How to call the Neon accelerated 2D Graphics Library in DVSDK 4.0

Hi,

I am very interested in the 2D Graphics Demo included in the DVSDK 4.0. So my question is : how to call the Neon accelerated 2D graphics library? Is there any example to show the usage of this 2D graphics library?  I just can't find any information or source code of the 2D graphics demo.

 

Thanks.

    Hello,

    Neon acceleration is plugged into the Qt library, you don't need seperate lib per say to use neon 2D acceleration.  Your typical application will call standard Qt API's and based on the operation it will use either neon accelerated path or use regular Qt path.

    BTW, the 2D demo you have seen in DVSDK 4.0  out-of-box is regular Qt application.

    Hope this helps.

    Thanks

    Hi Brijesh,

    Thanks for your reply.  But I believe the 2D graphics demo in DVSDK 4.0 is not a regular Qt application. After some Google search,

    I found the demo is a third party's application, i.e. blitrix bxdemo from http://www.drawelements.com/ .

    So, still my question is how can we call the library function? Do we developers need buy some license from DrawElements

     or TI already provided this library for developers to use?

    Thanks.

    The QPainter's drawImage function is just too slow even on Neon enabled ARM processor. We want to render 512*512 gray scale 8 bits image 30 frames per second, if the underlying library of  blitrix bxdemo can't be called by developers,  so what's the recommended way to do the real-time image rendering?

    Thanks.
