本申请图形渲染领域，尤其涉及窗口渲染技术。
背景技术
随着显示技术的发展，高分辨率的显示屏幕被越来越多的应用在各类终端上。但是，由于高分辨率的增大，带来了的渲染和显示的运算量的增加，从而造成了系统资源和功耗的增加。因此，在一些场景下，为了减少系统资源的占用以及降低功耗，会将一些应用按照低于系统原始分辨率的分辨率进行渲染，一般的，会采用在特定时间段内，或者特定应用运行中降低逻辑分辨率从而达到降低功耗和减少渲染计算了的目的。系统原始分辨率是指操作系统渲染窗口使用的默认分辨率。
在另一些显示技术中，为了提升渲染细节，提高图像的显示质量，会采用高于系统原始分辨率的分辨率进行渲染。例如，在3D图像的渲染时，采用高于系统原始分辨率的分辨率进行渲染，在缩放成系统原始分辨率，可以减低3D图形渲染时多边形产生的锯齿效应，提高显示效果。
可见，现有的渲染技术中会采用与系统原始分辨率不同的分辨率进行渲染。但是，当采用与系统原始分辨率不同的分辨率进行渲染时，由于窗口设计等原因，往往会产生兼容性问题，导致用户体验不好。

图4为本发明的又一种实施例的方法流程图；
图5为本发明的一种实施例的装置逻辑结构示意图；
图6为本发明的一种实施例的装置硬件结构示意图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
以图1为例介绍本发明实施例提供的执行窗口渲染方法的终端的逻辑结构。该终端可以是具体可以为一智能手机。如图1所示，该终端设备的硬件层包括CPU、GPU等，当然还可以包括存储器、输入/输出设备、内存、内存控制器、网络接口等，输入设备可包括键盘、鼠标、触摸屏等，输出设备可包括显示设备如LCD、CRT、全息成像(Holographic)、投影(Projector)等。在硬件层之上可运行有操作系统(如Android等)以及一些应用程序。核心库是操作系统的核心部分，包括输入/输出服务、核心服务、图形设备接口以及实现CPU、GPU图形处理的图形引擎(Graphics Engine)等。图形引擎可包括2D引擎、3D引擎、合成器(Composition)、帧缓冲区(Frame Buffer)、EGL等。除此之外，该终端还包括驱动层、框架层和应用层。驱动层可包括CPU驱动、GPU驱动、显示控制器驱动等。框架层可包括图形服务(Graphic Service)、系统服务(System service)、网页服务(Web Service)和用户服务(Customer Service)等；图形服务中，可包括如微件(Widget)、画布(Canvas)、视图(Views)、Render Script等。应用层可包括桌面(launcher)、媒体播放器(Media Player)、浏览器(Browser)等。
在本发明实施例中，结合图1所述场景，窗口的渲染是通过系统服务中的窗口管理服务(WindowsMangerService)以及图形服务中的的SurfaceFlinger服务完成的。
为了更方便的理解本发明实施例中的内容，下面首先对本发明中重要的术语进行解释：
主窗口：是用于显示游戏或者应用的主页面的窗口。例如，在安卓系统中，如果一个应用的主活动(activity)窗口没有对应的子表面视图(surfaceview)窗口，则他的主画面窗口就是主activity窗口；如果一个应用的主activity窗口有一个继承的子surfaceview窗口，那么这个应用是使用了surfaceview窗口的，则他的主画面窗口就是这个子surfaceview窗口。
辅助窗口：除所述的主窗口外，其他窗口均可以是辅助窗口。在现有的应用显示中，常常在主窗口上叠加显示辅助窗口，从而进行一些额外信息的显示。例如在手机游戏中，叠加显示新的窗口或者第三方辅助程序窗口；或者在视频播放器中叠加显示其他信息窗口等。由于这些新的窗口往往是基于系统原始分辨率进行设计的，当采用不同于系统原始分辨率进行渲染后，这些新的窗口容易出现由于分辨率不兼容而出现各类显示错误问题。在本实施例的一些具体的实现方式中，将辅助窗口限制为除主窗口外且被标记了的窗口，在这种情况下，辅助窗口特指除主窗口外的可能出现兼容性问题的窗口。
