ee.PixelType
Returns a PixelType of the given precision with the given limits per element, and an optional dimensionality.
Usage | Returns |
---|
ee.PixelType(precision, minValue, maxValue, dimensions) | PixelType |
Argument | Type | Details |
---|
precision | Object | The pixel precision, one of 'int', 'float', or 'double'. |
minValue | Number, default: null | The minimum value of pixels of this type. If precision is 'float' or 'double', this can be null, signifying negative infinity. |
maxValue | Number, default: null | The maximum value of pixels of this type. If precision is 'float' or 'double', this can be null, signifying positive infinity. |
dimensions | Integer, default: 0 | The number of dimensions in which pixels of this type can vary; 0 is a scalar, 1 is a vector, 2 is a matrix, etc. |
Examples
print(ee.PixelType('int', 0, 1)); // int ∈ [0, 1]
print(ee.PixelType('int', -20, -10)); // int ∈ [-20, -10]
print(ee.PixelType('float')); // float
print(ee.PixelType('double')); // double
print(ee.PixelType('double', null)); // double
print(ee.PixelType('double', null, null)); // double
print(ee.PixelType('double', null, null, 0)); // double
print(ee.PixelType('double', null, null, 1)); // double, 1 dimensions
print(ee.PixelType('double', null, null, 2)); // double, 2 dimensions
print(ee.PixelType('double', null, null, 3)); // double, 3 dimensions
print(ee.PixelType('double', null, null, 10)); // double, 10 dimensions
print(ee.PixelType('double', null, null, 1e8)); // double, 100000000 dimensions
print(ee.PixelType('double', 1, 2, 0)); // double ∈ [1, 2]
print(ee.PixelType('double', 1, 3, 2)); // double ∈ [1, 3], 2 dimensions
print(ee.PixelType('double', -4, -3, 0)); // double ∈ [-4, -3]
print(ee.PixelType('double', null, 2.3, 0)); // double
print(ee.PixelType('double', 3.4, null, 0)); // double
