ParagraphStyle is used to set our paragraph's text alignment in this example, but it can do much more than that see page 67 of the user guide. Finally, the inch is a unit of measurement to help in positioning items on your PDF.
This means that the logo will be two inches from the top and two inches from the left. I don't recall the reason why Reportlab's examples use a Story list, but that's how we'll do it here as well. Basically you create a line of text, a table, and image or whatever and append it to the Story list. You'll see that throughout the entire example. The first time we use it is when we add the image. Before we look at the next instance, we'll need to look at how we add a style to our styles object:.
The reason this is important is because you can use the style list to apply various paragraph alignment settings and more to text in your document.
In the code above, we create a ParagraphStyle called "Justify". All it does is justify our text. You'll see an example of this later in the text.
For now, let's look at a quick example:. For our first line of text, we use the Paragraph class. In this instance, we set the font's point size to 12 and use the normal style which is left aligned, among other things. The rest of the example is pretty much the same, just with Spacers thrown in here and there. At the end, we call doc. We didn't even scratch the surface of what all you can do with Reportlab though.
Some examples include tables, graphs, paginating, color overprinting, hyperlinks, graphics and much more. I highly recommend that you download the module along with its user guide and give it a try! Search for:. Cross-Platform Python. Want to learn more about working with PDFs in Python?
For the newer Reportlab 3. Let's see how the canvas object works: from reportlab. Canvas "hello. All you need to do is the following: from reportlab. Canvas 'myfile. Now let's do something a little more complicated and useful.
See how to pull a range of financial data from a Django application to produce a report, including complex tables and custom data graphics. Learn how ReportLab can dynamically display data the way you want it to, and get a taste for the almost limitless design options possible. This example shows how to take JSON data and use it to create up-to-date fund fact sheets.
Learn how text, data and graphs can be easily included and the powerful layout options ReportLab gives. Welcome to the new ReportLab tutorial. Here you can get a basic introduction to a common application architecture and start experimenting with some fundamental ReportLab technologies.

Once these are completed, you're ready to go. First thing's first: download our tutorial pack. This includes a number of images which you will need later. Notice that your 'checklist' is broken; that's ok for now, we'll come back to that later. Let's take a look at the flyer PDF.
The data is coming from the XML file, products. A standard technique is to build up Python objects with the variable data of interest and pass it to our templating system, preppy. We'll look at this process later, but for now, let's dive right in and get the document looking right. Let's take a quick tour before making changes. This allows you to import functions and call on data objects which have been passed in. They can include frames to handle flowing text, as well as static components of the page, such as images, text, and graphics.
Later on, as we pass in our content, we can choose which templates to use for each page. You've put in all the hard effort of defining styles, frames, and fonts, and now it's time to give your document some content. We're looping over all our products and printing a paragraph for each product's name. Let's add product summary and product price as well; your story should now look like this:.
You should see output like shown below, with new facts about each product displayed:. We have more content, but the appearance is still not ideal. Let's see how we can use a page template to arrange our content. Go back to templates and take note of each part:. By default, the PDF rendering engine uses the first template until it is told otherwise, so in this case, 'blank' has been used on all pages.
Notice that a nice PDF background has been used on which the products list is printed. That can also be used to include full static pages. Let's use pre-made PDFs to replace the blank first page and insert a standard end page. Your story should look like this:. Ideally, we would be able to keep the descriptions from breaking across pages, so that all the information about a product stayed together. Your stylesheet should now look like this:. Finally, let's get our colors and fonts correct.
We can register a new font and a new color in the docinit section; edit yours to look like this:. And there you have it, a professionally finished document created on the fly from an XML file.
