Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.
Fig. 1 is the schematic flow chart of the generation method of the palette of one embodiment of the application.Method shown in FIG. 1
Executing subject can be, but not limited to mobile phone, computer and other intelligent terminals.Or the executing subject of method shown in FIG. 1 is also
It can be and be able to carry out client of this method itself, such as method shown in FIG. 1 is executed by the generating means of palette.
As shown in Figure 1, determining the mass-tone of palette at S102.
Palette by a series of there is certain representative basic color and their gradient color to form, and user is in palette
In can find the color of needs and obtain color value.
Producing principle based on palette can determine the mass-tone of toning analysis first.It should be pointed out that mixing colours determining
While the mass-tone of plate, the number (mass-tone number) of mass-tone can be determined simultaneously.
For example, user can choose a mass-tone as No. 5 colors.The specific color of mass-tone can be chosen by user.
At S104, number based on a specified passes through the determining ratio value corresponding with specified number of Bezier.
Specified number can be pre-set number.For example, pre-set number can be 1 to 9, wherein No. 5
Color is mass-tone.
Bezier realizes the smooth transition of curve, and the more, then curve transition is further smooth for the point on curve.
Specified number can be associated with ratio value by Bezier, as a result, number based on a specified, it can
To uniquely determine a corresponding ratio value by Bezier, thus number based on a specified, can more it is smooth really
Certainty ratio value.
For example, the corresponding ratio value determined can then seamlessly transit for number 1 to 9.
At S106, the size relation based on a specified numbered between the number of mass-tone determines blend color.
Mass-tone plate generally includes light-colored part and dark parts are total to two parts colour table.For light-colored part colour table, mainly
Mass-tone is mixed with white.For dark parts colour table, mainly mass-tone is mixed with black.Here white with
Black is blend color.
Herein, it should be pointed out that blend color is also possible to other colors, especially for dark parts colour table,
Blend color is not limited to black, can also generate blend color based on mass-tone.
It is further noted that typically, when specified number is less than or equal to the number of mass-tone, this is specified
Part be usually light-colored part colour table number, when specified number is greater than the number of mass-tone, the specified number is usual
For the number of dark parts colour table.Therefore, the size relation between number and the number of mass-tone based on a specified, can determine mixed
Close color.
For example, for the palette including number 1 to 9, No. 5 colors are mass-tone, then 1 to No. 4 is light-colored part colour table, 6 to 9
Number be dark parts colour table.
At S108, it is based on mass-tone, ratio value and blend color, generates palette.
Based on the brightness of the adjustable blend color of ratio value, then mass-tone and blend color adjusted are mixed
It closes, generates corresponding palette.
For each number on palette, ratio corresponding with the number specified can be determined by Bezier
Value, the characteristic based on Bezier, ratio value can number smooth transitions based on a specified；By ratio value, mass-tone and mix
After closing color generation palette, palette can have the characteristic of Bezier based on ratio value, make the transition of color range can more
Harmony, this is it is avoided that the form and aspect of depth part are imperfect in the palette that the superposition of equal proportion results in, especially dark color portion
The partially grey problem of the color divided.
In some embodiments, Bezier can be indicated by the polynomial form of Bornstein substrate of n rank, base
In practical application, the value of n can preferably be limited between 1 to 10 here, this implementation is not specific to the value work of n, n value
Size has no effect on the specific implementation of the present embodiment.
Fig. 2 is the schematic diagram that ratio value is determined by Bezier of one embodiment of the application.As shown in Fig. 2, figure
In Bezier can be drawn based on parameter 0.26,0.09,0.67,0.73.0.26 correspond to parameter ctx, 0.09
Correspond to parameter end corresponding to parameter start, 0.67,0.73 corresponds to parametric curvature.
For the above parameter, Bezier can be generated by such as minor function, it may be assumed that
*@param{CanvasRenderingContext2D}ctx；
*@param { Array<number>} start starting point；
*@param { Array<number>} end terminal；
*@param { number } curveness curvature (0-1)；
*/function drawCurvePath(ctx,start,end,curveness){}；
The horizontal axis coordinate of the Bezier of generation can indicate that the number of palette, ordinate of orthogonal axes can indicate and mix colours
Ratio value corresponding to the number of plate.
Based on Fig. 2 it is found that in number based on a specified, pass through the determining ratio corresponding with specified number of Bezier
It when value, based on a specified can number, determine the horizontal axis coordinate point in the two-dimensional coordinate system where Bezier；Based on horizontal axis
Coordinate points can be determined the ratio value on the longitudinal axis corresponding with horizontal axis coordinate point by Bezier.
