AI-generated Key Takeaways
-
The
ee.PixelTypefunction returns a PixelType object based on specified precision, optional value limits, and dimensionality. -
The function accepts 'int', 'float', or 'double' for the
precisionargument. -
Optional
minValueandmaxValuearguments can define the range of pixel values. -
An optional
dimensionsargument specifies the number of dimensions, defaulting to 0 for a scalar.

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. |
