Hola a Todos, <br><br><br>Necesito capturar la pantalla en Windows, solo que los intentos que he realizado, ninguno captura las interface transparentes como por ejemplo la ventana de buscar y reemplazar del notepad++.<br>
<br>
He intentado estos metodos y todos funcionan para capturar pantalla pero ninguno recoge las transparencias. ( no se ven las ventanas transparentes, como si no existiesen)<br><span style="color: rgb(25, 25, 25); font-family: Helvetica,Arial,sans-serif; font-size: 15px; line-height: 26px;"><br>
