Installation

This program must be compiled from source.

Prerequisites:

• A working Crystal compiler is needed.
• The tesseract binary must be available in your PATH.

1. Clone this git repo:

$ git clone git@github.com:garethrees/image_to_html.git

1. To build a binary:

$ make bin/image-to-html

1. To use as a library, add the dependency to your shard.yml:

Usage

As a binary:

# Print the HTML to stdout
$ bin/image-to-html /path/to/image.jpg

# You can redirect stdout to create a HTML file
$ bin/image-to-html /path/to/image.jpg > image.jpg.html

As a library:

# Just generate the HTML
html = ImageToHtml.run("/path/to/image.jpg")

# Or build it up yourself
