Detailed Description
The present application is described in further detail below with reference to the attached drawings.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The embodiment provides a color coding method, which may be executed by an intelligent terminal, where the intelligent terminal may be a server or a terminal device, where the server may be an independent physical server, a server cluster or a distributed system formed by multiple physical servers, or a cloud server providing cloud computing services. The terminal device may be a smart phone, a tablet computer, a desktop computer, a notebook computer, etc., but is not limited thereto.
As shown in fig. 1, the present embodiment provides a color coding method, and the main flow of the method is described as follows (steps S100 to S300):
step S100, responding to color selection operation of a user, acquiring a corresponding color value, and extracting a plurality of color element values in the color value, 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 panel of the system by using a mouse, a keyboard, a touch screen, and the like of the intelligent terminal, and the intelligent terminal obtains a color value corresponding to the color in response to a color selection operation of the user, where the color value includes three primary colors including red, green, and blue, and hue values of the three primary colors are referred to as a red value R, a green value G, and a blue value B, respectively.
Step S200, integrating and converting a plurality of color element values into a first color code X;
in this embodiment, the color corresponding to the color value includes a simple color and a combined color, where the simple color is a color corresponding to an 8-bit display color, and the combined color is a color corresponding to a 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 the color corresponding relationship as a first color code X; before obtaining a color value, a color correspondence relationship needs to be generated by encoding a simple color, so as to call the simple color by an integer value. Therefore, as shown in fig. 2, before step S100, the following steps are further included:
step S401, acquiring basic colors in the brief colors;
step S402, distributing color codes for basic colors;
the color of the computer is formed by mixing three primary colors of red, green and blue, in the embodiment, numerical values of the three primary colors of red, green and blue are reasonably selected to construct a mathematical model, and the basic color is determined by determining the primary hue and the secondary hue. In this embodiment, the dominant hue includes pure red (255,0, 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, 0), pure white (255,255, 255); the secondary hues include pure orange red (255,83,0), pure orange yellow (255,204,0), pure yellow green (166,255,0), pure cyan green (0,255, 166), pure blue cyan (0,166,255), pure blue violet (153,0,255), pure magenta red (255,0, 153). In the present embodiment, a light green color (122, 255, 122) is taken as an example for explanation, wherein 255 is a main tone in the color, and 122, 122 is a secondary tone in the color, and different shades of the color are presented by inserting the secondary tone into the main tone; for example, the colors green (0,255,0) (122,255,122) (184,255,184) appear sequentially from dark to light.
In the present embodiment, the brief colors include a basic color, a transparency superimposed color, and an extended color. The intelligent terminal obtains basic colors and distributes color codes for each basic color, wherein the basic colors comprise 256 basic colors. In assigning color codes to the basic colors, first, black, white, and gray systems among the 256 basic colors are extracted, and the black, white, and gray systems are uniformly segmented according to 256/8.256 to form 32 reference colors. Wherein, the black-to-gray color system and the gray-to-white color system are respectively divided into 16 color segments, and the black, white and gray color systems are sequentially ordered according to the shade of the color; the integer values of 0 to 15 are assigned to each color segment of the black-to-gray system in turn, the integer values of 16 to 31 are assigned to each color segment of the gray-to-white system in turn, and 0 to 31 are used as the color codes of the black-white-gray system.
Since human eyes differ in sensitivity to colors, colors are divided into a view narrower color and a view wider color; colors that are more sensitive to the human eye are narrower view colors, e.g., yellow, cyan, violet; colors that are insensitive to the human eye are the wide viewing range colors, e.g., red, green, blue.
In the present embodiment, when color codes are assigned to color systems other than the black, white, and gray color systems of the 256 basic colors, the narrower view area color is divided into fewer color systems on both sides, and the wider view area color is divided into more color systems on both sides; dividing the rest colors into 14 color systems based on hue values, namely, purple red, orange yellow, yellow green, cyan, blue violet and purple, and dividing each color system into 16 color segments according to the color depth; and allocating a color code for 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 from the basic colors, adding a plurality of transparencies to each reference color to obtain a transparency superimposed color, and assigning a color code to each transparency superimposed color.
