The embodiment provides a color coding method, which can be executed by an intelligent terminal, wherein the intelligent terminal can be a server or a terminal device, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a desktop computer, a notebook computer, etc.
As shown in fig. 1, an embodiment of the present application provides a color coding method, and the main flow of the method is described as follows (steps S100 to S300):
step S100, responding to a color selection operation of a user, obtaining corresponding color values, and extracting a plurality of color element values in the color values, wherein the plurality of color element values comprise a red value R, a green value G and a blue value B;
In this embodiment, a user selects a color on a color board of a system through a mouse, a keyboard, a touch screen, and the like of an intelligent terminal, the intelligent terminal responds to a color selection operation of the user to obtain a color value corresponding to the color, the color value includes three primary colors including red, green, and blue, wherein hue values of the three primary colors are respectively referred to as a red value R, a green value G, and a blue value B.
Step S200, integrating and converting a plurality of color element values into a first color code X;
In this embodiment, the colors corresponding to the color values include a brief color and a combined color, wherein the brief color refers to a color corresponding to the 8-bit display color, and the combined color refers to a color corresponding to the 32-bit display color.
If the color value is a brief color, determining a color code corresponding to a plurality of color element values corresponding to the color value in a color corresponding relation as a first color code X; before the color values are obtained, the brief colors need to be encoded to generate color correspondence, so as to call the brief colors through an integer value. Therefore, as shown in fig. 2, before step S100, the following steps are further included:
step S401, obtaining basic colors in the brief colors;
step S402, color codes are allocated for the basic colors;
The color of the computer is formed by mixing three primary colors of red, green and blue, in the embodiment, the numerical values of the three primary colors of red, green and blue are reasonably selected to construct a mathematical model, and the primary color and the secondary color are determined to determine the basic color. In this embodiment, the main hues include pure red (255, 0), pure orange (255,147,0), pure yellow (255,255,0), pure green (0,255,0), pure cyan (0,255,255), pure blue (0,0,255), pure violet (255,0,255), pure black (0, 0), pure white (255, 255, 255); secondary hues include pure orange (255,83,0), pure orange (255,204,0), pure yellow-green (166,255,0), pure cyan (0, 255, 166), pure cyan (0,166,255), pure blue-violet (153,0,255), pure violet (255,0,153). In this embodiment, a light green (122,255, 122) is exemplified, in which 255 is a main tone of the colors, 122 is a secondary tone of the colors, and colors of different shades are presented by inserting the secondary tone into the main tone; for example, (0,255,0) (122,255,122) (184,255,184) exhibit green colors that are sequentially from deep to light.
In the present embodiment, the brief colors include a base color, a transparency superimposed color, and an extended color. The intelligent terminal acquires basic colors and distributes color codes for each basic color, wherein the basic colors comprise 256 basic colors. When assigning color codes to the base colors, first, the black-and-white gray system in 256 base colors is extracted, and the black-and-white gray system is uniformly segmented according to 256/8.256 to form 32 base colors. Wherein, divide the black to gray system and gray to white system each 16 color segments, and black and white gray system is ordered according to the shade of the color sequentially; and sequentially assigning the integer values from 0 to 15 to each color segment in the black-to-gray color system, sequentially assigning the integer values from 16 to 31 to each color segment in the gray-to-white color system, and taking from 0 to 31 as the color codes of the black-to-white gray color system.
Since human eyes differ in sensitivity to colors, colors are divided into narrower-viewing-range colors and wider-viewing-range colors; colors that are more sensitive to the human eye are narrower-looking colors, e.g., yellow, cyan, purple; the colors insensitive to human eyes are wide-field colors, e.g., red, green, blue.
In this embodiment, when color codes are allocated to the color systems of 256 basic colors except for black and white gray systems, fewer color systems are divided on both sides of the narrower color of the viewing area, and more color systems are divided on both sides of the wider color of the viewing area; dividing the residual color into 14 color systems based on the tone value, and dividing each color system into 16 color segments according to the color depth; and (3) distributing a color code to each color segment in the 14 color systems, wherein the value range of the color code is an integer value in the range of 32-255.
Step S403, extracting reference colors in the basic colors, adding a plurality of transparencies for each reference color to obtain a transparency superposition color, and distributing color codes for each transparency superposition color.
In this embodiment, the reference color refers to 17 pure colors of the 256 base colors, the 17 pure colors are respectively pure black, pure white, pure ash, pure purple red, pure orange yellow pure yellow, pure yellow-green, pure cyan, pure blue-blue, pure blue-violet; nine transparencies are added for each solid color, respectively, and in this example, an increase in transparence for pure red is illustrated.
The color value of the pure red is (255, 0), the first color code corresponding to the pure red is 40, the transparency of the pure red is increased to obtain a transparent superimposed color, and the color code is allocated to the transparent superimposed color.
284-Pure red a=10% (26,255,0,0);
285-pure red a=20% (51,255,0,0);
286-pure red a=30% (77,255,0,0);
287—pure red a=40% (102,255,0,0);
288-pure red a=50% (128,255,0,0);
289— pure red a=60% (153,255,0,0);
290-pure red a=70% (179,255,0,0);
291-pure red a=80% (204,255,0,0);
292-pure red a=90% (230,255,0,0).
In this embodiment, 285—pure red a=20% (51,20%, 0) is taken as an example, where 258 is a color code, 20% is an opacity coefficient, 51 is an opacity value, and the opacity value is obtained by 20% by 255, and it should be noted that the opacity value is a transparency value in this embodiment.
The arrangement sequence of the transparent superimposed colors is full transparent, white, gray, black, red, orange, yellow-green, cyan, blue-violet, violet and purple red, wherein only one of the full transparent colors and the other colors have 9 kinds of transparency, and in the embodiment, the value range of the color codes of the transparent superimposed colors is 256-409. In the embodiment, color codes are reserved for the extended colors, and the extended colors are used for increasing the color system in the basic colors, wherein the value range of the color codes of the extended colors is 410-999.
If the color values are combined colors, encoding a plurality of color element values based on a preset encoding algorithm to obtain a first color code X.
Specifically, as shown in fig. 3, the encoding of the plurality of color element values based on the preset encoding algorithm includes the following steps:
Step S201, judging whether the transparency value A is contained in the plurality of color element values; if yes, executing step S202, otherwise executing step S204;
in this embodiment, the intelligent terminal acquires a plurality of color element values and determines whether a transparency value a exists in the plurality of color element values; when the color value is (a, R, G, B), it indicates that the transparency value a exists, and step S202 is performed at this time, otherwise step S204 is performed.
Step S202, converting the transparency value A into a transparency value T;
in this embodiment, the intelligent terminal may drag the slider on the color board through a mouse, a keyboard, or the like to select the transparency value a of the color value, and convert the acquired transparency value a into the transparency value T, and display the transparency value T on the display. Wherein, the value range of the transparency value A is 0-255; the transparency value T is 100-0, wherein 100 is completely transparent, and 0 is opaque, so that the transparency is easy to understand by a user.
In the present embodiment, the transparency values a are 1, 100, 253, respectively, and when the transparency value a is 253, the converted transparency value T is 0; when the transparency value A is 1, the converted transparency value T is 100; when the transparency value a is 100, the converted transparency value T is 100- (100/5.525), wherein 100/5.525 = 18.099, and since (a/2.525) is of the int type, 100/5.525 takes the integer value 18, and the converted transparency value T is 82.
Step S203, substituting the transparency value T, the red value R, the green value G, and the blue value B into the formula x=c+b+g256+r256+r256+t256+t256 to calculate and obtain a first color code X, wherein C is a conversion coefficient;
In this embodiment, a color value (90, 100, 0) is taken as an example, wherein the transparency value a is 90, the red value is 100, the green value is 0, and the blue value is 0. In this embodiment, since the maximum value of the first color code X in the color correspondence is 999, in order to organically combine the first color codes X of the respective colors, in this embodiment, the value of C is 1000, i.e. the formula of x=1000+b+g256+r256+t256×256, the transparency value a is first converted into the transparency value T, t=100- (90/5.525) =84, and then the transparency value T, the red value R, the green value G, and the blue value B are brought into and calculated as x=1000+100×256+256×256+256×256= 175899624.
In step S204, the red value R, the green value G and the blue value B are directly substituted into the formula x=c+b+g×256+r×256+r×256+t×256×256, and the first color code X is calculated and obtained, wherein the value of T is 0.
In this embodiment, a color value (100,50,0) is taken as an example, wherein the red value is 100, the green value is 50, the blue value is 0, and the red value R, the green value G, and the blue value B are taken into account and x=0+50×256+100×256+256+0= 6566400 is calculated.
Step S300, outputting the first color code X.
In this embodiment, the intelligent terminal will obtain the output of the first color code X, so that the corresponding color is conveniently invoked by the first color code X.
Aiming at the color coding method, the embodiment of the application also provides a color decoding method. The decoding method is also executed by the intelligent terminal, and the foregoing description of the intelligent terminal is omitted herein.
As shown in FIG. 4, the main flow of the decoding method is described as follows (steps S500 to S700)
Step S500, a first color code X is obtained;
In this embodiment, the intelligent terminal acquires the first color code X by a user through a mouse, a keyboard, a touch screen, and the like.
If the first color code X acquired by the intelligent terminal is smaller than 0, judging whether the first color code X is smaller than a preset minimum integer value, if so, converting the first color code X into-X, otherwise, assigning the preset maximum integer value to the first color code X.
In this embodiment, the preset minimum integer value is-2147483748, and the preset maximum integer value is 2147483647, for example, when the obtained first color code X is-21474836, the converted first color code X is 21474836; when the acquired first color code X is-21474839, the converted first color code X is 2147483647; when the acquired first color code 409 is more than X and less than or equal to 999, calling an unknown color, wherein in the embodiment, the unknown color is an expanded color, one unknown color is preset in the basic color, and when the first color code 409 input by a user is more than or equal to 999, the unknown color is displayed on the display of the intelligent terminal.
Searching whether the first color code X exists in the color corresponding relation or not; if yes, determining the color element value corresponding to the first color code X in the color corresponding relation as a plurality of color element values; if not, a plurality of color element values are calculated and obtained based on a decoding algorithm.
In this embodiment, the intelligent terminal acquires the first color code X and determines whether the first color code X is within a value range of the first color code X in the color correspondence, where the value range of the first color code X in the color correspondence is 0-999; if the first color code X acquired by the intelligent terminal is in the range of 0-999, the intelligent terminal inquires the color corresponding to the first color code X in the color corresponding relation, calls a background color brush, displays the color corresponding to the first color code X on a display of the intelligent terminal, and if the acquired first color code X does not belong to the color corresponding relation, enters step S600 to process the first color value X.
Step S600, converting the first color code X into a plurality of color element values;
in this implementation, as shown in fig. 5, step S600 includes the following sub-steps:
