本文主要是介绍mtk关机充电动画旋转90/270度后坐标计算，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
mtk6580 android6.0 720*1280分辨率，需要旋转90度（1280*720）作横屏设备使用，但是logo文件夹没有对应旋转90度的"hd720nl"文件夹动画资源支持，只有“hd720”文件夹。查看到有相似分辨率1280*800的动画资源“wxganl/”文件夹，通过win自带画图工具重新调整一下大小变成1280*720的动画资源"hd720nl"使用。
//新建hd720nl文件夹，复制wxganl文件夹内容到hd720nl文件夹，批量替换wxganl前缀名的文件为hd720nl
rename 's/wxganl/hd720nl/' wxga*.bmp1. project中的开机logo分辨率与旋转角度修改
vi device/eastaeon/xxx/ProjectConfig.mk
...
BOOT_LOGO = hd720nl
MTK_LCM_PHYSICAL_ROTATION = 90
...vi kernel-3.18/arch/arm/configs/xxx_debug_defconfig

...vi vendor/mediatek/proprietary/bootable/bootloader/lk/project/xxx.mk
...
MTK_LCM_PHYSICAL_ROTATION = 90
...//作用于lk
vi device/eastaeon/xxx/eastaeon.mk
...
BOOT_LOGO = hd720nl
...android frameworks旋转：
vi device/eastaeon/xxx/system.prop
...

2. 关机充电动画坐标计算
小技巧：打开win系统画图软件，
1).选择 查看->缩放->将图片放到到800%，
2).选择 查看->缩放->显示网格，这样就可以看到对应像素坐标了（因为logo使用bmp图片格式）

#endif
具体坐标计算如下，从对应分辨率的logo文件夹找出对应的battery logo图片放大再取对应像素点坐标：
3. 验证调试
1). android6.0 mt6580sdk提供的测试程序可以测试lk logo、kernel logo、充电动画
cd vendor/mediatek/proprietary/external/libshowlogo/libshowlogoTest//mm编译完，push到系统,例如测试充电动画
adb push xxx\operation\alps\out\target\product\xxx\system\bin\libshowlogotest sdcard///可执行程序测试
libshowlogotest charging fb new
2). 需要调试打印充电动画角度算法等
vi vendor/mediatek/proprietary/external/libshowlogo/show_logo_common.c
然后更新libshowlogo.so到系统（发现push几次so库后，测试程序运行有异常测试程序执行感觉卡卡的，重新烧录系统即可）
/mm编译完，pash到系统
adb push operation\alps\out\target\product\xxx\system\lib\libshowlogo.so /system/lib/chmod 644 /system/lib/libshowlogo.sosync