In this embodiment, the reference color refers to 17 pure colors of 256 basic colors, and the 17 pure colors are respectively pure black, pure white, pure gray, pure magenta, pure red, pure orange yellow, pure yellow green, pure cyan, pure blue violet, and pure violet; nine transparencies are respectively added for each pure color, and in this embodiment, the transparency is added for pure red as an example.
The color value of pure red is (255,0, 0), the first color code corresponding to pure red is 40, the transparency is increased for pure red to obtain a transparent superimposed color, and the color code is allocated for 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%,0,0) is taken as an example for explanation, where 258 is a color code, 20% is an opacity coefficient, 51 is an opacity value, and the opacity value is obtained by 20% × 255, and it should be noted that the opacity value in this embodiment is a transparency value a.
The transparent superposed colors are arranged in the sequence of full transparency, white, gray, black, red, orange yellow, yellow green, cyan, blue violet, and purplish red, wherein the full transparency is only one, and the rest colors respectively have 9 transparencies, and in the embodiment, the value range of the color code of the transparent superposed color is 256-409. In this embodiment, a color code is also reserved for expanding the color, and the expanded color is used to increase the color system in the basic color, wherein the value range of the color code of the expanded color is 410-999.
And if the color value is the combined color, encoding the multiple color element values based on a preset encoding algorithm to obtain a first color code X.
Specifically, as shown in fig. 3, encoding a plurality of color element values based on a preset encoding algorithm includes the following steps:
step S201, judging whether a plurality of color element values contain a transparency value A; if yes, executing step S202, otherwise executing step S204;
in this embodiment, the intelligent terminal obtains 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 there is a transparency value a, step S202 is executed, otherwise step S204 is executed.
Step S202, converting the transparency value A into a transparency value T;
in this embodiment, the intelligent terminal can drag the slider on the color plate to select the transparency value a of the color value in a manner of mouse, keyboard, etc., and convert the acquired transparency value a into the transparency value T to display on the display in the form of the transparency value T. Wherein the value range of the transparency value A is 0-255; the value range of the transparency value T is 100-0, 100 represents full transparency, and 0 represents opacity, so that a user can conveniently understand the transparency.
In this embodiment, the transparency values a are 1, 100, and 253, respectively, for example, 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), where 100/5.525=18.099, and since (a/2.525) is int type, 100/5.525 takes the integer value of 18, so 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 a formula X = C + B + G + 256+ R256 + T + 256+ to calculate and obtain a first color code X, where C is a conversion coefficient;
in this embodiment, a color value (90, 100,0, 0) is taken as an example for explanation, where the transparency value a is 90, the red value is 100, the green value is 0, and the blue value is 0. In the present embodiment, since the maximum value of the first color code X in the color correspondence relationship is 999, in order to make the first color codes X of the respective colors organically and completely merge, the value of C in the present embodiment is 1000, that is, the formula is X =1000+ B + G256 + R256 + T256, 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 substituted into X =1000+100 256+84 256+ 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+ T + 256, and the first color code X is calculated and obtained, where the value of T is 0.
In the present embodiment, a color value (100, 50, 0) is taken as an example, where the red value is 100, the green value is 50, and the blue value is 0, and the red value R, the green value G, and the blue value B are substituted to calculate X =0+50 + 256+100 + 256+0= 6566400.
In step S300, the first color code X is output.
In this embodiment, the intelligent terminal obtains the first color code X for output, so as to call the corresponding color through 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, which has already been described above, and is not described herein again.
As shown in FIG. 4, the main flow of the decoding method is described as follows (steps S500 to S700)
Step S500, acquiring a first color code X;
in this embodiment, the intelligent terminal obtains the first color code X 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-2147483648, 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 obtained first color code X is-21474839, the converted first color code X is 2147483647; when the obtained first color code 409 is larger than X and smaller than 999, the unknown color is called, in the embodiment, the unknown color is an expanded color, an unknown color is preset in the basic color, and when the first color code 409 input by the user is larger than X and smaller than 999, the unknown color can be presented on the display of the intelligent terminal.
