How to set the bullet size in a python reportLab nested list

To set the bullet size in a Python ReportLab nested list, you can use the listStyle parameter and the bulletFontSize attribute of the ListStyle class.

Here’s an example:

python
from reportlab.lib.styles import ListStyle from reportlab.lib.enums import ListType from reportlab.lib import colors from reportlab.pdfgen import canvas from reportlab.platypus import SimpleDocTemplate, ListFlowable, ListItem # Define the list style bullet_size = 10 # Change the value to the desired bullet size list_style = ListStyle( 'bullet', leftIndent=bullet_size*2, bulletFontSize=bullet_size, bulletColor=colors.black ) # Define the nested list nested_list = [ 'Item 1', ['Subitem 1', 'Subitem 2'], 'Item 2', ['Subitem 1', 'Subitem 2'] ] # Create the flowable list flowable_list = ListFlowable( [ ListItem(item, listStyle=list_style) if isinstance(item, list) else ListItem(item) for item in nested_list ], bulletType='bullet', start='bullet', leftIndent=bullet_size ) # Create the PDF document pdf_doc = SimpleDocTemplate('nested_list.pdf') pdf_doc.build([flowable_list])

In this example, the ListStyle object is defined with the desired bulletFontSize attribute, and then passed as a parameter to each ListItem in the nested list. The ListFlowable object is then created with the bulletType and start parameters set to 'bullet' to use the bullet symbol, and the leftIndent parameter set to the desired bullet size multiplied by two, as recommended in the ReportLab documentation. Finally, the ListFlowable is added to the PDF document using the build method.

What are the sizes in ReportLab?

ReportLab is a Python library for creating PDF documents. In ReportLab, there are several sizes that can be used to define the dimensions of the pages and elements in a PDF document.

  1. A0, A1, A2, A3, A4, A5, A6: These are standard ISO paper sizes commonly used in Europe and other parts of the world. A4 is the most commonly used size for printing documents.

  2. Letter, Legal: These are standard paper sizes commonly used in the United States.

  3. BANNER: A custom size for creating banners.

  4. CUSTOM: This allows you to define your own custom size by specifying the width and height in points.

In addition to these sizes, there are also several constants that can be used to specify the orientation of a page or element, including PORTRAIT (vertical) and LANDSCAPE (horizontal).

What is ReportLab in Python?

ReportLab is a powerful open-source library for generating PDF documents in Python. It provides a high-level API for creating complex and dynamic PDF documents, including features like text flow, tables, charts, and graphics.

ReportLab was originally developed in the late 1990s as a commercial product for generating PDF reports from databases, but in 2001 it was released as an open-source project under the BSD license. Since then, it has become a popular choice for generating PDFs in Python, particularly for web applications.

With ReportLab, you can create PDF documents programmatically, using a combination of Python code and declarative markup. The library includes a range of built-in tools for handling common PDF tasks, such as font management, color spaces, and page layouts. It also includes support for advanced features like vector graphics, annotations, and encryption.

Overall, ReportLab is a versatile and powerful library that provides developers with a lot of flexibility and control over PDF generation in Python.
