Vivante 2D API Create Surface from Existing Data

adamk — Wed, 15 Jun 2016 18:43:33 GMT

Hello,

Is it possible to create a surface from existing data using the Vivante 2D API ?

Rather than following this procedure, which works:

　　/* Create a surface that will hold a source 2D image. */

　　gcoSURF_Construct(hal, width, height, depth, type, format, pool,

　　　　surface);

　　：

　　　　/* Lock the surface's memory so that it can be accessed. */

　　　　gcoSURF_Lock(*surface, NULL, surfaceMemory);

Then writing out the data.

I would like to construct a surface from existing data.

Hi Adam,

It should be possible, please take a look to the following communilinks:

I am afraid I do not understand because the linked thread is referring to OpenGL. Can you explain more clearly the connection between virtual framebuffers and 2D API? Once obtained the data in a virtual framebuffer, how can I construct a surface?

Any clarification on the 2D API-virtual framebuffer integration?
