The method is characterized in that a nine-point picture, namely 9, is a special picture form in the application software development of the android platform, and the file extension name is as follows: 9. png. The preset focal point image is a rectangle, and a certain region of the rectangle is set as a stretchable region, such as the right side and the lower side of the rectangle, or the left side and the upper side of the rectangle, which is not limited in the present invention.
It should be noted that the size of the preset focus image refers to the length and width of the preset focus image, and the size of the picture refers to the length and width of the picture corresponding to the position of the focus to be displayed. And stretching the stretchable region of the preset focal point picture to enable the length and width of the preset focal point picture to be consistent with the length and width of the picture corresponding to the position of the focal point to be displayed. The method comprises the following specific steps: firstly, the length and the width of the picture are acquired, and then the stretchable area of the preset focal point picture is stretched, so that the length and the width of the preset focal point picture are respectively consistent with the length and the width of the picture. For example, the length and width of the picture are 20cm and 10cm, respectively, and then the length and width of the preset focal point picture are also extended to 20cm and 10cm, respectively.
In the second embodiment, stretching the stretchable region of the preset focal point picture realizes that the length and width of the preset focal point picture respectively accord with the length and width of the picture.

and step S22, performing miscut on the canvas to enable the inclination angle of the canvas to be consistent with the inclination angle of the picture corresponding to the position of the focus to be displayed.
In a third embodiment, the miscut is a planar graph obtained by scaling the directional distance from each point of the graph to a line parallel to a certain direction according to a certain proportion in the certain direction. Among them, the miscut usually includes X-direction miscut and Y-direction miscut. By the aid of the staggered cutting, the inclination angle of the canvas is consistent with that of the picture. The method comprises the following specific steps: firstly, determining whether a picture corresponding to the position of a focus to be displayed is inclined in the X direction or the Y direction, then obtaining the inclination angle in the direction, and inclining the canvas in the same direction by the same angle. For example, the picture corresponding to the position of the focus to be displayed is inclined by sixty degrees in the X direction, and then the canvas is also inclined by sixty degrees in the X direction by the cross-cut.
In a third embodiment, the canvas is cut in a staggered manner, so that the inclination angle of the canvas is consistent with that of the picture.
In a fourth embodiment, as shown in fig. 5, based on the first embodiment shown in fig. 2, the step of drawing the preset focal point picture at the position of the focal point to be displayed in the canvas includes:

and step S32, drawing the preset focal point picture at the position of the focal point to be displayed in the canvas.
In a fourth embodiment, the canvas has two attributes, transform valid and transform invalid. When the property of the canvas is effective, the picture in the canvas and the picture with the preset focus are inclined along with the inclination of the canvas. For example, when the inclination angle of the canvas is consistent with the inclination angle of the picture, the attribute of the canvas is switched to be effective in transformation, so that when the position where the focus is to be displayed is drawn to preset the focus picture, the preset focus picture is inclined along with the inclination of the canvas. When the property of the canvas is that the transformation is invalid, the picture in the canvas and the preset focus picture are not inclined along with the inclination of the canvas. For example, when the focus is displayed on the picture corresponding to the position of the focus to be displayed, the attribute of the canvas is switched from effective conversion to ineffective conversion, so that when the canvas is restored to the original state, the picture in the canvas and the preset focus picture are not inclined along with the inclination of the canvas.
It should be noted that the attribute of the canvas may be switched, the condition for triggering attribute switching is preset, and when the preset condition is met, the attribute switching is performed, where the preset condition may be that the adjustment of the inclination angle of the canvas is completed and the preset focal point picture is not yet drawn, or that the preset focal point picture is drawn and the attribute information of the picture corresponding to the position of the focal point to be displayed is not yet acquired, and the present invention is not particularly limited.
In the fourth embodiment, the attribute of the canvas is switched from invalid to valid, and a preset focus picture is drawn at the position of the focus to be displayed in the canvas, so that the preset focus picture is inclined according to the inclination angle of the canvas.
In a fifth embodiment, as shown in fig. 6, on the basis of the fourth embodiment shown in fig. 5, after the drawing the preset focal point picture at the position of the focal point to be displayed in the canvas, the method further includes:
step S33, the attribute of the canvas is switched from effective transformation to ineffective transformation;
and step S34, restoring the original state of the canvas.
In the fifth embodiment, before the cloth is cut by mistake, the original state of the canvas is memorized, and after the picture display focus corresponding to the position of the focus to be displayed is displayed, the original state of the canvas can be quickly recovered. It should be noted that the original state of the canvas is a rectangle, and the canvas is tilted by a certain angle in the X direction or the Y direction by the cross cutting.
In a fifth embodiment, the properties of the canvas are switched from transformation-valid to transformation-invalid and the original state of the canvas is restored. Therefore, when the inclination angle of the picture corresponding to the position of the focus to be displayed is obtained, the canvas is cut in a staggered mode according to the inclination angle of the picture.
In a sixth embodiment, as shown in fig. 7, on the basis of the first embodiment shown in fig. 2, before the obtaining of the attribute information of the picture corresponding to the position of the focus to be displayed, the method further includes:
step S40, acquiring the sizes of all pictures in the current interface;
and step S50, generating the preset focal point image according to the size, wherein the size of the preset focal point image is smaller than the sizes of all the images in the interface.
