Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present application provides a method for displaying a document including a multicolor picture, including the following steps:
s1, acquiring a designated file, wherein the designated file comprises a designated link, the designated link is linked to the first multicolor picture, and the designated file can only display a single-color picture;
s2, acquiring the first multicolor picture through the designated link;
s3, selecting a second multicolor picture from a preset standard multicolor picture library according to a preset picture screening method, wherein the second multicolor picture is associated with a designated multicolor display scheme, and the designated multicolor display scheme refers to a scheme of overlapping and simultaneously displaying a plurality of pre-stored designated single-color pictures;
s4, calculating the similarity degree value of the first multicolor picture and the second multicolor picture, and judging whether the similarity degree value is larger than a preset similarity degree threshold value;
s5, if the similarity value is not larger than a preset similarity threshold value, performing picture segmentation processing on the first multicolor picture to obtain the shapes of n single-color blocks and the positions of the single-color blocks in the first multicolor picture, wherein n is an integer greater than or equal to 2;
s6, generating n single-color sub-pictures according to a preset sub-picture generation method, wherein the size of all single-color sub-pictures is the same as that of the first multicolor picture, the color of the kth single-color sub-picture is the same as that of the kth single-color block, the shape and the position of a coloring area of the kth single-color sub-picture are the same as those of the kth single-color block, and k is an integer greater than 0 and less than or equal to n;
s7, deleting the designated link in the designated file, and filling a vacancy left after deletion in a mode of overlapping the n monochromatic sub-pictures, wherein the n monochromatic sub-pictures are set to be displayed simultaneously;
and S8, displaying the specified file.
As described in the above step S1, a specific file is obtained, wherein the specific file includes a specific link, the specific link is linked to the first multicolor picture, and the specific file can only display a monochrome picture. Since the given document can only display a monochrome picture, the conventional method cannot display the first multicolor picture, and the present application aims to solve such a technical problem. The monochrome picture refers to a picture formed by one color, and a transparent area is arranged outside an area covered by the color. The multicolor picture refers to a picture composed of a plurality of colors.
As described in the above step S2, the first multicolor picture is acquired through the designated link. Since the designated document cannot show the multicolor pictures, the first multicolor picture is linked to the designated document in a designated linking manner. The first multicolor picture is a picture to be displayed, so that the display effect finally realized by the application can be the same as that of the first multicolor picture.
As described in the above step S3, according to the preset picture screening method, a second multicolor picture is selected from the preset standard multicolor picture library, wherein the second multicolor picture is associated with a designated multicolor display scheme, and the designated multicolor display scheme refers to a scheme of overlapping and simultaneously displaying a plurality of pre-stored designated single-color pictures. The standard multicolor pictures are pre-stored in the standard multicolor picture library and respectively correspond to different color display schemes, and if the first multicolor picture is the same as or similar to the second multicolor picture, the corresponding color display scheme is directly adopted to display the file. The preset picture screening method includes, for example: acquiring the types of all colors of the first multicolor picture, and judging whether a first intermediate picture exists in a preset standard multicolor picture library, wherein the types of all colors of the first intermediate picture are the same as the types of all colors of the first multicolor picture; if a first intermediate picture does not exist in a preset standard multicolor picture library, judging whether a second intermediate picture exists in the standard multicolor picture library, wherein the types of colors displayed by all colors of the second intermediate picture after being superposed through specified colors are the same as the types of all colors of the first multicolor picture; and if a second intermediate picture exists in the standard multicolor picture library, acquiring the second intermediate picture and recording as a second multicolor picture.
As described in step S4, the similarity value between the first multicolor picture and the second multicolor picture is calculated, and whether the similarity value is greater than a preset similarity threshold is determined. The similarity value is used to measure whether the first multicoloured picture and the second multicoloured picture are identical. The way of calculating the similarity value of the first multi-color picture and the second multi-color picture is, for example: acquiring a plurality of first boundary lines between different color regions in the first multicolor picture and acquiring a plurality of second boundary lines between different color regions in the second multicolor picture; acquiring a first total length of the first interface lines and acquiring a second total length of the second interface lines; according to the formula: and calculating the similarity value of the first multicolor picture and the second multicolor picture according to the similarity value of 1/| the first total length-the second total length |.
As described in step S5, if the similarity value is not greater than the preset similarity threshold, performing picture segmentation on the first multicolor picture to obtain the shapes of n single-color blocks and the positions of the single-color blocks in the first multicolor picture, where n is an integer greater than or equal to 2. If the similarity value is not greater than the preset similarity threshold, it indicates that no existing color display scheme exists, and therefore, an appropriate color display scheme needs to be generated immediately. The mode of performing picture segmentation processing on the first multi-color picture is, for example: performing a first grid splitting process on the first polychrome picture, thereby splitting the first polychrome picture into a plurality of first squares, and dividing the plurality of first squares into first single-color squares and first polychrome squares; performing second grid segmentation processing on the first multi-color square blocks to obtain a plurality of second square blocks, wherein the area of the second square blocks is smaller than that of the first square blocks, dividing the plurality of second square blocks into second single-color square blocks and second multi-color square blocks, and setting the second multi-color square blocks to be transparent; and combining adjacent homochromatic squares to obtain n monochromatic blocks, and acquiring the shapes of the n monochromatic blocks and the positions of the monochromatic blocks in the first multicolor picture, wherein n is an integer greater than or equal to 2.
