##thumbnailmagic

A CFML-based tool for generating thumbnails from a variety of sources.

* images
* text files
* videos
* PDFs
* OpenOffice documents
* web pages

###Version: 0.9

See the examples page for examples of how to generate thumbnails for each source.

###Dependencies

ThumbnailMagic depends on the following external libraries that you must install yourself:

* JDK 7
* ffmpeg - used for rendering video thumbnails
* NodeJS - used for rendering web page thumbnails.
* OpenOffice - used for rendering thumbnails of MSOffice documents and multi-page or high quality thumbnails of OpenOffice documents

ThumbnailMagic packages the following external dependencies with the distribution:

* node-webshot - used for rendering web page thumbnails. Webshot is included in the distribution
* Apache Tika ( OS X Only ) - used to determine mime type of thumbnail source. If you are running OS X, 
  copy the included /lib/tika-app-1.6.jar file into your CFML engine's classpath.

###Installation

  1. Download the archive of the project, or clone the repo using Git:

    git clone https://github.com/robertdmunn/thumbnailmagic.git

  2. Adding ThumbnailMagic to a CFML project:

    a. Copy the ./thumbnailmagic folder into your project

    or

    b. Map the ./thumbnailmagic folder to /thumbnailmagic in your CFML engine's administrator.

Optional

  1. Verify NodeJS is installed for web page thumbnail support

    Type node at a command prompt. If node is installed and mapped on your PATH, you will get a node shell:

    >

  2. Verify ffmpeg is installed for video thumbnail support.

    Type ffmpeg at a command prompt. If ffmpeg is installed and mapped on your PATH, you will see something like the following:

    $ ffmpeg version 2.3.2 Copyright (c) 2000-2014 the FFmpeg developers

  3. Verify OpenOffice is installed for MSOffice/OpenOffice multi-page thumbnail support

    a. Copy the jars from /lib/jodconverters into your CFML engine's classpath.

    b. Current configuration runs OpenOffice service on localhost port 8100. Adjust settings in /thumbnailmagic/system/oolib.cfc.

###Usage

  1. Instantiate the service:

    service = new thumbnailmagic.ThumbnailService( thumbnailPath = expandPath( "./tiles/" ) );

  2. Configuring for Coldbox

    If you are using Wirebox, just refer to ThumbnailServiceColdbox in your Wirebox configuration:

       map( "ThumbnailService" ).to( "thumbnailmagic.ThumbnailServiceColdbox" )
          .asSingleton();	
    

    You only need a thumbnailpath setting in your Coldbox configuration:

     	thumbnailPath = "<local path to thumbnails>" 
    

Generating thumbnails:

// pass either a filepath and filename or a uri // options is an optional argument in the form of a struct

   options = { 
   
   height : <number of pixels> (default: 200), // height of resulting thumbnail 
   width : <number of pixels>,  // width of resulting thumbnail, leave out to scale width in proportion to height 
   overwrite: "overwrite|rename|error" (default overwrite),  // whether to replace existing thumbnails
   filename : <filename> // name of resulting thumbnail, e.g. "thumb.png"
   
   PDF only:
   
   scale: <percentage of original PDF>, ( default: 30) // scale of intermediate thumbnail 
   pages: <command separated list> (default 1), // pages to render, e.g. 1,2 or 1,3-5,11-15,50 or 1-90 
   
   video only:
   
   rate : <number> (default 1), // number of seconds between snapshots 
   frames : <number> (default 1), // total number of thumbnails to create
   start : <time> (default 00:01:00), // starting point in the video, e.g. 00:01:00 (one minute into video)
   timeout : <seconds> (default 60), // how long the video thumbnail process should run before timing out
   
   }


 service.createThumbnail( filename, filepath | uri, options );

for URIs:

urithumbnail = service.createThumbnail( uri = "www.wikipedia.org" );

for images:

imgthumbnail = service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "sailrock.jpg", 
	options = {} );

for OpenOffice documents, spreadsheets, presentations, and graphics:

for thumbnail extraction from document (low quality):

oothumbnail =  service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "openoffice.odt" );

for thumbnail generation (high quality):

oothumbnail =  service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "openoffice.odt",
	options = {extract : false } );

with multiple pages:

oothumbnail =  service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "grimms_fairy_tales.doc", 
	options = { pages : "1,50-52,213" }   );

for PDFs:

pdfthumbnail = service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "Open Source.pdf", 
	options = { pages : "1,3,5-6" } );

for plain text files:

textthumbnail = service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "mitlicense.txt" );	   	

for videos:

videothumbnail = service.createThumbnail( 
	filepath = expandPath( "./" ), 
	filename = "spurting_plasma.mp4", 
	options = { rate : 1, frames : 1, start: "00:00:10" } );
