Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.
In one or more embodiments of the present specification, the color superimposition method of the present specification may be implemented by a user through a terminal (which may be regarded as an operation device used by the user). The terminal may be used as an execution subject of the color superimposition method, and may include but is not limited to: smart phones, smart watches, tablet computers, and the like. In a possible implementation manner, the color superimposing method provided in this specification may also be implemented on the server side, that is, the server is taken as an execution subject, and these should not be construed as limitations of the present application.
The method of the present specification will be described in detail below with reference to a terminal as an execution subject. Referring to fig. 1, fig. 1 is a main flowchart of a color superimposing method provided in an embodiment of the present specification. As shown in fig. 1, the color superimposition method provided by the present specification includes:
s110: and displaying a color operation interface.
In this step, the terminal has a display screen for displaying a color operation interface. One example is that when the user opens the terminal, the terminal automatically displays the color operation interface; as another example, after the user opens the corresponding APP installed on the terminal, the color operation interface may be displayed on the display screen of the terminal, or the processor of the terminal may cause the display screen to display the color operation interface according to a certain trigger operation of the user on the terminal, and the implementation manner of displaying the color superimposition interface on the terminal does not form a limitation to the present application.
Referring to fig. 2, fig. 2 is a schematic view of a color operation interface of a color superimposition method provided in an embodiment of the present specification. As shown in fig. 2, the color manipulation interface of the present specification includes a first region (in fig. 2, a region of a broken line frame in an upper half portion of the interface) and a second region (in fig. 2, a region of a broken line frame in a lower half portion of the interface). The user can input the color value to be superimposed and a calculation instruction through the first area of the color operation interface, and the second area of the color operation interface can be used for displaying the color obtained after the superimposition. See in particular the subsequent steps.
S120: receiving at least two color values input through the first area and a calculation instruction input through the first area; and displaying colors respectively corresponding to the input color values in the first area.
In this step, the user may input the color value in the first area in the following two ways:
one way is that: a user may input a color selection instruction through the first area of the color operation interface, for example, after the user clicks a position of "color one", "color two", or "color three" in fig. 2, the terminal (e.g., a processor on the terminal) receives the corresponding color selection instruction, and further, the color selection instruction causes the display to display the color selection board on the display. The color-taking plate is preset, and the specification does not explain the color-taking plate in detail. After the color selecting plate is displayed on the color operation interface, a user can select a required color on the color selecting plate, and after a certain color is selected, the terminal receives the selected color value in the color selecting plate.
The other mode is as follows: the user may manually input the corresponding color value through the first region of the color manipulation interface, for example, input a hexadecimal value representing the corresponding color in the manual input region of the first region (the positions respectively located to the right of "color one", "color two", and "color three" in fig. 2), such as "FF 0000 DD", "00 FF 0044" in fig. 2. After the color value is manually input by the user, the terminal acquires the color value manually input by the user, further verifies whether the color value is in a preset format, receives the color value if the verification result is in the preset format, and sends out error prompt information if the verification result is not in the preset format. The preset format may be various, such as: with # hexadecimal color, decimal RGBA color, HSB, HSV, HSL, etc.
It should be noted that, in this step, at least two color values input through the first area are generally received, and the first area of the color operation interface in this example displays an input area with three color values, that is, a person skilled in the art may input three color values in the first area, and may also input two color values in the first area. In addition, a person skilled in the art may also set more than three color value input areas in the first area of the color operation interface according to actual needs, which do not form a limitation to the present application.
It should be further noted that, when the user inputs the selected color through the color-taking plate, the format of the color-taking plate is also the preset format because the color-taking plate is preset, and at this time, the format verification of the color value is not required; when a user manually inputs a color value, because the manual input has a subjective input condition, format verification needs to be performed on the input color value, and once the input format is wrong, an error prompt is sent out to prompt the user to re-input a correct format.
