// listOfFiles : File[] or String[]
// targetWidth/targetHeight : int, pixel
// doStretch : boolean for ignoring aspect ratio
// processBiggerFiles : boolean for allowing upscale
ResizeProcessor.resizeImagesWithThese(listOfFiles, targetWidth, targetHeight, doStretch, processBiggerFiles);

// doStretch : boolean for ignoring aspect ratio
// processBiggerFile : boolean for allowing upscale
