Simple wrapper for the Ghostscript command – it's assumed that you have the
gs command installed.
Note: This was developed against version 9.20 of the Ghostscript command and is a work-in-progress. No doubt there are some issues (perhaps even major ones – namespacing, for instance?).
For more detailed documentation, take a look at the source docs – http://www.rubydoc.info/github/lshepstone/gs-ruby
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install gs-ruby
Typical usage might look like:
GS.run('input.ps', GS::OUTPUT_FILE => 'output.pdf')
Or using a block to work with the command before it's run:
GS.run('input.ps') do |command| command.option(GS::OUTPUT_FILE, 'output.pdf') end
Global configuration is possible:
GS.configure do |config| # ... end
By default all output is logged to
$stdout, but the logger can be configured:
# For a single command instance. GS.run('input.ps') do |command| # command.logger = end # For all command instances. GS.configure do |config| # config.logger = end
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake spec to run the tests. You can also run
bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run
bundle exec rake install. To release a new version, update the version number in
