[0016] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0017] Figure 1 FIG. 1 is a flow chart of a trademark graphic code typesetting method provided by an embodiment of the present invention. Figure 1 As shown, the method includes: Step S101, determining the dot code value, code system and shape and size of the image to be generated; Specifically, the embodiment of the present invention uses a dot matrix code system that supports adjustable pixel density per unit area, and micro-dot codes are preferred. Micro-dot codes are sparse dot matrix codes with high robustness. They are a closed encoding algorithm and decoding algorithm. The code image cannot be read by other open source code decoding algorithms. Compared with the traditional dense two-dimensional code that converts code values ​​into binary 1 and 0 and arranges them in the form of deep and shallow code points, the code values ​​of micro-dot codes are converted into binary data and there will be an obvious gap of greater than or equal to 1 data position between the data, and the code value can be a string of any character encoding. The shape of the image to be generated can be any regular image or an irregular image.

[0018] Step S102, determining a mask of the image to be generated according to the shape and size of the image to be generated, wherein the mask of the image to be generated includes at least black, white and gray; Specifically, in order to directly reflect the trademark, LOGO, and logo in the area where the code is sprayed on the product packaging or the body and maintain aesthetics, the displayed trademark, LOGO, and logo need to be integrated with the dot matrix code in one area, to replace the traditional solution of using one area to place the trademark, LOGO, and logo, and coding a rectangular area separately. This is not aesthetically pleasing and wastes extra surface space of the product. In an embodiment of the present invention, a mask must be set before generating an image. The shape and size of the mask are consistent with the shape and size of the image to be generated, and the color distribution of the mask should be set corresponding to the image to be generated. Preferably, the mask includes at least black, white, and gray, the value corresponding to the black pixel is 0, the value corresponding to the white pixel is 255, and the value corresponding to the gray pixel is 1-254, such as Figure 2 shown.

[0019] Step S103, generating an original dot code binary array according to the dot code value, the code system and the shape and size of the image to be generated; Specifically, in the embodiment of the present invention, according to the code value, the dot matrix code is generated by the coding algorithm of the code system itself, and converted into the original dot matrix code binary array, which is composed of "0" and "1". It can be understood that the dot matrix code is divided into a number of pixels of appropriate size, the value corresponding to the pixel with a dot is 1, and the value corresponding to the pixel without a dot is 0. The shape and size of the original dot matrix code binary array should be consistent with the shape and size of the image to be generated. Figure 3 A schematic diagram of an original dot matrix code binary array of an embodiment is shown. For the sake of clarity, Figure 3 Only simple binary array examples are provided.

[0020] Step S104, generating a synthetic array of image-code fusion according to the mask of the image to be generated and the original dot code binary array, wherein the synthetic array of image-code fusion is a binary array; Specifically, when the value corresponding to the pixel in the mask of the image to be generated is 0, the value corresponding to the pixel at the same coordinate of the synthetic array of the generated image code fusion is 1; when the value corresponding to the pixel in the mask of the image to be generated is 255, the value corresponding to the pixel at the same coordinate of the synthetic array of the generated image code fusion is 0; when the value corresponding to the pixel in the mask of the image to be generated is 1-254, the value corresponding to the pixel at the same coordinate of the synthetic array of the generated image code fusion is the value of the original dot code binary array.

[0021] Step S105 , according to different binary values ​​in the synthetic array of the graphic code fusion, different colors are rendered on pixels corresponding to the binary values ​​to obtain a final dot matrix code image as the trademark graphic code.

[0022] Specifically, when the value corresponding to the pixel in the synthetic array of the fusion of the image code is 0, the pixel where 0 is located is not rendered in color, and when the value corresponding to the pixel in the synthetic array of the fusion of the image code is 1, the pixel where 1 is located is rendered in color, so as to obtain the final dot matrix code image as the trademark graphic code, such as Figure 4 As shown. Figure 4 The image is rendered in black, but if the ink used is C, M, Y, K color ink or spot color ink, or even invisible ink, the final printed pattern can be a color one.

[0023] Figure 5 FIG. 1 is a structural block diagram of a trademark graphic code typesetting system provided by an embodiment of the present invention. Figure 5 As shown, the system includes: a code value size determination unit 1, a mask determination unit 2, an array generation unit 3, a fusion unit 4 and a rendering unit 5, wherein the code value size determination unit 1 is used to determine the code value, code system and shape and size of the image to be generated; the mask determination unit 2 is used to determine the mask of the image to be generated according to the shape and size of the image to be generated, and the mask of the image to be generated includes at least black, white and gray; the array generation unit 3 is used to generate the original dot code binary array according to the code value, code system and shape and size of the image to be generated; the fusion unit 4 is used to generate a composite array of image code fusion according to the mask of the image to be generated and the original dot code binary array, and the composite array of image code fusion is a binary array; the rendering unit 5 is used to perform different color rendering on pixels corresponding to binary values ​​according to different binary values ​​in the composite array of image code fusion to obtain the final trademark graphic code.

[0024] Preferably, the value corresponding to the black pixel in the mask of the image to be generated is 0, the value corresponding to the white pixel is 255, and the value corresponding to the gray pixel is 1-254.

[0025] Preferably, the fusion unit 4 is also used for: when the value corresponding to the pixel in the mask of the image to be generated is 0, the value corresponding to the pixel at the same coordinate of the synthetic array of the generated image code fusion is 1; when the value corresponding to the pixel in the mask of the image to be generated is 255, the value corresponding to the pixel at the same coordinate of the synthetic array of the generated image code fusion is 0; when the value corresponding to the pixel in the mask of the image to be generated is 1-254, the value corresponding to the pixel at the same coordinate of the synthetic array of the generated image code fusion is the value of the original dot code binary array.

[0026] Preferably, the rendering unit 5 is used for: when the value corresponding to the pixel in the synthetic array of the fusion of the graphic code is 0, the pixel where 0 is located is not rendered in color; when the value corresponding to the pixel in the synthetic array of the fusion of the graphic code is 1, the pixel where 1 is located is rendered in color, so as to obtain the final trademark graphic code.
