Background
With the rapid development of multimedia technology, a user can obtain more and more pictures from a network, but the pictures occupy more information resources relative to texts, so that a certain storage space is required for storing the pictures, therefore, when the pictures are loaded to a certain position of a webpage from the network, a occupied bitmap is required to be occupied before the pictures in the webpage are not loaded, and currently, a commonly used method for loading the occupied map mainly comprises the following two schemes.
1. The method is used for loading a known small picture at the picture position of the webpage.
The known picture with a small storage space is preloaded at the position where the image needs to be loaded in the webpage, for example, the known picture can be an identification picture of a website domain name symbol, and the original picture is displayed to a user after the original picture is loaded successfully.
The above-described prior art enables a user to determine that a picture is being loaded by providing the user with a known small picture, so that the user can expect the upcoming picture. However, the known small pictures are the same before all the pictures are loaded, which makes the interface of the web page monotonous and easily causes the user to lose interest and wait patience.
2. A method for loading a thumbnail corresponding to an original picture at a picture position of a webpage.
Before the original pictures are loaded, a thumbnail corresponding to the original pictures and occupying a small storage space is stored in advance, the thumbnail is displayed at the picture position in an amplification mode when the thumbnail is loaded, a user can know the original pictures which are being loaded in advance, and the original pictures are displayed to the user after the original pictures are loaded successfully. To further compress the storage space, the thumbnail may also be set to a black and white picture.
The above prior art can load the image preview of the original image to the user, so that the user can know the upcoming original image in advance. Although the thumbnail has been compressed compared to the original picture, the information of the content that needs to be loaded when loading the thumbnail is so large that the loading speed of the thumbnail is slow.

Detailed Description
The embodiment of the invention provides a loading processing method and device of an occupation bitmap, which are used for improving the loading speed of the occupation bitmap and meeting the requirement that a user knows an original picture needing to be loaded in advance.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one skilled in the art from the embodiments given herein are intended to be within the scope of the invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention and the above-described drawings are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
The following are detailed below.
Referring to fig. 1, the loading processing method provided in an embodiment of the present invention may include the following steps:
101. and acquiring the corresponding main tone of the picture needing to be loaded in a delayed manner.
In the embodiment of the invention, when the terminal loads the picture from the network, the picture usually needs to be loaded in a delayed manner because the picture occupies larger resources compared with the text. In the embodiment of the invention, the main tone corresponding to the picture needing to be loaded in a delayed manner is obtained, wherein the main tone corresponding to the picture is the main tone of the picture, the main tone refers to the main color attribute expressed in the color collocation of the picture, the main tone refers to the condition that which wavelength is dominant in the light reflected by the picture, different wavelengths generate different colors, and the main tone is the important characteristic of the colors of the picture. For example, the pictures to be loaded in a delayed manner adopt a Red Green Blue (RGB) color mode, and for different pictures, RGB, that is, intensities of three primary colors of Red, Green and Blue need to be respectively specified, in the RGB color mode, each color intensity is at least 0 and at most 255, and is usually identified by 16-system numerical values, for example, 255 corresponds to hexadecimal or FF, and the numerical values of the three RGB components are sequentially arranged to start with # to represent different colors, for example, a color value # FF0000 is Red. When the picture adopts the RGB color mode, for example, the corresponding dominant hue of the picture acquired in step 101 is RGB (76,125,158). It should be noted that, in the embodiment of the present invention, the color of the picture may also be implemented by using other color modes, for example, a YUV color mode, and the like, which is not limited herein.
It should be noted that, the dominant hue of the picture is mainly used for identifying the image by the computer technology at present, but in the embodiment of the present invention, the dominant hue of the picture is used in the loading process of the occupied bitmap, which can realize fast loading and meet the requirement of the user to know the picture in advance. In the embodiment of the present invention, there are multiple methods for calculating the dominant hue of the picture, where one of the methods is as follows, and the step 101 obtains the dominant hue corresponding to the picture that needs to be loaded with a delay, and specifically includes the following steps:
a1, obtaining a color disc according to the colors selected from the color plate database, wherein the color disc comprises multiple colors;
a2, receiving a color code of a main tone corresponding to a picture sent by a background server;
and A3, matching the color codes with the colors in the color disc, and determining the corresponding main tone of the picture according to the matching result.
