Abstract

The invention discloses a picture clipping method and device and computer equipment. The picture cutting method comprises the following steps: cutting a picture, receiving a picture cutting instruction input by a user, performing corresponding equal-ratio processing on the first cut picture according to a preset pop-up layer, receiving the size of the cutting frame; determining the actual size ofthe cutting frame in the first cutting picture; the size of the cut box is determined according to the ratio of the width to the height of the cutting frame; therefore, the scaling of the first cut picture is determined; scaling the first cut picture according to the scaling ratio, and a cutting area of the cutting frame in the target cutting picture, according to the left offset and the upper offset of the tailoring area, the tailoring area is tailored; according to the method, the position of the cropping area in the target cropping picture is determined, the images outside the cropping areaare hidden, all pixel contents of the whole picture do not need to be read into a memory, the picture cropping function is achieved under the condition that a new picture does not need to be output again, and therefore the picture cropping efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a picture clipping, device and computer equipment. Background technique [0002] With the rapid development of image processing technology, image processing software developers provide more and more types of image processing software with more and more functions. The current mainstream image processing software all have the function of image cropping. The picture cropping function is one of the main functions necessary for many image processing software or picture websites nowadays. It allows users to crop the uploaded pictures to obtain a new cropped picture. [0003] The current method of image cropping is to import the original image that needs to be cropped, and then output a new cropped image after clipping the original image. At present, almost all image cropping functions in the world are realized by using the new feature canvas of html5. Before the canvas came...