It should be further noted that the color values received by the terminal further include transparency values. For example, when a color value selected from the color-taking plate is received by the terminal, the color value contains a transparency value; when a user manually inputs a color value, the color value may have a transparency value (e.g. the transparency value "DD" in FF0000 DD) or may only input a color value of a transparency value (in this case, the color value only contains red, green and blue values, i.e. such as "FF", "00" and "00" in FF0000 DD), and then input a corresponding transparency value in the transparency value input frame of the first area. The input frame at the rightmost side of the first area in fig. 2 may input a corresponding transparency value, or may adjust the transparency value by sliding a cursor in the input frame of the transparency value, which is not limited in this specification.
Further, in this step, after the terminal receives the color values input through the color operation interface, colors corresponding to the input color values are displayed in the first area. For example, whether the user manually inputs color values or selects color values through the palette, the first region (within the leftmost color box of the first region in fig. 2) displays colors corresponding to the respective color values. Therefore, a user can visually see the specific color corresponding to the color value to be superposed.
In this step, after the at least two color values to be superimposed are input through the color operation interface, the user may input a calculation instruction through the first area, for example, input a corresponding calculation instruction through the "calculation" icon in fig. 2, and the terminal receives the corresponding calculation instruction.
S130: performing superposition calculation on the at least two color values according to the calculation instruction to obtain superposed color values; and displaying the color corresponding to the superposition color value in the second area.
In this step, performing superposition calculation on the at least two color values according to the calculation instruction includes: according to a preset algorithm, the first two color values are subjected to superposition calculation, the calculation result is used as a new color value to be subjected to superposition calculation with the next color value, and the like until the new color value obtained after all the color values are subjected to superposition calculation is used as a superposition color value.
Specifically, if the number of the color values received by the terminal is two, performing superposition calculation on the two color values according to a preset algorithm to obtain a first calculation result, and taking the first calculation result as a superposition color value; if the number of the colors received by the terminal is three, firstly performing superposition calculation on the first color value and the second color value according to a preset algorithm to obtain a first calculation result, then performing superposition calculation on the first calculation result and the third color value according to the preset algorithm to obtain a second calculation result, and taking the second calculation result as a superposition color value; and if the number of the observed and received colors is four, performing superposition calculation on the second calculation result and the fourth color value according to a preset algorithm to obtain a third calculation result, and taking the third calculation result as a superposition color value. And analogizing in sequence, regardless of the number of input color values, performing superposition calculation on the first two color values, and performing superposition calculation on the result of the superposition calculation with the last color value until the final superposition color value is obtained after the superposition calculation of the last color value.
The preset algorithm in this specification will be described in detail below by taking the superposition of the first color and the second color in fig. 2 as an example.
Firstly, the red, green, blue and transparency values in the two color values are respectively converted into numerical values between 0 and 1 according to a preset rule. For example, the hexadecimal system corresponding to the color one is FF0000DD, where the red value is FF, the green value is 00, the blue value is 00, and the transparency value is DD; the hexadecimal system corresponding to the color two is 00FF0044, wherein the red value is 00, the green value is FF, the blue value is 00, and the transparency value is 44; in the calculation, the values of red, green, blue and transparency are in the range of 0 to 1, which can be obtained by dividing the 10-ary color value by 255, so that the value in the range of 0 to 1 corresponding to each of the values of red, green, blue and transparency can be obtained.
And then, respectively calculating the red, green, blue and transparency values in the superposed color values obtained by superposing the first color and the second color according to the following formula:
C1＝(c1*a1*(1.0-a2)+c2*a2)/(a1+a2-a1*a2)；
D1＝(d1*a1*(1.0-a2)+d2*a2)/(a1+a2-a1*a2)；
E1＝(e1*a1*(1.0-a2)+e2*a2)/(a1+a2-a1*a2)；
A1＝a1+a2-a1*a2；
wherein, a1、a2Respectively the transparency values of the two color values; c. C1、c2Respectively is a red value in the two color values; d1、d2Respectively green values in the two color values; e.g. of the type1、e2Respectively a blue value in the two color values; c1The red value in the new color value; d1Green values in the new color values; e1The blue value in the new color value; a. the1Is the transparency value in the new color value.
