In the prior art, when a picture is processed according to a specific area, a designer is required to observe the picture through human eyes and then manually zoom the picture. This results in low precision, high labor costs, and low efficiency of adjustment. To overcome the defects in the prior art, the present application provides a picture scaling processing scheme, which has the following main principles: and then, according to the scaling parameter to be adjusted, automatically carrying out scaling adjustment operation on the picture according to a specific requirement (reference value) so as to enable the scaling parameter to be adjusted of the picture to accord with the specific reference value. In an embodiment of the present invention, the attributes of the picture include, but are not limited to: pixel value, transparency, resolution, hue, saturation, brightness, etc. of the picture. The zoom parameter to be adjusted of the picture refers to an adjustment feature object obtained according to one or more of the above attributes of the picture and used for performing zoom adjustment on the picture, for example, a specific area of the picture (a visual area, a portrait area, etc. of the picture). When the zoom parameter to be adjusted of the picture is the visual area, the zoom parameter can be obtained by using the pixel value and the transparency value of each pixel point in the picture. Fig. 1 is a schematic diagram of a picture scaling processing method according to an embodiment of the present invention. As shown in fig. 1, for example, it is assumed that a specific application scenario is to adjust the pictures (a), (b), and (c) to be pictures that look the same, that is, to make the visual areas of the three adjusted pictures equal. Wherein, the picture (a) is a rectangular picture, and the colored pattern in the picture is filled in the whole picture (namely, no white or transparent color area exists in the picture); the picture (b) is a square picture, and the colored pattern in the picture is a circle with the diameter equal to the side length of the square (the area outside the circle is white or transparent); the picture (c) is a rectangular picture, and the colored pattern in the picture is a cross-shaped pattern (the area outside the cross shape is white or transparent). According to the scheme of the present invention, the RGB value or RGBA value of each pixel point in the three pictures is respectively identified, and the areas of the areas outside the white (e.g., pixel point with pixel value # fff) area and the full-transparent area in the pictures (i.e., the rectangular area in the picture (a), the circular area in the picture (b), and the cross area in the picture (c)) are counted and respectively determined as the scaling parameters (i.e., the visual areas) to be adjusted for the pictures (a), (b), and (c). And then, adjusting the size of the pictures to be processed one by one or in batches according to a preset reference value or a reference value calculated in real time. It is assumed that the visual area of the picture (c) is determined to be the smallest by calculation, and is determined as a reference value. The visual area of the picture is accurately determined through the attribute of the pixel point in each picture, and the picture can be automatically zoomed and adjusted according to specific requirements (the reference value), so that the defects caused by manual picture adjustment are avoided, the adjustment precision is improved, the labor cost is reduced, and the working efficiency is improved.
The method provided by the embodiment of the invention can be applied to any business system with an image processing function. Fig. 2 is a system block diagram of a service system provided in an embodiment of the present invention, and the structure shown in fig. 2 is only one example of a service system to which the technical solution of the present invention can be applied. As shown in fig. 2, the business system includes an image processing apparatus. The device includes: the parameter determination module, the reference value determination module, and the scaling processing module may be configured to perform the processing flows shown in fig. 3, 4, and 5, which are described below.

s301, determining the zooming parameters to be adjusted of the picture according to the attributes of the picture.
In the embodiment of the invention, different zooming parameters to be adjusted can be determined according to different application scenes and the attributes of the pictures. For example, in an application scenario in which the size of a photo is adjusted according to the portrait area in a portrait photo, the portrait area is a zoom parameter to be adjusted of the photo. In the application scenario, a region outside the background region in the picture may be acquired as the zoom parameter to be adjusted. For another example, in an application scenario in which the size of the picture is adjusted according to the visual area, the area (i.e., the visual area) of the area outside the white area and the fully transparent area in the picture may be obtained according to the pixel value and the transparency value of each pixel point in the picture, and the area may be used as the scaling parameter to be adjusted.
S302, a reference value for scaling the picture is determined.
In the embodiment of the present invention, the reference value may be preset, or the scaling parameter to be adjusted of one picture may be selected as the reference value from a plurality of pictures to be processed.

And S303, zooming the picture according to the reference value to enable the zooming parameter to be adjusted of the picture to accord with the reference value.
After the reference value used for scaling the pictures is determined, the pictures to be processed are adjusted one by one or in batch according to the reference value, so that the scaling parameters to be adjusted of the pictures conform to the reference value, for example, the scaling parameters to be adjusted of each picture can be all equal to the reference value, or when the picture area of a certain picture is large and the scaling parameters to be adjusted are small, the scaling parameters to be adjusted of the picture can be smaller than the reference value.
According to the image zooming processing method provided by the embodiment of the invention, the zooming parameter (specific area) to be adjusted of the image is accurately determined according to the attribute of the image, and the image can be automatically zoomed and adjusted according to the specific requirement (reference value), so that the defects caused by manual image adjustment are avoided, the adjusting precision is improved, the labor cost is reduced, and the working efficiency is improved.

S402, selecting the scaling parameter to be adjusted of one picture as a reference value from a plurality of pictures to be processed.
Specifically, the smallest scaling parameter to be adjusted may be selected as the reference value from the plurality of pictures to be processed. Of course, in order to avoid that all the pictures look small due to the minimum to-be-adjusted scaling parameter being too small, the scaling parameter to be adjusted with the middle size may be selected from the multiple to-be-processed pictures, or the minimum to-be-adjusted scaling parameter not lower than the preset area threshold may be selected as the reference value.
And S403, calculating the target length and width of the picture to be processed.
Specifically, the target length and width of the picture can be calculated according to the following formulas (1) and (2):
A/B＝a/b………………………………………………………………...(1)
a*b*p＝S………………………………………………………………..(2)
the method comprises the steps of obtaining a scaling parameter of a picture, wherein A and B are the original length and width of the picture respectively, a and B are the target length and width of the picture respectively, p is the proportion of the scaling parameter to be adjusted of the picture in the original area of the picture, and S is a reference value. Specifically, the ratio p of the to-be-adjusted scaling parameter of the picture to the original area of the picture can be obtained by calculation according to the number of pixel points covered by the to-be-adjusted scaling parameter and the total number of pixel points of the whole picture.
