Devuelve un PixelType de la precisión determinada con los límites determinados por elemento y una dimensionalidad opcional.
| Uso | Muestra |
|---|
ee.PixelType(precision, minValue, maxValue, dimensions) | PixelType |
| Argumento | Tipo | Detalles |
|---|
precision | Objeto | Precisión del píxel, que puede ser "int", "float" o "double". |
minValue | Número, valor predeterminado: nulo | Es el valor mínimo de píxeles de este tipo. Si la precisión es "float" o "double", puede ser nulo, lo que significa infinito negativo. |
maxValue | Número, valor predeterminado: nulo | Es el valor máximo de píxeles de este tipo. Si la precisión es "float" o "double", puede ser nulo, lo que significa infinito positivo. |
dimensions | Número entero, valor predeterminado: 0 | Es la cantidad de dimensiones en las que pueden variar los píxeles de este tipo. 0 es un escalar, 1 es un vector, 2 es una matriz, etcétera. |