The superimposed color value obtained according to the above algorithm is "# B34B00E 6" (the color value obtained by superimposing a plurality of colors may also be of another type, that is, the color value obtained by the present scheme supports a plurality of types of color values), which is shown in fig. 2, and further, the color corresponding to the superimposed color value is displayed in the second area of the color operation interface. The calculation result is provided with "#", and a person skilled in the art may or may not carry "#" when manually inputting a color value, which is not limited in the present specification.
In the algorithm, when superposition calculation is performed, a color value is divided into four parts, a red value, a green value, a blue value and a transparency value are calculated respectively, then a calculation result is used as a new color value, and the red value, the green value, the blue value and the transparency value in each color value are converted into numerical values between 0 and 1, namely, four numerical values are used for representing one color, so that superposition calculation of colors with different formats is supported. It should be noted that no matter what format the received color value is, as long as it meets the requirement of the preset format, when the received color value contains a plurality of different formats, the method will convert the values of the different formats into a decimal between 0 and 1.
In addition, it should be noted that, if the color value manually input by the user has a transparency value, and a corresponding transparency value is also input in the transparency value input frame of the first area, at this time, when performing the superposition calculation on the two colors, the transparency value input in the transparency value input frame is preferentially used. That is, if the transparency value is not input in the transparency value input frame, the transparency value in the color value is calculated; and if the corresponding transparency value is input into the transparency value input frame, calculating by using the transparency value input into the input frame.
By the method, the user can input the color value to be superposed and calculated through the color operation interface, and the color corresponding to the superposed color value can be visually seen, so that the user experience is greatly improved. In addition, the method provided in the present specification does not limit the number of superimposed colors, and can perform superimposition calculation for any plurality of colors. Moreover, any color value conforming to the preset format is converted into a numerical range between 0 and 1 for calculation during calculation, and the preset format can contain color values in various different formats, so that the method supports superposition calculation of colors in different formats.
Based on the same thought, this specification also provides a color superimposing apparatus. Referring to fig. 3, fig. 3 is a block diagram of a color superimposing apparatus according to an embodiment of the present disclosure. As shown in fig. 3, the apparatus includes:
the display module 301, the display module 301 is configured to display a color operation interface; the color operation interface comprises a first area and a second area;

Further, each of the color values also includes a transparency value manually entered through the first region.
Optionally, the processing module 303 is specifically configured to: according to a preset algorithm, the first two color values are subjected to superposition calculation, the calculation result is used as a new color value to be subjected to superposition calculation with the next color value, and by analogy, the new color value obtained after all the color values are subjected to superposition calculation is used as a superposition color value.
Further, the preset algorithm is as follows: respectively converting the red, green, blue and transparency values in the two color values into numerical values between 0 and 1 according to a preset rule; calculating new color values obtained after the two color values are superposed according to the following formula:
C1＝(c1*a1*(1.0-a2)+c2*a2)/(a1+a2-a1*a2)；
D1＝(d1*a1*(1.0-a2)+d2*a2)/(a1+a2-a1*a2)；
E1＝(e1*a1*(1.0-a2)+e2*a2)/(a1+a2-a1*a2)；
A1＝a1+a2-a1*a2；
wherein, a1、a2Respectively the transparency values of the two color values; c.

Based on the same concept, the present specification also provides an electronic device, including: at least one processor and a memory, the memory storing a program and configured to execute the above-described color superimposition method by the at least one processor.
Based on the same concept, the present specification also provides a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, implement the color superimposition method described above.
While certain embodiments of the present disclosure have been described above, other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily have to be in the particular order shown or in sequential order to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the apparatus, device, and non-volatile computer-readable storage medium embodiments, since they are substantially similar to the method embodiments, the description is relatively simple, and in relation to the description, reference may be made to some portions of the description of the method embodiments.
The apparatus, the device, the nonvolatile computer readable storage medium, and the method provided in the embodiments of the present specification correspond to each other, and therefore, the apparatus, the device, and the nonvolatile computer storage medium also have similar advantageous technical effects to the corresponding method.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
As will be appreciated by one skilled in the art, the present specification embodiments may be provided as a method, system, or computer program product. Accordingly, embodiments of the present description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects.
