Benefits of technology
[0034]本发明提供的一种Wayland环境下X窗口缩放的实现方法、装置、电子设备及存储介质，使用XWayland rootless模式，该方法通过在多个显示器中统计缩放因子并选取最大值作为处理XWayland窗口的全局缩放因子max_scale，Wayland合成器能够同步更新发送给XWayland使用的xdg_output大小以及XWayland所使用的xft.dpi，从而使X11应用依据正确的DPI值重新绘制图形内容并生成高分辨率的buffer，有效提升窗口显示的清晰度。同时，Wayland合成器在接收XWayland传输的surface几何信息时，通过xwayland_unscale函数进行反向缩放，将物理坐标准确转换为逻辑坐标，在向XWayland返回surface信息时，再通过xwayland_scale函数将逻辑坐标转换回物理坐标，确保逻辑坐标系与物理坐标系的一致性和交互准确性。

Abstract
The application provides an implementation method, device and equipment of X window scaling under a Wayland environment and a storage medium, the method comprising: selecting max_scale, updating and sending relevant information of max_scale to XWayland; then adjusting the screen size and geometric coordinates of a virtual device, saving and notifying X11 of updated xft.dpi; X11 draws a buffer according to the scaled screen size and the updated xft.dpi, converts wl_surface and wl_buffer based on the buffer; after the Wayland compositor receives the surface, reverse scaling is performed; when the surface is returned, the surface is sent after scaling conversion according to max_scale. In this way, the method can solve the problem of display blur of XWayland in a high-resolution scene.
