Description
Technical Field
The invention relates to the technical field of computers, in particular to a method and a system for generating an image occupying a bitmap.
Background
With the popularization of information technology, a wide variety of websites and app applications are currently filled on the internet, and there are a lot of image resources to be loaded in the applications. However, when the user loads the application for the first time or the network of the user is delayed, a problem of slow loading of a large amount of image resources occurs in the application, so that the browsing experience of the user is poor. Therefore, most of applications in the market replace the image resources which are not loaded completely by using a mode of occupying a bitmap, so that a user can expect the loaded image resources in advance. The occupation maps commonly used at present have the following two schemes:
(1) loading locally known size image assets in an application
In the application construction process, a set of low-quality images with known sizes are preprocessed for image resources at various positions of a page and stored to the local of an application, and the images are repeatedly referenced in the application. According to the technology, the image resources are generated locally in the application in advance, and the reference is carried out in the application page, so that the user can expect the loaded image resources before the page image resources are loaded. But this approach requires that the low quality pictures be processed and stored locally uniformly for different sizes of image resources in all pages in the application. Therefore, the above techniques are full of a lot of repeated work, and directly affect the development progress of the application.
(2) Loading in an application image resources generated by a device occupying a bitmap
By means of the existing or self-developed placeholder map device on the network, image resources corresponding to parameter data are generated according to different parameters, and image resource links are introduced into the application, so that the image resources of the placeholder map device can be loaded in advance before the image resources of the application page are loaded. By means of the image synthesis technology, the corresponding parameter data image resources are generated according to the image parameter data transmitted by the user on the links, and the work that an application developer repeatedly generates the image resources in the process of construction is avoided. But this approach requires repeated references in the code to the links that generate the image parameter data. The placeholder map device always needs to generate images according to the repeatability of the request parameter data, and the situation that the loading of image resources is slow is easily caused, and the placeholder map device inevitably returns to the initial problem.
