Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method for storing a document, which is applied to a terminal capable of reading the document. The terminals to which the method can be applied include mobile terminals and non-mobile terminals.
The method for storing documents provided in the embodiments of the present application will be described in detail below with reference to specific embodiments, as shown in fig. 1, the specific steps are as follows:
In the embodiment of the application, the electronic device can acquire the target document to be stored. The electronic device may obtain the target document in a wireless data transmission manner, for example, the electronic device may download a certain document from a network as the target document to be stored; alternatively, the electronic device may acquire the target document by wired data transmission such as USB or data line. The target document may be an electronic document, such as a PDF document. The target document may include a plurality of images, and may also include other data such as text, tables, and the like, which is not limited in this embodiment of the application.
In the embodiment of the present application, the preset identification rule is used to determine whether there is an overlapping region in the plurality of images, and as long as the function of determining whether there is an overlapping region in the plurality of images can be implemented, the preset identification rule may be used in the embodiment of the present application.
Optionally, according to a preset identification rule, the electronic device divides the plurality of images into at least one image group, and an overlapping portion exists between any one image in the image group and at least one image in other images in the image group, and a specific processing procedure may be as follows:
step one, determining the data size, the dimension and the position information in the target document of all images in the target document page.
In the embodiment of the application, the electronic equipment determines the data size, the size and the position information in the target document of all the images in the target document page. The size of the data volume is the size of a storage space occupied by the image, the size of the size may include a length and a width, the length and the width are parameters using pixels as units, and the position information includes a page index of the image and a relative position in a page.
And step two, judging whether any one of the images has an overlapping part with at least one of the other images in the images according to the position information and the size of the images in the target document.
In the embodiment of the application, the electronic equipment judges whether an overlapping area exists between two images according to the size of the images and the position information in the target document. The electronic equipment recognizes the images by taking a page as a unit, judges whether the image and other images have an overlapping area or not by starting from the first image of the first page, and judges that the two images have the overlapping area when the two images are tangent or intersected. When any one of the images has an overlapping part with at least one of the other images in the images, the images are divided into an image group, and any one of the images in the image group should have at least one overlapping area with one or more other images in the same group. As shown in fig. 2, fig. 2 illustrates a schematic diagram of an image group in an electronic device, which includes an image 201, an image 202, and an image 203. The image 201 and the image 202 have an overlapping area, and the image 202 and the image 203 have an overlapping area, so that the electronic device divides the image 201, the image 202 and the image 203 into an image group.
If the first image of the first page does not have an overlapping area with other images, judging whether the second image of the first page has an overlapping area with other images except the first image of the first page, and if so, dividing the first image of the first page and other images into an image group.
The electronic equipment continuously judges whether the images in the image group and the images outside the image group have overlapping areas or not, if so, the images outside the image group and the images in the image group having overlapping areas are drawn into the image group and continuously judged until the images in the image group and the images outside the image group do not have overlapping areas, and if not, the image group is reserved and the next image outside the image group is continuously judged until all the images of the page are judged.
And step three, if any image in the plurality of images and other images in the plurality of images do not have overlapped parts, judging that the plurality of images do not form the image group.
In the embodiment of the application, the area occupied by the image is determined by the relative area occupied by the image in the target document and the relative position of the image in the document, the areas can be overlapped, and when the areas occupied by the plurality of images do not have the overlapped area, the situation that the plurality of images do not overlap with each other is judged, namely the plurality of images do not form an image group.
And step four, if any image in the plurality of images has an overlapping part with at least one image in other images in the plurality of images, judging that the plurality of images form an image group.
In the embodiment of the application, the area occupied by the image is determined by the relative area occupied by the image in the target document and the relative position of the image in the document, the areas occupied by different images can be mutually overlapped, and when an overlapping part exists between any one of the images and at least one of the other images in the images, the situation that the images are mutually overlapped (namely, one image in the image group can be overlapped with one or more of the other images in the image group) is judged, namely, the images form the image group.
And step five, dividing the images with the overlapped areas in the target document into the same image group to obtain at least one image group.
In the embodiment of the application, the electronic equipment divides the images with the overlapped areas in the target document into the same image group, and in the same image group, any one image and at least one image in other images in the image group have overlapped parts. After obtaining the image group, the electronic device will prepare to merge the images within the image group.
And 103, carrying out image combination processing on the images contained in the image group to obtain a combined image corresponding to each image group.
In the embodiment of the application, after obtaining the image group, the electronic device performs merging processing on images in the image group, and the merging processing is performed in a superposition manner. The electronic device superimposes all the images in the image group together in sequence to generate a new image, wherein the image is called a combined image, the combined image is an image, and the displayed content is consistent with the content displayed in the image group.
Optionally, the electronic device performs image merging processing on each image included in the image group, and the specific processing procedure may be as follows:
step one, a blank image is created at the position of the image group.
In the embodiment of the application, the electronic device creates a blank image at the position of the image group, determines four pixel points of the top, bottom, left and right of the original position of the image in the image group, and uses the four pixel points as four boundary points of the blank image to form the boundary of the blank image, so that the merged image does not affect other contents in the target document and the contents of the merged image.
And step two, pasting the images into blank images according to the display sequence of the images in the image group and the relative positions of the images to obtain combined images.
In this embodiment of the application, the electronic device pastes an image into a blank image according to the display sequence of the images in the image group and the relative position between the images, and merges the blank image and the image in the blank image into one image to obtain a merged image, as shown in fig. 3, fig. 3 shows a schematic diagram of a merged image in the electronic device, where the schematic diagram includes an image 204. The image 204 is a merged image obtained by merging the images 201, 202, and 203 in fig. 2. At this time, both the image group and the combined image exist in the target document.
And step three, comparing the total data volume of all the images in the image group with the data volume of a combined image obtained after the image group is combined and processed.
In the embodiment of the application, after the electronic device obtains the combined image, the data volume of the combined image can be obtained, the total data volume of the image group is the total data volume of all images in the image group, and the data volume of each image in the image group is summed by the electronic device to obtain the total data volume of the image group. The electronic equipment compares the total data volume of the image group with the data volume of the combined image, the comparison aims to delete the part with large data volume and reserve the part with small data volume, and the purpose of reducing the storage space occupied by the target document is achieved.
And step four, if the total data volume of the image group is larger than the data volume of the combined image, replacing the image group in the target document with the combined image.
In the embodiment of the application, after the electronic device obtains the merged image, the image group and the merged image generated by combining the image group are compared in the target document, and if the total data amount of the image group is larger than the data amount of the merged image, the image group is deleted, and the image group in the target document is replaced by the merged image.
And after the electronic equipment obtains the combined image, comparing the image group and the combined image generated by combining the image group in the target document, and if the total data volume of the image group is less than or equal to the data volume of the combined image, deleting the combined image and reserving the image group in the target document.
And 104, storing the document after the image combination processing.
In the embodiment of the application, the electronic equipment merges the images with the overlapped areas in the target document. When storing the document, the user can obtain a target document with smaller data size and unchanged content compared with the data size before storing. In the embodiment of the application, the final purpose of the method for using the stored document by the electronic device is to reduce the size of the storage space occupied by the target document on the basis of not changing the display of each image in the target document, so that after the method for storing the document is used, the display content of the document is the same as the display content before the method for using the stored document.
Optionally, an embodiment of the present application further provides a process for displaying a target document, which specifically includes the following steps:
step one, when a display instruction corresponding to the target document and input by a user is received, acquiring the combined image.
In the embodiment of the application, the image group and the combined image which are compared by the electronic equipment can be reserved on the side with small data amount, and the side with large data amount is deleted, so that only one combined image or image group can be reserved on the position of the image group when the document is displayed.
And step two, displaying the merged image at the corresponding position according to the position information of the plurality of images in the target document.
In the embodiment of the application, when the electronic equipment displays the target document, the image group is replaced by the merged image, and the number of images in the target document is reduced, so that the purpose of improving the analyzing and rendering speed when the document is opened is achieved while the data volume of the target document is reduced.
An example of a method for storing a document is also provided in the embodiments of the present application, and as shown in fig. 4, the example includes:
In step 404, the images with the overlapped area are divided into an image group.
Step 406 is executed to determine whether the data amount of the merged image is smaller than the data amount of the image group, and if the data amount of the merged image is smaller than the data amount of the image group, step 407 is executed, and if the data amount of the merged image is not smaller than the data amount of the image group, step 408 is executed.
In the embodiment of the application, the electronic device can acquire a target document to be stored, and the target document comprises a plurality of images. According to a preset identification rule, the electronic equipment can determine an image with an overlapped part in a plurality of images in the target document. The electronic equipment divides the images into an image group, and combines all the images in the image group to obtain a combined image. And the electronic equipment compares the total data volume of the image group with the data volume of the merged image, and if the total data volume of the image group is larger than the data volume of the merged image, the image group is deleted and the merged image is reserved, otherwise, the merged image is deleted and the image group is reserved.
