Aiming at the problem that the prior art can not realize the selection of any region of the layer, the invention provides a new solution. The invention introduces the concept of a template, and the pictures on the layer are output and displayed after being mapped through template selection and output, wherein the template comprises two parts of contents, one part is used for selecting the pictures, and the other part is used for outputting the selected pictures.
The whole idea is as follows: and displaying an original picture on the picture layer, wherein the first template is used for selecting the picture on the picture layer, and selecting the picture of any area of the original picture by modifying the template parameters of the first template. And mapping the picture selected by the first template to a second template, and outputting and displaying at any position by modifying template parameters of the second template.
The following is a detailed description of the above method:
fig. 2 is a flowchart of a method for processing an image according to an embodiment of the present application, as shown in fig. 2, the method includes the steps of:
step S202, determining a layer to be edited, wherein the layer is used for displaying a media picture;
step S204, selecting a target media picture in the image layer by using a first template, wherein the first template is used for selecting the media picture in the image layer;
step S206, mapping the target media picture to a second template;
step S208, displaying the target media picture through the second template in any area in the layer.
Through the steps, the pictures on the picture layer are selected and output through different templates and are mapped to be output and displayed, wherein the templates comprise two parts of contents, one part of the contents is used for selecting the pictures, the other part of the contents is used for outputting the selected pictures, the purposes of selecting the pictures in any area on the picture layer and then outputting the selected pictures are achieved, and therefore the technical effect of improving the flexibility of user operation is achieved.
According to an alternative embodiment of the present application, step S204 is implemented by: determining layer parameters of the layer; determining the positions of the layers and the first template according to the layer parameters of the layers and the template parameters of the first template; and determining the target media picture according to the position of the first template relative to the layer and the intersection area of the first template and the layer.
According to another optional embodiment of the present application, the layer parameters include vertex coordinates of the layer and width-height information of the layer, the template parameters include vertex coordinates of the first template and width-height information of the first template, and determining the position of the first template relative to the layer according to the layer parameters of the layer and the template parameters of the first template includes: determining the vertex coordinates of the first template relative to the layer according to the vertex coordinates of the first template and the vertex coordinates of the layer; determining a target media picture according to the position of the first template relative to the layer and the intersection area of the first template and the layer, comprising: taking the vertex coordinates of the first template relative to the layer as the vertex coordinates of the target media picture; the width and height information of the intersection area is used as the width and height information of the target media picture.
Assuming that the layer parameters of the layer are (x 1, y1, layerWidth, layerHeight), the template parameters of the first template are (x 2, y2, w1, h 1). The vertex coordinates of the first template with respect to the layer are (x 2-x1, y2-y 1), the size of the intersection area between the layer and the first template is (interwtw, interthh), and the parameters of the target media frame selected by the first template may be expressed as (x 2-x1, y2-y1, interwtw, interthh). The size of interwtw and interh may be calculated by calling an existing interface.
Note that x1 and y1 are vertex coordinates of the layer, and layerWidth and layerHeight are width information of the layer in the horizontal direction and height information of the layer in the vertical direction, respectively. X2, y2 are the vertex coordinates of the first template, and w1, h1 are the width information of the first template in the horizontal direction and the height information of the first template in the vertical direction, respectively.
In some optional embodiments of the present application, when step S206 is performed, a width ratio and a height ratio of the second template and the first template are determined, respectively; if the width proportion and the height proportion are 1, mapping the target media picture to the second template according to the vertex coordinates of the target media picture and the width and height information of the target media picture; and if the width proportion or the height proportion is not 1, mapping the target media picture to the second template according to the vertex coordinates of the target media picture and the width proportion and the height proportion.
In further alternative embodiments of the present application, mapping the target media picture to the second template in terms of a width scale and a height scale includes: multiplying the width information of the target media picture by the width proportion to obtain the width information of the target media picture after the target media picture is mapped to the second template; and multiplying the height information of the target media picture by the height proportion to obtain the height information of the target media picture after the target media picture is mapped to the second template.
