Welcome to the ndarray-vector-uint8c repository! This project focuses on creating a clamped unsigned 8-bit integer vector, which is essentially a one-dimensional ndarray. This type of data structure is useful in various applications, especially in image processing, where pixel values are often represented as 8-bit integers.
The ndarray-vector-uint8c library provides an efficient way to handle unsigned 8-bit integer vectors. These vectors can store values ranging from 0 to 255. The clamping feature ensures that any values outside this range are adjusted to fit within it. This makes the library particularly valuable for tasks involving graphics and data manipulation.
The library is built using JavaScript and is compatible with Node.js. It aims to provide a simple yet powerful API for developers who need to work with numeric data efficiently.

To install the ndarray-vector-uint8c library, you can use npm. Run the following command in your terminal:
npm install ndarray-vector-uint8cThis command will download the package and add it to your project's dependencies.
To use the library, you need to require it in your JavaScript file. Here’s a basic example:
const { VectorUint8C } = require('ndarray-vector-uint8c');
const vector = new VectorUint8C(10); // Create a vector of length 10
vector.set(0, 255); // Set the first element to 255
console.log(vector.get(0)); // Outputs: 255The clamping feature automatically adjusts any values that exceed the 0-255 range. For example:
vector.set(1, 300); // Attempt to set value outside the range
console.log(vector.get(1)); // Outputs: 255The main constructor for creating a new unsigned 8-bit integer vector is VectorUint8C.
length(number): The desired length of the vector.
const vector = new VectorUint8C(5);Sets the value at the specified index. The value is clamped between 0 and 255.
- Parameters:
index(number): The index to set.value(number): The value to set.
Retrieves the value at the specified index.
- Parameters:
index(number): The index to retrieve.
vector.set(2, 128);
console.log(vector.get(2)); // Outputs: 128Here are some examples of how to use the ndarray-vector-uint8c library in various scenarios.
const { VectorUint8C } = require('ndarray-vector-uint8c');
const vector = new VectorUint8C(5);
vector.set(0, 100);
vector.set(1, 200);
vector.set(2, 300); // This will be clamped to 255
console.log(vector.get(0)); // Outputs: 100
console.log(vector.get(1)); // Outputs: 200
console.log(vector.get(2)); // Outputs: 255You can iterate over the vector to perform operations on each element.
for (let i = 0; i < vector.length; i++) {
console.log(vector.get(i));
}You can initialize a vector with values from an existing array.
const initialValues = [50, 150, 250];
const vector = new VectorUint8C(initialValues.length);
initialValues.forEach((value, index) => {
vector.set(index, value);
});
console.log(vector.get(0)); // Outputs: 50
console.log(vector.get(1)); // Outputs: 150
console.log(vector.get(2)); // Outputs: 250We welcome contributions to the ndarray-vector-uint8c project. If you have ideas for improvements or new features, feel free to fork the repository and submit a pull request.
