It can be understood that, in an embodiment, the Base64 string-to-picture interface encodes the link string into a byte array by using a Base64 decoding method, the Base64 decoding method is a method for transmitting 8Bit byte codes, and then outputs the encoded byte array into a picture in a two-dimensional code format by using a FileOutputStream class, thereby obtaining the image code.

The steps obtain the two-dimensional code information in the visual picture report, and the synthesis process of the initial image is described below.

Step S130: and carrying out first image synthesis processing according to the preset base pattern template and the initial image to obtain a first drawing image.

In an embodiment, a plurality of base pattern templates can form a base pattern template database and be stored in a server, and the mobile terminal sends a request for obtaining the base pattern templates to the server according to the synthesis requirement of the visualization package, so that corresponding base pattern templates in the base pattern template database are obtained, and the next image synthesis is performed. It will be appreciated that the base pattern template database may also be stored in the mobile terminal, and the mobile terminal may directly retrieve the corresponding base pattern template from the memory.

In one embodiment, the base template database is stored as a resource file of the iOS system, for example in an installation package of program software for generating visual paintings. In general, the installation package includes executable binary files, picture, audio and other resource files, and when the installation package of relevant software of the iOS is downloaded, the resource files are downloaded to the mobile terminal. Therefore, in one embodiment, clicking the program software for generating the visual poster starts the APP, and at this time, the executable binary file is loaded into the memory, and at the same time, the resource files such as the picture, the audio and the like are stored back in the disk.

In an embodiment, referring to fig. 5, which is a flowchart showing a specific implementation of step S130, in this embodiment, the step of obtaining a base map template and performing a first image synthesis process with an initial image to obtain a first report image includes:

step S131: the image size and image color style of the initial image are obtained.

Step S132: and obtaining a base map template from a preset resource file according to the image size and the image color style.

In one embodiment, the initial image is an image used for promotion in a visual poster, such as a product image or a background image of the poster to be promoted, etc. The original image color style requires adaptation to the base pattern template because the base pattern templates for different original image sizes are different and for aesthetic reasons.

In an embodiment, the base pattern template includes a first preset area for placing the initial image, and in fig. 6a to 6c, the first preset area is indicated by a dashed box. Referring to fig. 6a, the image size of the initial image is smaller compared to the size of the first preset area in the base template 1, and thus the initial image and the base template 1 are not adapted. Referring to fig. 6b, the image size of the initial image exceeds the first preset area of the base template 2, and thus the initial image and the base template 2 are not adapted. Referring to fig. 6c, the image size of the initial image is just adapted to the first preset area of the base pattern template 3. Referring to fig. 6 a-6 c, the base template 3 is the base template that needs to be selected for this initial image.

In the above embodiment, the size relation between each base pattern template and the first preset area thereof is stored in the base pattern template database, and after the image size of the initial image is obtained, a suitable base pattern template is selected in the base pattern template database according to the image size. It will be appreciated that the selection criteria may include two points: 1) The initial image can be completely displayed in a first preset area in the base map template; 2) The distance between the upper, lower, left and right edge lines of the initial image and the upper, lower, left and right edge lines of the first preset area is smaller than the corresponding preset distance.

Referring to fig. 6c, a distance d1 between a top line of the initial image and a top line of the first preset area is smaller than the top line preset distance c1; the distance d2 between the lower edge line of the initial image and the lower edge line of the first preset area is smaller than the preset distance c2 of the lower edge line; the distance d3 between the left line of the initial image and the left line of the first preset area is smaller than the preset distance c3 between the left line and the left line; the distance d4 between the right line of the initial image and the right line of the first preset area is smaller than the preset distance c4 between the right line and the right line. It will be appreciated that c1, c2, c3 and c4 may be different or the same, as desired.

In an embodiment, the image color style of the initial image may be obtained, and the initial image may be subjected to color style classification according to a preset style classification rule, for example, different color styles of red, green, yellow, blue or violet. Correspondingly, the base pattern templates are subjected to color style division according to the same preset style division rules, each base pattern template and the color style thereof are stored in a base pattern template database, and after the image color style of the initial image is acquired, the appropriate base pattern template is selected in the base pattern template database according to the image color style.

In an embodiment, the color of each pixel of the initial image is counted, the duty ratio of the pixel of each color in the whole pixel is obtained, and the color system corresponding to the color with the largest duty ratio is selected to obtain the color style of the initial image.

It can be understood that the base pattern templates of the same color system can be selected according to the image color style of the initial image, for example, the base pattern templates of the red color system can be selected, and the base pattern templates of the complementary color system can be selected, for example, the initial image is of the green color system, and the base pattern templates are of the red color system, so as to realize the color bumping effect. The manner of color style selection is not limited in this embodiment.

Step S133: and synthesizing the initial image in a first preset area to obtain a first pictorial image.

In an embodiment, after the above process obtains the base image template from the preset resource file according to the image size and the image color style of the initial image, the initial image is synthesized in the first preset area of the base image template, so as to obtain the base image template including the initial image as the first drawing image.

After the first poster image is obtained, masking operation is needed by the following steps to improve the attractiveness of the visual poster.

Step S140: and generating a mask image according to a preset masking rule.

In an embodiment, the mobile terminal may obtain the preset masking rule from the server, or the preset masking rule is stored in a resource file of program software of the mobile terminal for generating the visual sketch, or stored in a memory space of the mobile terminal itself.

In one embodiment, the predetermined masking rules include a predetermined mask size rule and a predetermined mask transparency. The mask size rule is preset to limit the size of the mask image, and the mask transparency is preset to limit the transparency information of different areas in the mask image.

In an embodiment, referring to fig. 7, which is a flowchart showing a specific implementation of step S140, the step of obtaining a preset masking rule and generating a mask image according to the preset masking rule in this embodiment includes:

step S141: and acquiring first size information of the first pictorial image.

In one embodiment, the first size information of the first poster image includes: and acquiring the first height information and the first width information, namely acquiring the height and the width of the first poster image, and generating a proper mask layer according to the height and the width of the first poster image.

Step S142: and generating the mask height of the mask image according to the preset mask size rule and the first height information.

Step S143: and generating the mask width of the mask image according to the preset mask size rule and the first width information.

In an embodiment, referring to fig. 8, according to a preset mask size rule, a mask width of the mask image may be set to be consistent with the first width information of the first poster image, and a mask height of the mask image may be set according to the first height information of the first poster image. For example, the mask width of the mask image and the first width information of the first poster image are set to x1, the mask height of the mask image starts at 1/4 of the height of the first poster image, and the mask height of the mask image is set to h, which is 3/4 of the first height information h1, to the bottom of the first poster image.

Step S144: generating mask image transparency according to the preset mask transparency.

In one embodiment, to enhance the masking effect of the mask, different transparency is set at different positions of the mask image.

For example, referring to FIG. 9, in one embodiment, the mask height is divided into three regions, the first region being the top of the mask image to a 1/3 mask height position; the second area is from 1/3 mask height position to 2/3 mask height position; the third area is the 2/3 mask height position to the bottom of the mask image.
