random color image frames cannot be encoded in high quality due to the bandwidth limitation. and it doesn't look so nice visually either. i recommend using black and white patterns for stereogram animation.

in JavaScript/AppleScript:

Code: Select all

//   drop generate SIRDS AppleScript/JavaScript droplet for Sirds 
//
//   Copyright (c) 2006-2021 Katsura Shareware. All rights reserved. 
//    
//   generates stereogram image files from .png depth map image files/folders dropped on to this AppleScript/JavaScript droplet. 

// wall-eyed:  set useCrossEyedView to false
// cross-eyed: set useCrossEyedView to true
var useCrossEyedView = false

// random dot:    set usePatternImage to false
// pattern image: set usePatternImage to true
var usePatternImage = false
var patternImage = null

var fileManager = $.NSFileManager.defaultManager
var app = Application.currentApplication()
app.includeStandardAdditions = true

//
// input:
//   path: "abc.png",
//   replacement: "_bw.png" (black and white) or "_pi.png" (pattern image)
// output:
//   "abc_bw.png" or "abc_pi.png"
//
function replaceExtension(path, replacement) {
  return path.substring(0, path.lastIndexOf(".")) + replacement
}

function processFile(aFile) {
   var Sirds = Application("Sirds")
   var suffix

   // set all the preferences first
   if (usePatternImage) {
      Sirds.patternMode = "image file"
	  Sirds.pattern = patternImage
	  suffix = "_pi.png"
   } else {
      Sirds.patternMode = "random"
      Sirds.randomDotColor = "black and white"
      Sirds.randomDotShape = "random shapes"
	  suffix = "_bw.png"
   }
   Sirds.resolution = 85
   if (useCrossEyedView) {

	 Sirds.maximumDepth = 14
   } else {
     Sirds.viewMode = "wall eyed"

	 Sirds.maximumDepth = 14
   }
   Sirds.eyeSeparation = 2.5
   Sirds.oversampling = "four times"
   Sirds.showGuide = false
   Sirds.invertDepth = false

   var exportFilePath = Path(replaceExtension(aFile.toString(), suffix))

   console.log(exportFilePath.toString())

   var doc = Sirds.open(aFile)

   for (var item of folderItems) {
     var currentItem = `${folderString}/${item}`
     openDocuments([currentItem])
   }

// dropped file or folder gets passed to this "on open" action
