Problems solved by technology

[0003] However, since a screen-sized video memory cannot be allocated on an embedded platform with small resources, the chip cannot enable offline video memory, which in turn causes the GUI class library to draw any controls, and the data needs to be immediately flashed to the LCD screen and display to the screen so that the user can see it immediately
At the same time, as long as a small control is updated on the interface, all associated controls must be refreshed once, otherwise it will cause abnormal interface problems

Abstract

The embodiment of the invention discloses a GUI fragment type rendering method and device based on a dirty rectangle mechanism, electronic equipment and a storage medium. According to the method of the invention, a fragment video memory smaller than a screen video memory is created on an embedded platform in advance; when content drawing is carried out, a redrawing area is determined based on a dirty rectangle mechanism, if the redrawing area is larger than a segment video memory, the redrawing area is correspondingly sliced into a plurality of segment areas, the segment areas are drawn in thesegment video memory one by one, and picture drawing and screen refreshing are carried out in real time through the segment video memory. By adopting the method, the picture drawing efficiency of thesmall-resource embedded platform is improved through the fragment video memory in combination with the dirty rectangular rendering mechanism, and the screen refreshing frequency and the data area arereduced by limiting the size of the redrawing area, so that the overall performance of the screen is improved, and the impression experience of a user is optimized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of graphical user interface rendering, and in particular, to a GUI segment rendering method and device based on a dirty rectangle mechanism. Background technique [0002] At present, in the embedded platform, in order to make the user look and feel better, it is usually necessary to intuitively display the graphical user interface on the screen, so as to optimize the user experience. On some embedded platforms with small resources, such as STM32F103, due to its relatively small memory, the on-chip SRAM is only 64KB. Therefore, if you want to provide users with a better visual experience, you need to connect an 8MB SRAM, or directly send the GUI data to the LCD to refresh the GRAM (that is, the dedicated video memory of the LCD display) without opening up the video memory. This type of chip can use a 320*240 resolution, RGB565 LCD screen to enhance the user experience. In order t...
