[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.

[0053] The present invention discloses a method and device for processing a gradient semi-transparent image, which is applied to the processing process of the gradient semi-transparent image. In the prior art, in the output of game art image resources, the image resources are usually output in png and jpg formats. Usually, a part of the output resources are image resources with gradient semi-transparency, which are often huge in number and occupy a relatively large capacity, thereby affecting the size of the game package and the size of the game running memory. In the output of gradient semi-transparent image resources in the past, if the image resources want to compress the capacity, the method of directly shrinking and then enlarging is generally adopted, or the details of the image are sacrificed, which will reduce the image quality in short, which is called "destructive compression". The purpose of the present invention is to perform lossless compression on the gradient semi-transparent image resources, with the quality unchanged and the capacity reduced by more than 90%, so as to give more resources to other needs and further improve the running efficiency and utilization rate of the game. The present invention adopts a new method in the compression and restoration process of the image resources for the gradient semi-transparent image resources to achieve the purpose of reducing the resource capacity and maintaining the quality unchanged.

[0054] In the embodiment of the present invention, the above processing process includes a compression process at the sending end and a restoration process at the receiving end. The sending end and the receiving end can be any terminals. The sending end includes an application for realizing image compression. Preferably, the application is Photoshop. The launching end includes an application for realizing image restoration. Preferably, the application is Unity. Therefore, the present invention provides a method for processing a gradient semi-transparent image, which is applied to the sending end. The execution flow of the method is as follows: Figure 1 As shown, the steps include:

[0055] S101, receiving a gradient semi-transparent image to be processed, and splitting the gradient semi-transparent image to be processed into a gradient part and a color information part;

[0056] In an embodiment of the present invention, the transmitting end receives the semi-transparent image to be processed, opens the gradient semi-transparent image to be processed in the photoshop software of the transmitting end, and each gradient semi-transparent image to be processed in the photoshop software has its own channel, in which black represents 100% transparency and white represents 100% opacity, and obtains the gradient part and color information part of the gradient semi-transparent image to be processed in the channel. The specific acquisition process is as follows: obtain the first channel of the gradient semi-transparent image, and obtain the semi-transparent information of the gradient part in the first channel; obtain the second channel of the gradient semi-transparent image, and obtain the color information of the color information part in the second channel. Among them, the first channel and the second channel are the corresponding channels in the photoshop software, the gradient part is used to characterize the grayscale characteristics of the gradient semi-transparent image to be processed, the gradient part is a grayscale image, the gradient part adopts the black and white channel method, and the semi-transparent information is represented by the black and white channel, and the color information part is used to characterize the color information of the gradient semi-transparent image to be processed, and the color information part is a color image.

[0057] S102, compressing the gradient portion into basic semi-transparent information and a first pixel width, wherein the basic semi-transparent information is a basic unit in which no repeated image features exist in the gradient portion;

[0058] In the embodiment of the present invention, the gradient portion includes semi-transparent information, a black and white channel corresponding to the gradient portion is produced, the semi-transparent information is represented based on the black and white channel, and basic semi-transparent information is selected by cutting in the black and white channel based on the image feature to which it belongs, wherein the basic semi-transparent information is a basic unit for representing the image information in the gradient portion, is the smallest unit to which the same content in the gradient portion can be compressed, and is a non-repeating section in the image feature. Preferably, the basic semi-transparent image is a JPG image, for example, one pixel, such as Figure 2 As shown, the basic translucent information is Figure 2 2-1. At the same time, a first pixel width corresponding to the basic semi-transparent information is obtained, wherein the first pixel width is the pixel width of the basic semi-transparent information in the gradient part. For example, if the gradient part is a gradient picture from top to bottom, the pixel width is the pixel width of the gradient picture.

[0059] Furthermore, the process of making a black and white channel corresponding to the gradient part is as follows: open the image and click the layer panel, directly press ctrl + left mouse button and click the layer to form a selection, open the channel panel, create a new channel and fill the selection with white, and copy and paste the black and white channel image into the layer panel.

[0060] S103, compressing the color information part into basic color information and a second pixel width, wherein the basic color information is a basic unit without repeated color features in the color information;

[0061] In an embodiment of the present invention, the color information part includes the color features of the gradient semi-transparent image to be processed, the color features are traversed, and basic color information is selected from the color features by cutting, wherein the basic color information is a basic unit in which there is no repeated color feature in the color information, wherein preferably, the color feature is a color value corresponding to a color, and the basic color information is the smallest unit containing all the color information in the gradient semi-transparent image to be processed, which is a non-repeated section in the color feature, and preferably, the basic color information unit is an IPG image such as Figure 2 As shown, the basic color information is shown in 2-2.

