Background
Drawing tools such as an existing drawing board, an image editor, a photo editor and the like generally have the functions of drawing, erasing, canceling and restoring, wherein the technical difficulty is how to cancel the image editing operation. The prior art is mainly realized by adopting the following two schemes: (1) when the operation is cancelled, all the actions before the operation needing to be cancelled are redrawn once; (2) in the process of editing the image, each time the image is edited, a currently edited image is saved, and when the image is cancelled, the previous image corresponding to the operation to be cancelled is obtained.

Scheme (2) needs to store multiple pictures, and frequent revocation increases IO operations of the device, consumes a large amount of memory, and is inefficient. Therefore, it is known that how to reduce the memory consumption and the performance consumption in the revocation process of the image editing operation and improve the revocation efficiency of the image editing operation is a technical problem to be solved urgently.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The embodiment of the present disclosure provides a method for undoing an image editing operation, as shown in fig. 1, including the following steps:
step S1, acquiring image editing operation, and correspondingly storing an image every preset interval operation times;
the single continuous image editing operation represents one image editing operation, for example, one image editing operation performed from when the finger touches the screen to when the finger leaves the screen, one image editing operation performed from when the mouse clicks the screen to when the mouse is released, or the like. It can be understood that, every preset number of operations at intervals, when one image is stored, an image number is set for the stored image.
Step S2, receiving an operation canceling instruction, and acquiring a first image closest to an editing operation to be canceled and all image editing operations after the image editing operation corresponding to the first image and before the editing operation to be canceled from the stored image;
step S3, generating a target image based on the first image and all image editing operations after the image editing operation corresponding to the first image and before the operation to be undone.
Based on the method disclosed by the embodiment of the disclosure, the image storage capacity and the times of image editing operation needing to be executed in the revocation process can be reduced, the memory consumption and the performance consumption in the revocation process of the image editing operation are reduced, and the revocation efficiency of the image editing operation is improved.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
As an example, step S1 further includes:
step S11, acquiring a coordinate point set corresponding to each image editing operation except the image editing operation corresponding to the saved image;
and step S12, storing a coordinate point set corresponding to each image editing operation.
In step S11, all coordinate points corresponding to each image editing operation may be directly stored to obtain a corresponding coordinate point set, but when the number of coordinate points is too large, a larger memory may be occupied, which affects the efficiency of canceling the image editing operation.
The first embodiment,
Step S11 specifically includes the following steps:
step S111, storing an initial coordinate point of each image editing operation;
and step S112, when the storage time of the coordinate point on the time distance of the image editing operation is equal to a preset time interval threshold value, storing the coordinate point corresponding to the time point into a coordinate point set corresponding to the image editing operation.
It can be understood that the preset time interval threshold value needs to satisfy that an image drawn based on the finally obtained coordinate point set and an image drawn by the original image editing operation are within a preset error range, and the preset error range satisfies that human eyes cannot find that the image drawn based on the finally obtained coordinate point set and the image drawn by the original image editing operation have a difference. Through the steps S111-S112, the storage number of coordinate points in the coordinate point set can be greatly reduced, the memory occupation amount is reduced, the number of coordinate points can also be reduced in the process of redrawing the image editing operation in the revocation process, and the revocation efficiency of the image editing operation is improved.
The second embodiment,
Step S11 specifically includes the following steps:
step S101, storing an initial coordinate endpoint of each image operation and edition;
and S102, when the distance between the coordinate point of the image editing operation and the coordinate point of the last coordinate point is less than or equal to a preset distance interval threshold value, storing the coordinate point to a coordinate point set corresponding to the image editing operation.
It can be understood that the preset distance interval threshold value needs to satisfy that an image drawn based on the finally obtained coordinate point set and an image drawn by the original image editing operation are within a preset error range, and the preset error range satisfies that human eyes cannot find that the image drawn based on the finally obtained coordinate point set and the image drawn by the original image editing operation have a difference. Through the steps S101 to S102, the storage quantity of coordinate points in the coordinate point set can be greatly reduced, the memory occupation quantity is reduced, the quantity of the coordinate points can also be reduced in the process of redrawing the image editing operation in the revocation process, and the revocation efficiency of the image editing operation is improved.
As an example, in step S2, the obtaining a first image closest to the editing operation to be undone from the stored images may specifically include the following steps:
step S21, determining the image number N of the first image closest to the editing operation to be undone:
N＝(m％n)*n
wherein,% represents the operation of solving the modulus, m is the number of the editing operation to be cancelled, and n is the interval times;
and step S22, acquiring an image corresponding to the image number, where the image is the first image.
As an example, step S3 may specifically include: and drawing a coordinate point set corresponding to each image editing operation from the image editing operation corresponding to the first image to the operation to be cancelled on the first image by taking the first image as an initial image, and generating the target image.
As an example, the value range of the number of interval operations may be set to [100,1000], and the number of interval operations in this range can ensure high revocation efficiency. When the maximum undo time is in the range of [100,1000], the interval operation time can be directly equal to the maximum undo time, and thus the setting can improve the undo efficiency of the image editing operation to a greater extent. The maximum revocation frequency refers to the maximum revocable frequency set on drawing tools such as drawing boards, image editors and photo editors, and the numerical revocation frequency can be defined by the tools or the users. However, it is understood that when the maximum revocation number is in the range of [100,1000], the number of interval operations is not limited to be equal to the maximum revocation number, and the corresponding number of interval operations may be selected in [100,1000] according to specific application requirements.
An embodiment of the present disclosure further provides a revocation apparatus for image editing operation, as shown in fig. 2, including: the image editing device comprises a first acquisition module 1, a second acquisition module 2 and an image generation module 3, wherein the first acquisition module 1 is used for acquiring image editing operation and correspondingly storing an image every preset interval operation times; the second obtaining module 2 is configured to receive an operation cancelling instruction, and obtain, from a stored image, a first image closest to an editing operation to be cancelled and all image editing operations after an image editing operation corresponding to the first image and before the editing operation to be cancelled; and the image generating module 3 is configured to generate a target image based on the first image and all image editing operations after the image editing operation corresponding to the first image and before the operation to be undone. Based on the device disclosed by the embodiment of the disclosure, the image storage capacity and the times of image editing operation needing to be executed in the revocation process can be reduced, the memory consumption and the performance consumption in the revocation process of the image editing operation are reduced, and the revocation efficiency of the image editing operation is improved.
As an example, the first obtaining module 1 further includes a coordinate point obtaining unit and a coordinate point storage unit, wherein the coordinate point obtaining unit is configured to obtain a set of coordinate points corresponding to each image editing operation other than the image editing operation corresponding to the saved image; the coordinate point storage unit is used for storing a coordinate point set corresponding to each image editing operation.
It should be noted that the coordinate point obtaining unit may directly store all coordinate points corresponding to each image editing operation to obtain a corresponding coordinate point set, but when the number of coordinate points is too large, a large memory may be occupied, and the cancellation efficiency of the image editing operation is affected.
The first embodiment,
The coordinate point acquisition unit comprises a first coordinate point acquisition subunit and a second coordinate point acquisition subunit, wherein the first coordinate point acquisition subunit is used for storing the initial coordinate point of each image editing operation; and the second coordinate point acquisition subunit is used for storing the coordinate point corresponding to the time point to the coordinate point set corresponding to the image operation editing operation when the storage time of the coordinate point at the time distance of the image editing operation is equal to a preset time interval threshold value. The first coordinate point acquisition subunit and the second coordinate point acquisition subunit can greatly reduce the storage quantity of coordinate points in the coordinate point set, reduce the memory occupation quantity, reduce the quantity of coordinate points in the process of redrawing the image editing operation in the revocation process, and improve the revocation efficiency of the image editing operation.
The second embodiment,

As an example, the second acquiring module 2 includes a first image acquiring unit for acquiring, from the stored images, a first image closest to the editing operation to be undone, the first image acquiring unit including a number determining subunit and a first image acquiring subunit, wherein the number determining subunit is configured to determine an image number N of the first image closest to the editing operation to be undone:
N＝(m％n)*n
wherein,% represents the operation of solving the modulus, m is the number of the editing operation to be cancelled, and n is the interval times;
and the first image acquisition subunit is used for acquiring the image corresponding to the image number.
As an example, the image generating module 3 is specifically configured to use the first image as an initial image, and draw, on the first image, a set of coordinate points corresponding to each image editing operation after the image editing operation corresponding to the first image is performed to before an operation to be undone, so as to generate the target image.
As an example, the value range of the number of interval operations may be set to [100,1000], and the number of interval operations in this range can ensure high revocation efficiency. When the maximum undo time is in the range of [100,1000], the interval operation time can be directly equal to the maximum undo time, and thus the setting can improve the undo efficiency of the image editing operation to a greater extent. The maximum revocation frequency refers to the maximum revocable frequency set on drawing tools such as drawing boards, image editors and photo editors, and the numerical revocation frequency can be defined by the tools or the users. However, it is understood that when the maximum revocation number is in the range of [100,1000], the number of interval operations is not limited to be equal to the maximum revocation number, and the corresponding number of interval operations may be selected in [100,1000] according to specific application requirements.