As described in step S6 above, according to the preset sub-picture generation method, n single-color sub-pictures are generated, where all the single-color sub-pictures have the same size as the first multi-color picture, the color of the kth single-color sub-picture is the same as the color of the kth single-color block, the shape and position of the coloring region of the kth single-color sub-picture are the same as the shape and position of the kth single-color block, and k is an integer greater than 0 and less than or equal to n. Although the designated file cannot show multicolor pictures, the designated file can show a plurality of single-color pictures, and the single-color pictures are displayed in an overlapping mode, so that the multicolor display is realized in terms of visual effect. Hereby, n monochromatic sub-pictures are generated, wherein all monochromatic sub-pictures have the same size as the first polychrome picture, the color of the kth monochromatic sub-picture is the same as the color of the kth monochromatic block, and the shape and position of the colored area of the kth monochromatic sub-picture is the same as the shape and position of the kth monochromatic block.
As described in the above step S7, the designated link is deleted from the designated file, and the empty space left after deletion is filled up by superimposing the n monochrome sub-pictures, where the n monochrome sub-pictures are set to be displayed simultaneously. And deleting the appointed link and filling a vacant position left after deletion in a mode of overlapping the n monochromatic sub-pictures because the proper n monochromatic sub-pictures are obtained, so that when the appointed file is displayed, the n monochromatic sub-pictures are displayed simultaneously, and the multi-color display is realized.
As described in the above step S8, the specified file is presented. And deleting the designated link and filling up the vacant positions left after deletion by overlapping the n single-color sub-pictures to obtain the designated file, wherein the display effect is the same as the display effect of the first multi-color picture, so that the multi-color display is completed on the basis of not changing the file architecture.
In one embodiment, the step S3 of selecting the second multi-color picture from the predetermined standard multi-color picture library according to the predetermined picture screening method includes:
s301, acquiring the types of all colors of the first multicolor picture, and judging whether a first intermediate picture exists in a preset standard multicolor picture library, wherein the types of all colors of the first intermediate picture are the same as the types of all colors of the first multicolor picture;
s302, if a first intermediate picture does not exist in a preset standard multicolor picture library, judging whether a second intermediate picture exists in the standard multicolor picture library, wherein the types of colors displayed by all colors of the second intermediate picture after being superposed through specified colors are the same as the types of all colors of the first multicolor picture;
and S303, if a second intermediate picture exists in the standard multicolor picture library, acquiring the second intermediate picture, performing superposition processing on all coloring areas in the second intermediate picture by adopting specified colors, and recording the superposed second intermediate picture as a second multicolor picture.
As described above, selection of a second multi-color picture from a pre-set library of standard multi-color pictures is achieved. The second multicolor picture is associated with a designated multicolor display scheme, which refers to a scheme of overlapping and simultaneously displaying a plurality of pre-stored single-color pictures, so that if it can be determined that the second multicolor picture is similar to or the same as the first multicolor picture, the designated multicolor display scheme is adopted. In order to find out the second multicolor picture which is the most similar, the method comprises the steps of obtaining all color types of the first multicolor picture, and judging whether a first intermediate picture exists in a preset standard multicolor picture library, wherein all color types of the first intermediate picture are the same as all color types of the first multicolor picture; if the first intermediate picture does not exist in the preset standard multicolor picture library, judging whether a second intermediate picture exists in the standard multicolor picture library, wherein the types of the colors displayed by the superposition of all the colors of the second intermediate picture through the same color are the same as the types of all the colors of the first multicolor picture; and if a second intermediate picture exists in the standard multicolor picture library, acquiring the second intermediate picture, performing superposition processing on all coloring areas in the second intermediate picture by adopting specified colors, and marking the superposed second intermediate picture as a second multicolor picture so as to enable the preliminarily screened second multicolor picture to be similar to the first multicolor picture as much as possible.

As described above, calculating a similarity value of the first polychrome picture and the second polychrome picture is achieved. The total length of the boundary line is used as a calculation basis of the similarity degree value. Specifically, a first total length of the first boundary lines and a second total length of the second boundary lines are obtained, and according to a formula: and calculating the similarity value of the first multicolor picture and the second multicolor picture according to the similarity value of 1/| the first total length-the second total length |. Generally, only the total lengths of the boundary lines of similar pictures are substantially the same. If the first total length and the second total length are approximately equal, the similarity degree value is approximately infinite, which indicates that the first multicolor picture and the second multicolor picture are similar.
In one embodiment, the step S4 of calculating the similarity value of the first multicolor picture and the second multicolor picture comprises:
