Installation

Add this line to your application's Gemfile:

gem 'screenshot_capture'

And then execute:

$ bundle

Or install it yourself as:

$ gem install screenshot_capture

Configuration

Before using the screenshotlayer API client you have to setup your account and obtain your API Access Key.
You can get it by signing up at https://screenshotlayer.com/product.

API Overview

All endpoints in the public API is available through this library.

capture

Usage

The general API is documented here: https://pdflayer.com/documentation.
You can find parameters, result set definitions and status codes documented here as well.

In the examples directory you can find demos and samples of general usage of all the API functions.

Setup

@client = ScreenshotLayer::Client.new( [access_key], [secret_keyword] )

Required Parameters

access_key

Your unique key that you can find on the dashboard of your account under the screenshotlayer account.

secret_key

A userdefined private key that you can find on the dashboard of your account under the screenshotlayer account, it's used to encrypt parameters to prevent unauthorised usage of your account.

Optional Parameters

Secure (only available for Basic, Pro and Enterprise accounts)

Boolean value to indicate if the calls to the API should use a secure protocol or insecure (HTTP/HTTPS). Defaults to false (HTTP, insecure).

Convert (simple case)

Takes a URL and returns the captured image.

Define Query

Second we define an options object. All the options are documented here: https://screenshotlayer.com/documentation

options = ScreenshotLayer::CaptureOptions.new()

Call Client

We then place the actual call to the API, passing in the URL we wish to capture as PDF and the options we defined above.

response = @client.capture(url, options)

Response

[The binary content of the image file] (Defaults to PNG)

Capture (w. filename)

Takes a URL, saves the image to a local file defined by the export argument and returns a response object.

Define Query

We define an options object, and sets the filename option. This option is specific to the RubyGem and not documented in the API found on screenshotlayer. If the directory doesn't exist, it will be created.

options = ScreenshotLayer::CaptureOptions.new()
options.filename = '[local_file_system]/some_directory]/my_file.png'

Simple Request (using Callback)

response = @client.capture(url, options)

Response

{
    "success": true,
    "info": "The image has been saved to your local file system",
    "file_name": "path_to_local_file.png"
}

Example Application

In the [rootdir]/example directory there is a fully functional application which runs all requests against all the endpoints in the API, the examples above can be seen there as source code.

The example application uses a process.env variable to hold the access key.

Tests

The tests are written using the rspec testing library.
RSpec http://rspec.info/

In order to run the tests, the following environment variables needs to be set:

ACCESS_KEY = [access_key]
SECRET_KEYWORD = [secret_keyword]
EXPORT_FTP = [path_to_ftp_account]