Fig. 3a is a schematic diagram of adding templates on a layer, and as shown in fig. 3a, adding templates A1 and A2 on a layer a, respectively, generates a first template and a second template according to an embodiment of the present application. The positions, the sizes and the angles of the first templates A1 and the first templates A2 are adjusted according to the requirements, so that the first templates A1 and the first templates A2 can select the pictures of the required parts on the image layer. The added template may be shaped, here rectangular as an example.
Fig. 3b is a schematic diagram of mapping a frame selected by a first template to a second template, and as shown in fig. 3b, the frame content selected by the first template A1 is displayed on the second template A1, and the frame content selected by the first template A2 is displayed on the second template A2 according to an embodiment of the present application.
Assuming that the width and height of the first template are W1 and H1, respectively, and the width and height of the second template are W2 and H2, respectively, the following relationship exists between the first template and the second template:
horizontal wratio=w2/W1
Vertical hratio=h2/H1
Where wratio is the horizontal ratio and hratio is the vertical ratio.
Mapping the picture content selected by the first template to the second template for output, wherein the specific mapping process is as follows:
if the ratio of the width and height information of the second template to the width and height information of the first template is 1:1, the picture selected by the first template can be directly mapped to the second template.
If the ratio of the width and height information of the second template to the width and height information of the first template is not 1:1, the picture selected by the first template is required to be mapped to the second template according to the corresponding ratio value, and the specific mapping method is as follows:
the parameters of the target media picture selected by the first template are (x 2-x1, y2-y1, intersetw, interseth), and the picture mapped to the second template is (x, y, w, h) through horizontal and vertical scaling. Wherein, there is the following relation between the parameters of the picture mapped to the second template and the parameters of the target media picture selected by the first template:
x＝(x2–x1)*wratio；
y＝(y2–y1)*hratio；
w＝wratio*interestW；
h＝hratio*interestH；
wratio is the ratio of the width information of the second template to the width information of the first template, and hratio is the ratio of the width information of the second template to the height information of the first template.
In some optional embodiments of the present application, when performing step S206, it is further required to determine the rotation angle of the layer and the rotation angle of the first template; determining the relative angle between the first template and the layer according to the rotation angle of the layer and the rotation angle of the first template; determining a rotation angle of the second template, and taking the difference between the rotation angle and the relative angle of the second template as a target rotation angle after the target media picture is mapped to the second template; and mapping the target media picture to the second template according to the target rotation angle.
If the layer rotates by an angle A, the first template rotates by an angle B, and the rotation angle of the first template relative to the layer is B-A; and the second template rotates by an angle C, so that the angle of the output picture is C- (B-A).
According to an alternative embodiment of the present application, the first template and the second template are located on the same layer, and the number is one or more.
It will be appreciated that the first template and the second template are present in pairs, the same number. Under the default condition, one layer only has one template (a first template and a second template), and more templates can be added for the layer according to the needs of a user, so that the editing of a complex scene is solved.
According to another alternative embodiment of the present application, before executing step S204, the template parameters, rotation angles, and shapes of the first template and the second template need to be set, respectively, and the shapes include a plurality of preset shapes and user-defined shapes.
The shapes of the first template and the second template may be rectangular, or may be other special shapes (circular, elliptical, five-pointed star, etc.). The template parameters of the templates are adjustable, and the template shape is customized by modifying the template parameters.
By the method, the technical effect of selecting pictures in any size, any angle and any shape in any region of the layer by using the first template can be realized.
In other alternative embodiments of the present application, step S208 is implemented by the following method: setting the position of the second template; and displaying the target media picture in the layer according to the rotation angle and the position of the second template.
The template parameters of the first template and the template parameters of the second template can be modified, the creative scene is realized, and the flexibility of scene editing is improved.

Under the default condition, one layer has only one template, more templates can be added for the layer according to the needs of a user, and the editing of a complex scene is solved. The templates support special-shaped templates and custom shape templates.
