[Sur] Etoys Fotos sin Fondo - Photos with no background

[Pato Acevedo]

Hola:

En el minuto 2:27 del video enviado hoy a la lista, me acorde de este pendiente.

    Una vez que toma el "grab patch" del area seleccionada, obtiene los halos de  la imagen,  y con el halo gris obtiene la paleta de colores, que en su barra superior dice "no color". Despues se selecciona la herramienta tarro de pintura, y se "pinta" de color transparente. Solo sirve para imagenes que tengan un fondo de un solo color.

Subject: [Sur] Etoys Fotos sin Fondo - Photos with no background



Someone asked today how to eliminate the background in a picture.
I recall this problem was explained in one of the Waveplace videos by Tim Falconer.
The link to that video apparently is no longer working,  lesson No. 29:

We needed an image of the triceratops without a background,  so it was free to chase Seymour the Turtle.
The only solution I found is to find a graphic with no background like these ones from 
www.openclipart.org
The question came back to us today because someone wants to take pictures with the XO and keep only the main subject,  let�s say a person,  not the whole picture.
Thanks for any comments that could help in this area.
