to a report made with ReportLab.. I found this old post about it, but maybe six years later something more straightforward has emerged? ^^; I found this recipe too, but when I use it, the resulting PDF is missing the images.. 回答1: I was able to implement the NumberedCanvas approach from ActiveState. It was very easy to do and did not change much of my existing code. All I had to do was add that NumberedCanvas class and add the canvasmaker attribute

问题 I use a table but, I draw in in a canvas to control the position of the flowables, this because I have a template in a pdf, an I merge with pyPDF. The wrap is done in a table but the text go up, not down that's what I hope. c is the canvas Code from reportlab.pdfgen import canvas from reportlab.lib.pagesizes import A4 from reportlab.lib.styles import getSampleStyleSheet from reportlab.platypus import Paragraph, Table from reportlab.lib.units cm width, height = A4 styles = getSampleStyleSheet(

问题 I want to embed matplotlib charts into PDFs generated by ReportLab directly - i.e. not saving as a PNG first and then embedding the PNG into the PDF (i think I'll get better quality output). Does anyone know if there's a matplotlib flowable for ReportLab? Thanks 回答1: Here's a solution using pdfrw: #!/usr/bin/env python # encoding: utf-8 """matplotlib_example.py An simple example of how to insert matplotlib generated figures into a ReportLab platypus document. """ import matplotlib matplotlib

问题 I use reportlab rml(report markup language) to generate pdf by rml2pdf, which comes with a default footer content, so, how to remove the footer of the pdf? (I can't find the specific solutions in the official document ) . 回答1: You may have to write your own stylesheet for footer , with that stylesheet you can overwrite your footer you may have two <pageGraphics> sections inside a <pageTemplate> . The way this is interperted by RML2PDF is that the first one is carried out before the contents