In step a1, the palette database may be customized as needed, a plurality of colors that may be displayed are stored in the palette database, and a plurality of colors are selected from the palette database according to a pre-configured requirement and placed in one color wheel, so that the color wheel includes the selected plurality of colors. Such as 24 basic colors of a universal color wheel. After the color wheel is obtained, step a2 is executed, the terminal may receive, through the client, the color code of the keytone corresponding to the picture that needs to be delay loaded and is sent by the background server, that is, the keytone corresponding to the picture that needs to be delay loaded is calculated by the background server, after the keytone corresponding to the picture that needs to be delay loaded is calculated by the background server, the background server sends the color code of the keytone to the terminal, and then the terminal may receive the color code of the keytone sent by the background server. Next, step a3 is executed, the color code of the received dominant hue is used to match with the color in the color wheel, a matching result is generated, and what kind of color in the color wheel and the color code can be successfully matched is recorded in the matching result, so that the color in the color wheel which is successfully matched is the dominant hue corresponding to the picture which needs to be loaded with a delay time.
In the foregoing implementation manner, the terminal receives the color code of the main tone corresponding to the picture that needs to be loaded in a delayed manner through interaction with the background server, so that the main tone corresponding to the picture is obtained through the color palette. In another implementation manner of the present invention, the step 101 of obtaining the corresponding dominant hue of the picture that needs to be loaded with a delay may specifically include the following steps:
b1, dividing the picture needing to be loaded in a delayed mode into N sub-pictures, wherein N is a natural number larger than 1;
b2, respectively calculating the corresponding main tone of each sub-picture in the N sub-pictures to obtain N main tones corresponding to the N sub-pictures;
and B3, selecting one main tone with the largest number of sub pictures from the N main tones as the main tone corresponding to the picture.
The method includes the steps of obtaining a main tone corresponding to a picture, obtaining a main tone corresponding to the picture through a calculation mode, cutting the picture needing delay loading in step B1 to obtain N sub-pictures, wherein the sub-pictures can also be called mosaic tiles, executing step B2 to calculate the main tone corresponding to each sub-picture in the N sub-pictures respectively, obtaining the main tone corresponding to each sub-picture, namely obtaining the N main tones, traversing all the sub-pictures in step B3, counting the number of different main tones in the N main tones respectively, counting the number of sub-pictures in each main tone, and selecting the main tone with the largest number of sub-pictures as the main tone corresponding to the picture needing delay loading.
It should be noted that, in step B2, the dominant hue corresponding to each sub-picture needs to be calculated, and there are various methods for calculating the dominant hue of the sub-picture, for example, the average RGB value of all pixel points in the sub-picture may be calculated, and the color corresponding to the average RGB value is used as the color corresponding to the dominant hue of the sub-picture, and for example, the RGB values of all pixel points in the sub-picture may also be calculated, then the number of pixel points corresponding to different RGB values is counted, and the color corresponding to the RGB value with the largest number of pixel points is taken as the color corresponding to the dominant hue of the sub-picture.
Further, in the embodiment of steps B1 to B3 of the present invention, before the step B3 selects one dominant hue with the largest number of sub-pictures from the N dominant hues as the dominant hue corresponding to the pictures, the method for loading the occupancy map provided in the embodiment of the present invention may further include the following steps:
and B4, removing the M main tones with black or white colors from the N main tones to obtain (N-M) main tones, wherein M is a natural number smaller than N.
In an implementation scenario of performing step B4, step B3 selects one dominant hue with the largest number of sub-pictures from the N dominant hues as the dominant hue corresponding to the picture, and specifically includes the following steps:
and selecting one main tone with the largest number of sub-pictures from the (N-M) main tones as the main tone corresponding to the picture.
