Click Replace to replace all instances of the setting. 8 Open phpmyadmin and import the altered file.1 Open a text editor th at doesnt do rich text formatting, such as Notepad, and type the opening PHP tag: ?php. 2 Write a B¨¦zier function for drawing cur ves. The GD function library doesnt include such a function, so create your own See Resources. The following function uses the GD font styles function imagesetpixel, which sets a pixel at the coordinates specified by the second and third parameters. The fourth parameter s pecifies the color and, as with most GD functions, the first parameter is an image identifier.function bezier&img, x, y, color, re Bio Limousin Moteur de recherche scx = 3*x[1] - x[0];bx = 3*x[2] - x[1] - cx;ax = x[3] - x[0] - cx - bx;cy = 3*y[1] - y[0];by = 3*y[2] - y[1] - cy;ay = y[3] - y[0] .
nitialized to be 200 by 200 pixels, using the imagecreate function, which also creates the image identifier img. The colors red an d white are initialized with the imagecolorallocate function by specifying the values from 0 to 255 for red, green and blue. The f irst color initialized will become the background color.img = imagecreate200, 200;white = imagecolorallocateimg, 255, 255, 255;red = imagecolorallocateimg, 255, 0, 0; 4 Create two arrays for the x- and y-coordinates of the four points that will determine the s house icon hape of the B¨¦zier curve. To specify the shape of the curve, think in terms of two tangent vectors, whose magnitude determines th e amount of sway the vectors direction has over the curve, much like the path of a falling ball in a strong wind. The first of the Bio Limousin Moteur de recherche four points specifies one of the endpoints of the curve and the tail of the first vector, and the second specifies the head of th .
le, the four points are 100, 40, 150, -10, 250, 80 and 100, 180, where the upper, left corner of the image is 0, 0. The x-coordina tes for the endpoints are both 100, which centers them in the canvas from left to right. The y-coordinates indicate the first endp oint at 40 is above the other at 180. The vector heads are both above and to the right of their respective endpoints. Separate the x- and y-coordinates into their own arrays:x_coords = array100, 150, 250, 100;y_coords = array40, -10, 80, 180; 5 Draw the curve customer service resume with the B¨¦zier function created in Step 2. In the example function, the first parameter is the image identifier; the next two pa rameters are the arrays for the x- and y-coordinates; the fourth is the color; and the last is the resolution. The resolution para Bio Limousin Moteur de recherche meter determines the number of points to be plotted, so specify larger numbers for well defined curves. For example, type:bezierim .
