另外，相关技术中，用户手动设置预览封面，用户需要选取背景图像、目标虚拟元素、设置封面文本，再将封面文本和目标虚拟元素添加至背景图像，需要耗费较长的时间，时间成本较高，且用户在不知道什么样的背景图像、目标虚拟元素和封面文本更加吸引用户的情况下，设置的预览封面的显示效果也会较差。In addition, in the related art, the user manually sets the preview cover, the user needs to select the background image, the target virtual element, set the cover text, and then add the cover text and the target virtual element to the background image, which takes a long time and costs a lot of time. , and if the user does not know what kind of background image, target virtual element and cover text are more attractive to the user, the display effect of the set preview cover will also be poor.

并且，响应于预览封面生成指令，能够获取封面文本，将封面文本和目标虚拟元素添加至背景图像中，得到预览封面，不需要用户手动设置封面文本，根据背景图像、目标虚拟元素和封面文本生成预览封面的过程中，用户也不需要执行任何操作，能够一键生成多媒体资源的预览封面，高了生成预览封面的效率，降低了成本。In addition, in response to the preview cover generation instruction, the cover text can be obtained, the cover text and the target virtual element can be added to the background image, and the preview cover can be obtained. The user does not need to manually set the cover text, and is generated according to the background image, the target virtual element and the cover text. In the process of previewing the cover, the user does not need to perform any operation, and can generate the preview cover of the multimedia resource with one click, which improves the efficiency of generating the preview cover and reduces the cost.

并且，能够同时得到多媒体资源的多个预览封面，实现预览封面的批量生成，进一步提高了获取预览封面的效率，降低了成本。在生成预览封面之后，还能够进一步调整生成的预览封面，提高了灵活性。In addition, multiple preview covers of multimedia resources can be obtained at the same time, and batch generation of preview covers can be realized, which further improves the efficiency of obtaining preview covers and reduces costs. After the preview cover is generated, the generated preview cover can be further adjusted, which improves flexibility.
