问题 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' 回答1: Ok, I made my own Flowable, it was simpler than I

GMAT写作 对于考生在词汇运用方面有较高要求,考生需要写出符合书面语规范的句子,并合理运用各类词汇避免重复。由于写作时间紧张,一些考生在大意之下习惯性地使用了一些简单偏口语化的词汇,无形中降低了文章格调。那么有哪些常见词汇需要避免出现在GRE写作中呢?下面小编就为大家具体介绍。 GMAT写作为何要避免使用常见词汇? GMAT写作评分中关于用词有一个非常具体的评判标准,demonstrates control of language, including diction and syntactic variety,即通过用词用句的变化性有效地体现行文语言的多样性。而许多中国考生被扣分,正是因为用词过于单调重复和口语化。下面给大家举5个最常见的不地道且常被滥用的LOW词。 1. Really Example:The swimmer really performed admirably. “Really”表示“真的”,有强调的作用。但很多时候“really”并没有告诉读者或听者重要、有用的信息,缺乏说服力。如果你想要表达一个事实,不妨尝试去掉“really”,反倒更让信服。比如:The swimmer performed admirably. 2. Things/ Stuff Example: “The article said a lot of things and stuff.”

this is a bit related to this post I am trying to place an image on the background, and I want to be able to write text over it. using canvas.drawImage helps, but that's too low level approach for me. My program uses platypus, but canvas.drawImage is part of different library. I've been able to insert images with platypus.Image , but couldn't figure out how to make it as background. Any advice would be great, Thanks D When you create a page template in Platypus you have the ability to pass a function via the named argument onPage . In that function you can place all your basic page formatting

ReportLab LayoutError: too large on page

I'm doing my first program using ReportLab where I don't know in advance where the page breaks will fall and I'm having trouble. To keep things simple I'm using the SimpleDocTemplate . My flowables look something like this: flowables = [Paragraph("Some title", style=headerParagraphStyle), Spacer(0, 10), Paragraph("first paragraph", style=bodyParagraphStyle), Paragraph("second paragraph", style=bodyParagraphStyle), ... Paragraph("nth paragraph", style=bodyParagraphStyle), PageBreak(), Paragraph("Some title", style=headerParagraphStyle), Spacer(0, 10), Paragraph("first paragraph", style

Is it possible to get a Flowable's coordinate position once it's rendered using ReportLab.platypus?

风格不统一 提交于 2019-11-30 14:19:13
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(self, flowable). I overrode that method and called dir() on the flowable passed in, resulting in this:
