The present application claims the priority to a Chinese patent application filed with the Chinese Patent Office on Dec. 26, 2018, with application number of 201811599988.2, titled “METHOD FOR PROCESSING A SCREENSHOT IMAGE, ELECTRONIC DEVICE AND COMPUTER STORAGE MEDIUM”, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the technical field of image processing, and in particular to a method for processing a screenshot image, an electronic device and a computer storage medium.
In terms of information transmission, pictures are often more vivid and visual than text, and information conveyed in pictures is also more intuitive. In web pages or terminal application pages, information conveyed through pictures can be seen everywhere, and applications users also use pictures to share information. Many of the above-mentioned pictures as information carriers are taken from screenshot images of the pages. These screenshot images include the complete contents of the corresponding captured area, but part of the complete contents do not need to be presented to the user. For example, after taking a screenshot image of the playback interface, the obtained screenshot image includes a playback progress bar, the user cannot operate the progress bar, so it doesn't need to present the playback progress bar to the user.
In the prior art, how to deal with the above contents that does not need to be presented in the screenshot image is a problem to be solved.
In view of the above problem, the present disclosure is proposed in order to provide a method for processing a screenshot image, an electronic device and a computer storage medium that overcome the above problem or at least partially solve the above problem.

In order to enable the clearer understanding of the technical means of the present disclosure to be implemented according to the contents of the specification, and in order to make the above and other objects, features and advantages of the present disclosure clearer and easier to be understood, specific embodiments of the present disclosure will be described hereinafter.
By reading the following detailed description of preferred embodiments, various other advantages and benefits will become clear to those ordinary skilled in the art. Drawings are only used for the purpose to illustrate the preferred embodiments, and are not to be considered as the limitation of the present disclosure. And throughout the drawings, the same components are represented by the same reference numeral. In the drawings:
Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the drawings show the exemplary embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and a full conveying of the scope of the present disclosure to those skilled in the art.
Step S101: obtaining an image of a current page based on an instruction of screenshotting the current page
The instruction of screenshotting the current page may be initiated by a user performing a screenshot operation, or may also be automatically initiated by a terminal according to a current requirement, for example, if the user clicks a share page button, the terminal automatically initiates the instruction of screenshotting the current page, to obtain an image of a current page.
Specifically, the screenshot operation will be performed on the current page based on the instruction of screenshotting a current page, to obtain an image of the current page. The instruction of screenshotting a current page may be an instruction to take a screenshot image of the entire current page, or an instruction to take a screenshot image of a partial area of the current page, which is not specifically limited by the present disclosure.
Step S102: determining whether the image comprises content to be removed; if yes, step S103 will be performed; otherwise, the present method ends
Specifically, it is determined whether the image includes the content to be removed, wherein the content to be removed is the content that does not need to be displayed in the image. And the present disclosure does not specifically limit the manner of determining in this step. In specific implementation, those skilled in the art can make flexible determinations according to the contents of the image and at least one of page elements included in the current page as the source of the image.
Step S103: searching for a first element in a first image layer of the current page, the first element in the first image layer corresponding to the content to be removed and determining whether a second element exists in a second image layer based on a predetermined condition, wherein the second image layer is adjacent to the first image layer
The first element refers to an element in the current page which includes the content to be removed.
The purpose of the present disclosure is to hide displaying of the content to be removed. Specifically, according to position and hierarchical information (that is, information on the image layer where an element is located) of each element in the current page, positional relationship and hierarchical relationship between each element and the first element will be determined, and according to this then it will be determined whether a second element exists in the current page, so as to determine covering processing strategy for the content to be removed according to the result of the determination. The first element and the second element have the following relationship. First, hierarchical relationship; the second element is located in the second image layer that is adjacent to the first image layer, more specifically, the second element is located in a lower image layer of the first image layer. Second, positional relationship. A preset condition will be met between the second element and the first element, and the preset condition specifically refers to that, in a direction perpendicular to the current page, a perpendicular projection area of the first element is located within a range of perpendicular projection area of the second element. In other words, the second element is located in the lower image layer of the first image layer, and the second element completely “covers” the first element. It should be noted here that the “cover” here only refers to an inclusion relationship on the perpendicular projection area, and does not refer to the occlusion between image layers (for example, the upper image layer overlays the lower image layer).
For example, if the first element is located in an image layer above other image layer in which other element exists, and the first element is a rectangular picture located in the center of the screen, and the other element is another rectangular picture that is as large as the screen, it can be considered that the other element completely “covers” the first element.
Step S104: performing a covering processing on the image to cover the content to be removed to obtain a processed image based on a determination result
Specifically, the result of the determination includes existence of the second element or absence of the second element. When the second element exists, it can be determined that a complete covering of the content to be removed can be achieved by using that second element only, and when the second element does not exist, it can be determined that multiple elements in image layers under the first image layer are needed to achieve a complete covering of the content to be removed. On the basis of this, a covering processing will be performed according to the result of the determination to hide the content to be removed in the image.
In the method for processing a screenshot image provided according to the present embodiment, after an image of a current page is obtained, if it is determined that the image comprises content to be removed, a first element in the first image layer corresponding to the content to be removed is searched for in a current page; and then it is determined whether a second element exists in a second image layer based on a predetermined condition, and special hierarchical relationship and positional relationship between that second element and the first element enable to achieve complete covering of the content to be removed by only using that second element; on the basis of this, by performing a covering processing on the image to cover the content to be removed based on a determination result, the display of the content to be removed can be hidden. It can be thus seen that, in the solution of the present embodiment, after determining that the image comprises the content to be removed, by performing a covering processing on the image to cover the content to be removed to realize the hiding of the content to be removed, presenting of the content to be removed to the user can be avoided; and according to the results of determining whether a second element exists in the current page, a corresponding element is selected to perform the covering processing, instead of directly rearranging all the elements in the current page every time, which simplifies the processing flow and improves the processing effectiveness.
Step S201: obtaining an image of a current page based on an instruction of screenshotting the current page
Specifically, in response to the instruction of screenshotting the current page, a screenshot is taken according to the screenshot area specified in the instruction, and the image in the current page which corresponds to the screenshot area, is obtained. For example, the image corresponding to the complete current page is obtained.
Step S202: determining whether the image comprises content to be removed; If yes, step S203 will be performed; otherwise, the present method ends.
The content to be removed is the content that does not need to be displayed in the image. Optionally, the content to be removed is the content corresponding to an operable control in the current page. In the image obtained by screenshotting the current page, a user cannot perform any operation on a control displayed in the image, thus a corresponding control in the image is determined as the content to be removed. In a specific embodiment, the content to be removed is movable content in the current page. Optionally, the movable content is a playback progress bar, such as a playback progress bar for audio, video and other contents.
Specifically, a list of the content to be removed can be preset before the solution of the present embodiment is implemented. In the current page as the source of the image, each page element included in the screenshot area of the current page is matched with the list of the content to be removed. If there is a page element that is successfully matched, it is determined that the image includes the content to be removed, which indicates that there is the content to be removed that need to be hidden, and step S203 will be performed to take measures to hide the display; if there is not a page element that is successfully matched, it indicates that there is no content in the image the display of which needs to be hidden, and the present method ends.
The step S203: searching for a first element in a first image layer of the current page, the first element in the first image layer corresponding to the content to be removed
The first element found in the current page is the element that is successfully matched.
Step S204: determining whether a second element exists in a second image layer based on a predetermined condition, wherein the second image layer is adjacent to the first image layer, and wherein the predetermined condition comprises in a direction perpendicular to the current page, a perpendicular projection area of the first element in the first image layer is located within a perpendicular projection area of the second element in the second image layer; if yes, step S205 will be performed; otherwise, step S208 will be performed.
In the current page, from a visual perspective, part of the element contents of the second element is obscured by the first element, and at the same time, the corresponding area of the first element is included within a range of the corresponding area of the second element.
Specifically, first, position and hierarchical information of each element will be obtained by querying page layout information of the current page; then the hierarchical information of each element will be compared with the hierarchical information of the first element, and according to the result of the comparison, it will be determined whether a corresponding element is located in an image layer under and adjacent to the first image layer; and the position of each element will be compared with the position of the first element, and according to the result of the comparison, it will be determined whether the corresponding element completely “covers” the first element. When the results of the above two determination processes are both yes, then it is determined that a second element exists in the current page, and at this time, the step S205 will be executed to perform covering processing according to the second element; and when not both results of the above two determinations processes are yes, then it is determined that the second element does not exist in the current page, and at this time, the step S208 will be executed to performing covering according to multiple elements related to the first element.
Step S205: in response to determining that the second element in the second image layer exists, determining whether a third element exists in a third image layer, wherein the third image layer is located above the second image layer, and wherein the third element and the second element have an overlapping area in the direction perpendicular to the current page; if not, step S206 will be performed, and if yes, step S207 will be performed.
Specifically, when it is determined that a second element exists in the current page, then it indicates that the covering of the content to be removed can be achieved by only using that second element. At the same time, the overlay between image layers will cause obscuration between the corresponding page elements, wherein the upper element will obscure the lower element that has an overlapping area with the upper element. For example, the element 32 in
Further, when it is determined that the third picture element does not exist, the step S206 will be executed to perform covering processing by only using the second element; when it is determined that the third element exists, the step S207 will be executed to perform covering processing by using the second element and the third element, so as to ensure the integrity of the information conveyed by the image.
Step S206: in response to determining that the third element in the third image layer does not exist, covering a corresponding portion of the image using the second element based on position information of the second element to obtain the processed image
Specifically, if it is determined that the third element does not exist (
By exemplifying
Through this step, the content to be removed in the screenshot image can be covered by only using the second element, to hide the display of the content to be removed, and there is no need to use multiple elements for covering processing, which makes the procedure of the processing easier and more efficient.
Step S207: in response to determining that the third element in the third image layer exists, performing the covering processing on the image based on hierarchical information of the first image layer and the third image layer to obtain the processed image
Specifically, if it is determined that a third element exists (
Further, since the second element is located in the image layer under and adjacent to the image layer where the first element is located and the third element is located in an image layer above the image layer where the second element is located, the hierarchical information of the first element and the third element is specifically that, the third element is located in an image layer above the image layer where the first element is located, or the third element and the first element belong to the same image layer. Correspondingly, the procedure of the covering processing is specifically as follows: when the third element is located in an image layer above the image layer where the first element is located, or the third element and the first element belong to the same image layer, first, according to the position of the second element, the corresponding position of the screenshot image is covered by using the second element, that is, first, the covering processing is performed on the content to be removed by using the second element located in the lower image layer, so as to complete the obscuration of the content to be removed and hide the display of the content to be removed; then, according to the position of the third element, the corresponding position above the second element is covered by using the third element to obtain the processed image, that is: on the basis of obscuration of the content to be removed, the second element in the screenshot image is covered by other contents that need to be displayed, which are obscured by the second element, so as to enable the information conveyed in the finally obtained image consistent with the information conveyed by the current page.
By exemplifying
Through the present step, after the covering processing is performed on the content to be removed in the image by using the second element, the covering processing can be further performed by using the third element to ensure the integrity of the information conveyed by the image.
The above described steps S205 to S207 are all descriptions of the covering processing performed for the case where a second element that completely “covers” the first element exists in the current page. The following steps S208 to S209 are description of the covering processing performed for the case that no second element exists in the current page.
