使用这些像素坐标用于渐变标绘的地图中,随后图像将被加注普通框、图像和直线。
Using these pixel coordinates for the shaded plotted map, the image is then annotated with the usual boxes, images, and lines.
使用这些像素坐标,我们可以绘制以这些点为起点的直线,重新设定直线的颜色、连接直线、用颜色填充周围的区域或者 GD 可以执行的任何其他操作。
With these pixel coordinates, we can draw lines emanating from the the points, recolor them, connect them, fill the surrounding area with color, or anything else GD can do.
研究和改进了直线瞄准的方法,直线的定位精度可以达到0.1像素间距,并且可以测量任意位置的直线。
The method of linear aiming is researched and improved, by which, the positioning accuracy can be reached to 0.1 pixel interval and straight line in any position can be measured.