That is, after obtaining N keytones corresponding to the N sub-pictures in step B2, obtaining black and white keytones from the N keytones, if the number of the obtained black or white keytones is M, removing the black or white keytones from the N keytones, and counting the number of different keytones from the (N-M) keytones through all the sub-pictures except the black or white keytones, and then selecting one keytone with the largest number of sub-pictures as the keytone corresponding to the picture requiring time-lapse loading. It should be noted that, when step B4 is executed, the main tone of black or white in the sub-picture is removed from the N main tones, so that the main tone corresponding to the acquired picture that needs to be subjected to time-lapse loading may not be black or white, and of course, in the embodiment of the present invention, step B4 may not be executed, and the main tone corresponding to the acquired picture that needs to be subjected to time-lapse loading may also be black or white.
102. The color occupying the bitmap is set according to the dominant hue.
In the embodiment of the invention, after the main tone corresponding to the picture needing to be loaded in a delayed manner is acquired, the color of the occupation map is set according to the main tone corresponding to the picture, wherein the occupation map refers to the picture which is used for occupation before the picture in the webpage is not loaded. In the foregoing prior art, the occupation map used may be a known small picture (for example, a domain name identifier of a website) or a thumbnail corresponding to the original picture, whereas in the embodiment of the present invention, the occupation map is a color with a color value determined by a main color, and the color of the occupation map may be determined according to the main color, so that the occupation map may reflect the color attribute of the picture being loaded. Compared with the setting mode of the placeholder map in the prior art, the placeholder map in the embodiment of the invention is a picture with color attributes set according to the main tone, and the placeholder map in the embodiment of the invention can be shown only through the color values, and the color values generally only need to occupy a few bytes, namely information smaller than 0.01k, so that the placeholder map provided by the embodiment of the invention occupies a small storage space.
In some embodiments of the present invention, the step 102 of setting the color occupying the bitmap according to the dominant hue specifically includes the following steps:
and C1, setting the color of the occupation map as the first color corresponding to the dominant hue according to the dominant hue.
In the embodiment that step C1 is executed, after the dominant hue corresponding to the picture that needs to be delay loaded is obtained in the foregoing step, the terminal determines that the dominant hue corresponding to the picture that needs to be delay loaded is the first color, for example, if the picture that needs to be delay loaded is a picture of blue sky, and the first color corresponding to the dominant hue of the picture is obtained as blue, the color of the occupancy map may be set as the first color corresponding to the dominant hue in the embodiment of the present invention, that is, the color of the occupancy map may be set as blue. In the implementation scenario of step C1, the technique of identifying the dominant hue of the picture is used in the placeholder map for picture delay loading, and the dominant hue of the picture to be delay loaded can be used as the color of the placeholder map, and the color of the placeholder map is the same as the color of the picture to be delay loaded, so that the user can know the dominant hue of the picture in advance before the picture loading is completed, and not only can the curiosity of the user about the picture to be loaded be satisfied, but also the loading flow can be saved, and the color value for loading the dominant hue only needs to transmit a few bytes, which is less than 0.01K of data volume, so that the loading speed can be increased, and the loading flow can be saved.
In other embodiments of the present invention, the step 102 of setting the color of the occupation map according to the dominant hue specifically includes the following steps:
d1, correcting the first color corresponding to the main tone according to the preset color correction parameters to obtain a second color, and setting the color of the occupation bitmap as the second color obtained by correcting the first color.
