Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure.
The color adjustment method of the graphic primitive provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the display 102 is connected to the server 104. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be located on a cloud or other network server. The server 104 obtains background color information of a background in a display interface of the display 102 and obtains primitive color information of primitives in the display interface; the server 104 determines definition information for the primitive according to the background color information and the primitive color information; the server 104 converts the current color mode into a CMYK mode and acquires K channel data of the background in the CMYK mode when the definition information does not meet the preset condition; the server 104 adjusts the K channel data of the graphic element in the CMYK mode according to the K channel data of the background in the CMYK mode, to obtain an adjusted graphic element, and displays the adjusted graphic element in the display interface of the display 102. The display 102 may be, but is not limited to, various mobile phone displays, computer displays, television displays. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.
In one embodiment, as shown in fig. 2, a method for adjusting the color of a primitive is provided, and the method is applied to the server 104 in fig. 1 for illustration, and includes the following steps:
step S202, obtaining background color information of a background in a display interface and obtaining primitive color information of primitives in the display interface.
The display interface may be a computer operation user interface provided by a display.
The background color information may be data of R, G, B channels corresponding to the background color of the display interface in the RGB mode, or may be color information corresponding to the background color in the HSL mode, the HSB mode, or the like.
Wherein, the graphic element may refer to geometric figures or characters in the display interface.
The primitive color information may be data of three channels R, G, B corresponding to the colors of the geometric figures or the characters in the RGB mode, or may be color information corresponding to the colors of the geometric figures or the characters in the HSL mode, the HSB mode and the like.
In a specific implementation, the server acquires background color information of a current background color in the display interface, and acquires color information of geometric figures or characters in the display interface.
In practical applications, the current color mode may be RGB mode, CMYK mode, HSB mode, lab mode, or the like. In addition, no matter what color mode the current color mode is, the server can acquire data of R, G, B channels corresponding to the current background color in the display interface in the RGB mode so as to obtain background color information; and acquiring data of the corresponding R, G, B three channels of the geometric figure or the text color in the display interface in the RGB mode to obtain the primitive color information.
Step S204, according to the background color information and the primitive color information, definition information for the primitive is determined.
Wherein the sharpness information may refer to contrast.
In specific implementation, the server determines the definition of the geometric figure or the text in the display interface according to the background color information corresponding to the current background color and the primitive color information corresponding to the geometric figure or the text. For example, the server determines the sharpness of the geometric figure or text in the display interface according to the data of the corresponding R, G, B three channels in RGB mode of the current background color and the data of the corresponding R, G, B three channels in RGB mode of the color of the geometric figure or text in the display interface.
In step S206, if the sharpness information does not meet the preset condition, the current color mode is converted into CMYK mode, and K channel data of the background in CMYK mode is obtained.
The color mode may be RGB mode, CMYK mode, HSB mode, lab mode, or the like.
In the specific implementation, under the condition that the definition of the geometric primitive or the text in the display interface does not meet the preset condition, the server converts the current background color, the color of the geometric figure and the color mode of the text into a CMYK mode, and then the server acquires the K value of the background color in the CMYK mode.
Step S208, according to the K channel data of the background in the CMYK mode, the K channel data of the graphic primitive in the CMYK mode is adjusted to obtain an adjusted graphic primitive, and the adjusted graphic primitive is displayed in a display interface.
In the specific implementation, the server adjusts the K value of the geometric figure or the text in the CMYK mode according to the K value of the background color in the CMYK mode to obtain the adjusted geometric figure or text, and displays the adjusted graphic element in the display interface.
In practical application, when the K value of the background color in the CMYK mode is less than 50%, the K value of the unclear primitive color is raised, and when the K value of the background color in the CMYK mode is greater than or equal to 50%, the K value of the unclear primitive color is lowered. The K value adjusting amplitude can be set to 15% -30% according to different application scenes, and when the adjusting amplitude value is larger, the color of the adjusted primitive is clearer, but the color of the adjusted primitive is more different from that of the original primitive.
For the understanding of the person skilled in the art, the first column in table 1 shows the color RGB values of several primitives before adjustment by the above method in a white background, and the second column in table 1 shows the color RGB values of the primitives after adjustment by the above method in a white background. The color of the graphic element can be obviously clearer in a white background after the color RGB value is changed by adopting the method. It should be noted that the actual colors of the primitives are not shown in the table, but the RGB values are used to represent the colors of the corresponding primitives.
TABLE 1
For the convenience of understanding of those skilled in the art, fig. 3 exemplarily provides a flowchart of a color adjustment method of a graphic primitive, which includes the steps of:
step 1: acquiring the current background color;
step 2: acquiring RGB color numbers corresponding to the primitive colors under the current background;
step 3: calculating Contrast Ratio according to the current background color and the RGB color number corresponding to the primitive color under the current background;
step 4: under the condition that the Contrast Ratio is larger than a preset threshold value, color adjustment is not performed; under the condition that the Contrast Ratio is smaller than or equal to a preset threshold value, converting the current background color and the primitive color from an RGB mode to a CMYK mode; for example, the preset threshold may be in the range of 1.2-1.35;
Step 5: judging the K value of the current background color in the CMYK mode, reducing the K value of the primitive color when the K value is greater than or equal to 50%, and increasing the K value of the primitive color when the K value is less than 50%.
