Image stretching method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses an image stretching method and device, electronic equipment and a storage medium. The image stretching method comprises the steps of determining segmentation points in a to-be-stretched image; generating a first segmentation line and a second segmentation line which are perpendicular to each other by taking the segmentation point as an original point, so as to segment the to-be-stretched image into sub-images located in four quadrant regions; determining a target image area, filling four vertex angle areas of the target image area with the four sub-images according to quadrant areas where the sub-images are located, and copying common boundaries and segmentation points of two adjacent sub-images to fill the target image area to obtain a stretched target image. According to the image stretching method provided by the embodiment of the invention, the to-be-stretched image can be directly stored on the server without using a nine-point image, the process of storing image resources by the server is simplified, the image stretching method is realized by copying the boundary, is not limited by the model and is suitable for any model, and the stretched target image keeps the boundary details of the to-be-stretched image, so that the image stretching efficiency is improved. The display effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to an image stretching method, device, electronic equipment, and storage medium. Background technique [0002] In Android development, Dot9Picture, which supports adaptive dynamic stretching, is very popular. Dot9Picture is used in a wide range of scenarios, such as chat bubbles, new function guides, etc. Static images are usually Dot9Pictures. [0003] At present, when using Dot9Diagram on the Android terminal side, you need to put Dot9Diagram under the resource directory of the project on the terminal side, and call it directly through the code, which is simple and convenient. However, in actual application development, in order to make the product more flexible to adjust and change the image resources, the image resources need to be placed on the server, but the dot-nine image is directly sent from the server, and it cannot be adaptively stretc...
