gastly's Introduction

👻 Gastly

Create screenshots or previews of web pages using Gastly. Under the hood Phantom.js and MiniMagick.

Gastly, I choose you!

Installation

Add this line to your application's Gemfile:

gem 'gastly'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gastly

Usage

Gastly.capture('http://google.com', 'output.png')

It's also possible to further customize the creation of screenshots and further processing of the resulting image:

screenshot = Gastly.screenshot('http://google.com')
screenshot.selector = '#hplogo' # By default, the full screen is captured
screenshot.browser_width = 1280 # Default: 1440px
screenshot.browser_height = 780 # Default: 900px
screenshot.timeout = 1000 # Default: 0 seconds
screenshot.cookies = { user_id: 1, auth_token: 'abcd' } # If you need
screenshot.proxy_host = '10.10.10.1' # If you want to use a http proxy
screenshot.proxy_port = '8080'
screenshot.phantomjs_options = '--ignore-ssl-errors=true'
image = screenshot.capture

screenshot = Gastly.screenshot('http://google.com', selector: '#hplogo', timeout: 1000)
image = screenshot.capture

You can resize, crop or change the format of the screenshot:

image = screenshot.capture
image.crop(width: 250, height: 250, x: 10, y: 0) # Crop with an offset
image.resize(width: 110, height: 110) # Creates a preview of the web page
image.format('png')
image.save('output.png')

Development

After checking out the repo, run bin/setup to install dependencies. Then, 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 version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

gastly's Issues

Some parts of the screenshot are missing

Hi,

While using Gastly to take screenshots in some websites, the screenshot is missing the header and footer.

Can you please tell the solution?

Font errors while taking screenshot

This is happening on Alpine 14 (Docker) with Rails 6.1 and PhantomJS 2.1.1.

Had to remove the PhantomJS installation the gem did because whenever I was trying to run PhantomJS it was throwing File or directory not found (the binary was there ofc) so I figured it's a compatibility thing with the OS.

After installing PhantomJS as per https://github.com/Overbryd/docker-phantomjs-alpine/releases it started working but trying to take screenshots throws errors below (also reinstalled fontconfig and fontconfig-dev)

Any suggestions?

PS Looks like PhantomJS is getting canned, any alternatives?

Not working on some sites

I got errors for some sites, for example:

Not working with dynamic urls

Hi,

I'm trying to generate an image from a dynamic url which comes in parameters
Parameters: {"share_url"=>"http://localhost:3000//share?id=Ym1jLTk0"}
and in my code am doing Gastly.capture(params[:share_url], "destination.png")

But its taking lot of time. When I try the same in rails console, its generating image in couple of seconds.

Could you please tell me the solution?