The color adjustment method of the graphic primitive provided by the embodiment can be applied to application programs for displaying and editing text information such as a text reader, a text editor, a text processor, a spreadsheet, a presentation, a web browser and the like, can be applied to other application programs with text annotation and geometric graphic primitive annotation functions, and can also be applied to computer aided design.
The color adjustment method, the device, the computer equipment, the storage medium and the computer program product of the primitives are used for acquiring the background color information of the background in the display interface and acquiring the primitive color information of the primitives in the display interface; determining definition information for the graphic primitive according to the background color information and the graphic primitive color information; under the condition that the definition information does not meet the preset condition, converting the current color mode into a CMYK mode, and acquiring K channel data of the background in the CMYK mode; according to the K channel data of the background in the CMYK mode, adjusting the K channel data of the graphic primitive in the CMYK mode to obtain an adjusted graphic primitive, and displaying the adjusted graphic primitive in a display interface; therefore, when the display of the plurality of primitives is not clear enough under the current color background, the colors of the primitives are adjusted according to the definition information of the primitives, so that the primitives in the display interface can be clearly displayed, and the display definition of the primitives in the display interface under the current color background is improved.
In another embodiment, determining sharpness information for a primitive based on background color information and primitive color information includes: determining background relative brightness information according to the background color information, and determining primitive relative brightness information according to the primitive color information; and determining the contrast ratio for the graphic element as definition information according to the background relative brightness information and the graphic element relative brightness information.
The background relative brightness information may be the relative brightness of the background color.
The relative brightness information of the graphic element can be the relative brightness of the graphic element color.
The contrast may be the contrast between the relative brightness of the background color and the relative brightness of the primitive color.
In specific implementation, the server determines the relative brightness of the current background color according to the background color information corresponding to the current background color, determines the relative brightness of the geometric figure or the character according to the primitive color information corresponding to the geometric figure or the character, determines the contrast for the geometric figure or the character according to the relative brightness of the background color and the relative brightness of the geometric figure or the character, and takes the contrast as definition information. For example, the server determines the relative brightness of the background color according to the data of the corresponding R, G, B three channels in the RGB mode of the current background color, and the server determines the relative brightness of the geometric figure or the text according to the data of the corresponding R, G, B three channels in the RGB mode of the geometric figure or the text in the display interface, and the server determines the contrast for the geometric figure or the text according to the relative brightness of the background color and the relative brightness of the geometric figure or the text, and takes the contrast as the definition information.
In practical application, the contrast calculation formula between the background color and the primitive color is as follows:
Contrast Ratio=（L1+0.05）/（L2+0.05）
wherein, contrast Ratio is Contrast, L1 is relative brightness of background color, and L2 is relative brightness of primitive color.
The calculation formula of the relative brightness is as follows:
L=0.2126*R+0.7152*G+0.0722*B
wherein, L is relative brightness, R, G, B takes the following value modes: if XsRGB < = 0.03928, X = XsRGB/12.92; if XsRGB >0.03928, x= ((xsrgb+0.055)/1.055)/(2.4) (where XsRGB denotes RsRGB, gsRGB, bsRGB; xsrgb=x8bit/255, X8bit denotes the value of R, G, B channel 0-255 under 8bit channel).
The above-mentioned Contrast Ratio has a value range of 1-21, and when the Contrast Ratio is closer to 1, the color of the primitive is less clear in the current background. In practical application, when the defined Contrast Ratio is smaller than a certain value, the color of the primitive is the color which is displayed in the current background and is unclear.
According to the technical scheme of the embodiment, the background relative brightness information is determined according to the background color information, and the primitive relative brightness information is determined according to the primitive color information; determining the contrast ratio of the graphic primitive as definition information according to the background relative brightness information and the graphic primitive relative brightness information; therefore, the contrast ratio of the graphic primitive and the background can be accurately determined, and the color of the graphic primitive can be accurately adjusted.
In another embodiment, in a case where the sharpness information does not satisfy the preset condition, converting the current color mode into the CMYK mode includes: acquiring a contrast threshold; and under the condition that the contrast of the graphic primitive is smaller than or equal to a contrast threshold value, determining that the definition information does not meet a preset condition, and converting the current color mode into a CMYK mode.
The contrast threshold may be 1.3, and in practical applications, the contrast threshold may be set within a range of values from 1.2 to 1.35.
In the specific implementation, the server acquires a contrast threshold, determines that the definition information does not meet a preset condition under the condition that the contrast of the geometric figure or the text is smaller than or equal to the contrast threshold, and converts the current color mode into a CMYK mode.
According to the technical scheme, a contrast threshold value is obtained; under the condition that the contrast of the graphic primitive is smaller than or equal to a contrast threshold value, determining that the definition information does not meet a preset condition, and converting the current color mode into a CMYK mode; therefore, whether the current color mode needs to be converted or not can be accurately determined, and the color of the graphic primitive in the display interface can be adjusted quickly.
