The QgsRenderContext class in C++ is a representation of the rendering context used in QGIS. It provides information and settings related to the rendering process, such as the current map extent, scale, and DPI (dots per inch). Additionally, it holds the information about the rendering destination, including the output size and device-dependent properties. This class is used in various rendering-related operations, such as drawing symbols, labels, or map layers, and allows developers to access and modify the rendering context as needed during the rendering process.
