This PDF is split in one page PDFs (using pdftk) and converted to SVG using InkScape. Input for this package is a PDF file containing some figures and tables and a directory containing JSON files with their locations (page number, bounding box in the page). Pdftoolkit ( ), both available for Windows, Mac and Linux systems. InkScape (version 0.91, tested on Ubuntu and version 0.47, Mar 4 2015, tested on RedHat) and 2. System dependencies for this repository are: 1. While the parsers are fairly generic, I have only tested them on SVGs produced by InkScape, hence the name. Scala offers excellent libraries for writing parser combinators (one of the reasons it is heavily used in DSLs). The bounding box calculation takes all transform operations (including the ones coming from groups) into consideration.įor more details about the data models, see models directories in pathparser, textparser and rasterparser packages. The hierarchical tree structure is flattened first for each path, character and image we find out the groups it belongs to.Įach text path in the SVG is then converted into a stream of character objects with bounding box and font information, which is inferred from the font.Įach graphics path is converted into an object with a sequence of path commands, sequence of transformation matrices and a bounding box. This repository contains parser combinators (SVG operations follow EBNF syntax) that take an InkScape SVG and convert each graphics path, text path and image to an object. SVG standard doesn't provide such bounding boxes they must be calculated. For most purposes, we need the bounding boxes for the paths, characters and images embedded in the PDF. This is a fairly complicated hierarchical representation, as commonly found in most XML files. SVG produced by InkScape contains many information such as grouping elements, multiple transformation operations such as "rotate", "scale" etc. This SVG is produced by InkScape by converting a page of a PDF (see this for an example). This repository contains Scala code for generating such a representation from PDFs. PDF doesn't have a flat object oriented representation making it extremely hard to process. PDF and SVG are both vector graphics, with considerable differences.
