Re: Replace layer?

Le=F3nidas,

> My goal is to replace the gif image that is in a layer.

The problem here is that all the images which are used in .swf are
just some special case of shape fill, so they always go with a shape.
So order to replace an image you need to modify the shape also.

In general this is not a trivial task, because it may require to
completely parse a shape with all its information, replace transformation
matrix and so on. I was doing similar gig recently and ran into that prob=
lem
when the client requested that the image to be replaced could be scaled a=
nd
aligned inside the replaced image place. If you just need to replace one =
gif
file with another of the same dimensions then you can use the code below.=
 If you
need more flexibility (like scaling and aligning) then I would suggest yo=
u
do it yourself, because unfortunately I cannot publish the code here whic=
h I was paid for.

             FlashFile file ...;

             String flash_path =3D .....;      // name of image in the fi=
le
             String image_path =3D .....;      // name of new image file
             FlashDef def =3D file.getDefFromLibrary(flash_path);
             if( !(def instanceof Bitmap) ) {
                 Log.error("Symbol '"+flash_path+"' is not a bitmap, igno=
red.");
                 continue;
             }
             Bitmap old_img =3D (Bitmap) def;
             Bitmap new_img =3D Bitmap.newBitmap(image_path);
             file.removeDef(old_img);
             file.addDefToLibrary(flash_path, new_img);
             new_img.setID(old_img.getID());
             Hashtable processed =3D new Hashtable();

             for( Enumeration e =3D file.definitions(); e.hasMoreElements=
(); ) {
                 FlashDef def =3D (FlashDef) e.nextElement();
                 if( def instanceof LazyShape ) {
                     LazyShape shape =3D (LazyShape) def;
                     IVVector bitmaps =3D shape.getBitmaps();
                     if( bitmaps !=3D null ) {
                         boolean is_replaced =3D false;
                         for( int h=3D0; h<bitmaps.size(); h++ ) {
                             LazyShape.BitmapRef bref =3D (LazyShape.Bitm=
apRef) bitmaps.elementAt(h);
                             if( bref.bitmap =3D=3D old_img ) {
                                 bref.bitmap =3D new_img;
                                 is_replaced =3D true;
                             }
                         }
                         if( is_replaced ) {
                             Rectangle2D bounds =3D shape.getBounds();
                         }
                     }
                 }
             }
