pagebot 1.0.3

Scripted page layout framework for Python.

What is PageBot?

PageBot® is a scriptable page layout, vector graphics and typography environment that enables designers to create high quality documents in various print-ready and web-based formats. It is available as a Python library with multi-platform support based on Flat and as a Mac OS X extension that uses DrawBot.

PageBot consists of three abstraction levels:

• Builders, the libraries and formats PageBot usesto generate the final result, for example DrawBot, Flat and markup languages.
• Contexts that provide a fixed API for the builders.
• Documents, Views and Elements, our format independent classes.

The official PageBot documentation can be found at pagebot.io.

Installation

Pagebot runs on Python 3. We recommend updating to version 3.7 / 3.8.

Usage

from pagebot.document import Document
from pagebot.elements import newRect
from pagebot.conditions import Center2Center, Middle2Middle
from pagebot.toolbox.units import pt
from pagebot.toolbox.color import color

W, H = pt(500, 400)
doc = Document(w=W, h=H, autoPages=1)
page = doc[1]

# Create a new rectangle element with position conditions
newRect(parent=page, fill=color('red'), size=pt(240, 140),
    # Show measure lines on the element.
    showDimensions=True, 
    conditions=[Center2Center(), Middle2Middle()])
# Make the page apply all conditions.
page.solve() 
# Export the document page as png, so it shows as web image.
doc.export('_export/RedSquare.png')

Feature Description

Current Functionality

Current features include:

• Various types of Element objects can be placed on a page or inside other Element objects.
• Grids can be defined through style measurements and views.
• Page templates (or templates for any other element combination) can be defined and applied.
• Automatic layout conditions for elements, for example even distribution across or floating down parent elements.
• Specialized views on a Document, such as plain pages, spreads and other layout of page groups, optional with crop-marks, registration-mark, color-strips, file name, etc. The result of all views can be placed on pages as illustration.
• Graphics - using all Drawbot drawing tools.
• All image filtering supplied by Drawbot ImageObject.
• Cascading styles, where Element values inherit from parent Elements, similar to CSS behavior.
• Text flows are using the macOS FormattedString for all typographic parameters.
• Random Text generator for headlines and articles.
• Read text from MarkDown and XML (.MD .XML)
• Support large amount of text processing functions:
  • centered, left, right and justified
  • Text to fit a box and elastic box to fit text
  • Tabular setting

  • Variable Font UI access and instance creation based on fontTools
  • Access to font metrics.
  • Outline Font access modification.
  • Space, groups and kerning access and modifcation.
  • OT layout and feature access and modification.
• 3D Positioning of points, for future usage.
• Motion Graphics, export as animated .gif and .mov files, keyframing timeline,
• Export to PDF, PNG, JPG, SVG, (animated) GIF, MOV, XML, through programmable views.
• Build web sites, pre-compiling all images used into the formats that can be displayed by browsers (.PNG .JPG .SVG)
• Automatic table of contents, image references, quote references, etc. from composed documents.

Unit Testing

PageBot uses Python's native doctest library to perform unit tests:

• https://docs.python.org/2/library/doctest.html

Note: doctest can be run in Sublime with cmd-B

Future Developments

• Element classes supporting various types of graphs, info-graphics, maps, PageBot document layout, Variable Font axes layout, font metrics.
• Font class supporting CFF (.otf) and UFO.
• Views for thumbnail page overview, combined booklet-sheets for print, site-maps, etc.
• Add export of text to MarkDown .md files.
• Add export to online documents, such as HTML/CSS/JS for specific designs of web pages, such as Kirby.
• Export to WordPress® PHP sites.
• Export to Ruby®/Sketchup® data files.
• Add export to Angular® files.
• Export to InDesign® and Illustrator®, as close as possible translating PageBot elements to the native file format of these applications.
• Time line, definition and editing, length and fps.
• Integrate the PageBot manual builder with other export functions of the library.
• Add more unit-tests to guarantee the integrity of the library and output consistency.
• Automatic support of ornament frames, in connection to the Element borders and the layout of exiting (TN) border fonts.
