69 <p>放大镜对您的鼠标指针周围区域进行了放大显示。</p>
70 <img src="../images/apps-images/magnify.png" alt="magnify.png" />
71 <p>在顶部,您可以找到该区域的尺寸和放大倍数。 "<i>32 x 32 @ 8 pixels/pixel</i>" 表示,您正在查看鼠标周围 32x32 的像素面积,而且每个像素都放大了8倍。</p>
72 <p>下面是一个具有红色轮廓的的像素。它的颜色以RGB和十六进制值表示。<br />
73 您可以使用 <span class="key"></span> / <span class="key"></span> / <span class="key"></span> / <span class="key"></span> 移动红色的轮廓。</p>
74 <p>为了量度距离和排列的对象,您可以使用 <span class="key">ALT</span> <span class="key">H</span> 添加两个蓝色的十字丝。它们的 X/Y 坐标趋向于左上角,如果添加了两个十字丝,它们的之间的 X/Y 距离显示于窗口的底部。
76 <br />
77 十字丝也可以通过 <span class="key"></span> / <span class="key"></span> / <span class="key"></span> / <span class="key"></span> 进行移动,而活动的十字丝则标记为 "x"</p>
78 <p>您可以使用 <span class="key">OPT</span> <span class="key"></span> / <span class="key"></span> / <span class="key"></span> / <span class="key"></span> 控制鼠标指针,使指针以像素为单位移动。</p>
79 <p>点击弹出菜单将会给出下面的选项:</p>
