background image using report lab?

问题 how can i add background image to pdf pages using reportlab? 回答1: Assuming you have PIL (Python Imaging Library) installed, you can use canvas.drawImage . To make a background image, just call drawImage before anything else on the page and it will be drawn first: then everything else will draw on top of it. You can find out more about this function on page 15 of the ReportLab Manual. 来源： https://stackoverflow.com/questions/5138301/background-image-using-report-lab

问题 I am a newbie to python. I have to create an ordered list in my pdf document using Reportlab . I found these two classes ListFlowable(), ListItem() in the user-guide of Reportlab to do the same.

I am using python 2.6, reportlab 2.5. 回答1: In my install of

How to add a link to the word using reportlab?

由 此生再无相见时 提交于 2019-12-10 10:54:24
问题 I am confused with the links and reportlab. I would like to have a text with a word, which 'contains' a clickable link. For example, I write such text: This web-site is called StackOverflow. And I want the word StackOverflow to be clickable and to lead to the corresponding page. Is there any way to achieve that? UPDATE In this case I want to add the hyperlink to the word, not just to the canvas. 回答1: So, super great thanks to Steven Byrne, who suggested the solution by Jerry Stratton <- to

问题 I need to generate PDF document using the Bottle framework. I tried similar to Django but that didn't work: @bottle.route('/pd') def create_pdf(): response.headers['Content-Type'] = 'application/pdf; charset=UTF-8' response.headers['Content-Disposition'] = 'attachment; filename="test.pdf"' from io import BytesIO buffer = BytesIO() from reportlab.pdfgen import canvas p = canvas.Canvas(buffer) p.drawString(100,100,'Hello World') p.showPage() p.save() pdf = buffer.getvalue() buffer.close()

Django, ReportLab PDF Generation attached to an email

由 蹲街弑〆低调 提交于 2019-12-09 06:12:45
问题 What's the best way to use Django and ReportLab to generate PDFs and attach them to an email message? I'm using a SimpleDocTemplate and can attach the generated PDF to my HttpResponse - which is great, but I'm having trouble finding out how to exactly add that same attachment to an email: # Create the HttpResponse object with the appropriate PDF headers. response = HttpResponse(mimetype='application/pdf') response['Content-Disposition'] = 'attachment; filename=invoice.pdf' doc =

Splitting ReportLab table across PDF page (side by side)?

由 三世轮回 提交于 2019-12-08 19:28:28
The code below creates a nice test table with 99 rows of data and a header that gets repeated at each page break. The table is quite narrow so I am trying to figure out how to make it split so that it has rows 1-37 on the left hand side of the first page, rows 38-74 on the right hand side of the first page, and rows 75-99 on the left hand side of the second page. I've called this "splitting a table across a page" but there may be a better name for what I am trying to do so I hope I have described it accurately. from reportlab.platypus import SimpleDocTemplate, Table, TableStyle, Paragraph,

Python ReportLab use of splitfirst/splitlast

由 十年热恋 提交于 2019-12-08 19:28:20
问题 I'm trying to use Python with ReportLab 2.2 to create a PDF report. According to the user guide, Special TableStyle Indeces [sic] In any style command the first row index may be set to one of the special strings 'splitlast' or 'splitfirst' to indicate that the style should be used only for the last row of a split table, or the first row of a continuation. This allows splitting tables with nicer effects around the split. I've tried using several style elements, including: ('TEXTCOLOR', (0,

Use QrCodeWidget (or PlotArea) with platypus

由 天涯浪子 提交于 2019-12-08 14:09:30
My django app is using a multi-frames reportlab pdf report in witch I would like to add some barcodes/qr-codes. The problem I have is that every object I add to my layout have to be a Flowable. So the question would be as to cast a PlotArea (mother class of QrCodeWidget) as Flowable. If we have an answer here the error message we can get if we add the QrCodeWidget as AttributeError: QrCodeWidget instance has no attribute 'getKeepWithNext' Ok, I made my own Flowable, it was simpler than I taught. It's as simple as doing it on a canva with this API. from reportlab.platypus import Flowable from

Generating a pdf of long tables with reportlab

由 牧云@^-^@ 提交于 2019-12-08 09:48:04
问题 I am dealing with generating a PDF from a huge data list. There is no fancy styling or formatting involved. It's just that the data is a huge list (about 500 rows and 500 columns). Here is my code. Currently it will have no problem splitting rows across multiple pages depending on the page size, but the columns are being cut off since 500 columns don't fit in one page. I would also like to split columns across different pages as well. Each cell entry is just an integer. How can I achieve that
