BinaryTransformer
Interface and executor for a transformers to transform byte arrays in a pipeline-based design programmatically in ruby.
This can be used to parse text blobs, resize image, compress music, encode video... etc
Currently, these binaries are available:
- NONE
Installation
Add this line to your application's Gemfile:
gem 'binary_transformer'
And then execute:
$ bundle
Or install it yourself as:
$ gem install binary_transformer
Usage
Using transformers
Assuming you have a few image transformers
ImageCompressor
that compress images,
ImageResizer
that resizes images,
Sepia
that converts image to sepia,
and Blur
that blurs the image
which all implements
the BinaryTransformer::Transformer
interface, the usage is as follows:
# Transformer instances
compressor = ImageCompressor.new
resize = ImageResizer.new
sepia = SepiaTransformer.new
blur = BlurTransformer.new
# Obtain Binary
binary IO.binread "image.png"
# Extend the binary
binary.extend StreamLike
# Pipe the binary through the transformers. Use >> to chain and > for the last transformer
converted = binary >> compressor >> resize >> sepia > blur
# Write the binary back
IO.binwrite "converted.png", converted
Development
After cloning, run to install dependencies
$ bundle install
To run unit tests:
$ bundle exec rspec
