谁能把这段英文给翻译一下(关于UF中whitesq逻辑变量的定义):This predefined symbol returns true if the x-coordinate and the y-coordinate of the pixel being calculated give an odd number when added together; otherwise, it returns false. If you think of the screen as a large checkerboard with white and black squares with the size of a single pixel, #whitesq returns true for every white pixel.
从字面上看:象素点的坐标奇、偶数是怎么定义的呢? |
