  • Processing got an undocumented function called listPaths().
  • For its 1st parameter, we pass the path of the target folder as a String.
  • For its 2nd parameter we can pass 1 String w/ all the desired extensions.
  • Then it returns a String[] array of all paths from that folder path fully filtered out.
  • However, given its undocumented, in order to access it under Python Mode, we need to prefix it w/ this.. :-<
  • Here's a wrapper function for listPaths() I did, w/ all Processing's valid image extensions defined there already: \m/

  def getPathsFromFolder(folder, EXTS='extensions=,png,jpg,jpeg,gif,tif,tiff,tga,bmp'):
      return this.listPaths(folder, EXTS);
  

  Usage example: :-B

  def setup():
      global imagePaths
      imagePaths = getPathsFromFolder(this.dataPath(''))
  

  Replace the argument this.dataPath('') w/ the String folder path where your images are. O:-)
