pdf.cr

A crystal PDF library in very early stages of development.

The immediate goal is to generate PDF files, possibly similar to the ruby gem prawn.

Installation

1. Add the dependency to your shard.yml:

dependencies:
  pdf:
    github: oneiros/pdf.cr

2. Run shards install

Usage

require "pdf"

Document Creation DSL

include PDF::DSL

my_pdf = document do
  page_size A4
  page_orientation Orientation::Landscape

  page do
    text "Headline", at: {0, 10}
    line from: {0, 0}, to: {10, 10}
  end

  page do
    circle at: {100, 100}, radius: 20
  end
end

my_pdf.write_to_file("/tmp/my.pdf")

Low-level primitives

The classes in src/pdf/core/ provide a very low-level abstraction, trying to preserve naming used in the PDF spec.

src/pdf/core/primitives/ holds classes that represent "objects", the basic building blocks of a PDF file.

Development

TODO: Write development instructions here
