Embodiment 1
The embodiment of the present invention provides a kind of electronics paintbrush generation method, and as shown in Figure 1, the method comprises:
Polygonal shape can be determined by the polygonal apex coordinate of user input, and for example, if the user wants a self-defined polygon paintbrush shape as shown in Figure 2, the user will input the coordinate information on four summits of A, B, C, D.
The apex coordinate of inputting due to the user just is used for definite polygonal shape, and polygonal size is to be determined by developed width.Therefore the not restriction of polygon size that consists of of each summit of providing of user is as long as each summit is by connecting in turn the shape that can consist of the defined polygon paintbrush of user.
Further, as shown in Figure 3, determine that according to the polygon vertex coordinate of user's input the polygon of arbitrary shape, arbitrary size comprises following substep:
For example, the polygonal apex coordinate of user's input is (657,157), (621,200), (683,220), (696,181), polygonal center are actually and can choose arbitrarily, the application with polygonal center of gravity as the center, according to above-mentioned 4 apex coordinates, can obtain polygonal centre coordinate and be (664.25,189.5).
The polygon vertex coordinate comprises horizontal ordinate and two skews of ordinate with respect to the off-set value at described center, for example, according to above-mentioned 4 apex coordinates and the centre coordinate determined, the off-set value on each summit of determinate multitudes limit shape is (7.25 ,-32.5), (43.25,10.5), (18.75,30.5), (31.75 ,-8.5).
The actual coordinate on polygonal each summit can be determined according to off-set value and the developed width on centre coordinate, each summit, here original width is determined by the skew with respect to the center, the width weights that arrange by the periphery change original width, the developed width of wanting to reach the user.
Need to prove, polygonal position is that centre coordinate is determined by the position of central point, and polygonal shape is by the skew decision at each relative center, summit, and polygonal size is determined by developed width.
Further, as shown in Figure 3, according to described polygon, calculate the color weight of each pixel of described polygonal external frame, obtain the polygon paintbrush, specifically comprise following substep:
Polygonal external frame is the square that comprises polygonal level minimum, determines according to the coordinate of the pixel on polygonal limit.This square is comprised of the pixel of several row of several row, because in computer system, the unit of coordinate is pixel, so these foursquare four apex coordinates are all integers.
Generally, after polygonal shape and size are determined, when a polygon translation integer coordinate time, the also same distance of translation accordingly of its square external frame so, this moment, the relative position of polygon and its external frame did not change, so the weights of each pixel in external frame do not change.So in the situation that polygonal shape and size determine, when the fraction part of center coordinate is determined, and whole polygonal shape is determined, the weights of each pixel of so external frame just can uniquely have been determined.
Need to prove, the pixel weight storage with polygonal external frame becomes template in advance, stores the weights of all pixels in an external frame with an array, wherein, and the weights of the corresponding pixel of an element in array.
When actual storage, the precision set of the fraction part of transverse and longitudinal coordinate is 0.25, be that transverse and longitudinal coordinate fraction part respectively has 0,0.25,0.5,0.75 four kind, so in the certain situation of width, the centre coordinate that is determined by fraction part has 16 kinds of positions, can search immediate that template of fraction part of centre coordinate when reading template.
4 apex coordinates that above-mentioned user sets are asked the template of paintbrush, and store in internal memory and go, particularly, set take 0.25 as the interval, its centre coordinate has 16 kinds of positions, is respectively:
(100，100)，(100，100.25)，(100，100.5)，(100，100.75)；
(100.25，100)，(100.25，100.25)，(100.25，100.5)，(100.25，100.75)；
(100.50，100)，(100.50，100.25)，(100.50，100.5)，(100.50，100.75)；
(100.75，100)，(100.75，100.25)，(100.75，100.5)，(100.75，100.75)；
Here, 100 in 16 centre coordinates is the integers that there is no practical significance, only uses fraction part wherein when concrete the application.
Particularly, as shown in Figure 4, in the situation that the shape of polygon paintbrush and size are certain, the obtaining by following substep of the color weight of each pixel in the external frame of polygon:
Particularly, whether judgement (x, y) is at described outside of polygon, be actually judgement take (x, y) as starting point ray and total number of polygon intersection point whether be even number, when total number of intersection point is even number, illustrate that (x, y) is for the point of outside of polygon; When total number of intersection point is odd number, illustrate that (x, y) is the point of polygon inside;
Step 404 when described polygon is inner, is calculated the coordinate of described pixel to described polygonal distance when the coordinate of described pixel;
Particularly, calculate the coordinate of described pixel to described polygonal each back gauge, the coordinate of determining described pixel minimum distance in described polygonal each back gauge, the distance of described minimum are that the coordinate of described pixel is to described polygonal distance.
Wherein, described preset value rule of thumb can select 6, perhaps other positive integers, and this value has determined the color depth on the border of paintbrush.
Can determine to form the weights of each pixel of described external frame according to said method.The weights of each pixel in the polygonal external frame that calculates just form the array that ranks equate.In the situation that developed width is certain, a center can so just can obtain 16 arrays in the hope of the array of a correspondence, and it is saved in internal memory.
When reading, fraction part and the developed width size of the centre coordinate that obtains according to actual computation, template corresponding to inquiry in internal memory.For example, actual centre coordinate is (200.07,321.46), fraction part in horizontal ordinate is 0.07 and 0.0 the most approaching, and the fraction part of horizontal ordinate gets 0.0 so, and the fraction part of ordinate is 0.46 and 0.5 the most approaching, the fraction part of ordinate gets 0.5 so, search template corresponding to (0.0,0.5) in 16 templates of storing again from internal memory, just can obtain the weights of each pixel of corresponding external frame.
RGB (red, green, blue) value is for using the RGB model to be the colouring intensity value in 0 to 255 scope of RGB component distribution of each pixel in image.The rgb color pattern is to obtain color miscellaneous by variation and their stacks each other to red (Red), green (Greed), blue (Blue) three Color Channels.
The polygon paintbrush that consists of according to the rgb value of each pixel as shown in Figure 5, the paintbrush design sketch in figure is the design sketch after amplifying 8 times.
