Abstract

The invention discloses a method for drawing a variable length and width background of a car entertainment system. The car entertainment system includes a frame for drawing graphics based on QT in Microsoft's embedded operating system WinCE, and is used to store various graphics used for display. The disk file system and memory of the file include the following steps: first start the background drawing program of the car entertainment system; then determine the size of the large background picture, load the nine picture resources required by the background drawing program into the memory, and then judge the background picture. Whether the memory space is loaded successfully. After the loading is successful, the corresponding background image is drawn at the corresponding position on the large background image according to the size of the large background image. The present invention reduces the Flash space occupied by background picture resources, increases the speed of loading pictures when drawing the background, improves work efficiency, reduces the time required for drawing background pictures, improves system efficiency, and avoids crashes due to memory application failures Increased risk.

Description

technical field [0001] The invention belongs to the field of vehicle entertainment systems, and in particular relates to a drawing method for a background with variable length and width of the vehicle entertainment system. Background technique [0002] With the rapid development of the national economy, people's quality of life has been continuously improved, prompting people to pay more attention to the quality of life and quality, and cars, as a necessary means of transportation for people to go to work, travel, and travel, have also developed rapidly, making People have higher requirements for cars. The rapid development of automobiles promotes the rapid development of the automotive electronics industry, making the vehicle multimedia system technology also wait for a rapid commission, and at the same time face new challenges. [0003] At present, the graphics drawing function of the commonly used vehicle-mounted multimedia host uses Microsoft's embedded operating system...