Wherein, the distance between two numbers of arbitrary neighborhood are identical in Fig. 2.It is further noted that here
Horizontal axis and the longitudinal axis are in contrast, can to carry out the conversion on position based on the positional relationship of itself therebetween, such as can be with
Convert horizontal axis with the longitudinal axis for 90 degree of the two rotating Vortex, but this has no effect on the realization of the present embodiment.
Optionally, as an example, it is being based on horizontal axis coordinate point, is being determined by Bezier corresponding with horizontal axis coordinate point
The longitudinal axis on ratio value when, can be based on horizontal axis coordinate point, determine by horizontal axis coordinate point and perpendicular to the straight line of horizontal axis with
The intersection point of Bezier；Based on intersection point, ratio value corresponding with intersection point on the longitudinal axis can be determined in two-dimensional coordinate system.
Specifically, No. 6 colors in Fig. 2 are mass-tone, the corresponding ratio value of No. 1 color is 7.6%, indicates that No. 1 color subtracts light 93%；
The corresponding ratio value of No. 6 colors is 100%, indicates that mass-tone subtracts light 0%.
Optionally, as an example, when determining blend color, white can be determined as to the mixed of light-colored part colour table
Color is closed, i.e., when specified number is less than or equal to the number of mass-tone, white is determined as blend color.And for light portion
The blend color of color separation plate then can be adjusted mass-tone to form blend color, specifically, when specified number is greater than master
When the number of color, the color after mass-tone can be adjusted to HSB value is determined as blend color.
When being adjusted to mass-tone, it can be based on HSB model, corresponding form and aspect rotation is carried out to mass-tone and deepens brightness value
To generate blend color.The color of the palette obtained in this way, dark parts colour table will not be partially grey, can promote whole visual impression
Feel.
In HSB model, H indicates form and aspect (H, hue).In 0~360 ° of standard colour wheel, form and aspect are opsition dependent measurements.
It is such as red, green or orange common in use, form and aspect are identified by color designation.Black and white is without form and aspect.
S indicates the purity (S, saturation) of color, is grey when S is 0.White, black and other grey colors all do not have
Saturation degree.In maximum saturation, each form and aspect have most pure coloured light.S value range 0~100%.
B indicates brightness (B, brightness), is the brightness of color.As black when B is 0.Maximum brightness is color
Most distinct state.S value range 0~100%.
RGB represents the color in three channels of red, green, blue, the excessively variation to red (R), green (G), blue (B) three Color Channels
And the available miscellaneous color of their mutual superpositions.Therefore, any one mass-tone can pass through the shape of RGB
Formula is indicated.
Any one can indicate that form and aspect rotation is exactly on the three-dimensional space in three-dimensional space by the color that RGB is indicated
RGB point rotate a certain angle around by the perpendicular bisector of 3 points of planes constituted of RGB.
When being adjusted to mass-tone, can the cold and warm tone based on color corresponding form and aspect rotation is carried out to mass-tone and is deepened
Brightness value.Specifically, the form and aspect of mass-tone can be rotated to the first predetermined angle counterclockwise, and will lead when mass-tone is warm colour
The brightness value of color deepens the first preset ratio；When mass-tone is cool colour, the form and aspect of mass-tone are rotated clockwise into the second predetermined angle,
And the brightness value of mass-tone is deepened into the second preset ratio.
When mass-tone is different cold and warm tone, the above different strategy is executed to carry out corresponding form and aspect rotation to mass-tone
And deepen brightness value, it may be implemented to carry out targetedly form and aspect rotation to the most dark value of the mass-tone of cold-warm color, to be promoted
Color vision effect.
Wherein, the first predetermined angle can be 26 degree, and the first preset ratio can be 50%；Second predetermined angle can be
10 degree, the second preset ratio can be 55%.These values can make the B value maximum value in the HSB model of blend color, i.e. B
It is 100%.Wherein, B value is the optimal selection that maximum value is this implementation, and B value may be other different values, at this
Within the scope of the realization of embodiment.It should be pointed out that the above specific value be the present embodiment determines according to actual conditions
Preferred value, the present embodiment are not limited to the specific restriction to values above, and the first predetermined angle is also possible to the second predetermined angle
Others value, the first preset ratio and the second preset ratio are also possible to other values.
