In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for forming a special effect of a kaleidoscope according to the present invention is shown, and the embodiment of the present invention may specifically include the following steps:
The method for forming the kaleidoscope special effect is applied to special effect processing and synthesizing software of high-quality and high-efficiency videos and images, and can be used for carrying out special effect processing on the videos as well as special effect processing on the images; the number of slices refers to the number of slices in the formed kaleidoscope special effect image.
Specifically, before the image kaleidoscope special effect processing is performed, the width and the length of the image and the number of slices input by the user are acquired.
And 102, determining the slice angle of the slice according to the number of the slices.
Specifically, the slices have the same shape and size, and in the kaleidoscope special effect image to be formed, the slices surround the central point of the image to form the complete kaleidoscope, so that the slice angle can be obtained according to the number of the slices.
And 103, intercepting the image according to the slice angle and the width to obtain a sampling slice.
Specifically, a sampling slice is obtained by cutting from the image according to the slice angle and the width of the image, and the sampling slice is a basic element filled in the slice.
And 104, creating a square image to be filled with the side length of the square image to be filled.
And 105, determining the shape, size and position of each slice in the square image to be filled according to the slice angle.
And the slices in the square image to be filled form a kaleidoscope around the central point of the square image to be filled, and the slices have the same shape and size.
Specifically, a square image to be filled is created by taking the length of the image as the side length, the shape size and the position of each slice in the square image to be filled are determined according to the slice angle, and each slice in the square image to be filled forms a kaleidoscope around the center point of the square image to be filled.
And 106, filling the sampling slices into each slice of the square image to be filled to form a kaleidoscope special effect image.
Specifically, the sampling slices obtained by cutting out the image are used as basic elements to be filled in each slice of the square image to be filled, and a kaleidoscope special effect image is formed.

Specifically, if the number of slices input is x, the number of mirror-image slices is also equal to x, so that the kaleidoscope special effect image to be formed is divided into 2x angles with the image center point position as the origin, resulting in a slice angle a = 360 °/2 x. For example, if the number of slices to be input is 3, then the number of mirror-image slices is also equal to 3, so that the kaleidoscope special effect image to be formed is divided into 6 angles with the image center point as the origin, resulting in a slice angle a = 360 °/6 =60 °.
And step 203, intercepting a square image with the side length being the width from the image.

In an example of the present invention, a square image with a length of one side being a width may also be cut out based on other positions of the image, for example, midpoint positions of four sides of the image (corresponding to midpoint positions of four sides of the square image), or a certain point position may be specified in the image according to a user requirement, which is not limited by the embodiment of the present invention.
