It is plotted on interim base map.
Wherein, each word is made up of multiple pixels, and color value includes transparency component and multiple color components, temporarily
The transparency component of all pixels point and color component are 0 in base map, and word to be drawn is to wait to draw to target base map
Word.
The respective pixel of the color component of the first pixel in step 102, more interim base map and word to be drawn
The color component being pre-configured with of point whether there is difference.
Wherein, the first pixel is any pixel point being plotted on interim base map.
If step 103, the color component of the first pixel on interim base map and the corresponding pixel points of word to be drawn
The color component being pre-configured with have differences, determine the target color values of the second pixel.
Wherein, the transparency of color component of the target color values based on the first pixel and target base map obtains, the second picture
Vegetarian refreshments is the pixel corresponding with the first pixel of word to be drawn.
Step 104, draw the second pixel using target color values on target base map.
In summary, Word-Drawing method provided in an embodiment of the present invention, the first pixel on more interim base map is passed through
The color component of point and the color component being pre-configured with of the corresponding pixel points of word to be drawn whether there is difference, at both
When having differences, the transparency of color component based on the first pixel and target base map, it is determined that word to be drawn with the
The target color values of pixel corresponding to one pixel, the second pixel, phase are drawn using target color values on target base map
For correlation technique, it is determined that when the target color values of pixel of word are drawn, the face of the first pixel has been considered
The influence of colouring component and target base map so that the color for the word drawn out and expected color are closer, improve and draw out
Word color the degree of accuracy.
Fig. 2 is the flow chart of another Word-Drawing method provided in an embodiment of the present invention, as shown in Fig. 2 this method can
With including：
Step 201, using word to be drawn each pixel the color value being pre-configured with, by word to be drawn
It is plotted on interim base map.
Wherein, the color value of pixel can include transparency component and multiple color components, and the plurality of color component can
With including：Red color component, green color component and blue color component, there can also be the group of other components in practical application
Conjunction mode, such as red component and yellow color component, or red color component, green color component, blue color component and white
Colouring component, the embodiment of the present invention are not construed as limiting to this, and the transparency component of all pixels point and color component can in interim base map
To be 0, so can largely reduce influences on the color value for being plotted in pixel on interim base map.
Illustratively, it is assumed that the color value being pre-configured with of certain pixel of word to be drawn is (255,0,0), then can adopt
The pixel is plotted on interim base map with color value (255,0,0).
Step 202, acquisition are plotted in the color value of the first pixel on interim base map.
When drawing the first pixel on interim base map, first pixel is typically plotted in the neighbour for the pixel drawn
In domain, the color value of the pixel drawn may produce certain influence, the influence to the color value of the first pixel
Be usually expressed as making the color of the first pixel drawn out brighter so that the color value for the first pixel drawn out relative to
The color value being pre-configured with is less than normal, i.e., the color component of the first pixel may exist poor with the color component being pre-configured with
It is different, therefore, interim base map is plotted in, it is necessary to first obtain before the pixel of word to be drawn is plotted on target base map
On the first pixel color value, then in the color value of the first pixel on more interim base map multiple color components with
The color component being pre-configured with of the corresponding pixel points of word to be drawn whether there is difference, be determined such as further according to comparative result
Where with the first pixel corresponding pixel of to be drawn word is drawn on target base map.
The respective pixel of the color component of the first pixel in step 203, more interim base map and word to be drawn
The color component being pre-configured with of point whether there is difference.
When any color component of the first pixel is corresponding with being pre-configured with for the corresponding pixel points of word to be drawn
When color component is unequal, you can think the advance of the color component of the first pixel and the corresponding pixel points of word to be drawn
The color component of configuration has differences, and now, performs step 204；When the first pixel all colours component with it is to be drawn
During the equal correspondent equal of the color components being pre-configured with of the corresponding pixel points of word, you can think that difference is not present in both, now,
Perform step 206.
Illustratively, it is assumed that the color value of the first pixel is (128,128,2), the corresponding pixel points of word to be drawn
The color component being pre-configured with is (255,0,0), when the red color component of color value is compared, the first pixel it is red
Color color component is 128, and the red color component being pre-configured with of the corresponding pixel points of word to be drawn is 255, it is known that the
The color component of one pixel and the color component being pre-configured with of the corresponding pixel points of word to be drawn have differences, then hold
Row step 204.
If step 204, the color component of the first pixel on interim base map and the corresponding pixel points of word to be drawn
The color component being pre-configured with have differences, determine the target color values of the second pixel.
Because the transparency that target color values are color component and target base map based on the first pixel obtains, because
This, obtained target color values have considered the influence of the color component and target base map of the first pixel, itself and target bottom
The contrast of figure is less than the color value of the first pixel and the contrast of target base map.Alternatively, target color values can include：
Target clear degree component.Specifically, as shown in figure 3, determining the process of the target color values of the second pixel, can include：
Step 2041, the transparency component for obtaining target base map.
Because Word-Drawing method provided in an embodiment of the present invention is by Word-Drawing to the target bottom for having drawn image
On figure, and the transparency component of the pixel in the image of the target base map for having drawn image and color component are
Know, therefore, the mode such as transparency component that can be by detecting pixel obtains the transparency component of target base map.Illustratively,
Assuming that the transparency component of the target base map obtained is 191.
Step 2042, the transparency component for obtaining the first pixel.
Alternatively, the transparency component of the first pixel can determine according to the color component of the first pixel, specifically,
The average value of the plurality of color component can be determined according to multiple color components of the first pixel, it is then, the average value is true
It is set to the transparency component of the first pixel.
Illustratively, it is assumed that the color value of the first pixel is (128,128,2), can obtain the average value of 3 color components
For (128+128+2)/3=86, then average value 86 can be defined as to the transparency component of the first pixel, that is, the first picture obtained
The transparency component of vegetarian refreshments is 86.
Step 2043, target clear determined according to the transparency component of target base map and the transparency component of the first pixel
Spend component.
Specifically, the transparency component of transparency component that can be based on target base map and the first pixel, according to target
Transparency component calculation formula determines target clear degree component, and the target clear degree component calculation formula is：TargetA=(1-
(1-textA/255)*(1-backA/255))*255。
Wherein, TargetA is target clear degree component, and textA is the transparency component of the first pixel, and back A are mesh
The transparency component of base number of a tender figure.
Illustratively, it is assumed that the transparency component backA of target base map is 191, the transparency component textA of the first pixel
For 86, then target clear degree component TargetA=(1- (1-86/255) * (1-191/255)) * 255=213.
Step 2044, judge whether target clear degree component is more than the first color component.
Wherein, the first color component is any color component in multiple color components of the first pixel, be that is to say, this
One color component can be any one in red color component, green color component or blue color component.
It is alternatively possible to determine the target face of the second pixel jointly according to target clear degree component and the first color component
Colour, the target color values of the determination collectively constitute the mesh of the second pixel with the target clear degree component determined in step 2043
Mark color value.Specifically, it can be determined that whether target clear degree component is more than the first color component, when target clear degree component is big
When the first color component, step 2045 is performed, when target clear degree component is not more than the first color component, performs step
2046。
Illustratively, it is assumed that the first color component is 128, and target clear degree component is 213, and target clear degree component is more than the
One color component, then perform step 2045.
Step 2045, when target clear degree component is more than the first color component, target clear degree component is defined as
One color of object component.
Wherein, first object color component is color of object corresponding with the first color component in multiple color of object components
Component.
When target clear degree component is more than the first color component, illustrate target clear degree component closer to being pre-configured with
Color component, therefore, the target clear degree component can be defined as first object color component, to reduce the word drawn out
The difference of color and expected color.
Illustratively, it is assumed that the first color component is 128, and target clear degree component is 213, and target clear degree component is more than the
Target clear degree component, then can be defined as first object color component by one color component, i.e. first object color component is
213。
From the foregoing, it will be observed that the color component being pre-configured with of certain pixel of word to be drawn is 255, interim bottom is plotted in
Corresponding first color component of the first pixel on figure is 128, and corresponding first object color component is 213, relative to
The first color component being plotted on interim base map, the closer color component being pre-configured with of the first object color component, when
When pixel is plotted on target base map using the color component, the color for the word drawn out can be reduced with being pre-configured with
Color difference.
