Dynamically generated PDF files working in most readers except Adobe Reader

China☆狼群 提交于 2019-12-06 12:35:21
I'm trying to dynamically generate PDFs from user input, where I basically print the user input and overlay it on an existing PDF that I did not create. It works, with one major exception.

So I thought I'd trace the path of me creating the files - 1 - Original PDF of background PDF 1.2 made with Adobe Distiller with the LZW encoding.

How to add a link to the word using reportlab?

我只是一个虾纸丫 提交于 2019-12-06 05:33:29
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.

How to know on what page number flowable was placed during rendering a pdf with reportlab

But how can i determine on what page it will be placed? What is the best way to achieve this? At what point do you need this information? It becomes available as the document is constructed, so you can get it after rendering by overriding methods such as afterPage , afterDrawPage , and afterFlowable . You can then get the page number from the DocTemplate class (I believe there's a class variable called