In the embodiment that step D1 is executed, after the foregoing step acquires the dominant hue corresponding to the picture that needs to be subjected to time-lapse loading, the terminal side sets a set of color correction parameters in advance, for example, taking the picture as an RGB color mode as an example, the terminal side may set the color correction parameters in 3 components of RGB to be +2, for example, if the foregoing step acquires the first color corresponding to the dominant hue corresponding to the picture that needs to be subjected to time-lapse loading to be RGB (76,125,158), the first color is corrected according to the color correction parameters, and the obtained second color is RGB (76+2,125+2,158+2) ═ RGB (78,127,160). And after the second color is obtained, setting the color of the occupation bitmap as the second color. It should be noted that, unlike the implementation of the foregoing step C1, in step D1, the first color corresponding to the dominant hue of the picture is not directly used as the color of the bitmap in step D1, but the first color corresponding to the dominant hue of the picture is corrected to obtain the second color, and the second color obtained after the correction is the color of the bitmap. In the implementation scenario of step D1, the technique of identifying the dominant hue of the picture is used in the placeholder map for picture delayed loading, the first color corresponding to the dominant hue of the picture to be delayed loaded may be modified to serve as the color of the placeholder map, and the color of the placeholder map and the dominant hue of the picture to be delayed loaded have a direct association relationship, so that a user may know the color related to the dominant hue of the picture in advance before the picture is loaded, which may not only meet the curiosity of the user about the picture to be loaded, but also save the loading traffic, and the color value for loading the dominant hue only needs to transmit several bytes, which is less than 0.01K of data volume, thereby increasing the loading speed and saving the loading traffic.
In other embodiments of the present invention, the step 102 of setting the color of the occupation map according to the dominant hue specifically includes the following steps:
e1, obtaining a plurality of color discs selected from the color plate database, wherein each color disc in the plurality of color discs corresponds to one color;
e2, selecting a third color which is the same as or closest to the first color from the multiple color discs according to the first color corresponding to the main tone;
and E3, setting the color of the occupation map as a third color.
Step E1 is similar to step a1 in the foregoing embodiment, and the terminal may customize the color palette database as needed, store multiple colors that may be displayed in the color palette database, and select multiple colors from the color palette database according to the preconfigured requirements and place the multiple colors in one color wheel, where the color wheel includes the selected multiple colors. After the color wheel is defined in step E1, if the corresponding dominant hue of the picture that needs to be loaded in a delayed manner is the first color, matching the first color with the color in the color wheel, if the color wheel has the same color as the first color, the third color is a color completely equal to the color code of the first color, or if the color wheel does not have the same color as the first color, selecting the third color with the color closest to the first color from the color wheel. The third color whose color is closest to the first color may refer to a color code whose value of each component of the color code is closest to the first color, for example, a color code whose value of each component of the first color is closest in distance may be calculated as the third color, where the proximity degree of two close colors may be calculated by a euclidean distance, or may be realized by other distance algorithms.
103. And loading the occupation bitmap after the color setting is finished on the display position corresponding to the picture.
In the embodiment of the invention, in the process of loading the original picture, the occupied bitmap after the color setting is finished can be loaded, and the occupied bitmap with a certain color is displayed at the display position corresponding to the original picture, so that a user can see the color of the occupied bitmap before seeing the original picture in the process of waiting for the original picture to be loaded, the requirement of the user on knowing the picture in advance is met, in addition, the color of the occupied bitmap is displayed at the display position corresponding to the picture, and the color value of the color of the occupied bitmap can be finished only by occupying a few bytes, so that the loading speed of the occupied bitmap in the embodiment of the invention is very high.
As can be seen from the description of the embodiment of the present invention in the above embodiment, the dominant hue corresponding to the picture that needs to be loaded in a delayed manner is first obtained, then the color of the occupied bitmap is set according to the dominant hue, and finally the occupied bitmap after the color setting is completed is loaded at the display position corresponding to the picture. In the embodiment of the invention, the colors of the occupation bitmap can be set according to the main tone corresponding to the picture, so the occupation bitmap with the set colors can be loaded at the display position corresponding to the picture before the picture is loaded, so that no known thumbnail picture is displayed at the picture display position, and no thumbnail picture is displayed, but a colored occupying picture map is displayed, the color of the occupying bitmap is determined by the corresponding main tone of the picture being loaded, so that the occupying bitmap can reflect the color attribute of the picture being loaded, a user can see the color of the occupying bitmap before seeing the original picture, the requirement of the user on knowing the picture in advance is met, in addition, the colors of the occupying bitmap are displayed at the corresponding display positions of the pictures, the color values of the occupying bitmap can be completed only by occupying a plurality of bytes, therefore, compared with a mode of loading the thumbnail, the loading speed of loading the occupation bitmap in the embodiment of the invention is very high.