Searching whether the first color code X exists in the color corresponding relation; if yes, determining color element values corresponding to the first color code X in the color corresponding relation as a plurality of color element values; and if not, calculating and obtaining a plurality of color element values based on a decoding algorithm.
In this embodiment, the intelligent terminal obtains a first color code X, and determines whether the first color code X is within a value range of the first color code X in a color correspondence, where the value range of the first color code X in the color correspondence is 0 to 999; if the first color code X acquired by the intelligent terminal is within the range of 0-999, the intelligent terminal queries the color corresponding to the first color code X in the color corresponding relationship, calls a background color brush, displays the color corresponding to the first color code X on the intelligent terminal display, and if the acquired first color code X does not belong to the color corresponding relationship, then the step S600 is performed 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:
step S601, calculating a second color code Y based on the first color code X, where Y = X-C;
step S602, determining whether the second color code Y is not less than 256 × 256; if yes, the process proceeds to step S603, otherwise, the process proceeds to step S608.
The formula of the color coding section is X = C + B + G × 256+ R × 256+ T × 256, and C takes a value of 1000 in the embodiment of the color coding section, and in order to keep the encoding section and the decoding section in agreement, C also takes a value of 1000 in the present embodiment.
In the present embodiment, the first color code X is 1023345640 for example, and the second color code Y is 1023344640, where 256 × 256=16777216 is calculated based on Y = X-C, and in the present embodiment, the second color code Y is greater than 256 × 256, so the process proceeds to step S603.
Step S603, calculating a transparency value T based on the second color code Y, where T = Y/(256 × 256);
in the present embodiment, taking the data in steps S601 and S602 as an example, the transparency value T is calculated based on T = Y/256 × 256, where the transparency value T is 60 because the second color code Y is 1023344640.
Step S604, calculating a third color code Z based on the second color code Y, wherein Z = Y% (256 × 256), and Z is int type;
in the present embodiment, taking the data in step S603 as an example, the third feature code Z is calculated based on Z = Y% 256 × 256, where% represents the remainder obtained by dividing Y by 256 × 256, and in the present embodiment, the second color code Y is 1023344640, so the third color code Z is 16711680.
Step S605, performing bit AND operation on the binary system corresponding to the third color code Z and the binary system corresponding to 0xFF, taking eight low bits to obtain a blue value B, performing bit AND operation on the binary system corresponding to the third color code Z and the binary system corresponding to 0xFF00, taking eight middle bits to obtain a green value G, performing bit AND operation on the binary system corresponding to the third color code Z and the binary system corresponding to 0xFF0000, and taking eight high bits to obtain a red value R;

Step S606, converting the transparency value T into a transparency value A;
in this embodiment, the transparency value T needs to be converted into the transparency value a, and the specific conversion algorithm is as follows: if the transparency value T is less than or equal to 1, the transparency value A = 255; if the transparency value T is more than or equal to 99, the transparency value A =0; if transparency 1 < T < 99, a transparency value a is calculated based on a =254- (T × 2.54), where T × 2.54 is int-type.
In the present embodiment, the data in step S603 is used as an example, where the transparency value T is 60, and the transparency value a is calculated as 100 based on a =254- (T × 2.54).
Step S607, determining the transparency value a, the red value R, the green value G, and the blue value B as a plurality of color element values;
in the present embodiment, the data in steps S601 to S606 are used as an example, and thus the obtained color value is (100, 255,0,0)
Step S608, performing bit AND operation on the binary system corresponding to the second color code Y and the binary system corresponding to 0xFF, taking eight low bits to obtain a blue value B, performing bit AND operation on the binary system corresponding to the second color code Y and the binary system corresponding to 0xFF00, taking eight middle bits to obtain a green value G, performing bit AND operation on the binary system corresponding to the second color code Y and the binary system corresponding to 0xFF0000, and taking eight high bits to obtain a red value R;
step S609, determining the red value R, the green value G, and the blue value B as a plurality of color element values;
in this embodiment, the step of calculating the red value R, the green value G and the blue value B is the same as step S605, and is not described herein again.
