Poleica

_ -> PDF -> Image

Image -> Image

Basically it just takes some files, tries to convert it to PDF or PNG. It was modularly written, so you can improve the gem with more conversion tools (html to pdf is planned).

Ubuntu :

Look at .travis.yml file

MacOS :

brew install ghostscript graphicsmagick

Download LibreOffice and install it.

Then :

gem install poleica

or in Gemfile :

gem 'poleica'

Poleica.new(file_path).to_png
Poleica.new(file_path).to_pdf
Poleica.new(file_path).to_thumbnail
Poleica.new(file_path).to_png(width: 400, weight: 400)

Example :

Poleica.configure do |config|
  config.timeout = 2 # time in secs
  config.libre_office[:bin_paths][:linux] = '/usr/local/bin/gm'
  config.graphics_magick[:bin_paths][:osx] = '/Applications/OpenOffice.app/Contents/MacOS/soffice.bin'
end

• weight : pixels number
• width : pixels number
• force_resize : boolean(false) (it doesnt preserve the image ratio)
• path : string folder or file
• auto_orient : boolean(true) (keep the orientation extracted from EXIF)

• GraphicsMagick (gm) >= 1.3.18 (for auto-rotate)
• LibreOffice

• It should be easy
• It should work on MacOS & Linux
• It should handle standard files
• It should convert to PNG or PDF

• Documents: PDF, PPT, DOC, TXT..
• Images: PNG, JPEG, GIF...

• I wrote mimetype not mime_type

• If you want to disable .~lock.#{file_name}# creation in /tmp just : export SAL_ENABLE_FILE_LOCKING=0
• Exit LibreOffice App before tests and launch

• A lot of inspiration from a lot of gems :
  • Docsplit
  • Paperclip
  • ROM
  • ...