在本发明的一些实施例中，为了更贴近实际程序的实现，通过第一窗口和第二窗口的划分，来区别主窗口和辅助窗口。其中第一窗口对应的是前述中的主窗口，而第二窗口对应的是前述实施例中的辅助窗口。
结合图2，是本发明的一种实施例的方法流程图。该实施例包括：
S201、获取窗口信息。
窗口是指应用或者游戏要进行显示的窗，所述窗口信息包括用于识别窗口是否为主窗口的信息，例如窗口的标题名(titlename)，窗口之间的继承关系，窗口的标识或者窗口的类型等。
窗口包括至少一个主窗口和至少一个辅助窗口。获取窗口信息，可以是一次性的获取多个包含了主窗口和辅助窗口的窗口，并按照后续步骤进行渲染；也可以分多次获取，每次获取一个或者多个窗口信息，并在每次获取后均按照后续步骤进行处理。
S202、对所述窗口的内容进行渲染，其中，按照第一分辨率对所述辅助窗口的内容进行渲染，按照第二分辨率对所述主窗口的内容进行渲染。
根据获取窗口信息，可以判断窗口中的主窗口和辅助窗口。在一种可能的实现方式中，现根据窗口信息确定窗口中各窗口的类型，再根据所述各窗口之间的继承关系，确定主窗口，将除主窗口之外的其他窗口作为辅助窗口。例如，在安卓系统下，在为每一个窗口创建对应的窗口状态的时候，根据该窗口的标题名titlename先识别出该窗口的具体类型。进一步的，可以根据窗口之间的父子关系识别那一个窗口是应用的主画面窗口。如果一个应用的主活动窗口没有对应的子表面视图窗口，则则他的主画面窗口就是主activity窗口；如果一个应用的主activity窗口有一个继承的子surfaceview窗口，那么这个应用是使用了surfaceview窗口的，则他的主画面窗口就是这个子surfaceview窗口。
在另一种可能的实现方式中，窗口信息中包含辅助窗口标记，根据该辅助窗口标记，可以识别出辅助窗口，从而将未进行标记的窗口作为主窗口。
在另一种可能的实现方式中，窗口信息中包含主窗口标记，根据该主窗口标记，可以识别出主窗口，从而将未进行标记的窗口作为辅助窗口。
对主窗口的内容按照第二分辨率进行渲染，第二分辨率是不同于系统原始分辨率的分辨率。一般而言，系统原始分辨率是根据终端设备的显示设备进行设置的，与显示设备进行适配。系统中的应用在运行时，默认都会按照原始系统原始分辨率进行渲染。在 本发明实施例中，主窗口按照第二分辨率进行渲染，可以实现更加灵活的效果。在一些实现方式中，按照低于系统原始分辨率的分辨率进行渲染时，可以减少系统资源的消耗和降低系统功耗；在另一些实现方式中，按照高于系统原始分辨率进行渲染时，可以提高图像渲染精度，提升图形细节(例如对于3D图形按照高于系统原始分辨率进行渲染后再按照系统原始分辨率进行绘制，可以有效的降低锯齿)。
对辅助窗口的内容按照第一分辨率进行渲染，第一分辨率是不同于第二分辨率的分辨率。即，辅助窗口的内容采用与主窗口内容所不同的分辨率进行渲染。由于第二分辨率采用与系统原始分辨率进行渲染，而辅助窗口往往并没有基于第二分辨率进行设计，从而如果辅助窗口也按照第二分辨率进行渲染，容易造成兼容性的问题。因此，将辅助窗口按照不同于第二分辨率的第一分辨率进行渲染，从而减少了兼容性问题的出现。
第一分辨率可以是比第二分辨率在渲染辅助窗口时兼容性更好的分辨率。在一种实现方式中，第二分辨率比第一分辨率更接近原始分辨率，从而使得第二分辨率的兼容性比第一分辨率好，在另一种实现方式中，第一分辨率可以是系统原始分辨率，从而具有更好的兼容性。
当第一分辨率或者第二分辨率不同于原始分辨率时，对其对应的窗口进行渲染时，其方式可能不同于按照系统原始分辨率对窗口进行渲染。例如，如图3所示在安卓系统下，本方法实施例提供一种可能的采用非系统原始分辨(即fake size)率对窗口进行渲染的方法：
