网上找不到解决方法，英文渣渣，对应的参数都是啥意思呢，对绘制有什么变化

<dict>
            <key>fuck.png</key>
            <dict>
                <key>frame</key>
                <string>{{116,2},{88,112}}</string>
                <key>offset</key>
                <string>{0,0}</string>
                <key>rotated</key>
                <true/>
                <key>sourceColorRect</key>
                <string>{{0,0},{88,112}}</string>
                <key>sourceSize</key>
                <string>{88,112}</string>
            </dict>