[0062] Furthermore, if the color part information is a single color without gradient, the basic color information can be directly absorbed by using an eyedropper tool.

[0063] S104: Send the basic semi-transparent information, the first pixel width, the basic color information, and the second pixel width to a receiving end.

[0064] In the embodiment of the present invention, for the gradient part, not all information is retained during the compression process, only the basic semi-transparent information and the first pixel width are retained, so the occupied space is small. Figure 2 The basic semi-transparent information after the gradient part is compressed is identified based on the image viewing software, and the information obtained is as follows: Project type: IPG image file of image viewing software, resolution: 1×455, size: 1.55KB. In the process of compression, the color information is not fully retained, only the basic color information and the second pixel width are retained, so the space occupied is small. Figure 2As shown, after the color information is partially compressed, the basic color information is identified based on the image viewing software, and the obtained information is as follows: Project type: Image Viewer JPG picture file, resolution: 3×3, size: 1.10KB. After compression based on the above compression method, the gradient semi-transparent picture to be processed is 2.65KB, which reduces the space occupied. Further, the basic semi-transparent information, the first pixel width, the basic color information and the second pixel width are sent to the receiving end, so that the receiving end can restore the gradient semi-transparent picture to be processed based on the basic semi-transparent information, the first pixel width, the basic color information and the second pixel width.

[0065] The present invention discloses a method for processing a gradient semi-transparent image, which is applied to a sending end. The method comprises: receiving a gradient semi-transparent image to be processed, splitting the gradient semi-transparent image to be processed into a gradient part and a color information part; compressing the gradient part into basic semi-transparent information and a first pixel width, wherein the base semi-transparent information is a basic unit in which no repeated image features exist in the gradient part; compressing the color information part into basic color information and a second pixel width, wherein the basic color information is a basic unit in which no repeated color features exist in the color information; and sending the basic semi-transparent information, the first pixel width, the basic color information, and the second pixel width to a receiving end. In the above process, when the gradient part and the color information part are compressed, only the basic semi-transparent information and the first pixel width, the basic color information and the second pixel width are retained, which reduces the storage of information during the compression process, and retains the basic color information and the basic semi-transparent information, thereby ensuring the quality of the image.

[0066] The embodiment of the present invention provides a method for processing a gradient semi-transparent image, which is applied to a receiving end. The execution flow of the processing method is as follows: Figure 3 As shown, the steps include:

[0067] S201, receiving basic translucent information, a first pixel width, basic color information, and a second pixel width;

[0068] In the embodiment of the present invention, preferably, the receiving end includes a game engine Unity, and the receiving end receives the sent basic translucent information, the first pixel width, the basic color information and the second pixel width.

[0069] S202, generating a gradient part based on the basic semi-transparent information and the first pixel width;

[0070] In an embodiment of the present invention, restoration is performed based on the basic semi-transparent information and the first pixel width information. The restoration process is as follows: the basic semi-transparent information is stretched to the original size along the non-gradient direction based on the first pixel width to obtain the gradient part.

[0071] S203, generating a color information part based on the basic color information and the second pixel width;

[0072] In an embodiment of the present invention, restoration is performed based on the basic color information and the second pixel width, and the restoration process is as follows: the color information based on the second pixel width is stretched to the original size along a non-gradient direction to obtain the color information part.

[0073] Furthermore, if the basic color information is a single color without gradient, the second pixel width includes two pixel width values:

[0074] S204: superimpose the gradient part and the color information part to obtain a gradient semi-transparent image to be processed.

[0075] In the embodiment of the present invention, the gradient part and the color information part are based on the game engine Unity, and the two are superimposed to obtain the gradient semi-transparent image to be processed. The way of superimposing the two kinds of image information in the game engine is similar to Photoshop, but the process is reversed. The color block showing the color information part needs to be enlarged to the original size, and the channel resource showing the gradient part also needs to be enlarged to the original size. The superposition of the two will automatically generate the gradient semi-transparent image to be processed.

[0076] The present invention discloses a method for processing a gradient semi-transparent image, which is applied to a receiving end. The method comprises: receiving basic semi-transparent information, a first pixel width, basic color information, and a second pixel width; generating a gradient part based on the basic semi-transparent information and the first pixel width; generating a color information part based on the basic color information and the second pixel width; and superimposing the gradient part and the color information part to obtain a gradient semi-transparent image to be processed. In the above process, the gradient part can be restored to an image with unchanged quality based on the basic semi-transparent information and the first pixel width, and the color information part can be restored to an image with unchanged quality based on the basic color information and the second pixel width. Since the image quality of the gradient part and the color basic information part remains unchanged, the quality of the gradient semi-transparent image to be processed superimposed on the gradient part and the color information part remains unchanged.
