Introduction

The following tutorial shows you how to convert PDF files to HTML or SVG using a hosted BuildVu cloud API, such as:

Whilst all the above services can be accessed with plain old HTTP requests, this tutorial uses our open source Ruby IDRCloudClient which provides a simple Ruby wrapper around the REST API.

Prerequisites

There are two approaches to using the IDRCloudClient in your project.

Using gem, install the idr_cloud_client gem with the following command:

gem install idr_cloud_client

Alternatively, you can add the line “gem ‘idr_cloud_client’” to your applications gemfile then run the following command.

bundle install

Code Example

Here is a basic code example to convert PDF files to HTML or SVG. Configuration options and advanced features can be found below.

require 'idr_cloud_client'

client = IDRCloudCLient.new('http://exampleURL.com/' + IDRCloudCLient::BUILDVU)

result = client.convert(
    # token='Token', # Required only when connecting to the IDRsolutions trial or cloud subscription servers
    input: IDRCloudCLient::UPLOAD, 
    file: 'path/to/exampleFile.pdf')

client.download_result(result, 'path/to/output/dir')

puts 'Download URL: ' + result['downloadUrl']

Configuration Options

The BuildVu API accepts a stringified JSON object containing key value pair configuration options to customise your conversion. The settings should be provided to the convert method. A full list of the configuration options to convert PDF files to HTML or SVG can be found here.

settings:'{"key":"value","key":"value"}'

Upload by URL

As well as uploading a local file you can also provide a URL which the BuildVu Microservice will download and then perform the conversion. To do this you should replace the input and file values in the convert method with the following.

input:IDRCloudClient.DOWNLOAD
url:'http://exampleURL/exampleFile.pdf'

Using Authentication

If the BuildVu Microservice requires authentication, you will need to provide a username and password. These are provided by passing a variable named auth to the convert method as shown below.

auth:('username', 'password'))