Step 2046, when target clear degree component is not more than the first color component, the first color component is defined as
One color of object component.
When target clear degree component is not more than the first color component, illustrate the first color component closer to being pre-configured with
Color component, therefore, first color component can be defined as first object color component, to reduce the face for the word drawn out
Color and the difference of expected color.
Illustratively, it is assumed that the first color component is 228, and target clear degree component is 213, and target clear degree component is less than the
One color component, then the first color component can be defined as to first object color component, i.e. first object color component is 228.
In practical application, it is determined that the process of the target color values of the second pixel, can only include step 2041 to step
Rapid 2043, it that is to say, target only can be determined according to the transparency component of target base map and the transparency component of the first pixel
Transparency component, multiple color components of the target clear degree component of the determination and the first pixel are then defined as the second picture
The target color values of vegetarian refreshments, to reduce the difference of the color for the word drawn out and expected color to a certain extent.
In practical application, step 2044 can be performed both by each color component of the first pixel to 2046, it is of the invention
Embodiment simply illustrates by taking the first color component as an example, the color of object component of other color components in the first pixel
Determination process may be referred to the determination process of first object color component, the embodiment of the present invention is not repeated this.
Step 205, draw the second pixel using target color values on target base map.
The target face of the second pixel is determined in the transparency of the color component according to the first pixel and target base map
After colour, the second pixel can be drawn according to the target color values of the determination.
Illustratively, it is assumed that on the target base map (its color value is (0,0,0)) of white, each picture of word to be drawn
The color being pre-configured with of vegetarian refreshments is black (its color value is (255,255,255)), using the Word-Drawing of correlation technique
The schematic diagram for the word that method is drawn out according to the color value being pre-configured with target base map refer to Fig. 4, using the present invention
The schematic diagram for the word that the Word-Drawing method that embodiment provides is drawn out according to the color value being pre-configured with target base map
Fig. 5 is refer to, can be obtained according to Fig. 4 and Fig. 5 contrast, is occurred on the word drawn out using the Word-Drawing method of correlation technique
The shade of one layer of black, and the color for the word drawn and the color value that is pre-configured with differ greatly, the embodiment of the present invention
Almost there is no shade on the word that the Word-Drawing method of offer is drawn out, and the color for the word drawn and the face that is pre-configured with
The difference of colour is smaller, therefore, the color for the word drawn out using Word-Drawing method provided in an embodiment of the present invention with it is pre-
The color of phase is closer, improves the degree of accuracy of the color for the word drawn out.
If the corresponding pixel points of the color component of step 206, the first pixel and word to be drawn are pre-configured with
Difference is not present in color component, and the second pixel is drawn using the color value of the first pixel on target base map.
The color component being pre-configured with of the corresponding pixel points of the color component of first pixel and word to be drawn is not
Have differences, that is to say, the color component of the first pixel and the face being pre-configured with of the corresponding pixel points of word to be drawn
Colouring component correspondent equal, when drawing word according to the color component, influence of the target base map to the word of drafting can reduce
To minimum, it is therefore possible to use the color value of the first pixel directly draws the second pixel on target base map.
In practical application, each pixel that can treat the word of drafting is performed both by step 201 to 206, and the present invention is real
Apply example simply to illustrate by taking the first pixel as an example, the drawing process of other pixels of word to be drawn may be referred to the
The drawing process of one pixel, the embodiment of the present invention are not repeated this.
In summary, Word-Drawing method provided in an embodiment of the present invention, the first pixel on more interim base map is passed through
The color component of point and the color component being pre-configured with of the corresponding pixel points of word to be drawn whether there is difference, at both
When having differences, the transparency of color component based on the first pixel and target base map, it is determined that word to be drawn with the
The target color values of pixel corresponding to one pixel, the second pixel, phase are drawn using target color values on target base map
For correlation technique, it is determined that when the target color values of pixel of word are drawn, the face of the first pixel has been considered
The influence of colouring component and target base map so that the color for the word drawn out and expected color are closer, improve and draw out
Word color the degree of accuracy.