Step S208: in response to determining that the second element in the second image layer does not exist, determining that at least one fourth element exists in at least one fourth image layer of the current page, wherein the at least one fourth element has an overlapping area with the first element in the direction perpendicular to the current page, and wherein the at least one fourth image layer is not a bottom image layer
Specifically, when it is determined that second element does not exist, that is, an element that can completely “cover” the first element does not exist in the image layer adjacent to the image layer where the first element is located, then an element (that is, at least one fourth element) related to the first element needs to be determined in the current page, so as to hide the display of the content to be removed by using the related element. And in order to enable the complete hiding of the display of the content to be removed after the covering processing, the related element will be determined in a following way: starting from the image layer which is under and adjacent to the image layer where the first element is located, the element of each image layer is searched for sequentially from the upper to the lower, and the search will not be stopped until at least one element that is found meet a preset termination condition, and the at least one element when the search is stopped will be determined as the at least one fourth element; wherein the preset termination condition is that: in the direction perpendicular to the page, the perpendicular projection area of the first element is located within the perpendicular projection area of the at least one fourth element.
In addition, the bottom image layer of the page is usually a background image layer. Generally speaking, in the process of searching for at least one fourth image layer, the bottom image layer is not found when the preset termination condition is met. Correspondingly, in some alternative embodiments, the at least one fourth element is not a bottom image layer.
Through the present step, at least one fourth element can be determined. Because the at least one first element is an element which is searched for from the upper to the lower in accordance with the image layer information and which is found by stopping the search when a preset termination condition is met, the at least one fourth element is usually only part of the elements in the current page, rather than all of the elements.
Step S209: sequentially covering a corresponding portion of the image using the at least one fourth element in an order from a lower layer to an upper layer based on position information of the at least one fourth element and hierarchical information of the at least one fourth image layer to obtain the processed image
Specifically, in accordance with the hierarchy information of the at least one fourth element, the fourth element is selected sequentially in an order from the lower to the upper; and the selected fourth element is covered into the image according to its position in the current page to obtain the processed image.
By exemplifying
Through the present step, covering is performed by using at least one fourth element to complete the complete obscuration of the content to be removed; at the same time, the at least one fourth element is usually only a part of the elements of the current page, instead of all of the elements, which can reduce the amount of data processing for covering processing; moreover, the covering processing is performed from the lower to the upper in accordance with the hierarchical information, so that the processed image can convey accurate information; in addition, all of the elements that are found when the preset termination condition is met, are determined as the at least one fourth element, which in turn can avoid the problem of missing information in the processed image.
According to the method for processing a screenshot image provided by the present embodiment, the corresponding covering processing strategy will be determined according to the different results of determination whether a second element exists in the current page. When a second element exists in the current page, it needs to further determine whether a third element exists in the current page according to the overlap between the second element and other elements. If the third element does not exist, the covering processing will be performed by only using the second element, and the obscuration of the content to be removed in the screenshot image can be completed; if a third element exists, the covering processing needs to be performed by using the third element and the second element, to ensure the integrity of the information conveyed by the image while completing the obscuration of the content to be removed; when the second element does not exist in the current page, at least one fourth element is determined and used to perform the covering processing to complete the obscuration of the content to be removed and at the same time to ensure the integrity and accuracy of the information conveyed by the image. It can thus be seen that in the solution of the present embodiment, the obscuration of the content to be removed can be completed by only using a part of the elements to achieve the purpose of hiding of the display of the content to be removed; at the same time, compared to the way of rearranging all elements, the processing efficiency of the solution of the present embodiment is higher; and in the solution of the present embodiment, the integrity and accuracy of the information conveyed by the image are also ensured while the obscuration of the content to be removed is completed.

In the claims, any reference numbers placed between parentheses should not be constructed as a limitation to the claims. The word “comprising” does not exclude the presence of elements or steps not listed in the claims. The word “a” or “an” preceding an element does not exclude the presence of multiple such elements. The present disclosure can be realized by means of hardware including several different elements and by means of a suitably programmed computer. In the unit claims enumerating several devices, several of these devices may be embodied in the same hardware item. The use of the words first, second, and third, etc. do not indicate any order.