1)应用向WMS申请创建窗口，WMS对每一个窗口创建一个windowstate、windowstateanimate等关键类，同时把这些类加到窗口管理器WindowsManager中统一管理。此时，这些类中并没有窗口的尺寸数据。
2)在布局的时候触发窗口尺寸的计算过程，在WMS进行尺寸计算的时候，按照非系统原始分辨率进行尺寸计算，得到非系统默认尺寸，即fake size。
3)将这个fake size传给surfaceflinger，让其按fakesize这个尺寸创建一个窗口对应的layer和相应的buffer。
4)通过返回surface control给WMS以及将surface返回给应用，从而使得将要显示的fake size回传给应用。由此，应用就会按fake size准备要显示内容
5)应用按fake size准备一帧内容，并把内容放在BufferQueue中传给SurfaceFlinger进行统一合成。
6)SurfaceFlinger将BufferQueue里面的信息给HWC进行合成，最后送显。在这个过程会把显示尺寸恢复到系统的默认尺寸。
通过以上步骤，将按照fake size准备的一帧的内容按照系统默认尺寸显示，从而将在非系统原始分辨率下渲染的内容进行了显示。
通过本方法实施例，可以使得主窗口在采用更加灵活的第二分辨率进行渲染的情况下，辅助窗口采用兼容性更好的第一分辨率进行渲染，从而在降低系统资源占用和功耗(当第二分辨率低于系统原始分辨率)或者提高渲染精度(当第二分辨率高于系统原始分辨率)的情况下，提高了辅助窗口显示时的兼容性。
结合图4，是本发明的又一实施例的方法流程图，在本实施例中，以安卓系统为例， 提供了一种窗口渲染的方法。该方法包括：
S401、准备窗口内容。
窗口内容系统通过是通过WMS进行管理的，应用增加一个窗口，则WMS为该窗口创建相应的窗口状态(WindowState)。
S402、识别当前窗口是否为主窗口。
安卓系统下，一个应用包括很多窗口如Activity主窗口和SurfaceView子窗口等。当WMS为每一个窗口创建对应的WindowState的时候，根据该窗口的titlename先初步识别出该窗口的具体类型。再根据窗口之间的父子关系识别那一个窗口是应用的主画面窗口。如果一个应用的主活动窗口没有对应的子表面视图窗口，则则他的主画面窗口就是主activity窗口；如果一个应用的主activity窗口有一个继承的子surfaceview窗口，那么这个应用是使用了surfaceview窗口的，则他的主画面窗口就是这个子surfaceview窗口。
S403、如果当前窗口为主窗口，则按照不同于系统原始分辨率的分辨率进行内容渲染。
S404、如果当前窗口不是主窗口，则按照系统原始分辨率进行内容渲染。
具体的渲染方式可参照前一实施例中介绍的渲染方法。
通过本实施例，在判断当前窗口为主窗口是才按照不同于系统原始分辨率的分辨率进行渲染，否则则按照系统原始分辨率进行渲染。从而在降低系统资源占用和功耗(当第二分辨率低于系统原始分辨率)或者提高渲染精度(当第二分辨率高于系统原始分辨率)的情况下，提高了非主窗口显示时的兼容性。

在另一种实施方式中，窗口信息包含了辅助窗口标记，辅助窗口标记用于标识待渲染窗口为辅助窗口，处理单元503还具体用于根据所述辅助窗口标记，确定所述所述辅助窗口，将不是辅助窗口的待渲染窗口作为主窗口。

存储器602可以包括只读存储器和随机存取存储器，并向渲染设备601直接或者间接的提供指令和数据。例如，在一种实现方式中，渲染设备601可以直接读取存储器602中的指令和数据从而实现其功能；在另一种实现方式中，渲染设备601中的部分指令或数据是通过其他处理器读取存储器602中的指令或数据并进行处理后发送给渲染设备用以指示其实现相应的功能。存储器602的一部分还可以包括非易失性随机存取存储器(NVRAM)。
此外，存储器602还存储了如下的元素，可执行模块或者数据结构，或者它们的子集，或者它们的扩展集:
