How to install Gyazo on Ubuntu

[Peter L]

Gyazo is a screenshot-taker that takes a screenshot of a custom area. It is only made for Windows, but can be coded for Ubuntu to. Here is what you do:

1. Install Imagemagick in the Software Center


2. Open the Terminal and type "sudo apt-get install ruby" without the quotes. Let it install.


3. Now open gedit and paste this code in:

Code:

#!/usr/bin/env ruby

# setting
browser_cmd = 'firefox'
clipboard_cmd = 'xclip'
proxy_addr = nil
proxy_port = nil

require 'net/http'

# get id
idfile = ENV['HOME'] + "/.gyazo.id"

id = ''
if File.exist?(idfile) then
  id = File.read(idfile).chomp
end

# capture png file
tmpfile = "/tmp/image_upload#{$$}.png"
imagefile = ARGV[0]

if imagefile && File.exist?(imagefile) then
  system "convert #{imagefile} #{tmpfile}"
else
  system "import #{tmpfile}"
end

if !File.exist?(tmpfile) then
  exit
end

imagedata = File.read(tmpfile)
File.delete(tmpfile)

# upload
boundary = '----BOUNDARYBOUNDARY----'

HOST = 'gyazo.com'
CGI = '/upload.cgi'
UA   = 'Gyazo/1.0'

data = <<EOF
--#{boundary}\r
content-disposition: form-data; name="id"\r
\r
#{id}\r
--#{boundary}\r
content-disposition: form-data; name="imagedata"; filename="gyazo.com"\r
\r
#{imagedata}\r
--#{boundary}--\r
EOF

header ={
  'Content-Length' => data.length.to_s,
  'Content-type' => "multipart/form-data; boundary=#{boundary}",
  'User-Agent' => UA
}

Net::HTTP::Proxy(proxy_addr, proxy_port).start(HOST,80) {|http|
  res = http.post(CGI,data,header)
  url = res.response.to_ary[1]
  puts url
  if system "which #{clipboard_cmd} >/dev/null 2>&1" then
    system "echo -n #{url} | #{clipboard_cmd}"
  end
  system "#{browser_cmd} #{url}"

  # save id
  newid = res.response['X-Gyazo-Id']
  if newid and newid != "" then
    if !File.exist?(File.dirname(idfile)) then
      Dir.mkdir(File.dirname(idfile))
    end
    if File.exist?(idfile) then
      File.rename(idfile, idfile+Time.new.strftime("_%Y%m%d%H%M%S.bak"))
    end
    File.open(idfile,"w").print(newid)
  end
}

The line that says browser_cmd = 'firefox' will open Firefox so if you want it to open Chromium instead replace it with browser_cmd = 'chromium-browser'

Now save it as gyazo.rb

4. Right-click gyazo.rb and click Properties. And under Permissions check the Execution box.


5. Drag it to your navbar on the top and when you want to take a picture just click it!


Enjoy!

I actually find less of a need for a screenshot program in Linux lol. With the print screen method you don't even have to copy the image into paint or photoshop, it will give you a window with options to save it right away.

Unless you want to edit the image afterwards, then there may be a problem, but if they had a function that would allow you to do some cropping and box creating from the print screen button, that would be genius...

I do find it useful, it depends on the situation. I like how it saves automatically, but sometimes I only want a portion really quick.

Can you tell me how to use that method?

Is it that -scrot thing you type into a terminal?

[Peter L]

Rootz it should happen automatically.

yeah, I just press my Print screen button and it will come up with the option to save it automatically within the first couple seconds of pressing the button on my keyboard lol.
