Check out the new article: Creating Dynamic MQL5 Graphical Interfaces through Resource-Driven Image Scaling with Bicubic Interpolation on Trading Charts.
In this article, we explore dynamic MQL5 graphical interfaces, using bicubic interpolation for high-quality image scaling on trading charts. We detail flexible positioning options, enabling dynamic centering or corner anchoring with custom offsets.
We aim to build an MQL5 tool that embeds and scales images on MetaTrader 5 charts, creating dynamic, user-controlled graphical interfaces. We will load a bitmap image as a resource, scale it to fit chart dimensions using bicubic interpolation and position it based on user inputs like anchoring to corners or centering dynamically. This will allow us to overlay custom visuals—logos or patterns—while maintaining aspect ratios and toggling background or foreground display, all optimized for real-time performance. That way, the charts will be more interesting and appealing.
For scaling, we will use bicubic interpolation over nearest neighbor and bilinear methods. The closest neighbor produces pixelated results and bilinear blurs details. Here is a detailed visualization as to why we chose Bicubic Interpolation over the other methods.
