The first embodiment is as follows:
referring to fig. 1, an embodiment provides a method for generating a watermark according to color, including the following steps:
s1: receiving a first input instruction of a user, and acquiring a to-be-processed processing interface;
specifically, the processing interface is not limited in this embodiment. In specific implementation, the processing interface to be processed includes a display screen or a document of a display. The method can generate the watermark on the display screen of the terminal and can also generate the watermark on the file. Thus, the copyright protection of the data multimedia displayed by the computer can be enhanced, and the copyright protection of the traditional file can be enhanced.
S2: calculating the color matching value of each pixel point on a processing interface to be processed;
specifically, the color matching values are not limited in this embodiment. In specific implementation, the color matching value includes an RGB value or a gray value. The color matching values are mainly used for representing the colors of the pixel points. The color matching values may also be defined using other values capable of representing colors.
S3: receiving a second input instruction of the user to acquire watermark information;
in particular embodiments, the watermark information includes, but is not limited to, images, text, vector images, numbers, letters, and the like. The watermark information includes, but is not limited to, an IP address, a device name, user information, and the like.
S4: receiving a third input instruction of a user, and acquiring a watermark adding position in a processing interface;
in specific implementation, the watermark may be set in the whole display screen or the whole document, or may be set in a partial region of the display screen or the whole document. The user can select to add the watermark at the position needing to be added in the display screen or the whole document according to the self requirement. The user can determine the watermarking position by manually dragging the watermark. The location of the watermarking may also be manually entered by dividing the display screen or the entire document into a plurality of regions. The location of the watermark may also be set by referencing a standard watermark setting template of the system, e.g. tiled, centered, left, etc.
S5: respectively calculating the watermark color matching values of the watermark adding positions according to the color matching values;
s6: and generating the watermark at the watermark adding position in the processing interface according to the watermark information and the watermark matching value.
The method can adjust the color of the watermark according to the color on the processing interface to be processed, so that the color of the watermark is matched with the color of the processing interface as much as possible, the color difference between the color of the watermark and the color of the processing interface is reduced, and the influence on the reading of a user is reduced.
Example two:
referring to fig. 2, the method provided in the second embodiment provides a method for calculating a watermark matching color value based on other embodiments, and specifically includes:
s11: acquiring a color matching value of a pixel point at a watermark adding position on a processing interface, and defining the color matching value as a background initial value;
specifically, the background initial value is a color matching value of a pixel point to be watermarked, and can be understood as a background color.
S12: acquiring a color matching value of the pixel point in the watermark information, and defining the color matching value as a watermark initial value;
specifically, the initial watermark value is a color matching value of the watermark corresponding to the pixel point.
S13: calculating the difference value between the background initial value and the watermark initial value; if the difference value is larger than or equal to the preset maximum color difference value, the watermark color matching value of the pixel point is equal to the average value of the background initial value and the watermark initial value; and if the difference value is smaller than the preset maximum color difference value, the watermark color matching value of the pixel point is equal to the sum of the background initial value and the maximum color difference value.
Specifically, the maximum color difference value may be set to 128. If the difference value between the background initial value and the watermark initial value is larger than or equal to the maximum color difference value, the difference between the watermark and the background color of the display screen or the document is too large, and the generated color of the watermark is the average value of the background initial value and the watermark initial value, namely the color formed by fusing the background color and the watermark color. If the difference value between the background initial value and the watermark initial value is smaller, the two colors are close to each other, and the color of the generated watermark is the sum of the background initial value and the maximum color difference value. The calculation method of the watermark color matching value of the embodiment combines the background initial value and the watermark initial value to calculate, so that the final watermark can keep close to the background color on the basis of keeping the original color system as much as possible.
Example three:
referring to fig. 3, the method provided by the third embodiment provides another method for calculating a watermark matching color value based on other embodiments, and specifically includes:
s21: establishing a color matching value database; the watermark color matching value corresponding to each color matching value is stored in the color matching value database;
s22: acquiring a color matching value of a pixel point at a watermark adding position on a processing interface;
s23: and reading the watermark matching value corresponding to each matching value by using the matching value database.
Specifically, the color matching value database defines the generated watermark colors for each background color. Therefore, when the watermark color matching values are calculated, the corresponding watermark color matching values are respectively read from the color matching value database only by reading the color matching values of the pixel points at the positions where all watermarks are added. The watermark obtained by the method takes the background color into consideration, so that the generated watermark is close to the background color, and the reading of a user is not influenced.
Example four:
referring to fig. 4, the method provided by the fourth embodiment provides another method for calculating a watermark matching color value based on other embodiments, and specifically includes:
s31: reading color matching values of pixel points adjacent to the pixel point at the position where the watermark is added on the processing interface;
s32: and calculating the watermark color matching value of the watermark adding position by utilizing a preset color matching model and the color matching values of adjacent pixel points.
Specifically, when the method calculates the watermark color matching value, the color matching value of the adjacent pixel points is fully considered, so that the obtained watermark color matching value can be comprehensively close to the color of the adjacent pixel points.
Example five:
referring to fig. 5, the method provided by the fifth embodiment provides a watermark generation method based on other embodiments, and specifically includes:
s41: generating the watermark according to the watermark information and the watermark color matching value;
s42: and overlaying the watermark to the position of the watermark adding position in the processing interface.
Specifically, the watermark color matching values of all pixels in the watermark are calculated, and then the corresponding watermark is generated according to the watermark information. For example, the watermark information is company a, and the generated watermark is company a, and the color is close to the background color, which does not affect the reading of the user.
