Description

Image processing method, electronic device, readable storage medium, and program product Technical Field The present application relates to the field of image processing technology, and in particular, to an image processing method, an electronic device, a readable storage medium, and a program product. Background With the rapid development of digital image processing technology, various graphic tools are available for users (such as plotters). For example, a plotter may draw an image on an electronic canvas using a professional drawing tool, and may use an image processing tool to assist in completing the image coloring. While drawing production may involve a large number of coloring objects, this requires the plotter to color each coloring object one by one, thus requiring great labor and time expenditure. Therefore, how to improve the efficiency of the coloring process on the image is a problem to be solved. Disclosure of Invention The application provides an image processing method, electronic equipment, a readable storage medium and a program product, which are used for improving the efficiency and accuracy of coloring an image. The application provides an image processing method which is applied to electronic equipment and comprises the steps of running a drawing application, displaying a first interface of the drawing application, displaying at least one frame of image in multiple frames of images of a first animation, responding to a first user operation for starting quick coloring, displaying M frames of images and a target image, wherein the M frames of images are thumbnails of at least one frame of image in multiple frames of images of the first animation, the target image is an enlarged image of an image to be colored in the multiple frames of images of the first animation or any other image in the M frames of images, acquiring at least one frame of reference frame image selected by a user from the M frames of images, wherein the at least one frame of reference frame image comprises coloring information, and generating a coloring image corresponding to the multiple frames of images of the first animation based on the at least one frame of reference frame image. For example, the electronic device may be an electronic device with a drawing tool (such as Application (APP)) installed, such as a tablet, a mobile phone (such as a folding screen mobile phone), and the like. The first interface may be, for example, a drawing interface displayed by the electronic device that includes controls that support rapid coloring. The first user operation may be, for example, a click operation for the control supporting quick coloring. The electronic device, in response to the first user operation, may display a drawing interface including the recommended M-frame image and prompting a user to select a reference frame image from the recommended multi-frame images. The drawing interface can display an image recommended by the electronic equipment based on the image processing method (such as the M frame image) as an alternative of the reference frame image. The user may select a part or an image from the recommended M frame images in the first interface as the reference frame image, i.e. the at least one frame reference frame image. Wherein the reference frame image needs to be a colored image. Therefore, the electronic equipment can divide the image sets of other images to be colored based on the reference frame image selected by the user and perform coloring treatment, so that the efficiency of the coloring treatment is improved. It can be understood that the M frame image recommended by the electronic device may include a colored image or an uncolored image. If the user selects the uncolored image as the reference frame image, the electronic device may output related prompt information to prompt the user to color (e.g., manually color) the uncolored image selected as the reference frame image, and then select the colored image as the reference frame image. In some embodiments, the target image may be an enlarged image of a currently drawn or selected image displayed by the system of the electronic device according to an operation of opening the animation function instructed by the user, or an image in a layer where the user stops at the time of opening the animation function for the first time. In other embodiments, the target image may be an enlarged image of any frame image determined from the recommended M frame images according to an operation of opening the animation function instructed by the user. In other embodiments, the target image may be an enlarged image of an image selected by the user from the M frame images, where the system of the electronic device opens the animation function according to the user instruction and the user clicks on the displayed thumbnail. Among the above-mentioned recommended M-frame images, the other images than the target image may be images displayed in a small image (e.g., t
