Benchmark: rgb vs rgba vs hex

HTML Preparation code:

<canvas id="canvasOne" width="400" height="400"></canvas>
<canvas id="canvasTwo" width="400" height="400"></canvas>
<canvas id="canvasThr" width="400" height="400"></canvas>

Script Preparation code:

var canvasOne = document.getElementById("canvasOne");
var ctxOne = canvasOne.getContext("2d");

var canvasTwo = document.getElementById("canvasTwo");
var ctxTwo = canvasTwo.getContext("2d");

var canvasThr = document.getElementById("canvasThr");
var ctxThr = canvasThr.getContext("2d");

Tests:

alpha
ctxTwo.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxTwo.fillRect(0, 0, 400, 400); ctxOne.beginPath(); ctxOne.fillStyle = 'rgba(255, 255, 255, 1)'; ctxOne.arc(200, 200, 100, 0, Math.PI * 2, true); ctxOne.fill();
no alpha
ctxTwo.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxTwo.fillRect(0, 0, 400, 400); ctxTwo.beginPath(); ctxTwo.fillStyle = 'rgb(255, 255, 255)'; ctxTwo.arc(200, 200, 100, 0, Math.PI * 2, true); ctxTwo.fill();
hex
ctxThr.fillStyle = 'rgba(255, 255, 255, 0.3)'; ctxThr.fillRect(0, 0, 400, 400); ctxThr.beginPath(); ctxThr.fillStyle = '#fff'; ctxThr.arc(200, 200, 100, 0, Math.PI * 2, true); ctxThr.fill();

Let's dive into the benchmarking world of MeasureThat.net.

**What is being tested?**

The provided benchmark measures the performance differences in color representation and alpha blending between three different methods:

1. **RGBA (Red, Green, Blue, Alpha)**: A color model that includes an alpha channel for transparency.
2. **RGB (Red, Green, Blue)**: A basic color model without an alpha channel.
3. **HEX (Hexadecimal color code)**: A string representation of a color using hexadecimal digits.

The benchmark focuses on the performance differences when drawing a filled circle with each color method.

**Options being compared**

There are three test cases:

1. **RGBA**: Using `rgba(255, 255, 255, 0.3)` for filling the background and `rgba(255, 255, 255, 1)` for the circle.
2. **No Alpha (RGB)**: Using `rgb(255, 255, 255)` for filling the background and no alpha channel for the circle.
3. **HEX**: Using `#fff` for filling the background and a HEX string representing white.

**Pros and Cons**

1. **RGBA**:
	* Pros: Supports transparency and is commonly used in web development.
	* Cons: May require additional calculations for alpha blending, which can impact performance.
2. **No Alpha (RGB)**:
	* Pros: Simple and efficient, as it doesn't require alpha channel calculations.
	* Cons: Lacks transparency support, which might be a limitation depending on the use case.
3. **HEX**:
	* Pros: A concise way to represent colors using hexadecimal digits.
	* Cons: Can be less readable and more prone to errors compared to RGB or RGBA.

**Library usage**

None of the test cases explicitly use any JavaScript libraries for color manipulation. However, some might rely on internal browser functions or utility libraries that are not explicitly mentioned.

**Special JS features or syntax**

The benchmark does not include any special JavaScript features or syntax beyond what is standard in modern web development (e.g., no ES6+ syntax).

**Alternatives**

Other alternatives for measuring color representation and alpha blending performance might involve:

1. **Using different color models**, such as HSL (Hue, Saturation, Lightness) or CMYK (Cyan, Magenta, Yellow, Black).
2. **Adding more complex shapes or patterns** to the drawing operations.
3. **Using a different rendering engine** or browser for benchmarking.

However, MeasureThat.net's focus on RGBA vs RGB vs HEX provides a clear and straightforward comparison of color representation performance in JavaScript.
