Ubuntu:

apt-get install imagemagick exiftool libcairo2-dev

Mac OS X (using Homebrew):

brew install imagemagick --disable-openmp

  - 0                                   # no resize (original size)
  - 1024                                # resize images 1024 pixels
  - 2048                                # resize images 2048 pixels
# ignoreWatermark:                      # If you don't want to add watermark , enable option as following.
#   - 0
#   - 1024
readDir:                                # Folder name including image to resize
  - ./sample JPG/targetFolder
distDir: ./sample JPG/resizedFolder     # Path where you want to output the resized image
watermark: src/sample-watermark.png     # File path of watermark image
watermarkWidthRate : 0.1                # The size of the image occupied by the watermark
watermarkMarginRate: 0.02               # Watermark margin
# defaultWatermarkPosition:             # Default position of watermark
#   - North
#   - West
# watermarkColor: auto                  # Watermark Color Overlay (e.g. : auto , 00FFFF , FF00FF , FFFF00 , red , green , blue , ...)
# colorTiefQuality: 50                  # If watermarkColor is auto, determine the quality to calculate the color. ( 1: High Quality and very slow , 10: Normal Quality and slow , 50: Reasonable quality and fast )
# colorTiefQuality_watermarkArea: 1     #
# watermarkColorSelectionWeight:        # Criteria for choosing the color of the watermark
#   - 1.0                               # Hue difference
#   - 1.0                               # Saturation difference
#   - 4.0                               # Luminance difference
# defaultLens: lens:laowa105mm          # Lens keyword to enter when there is no Exif
# parallelLimit: 4                      # Max number of processes to be processed in parallel. The value is recommended about twice the number of CPUs.

quality: 97                             # JPEG quality value


fileTitle: My Picture                   # Always a character string to be included in the IPTC title meta field
constTag:                               # Always a character string to be included in the IPTC keywords meta field

descriptionTemplate : desciption        # Always a character string to be included in the Exif desciption field

Then run node.js. Must install NodeJS from https://nodejs.org/ beforehand to launch with "node index.js"

$ node index.js resize

$ node index.js r

Control with keywords and Exif

You can customize processing with with photo included keywords and exif. For example , how to include keywords, please see the following.

How to use keywords in Lightroom

watermark position

You can customize the position of the watermark based on pos:****-**** keywords .

keywords to include in photos	watermark position
`pos:top-left`	NorthWest
`pos:top-right`	NorthEast
`pos:bottom-left`	SouthWest
`pos:bottom-right`	SouthEast
`pos:middle-center`	Center

You can change keywords from Photoshop or Lightroom, but you can also change them with the following commands.

$ node index.js position bottom right image1.jpg image2.jpg ...

Also , you can customize position rule . if you want to customize , please edit settings/watermarkPosition.json.

Manual input of lens information ( Exif and IPTC title )

When resizing, lens information can be entered automatically by keyword.

keywords to include in photos	Input lens information ( Exif and IPTC )
`lens:50mmf1.2s`	Ai Nikkor 50mm f/1.2S
`lens:laowa105mm`	LAOWA 105mm F2 Bokeh Dreamer STF

You can change keywords from Photoshop or Lightroom, but you can also change them with the following commands.

$ node index.js lens laowa105mm image1.jpg image2.jpg ...

Also , you can customize lens rule . if you want to customize , please edit settings/cameraLens.json.

Using Export Actions in Adobe Lightroom

For example, if you want to use Lightroom's Export Action, please describe Apple Script in Automator as follows.

function run(input, parameters) {
  
  var cdm = "cd \"$HOME/Desktop/your-cloned-dir/resize-and-watermark\"";
  var nvm = "nvm use 4.3.0";

  var Terminal = Application('Terminal')
  Terminal.activate()
  var terW1 = Terminal.windows[0]
  try{
    console.log(terW1.selectedTab.properties())
  }catch(e){
    Terminal.doScript("echo 'Hi terminal window 1'");
    terW1 = Terminal.windows[0]
  }
  waitDelay(terW1)

  Terminal.doScript( cdm , {in: terW1} )
  waitDelay(terW1)
  Terminal.doScript( nvm , {in: terW1} )
  waitDelay(terW1)
  Terminal.doScript( "node index.js resize" , {in: terW1} )
  waitDelay(terW1)
  
    return input;
}

function waitDelay(inTerminalWindow){
  delay(1)
  while( inTerminalWindow.selectedTab.busy() ){
    delay(1)
  }
}
