Ciao a tutti.
Non sono affatto un profondo conoscitore di flash e qualche tempo fa avevo trovato sul web un "compositore" di slide show che mi aveva dato come risultato questo:
http://www.a4passidalmare.com/IT/aff...erre-2_it.html
purtroppo ho perso il software e non ho il .fla di partenza.
Adesso devo cambiare le fotografie e non sono stato più in grado di trovare alcunché per ottenere qualcosa di analogo.
Qualcuno sa come potrei fare?
Il problema è anche che nell'swf di cui sopra le immagini verticali ed orizzontali vengono trattate nello stesso modo, mentre utilizzando come punto di partenza lo script che segue (che è l'unica cosa che sono riuscito a trovare), ottengo erriori di visualizzazione o nelle thumb o nelle foto grandi (in pratica non riesco a far variare il contenitore in relazione all'orientamento della fotografia). Ecco lo script:
/********* DECLARE AND INITIALIZE VARIABLES **************************/
// names of folder and pictures, in the order to put them into the slider

"flower_orange",
"flower_yellow",
"flower_pink",

// constants
var PICPATH:String = "flowers/"; // folder with jpgs
var NPICS:Number = picnames.length; // number of pictures to load
var PICX:Number = 10; // x loc of big picture
var PICY:Number = 10; // y loc
var THUMBHOLDERX:Number = 0; // x location of thumbnail holder movieclip

var TOTALBYTES:Number = 212000; // approx sum of bytes in all jpgs (x 2)
var MAXPIXELS:Number = 12; // max number of pixels to move slider per frame
// mask definition; mask is assumed to cover some part of the thumbnail slider (here the numbers
// were chosen so that there are margins between the mask and the right and left edges of the movie
// (which is 420 x 290), and enough space above and below the thumbs to show them when they 'grow'
// on mouseover
var MASKX:Number = 10; // start x location of mask
var MASKW:Number = 400; // mask width
var MASKY:Number = 230; // start y location of mask
