Check out the new article: MQL5 Trading Tools (Part 16): Improved Super-Sampling Anti-Aliasing (SSAA) and High-Resolution Rendering.

We add supersampling‑driven anti‑aliasing and high‑resolution rendering to the MQL5 canvas dashboard, then downsample to the target size. The article implements rounded rectangle fills and borders, rounded triangle arrows, and a custom scrollbar with theming for the stats and text panels. These tools help you build smoother, more legible UI components in MetaTrader 5.

The anti-aliasing and high-resolution rendering framework addresses visual artifacts in digital graphics, such as jagged edges or "aliasing" that occur when continuous shapes are represented on a discrete pixel grid. Aliasing manifests as stair-step patterns on lines, curves, or borders, reducing clarity and professionalism in displays like our trading dashboards. To mitigate this, techniques like supersampling render scenes at a higher resolution—typically multiples of the target size—then downsample by averaging pixel values, smoothing edges through color blending, and creating a more natural appearance. See an example of the super-sampling process below.

On the other hand, high-resolution rendering complements anti-aliasing by utilizing larger canvases to capture finer details before reduction, enhancing overall image quality without increasing final output size. This is particularly significant in MQL5 applications, where precise visualizations of market data, such as graphs and stats, improve user comprehension and decision-making by minimizing distortions. For instance, bicubic interpolation, a sophisticated resampling method, calculates new pixel values using a weighted average of surrounding pixels, preserving smoothness during scaling operations and contributing to superior anti-aliased results.
