@SYMPREQ 39

@SYMREQ See SGL.GT0386.401 document

@SYMTestCaseDesc

Check that it is possible to draw a VGImage (created from an RSgImage) to a pBuffer Surface.

@SYMTestActions

Create a reference Bitmap

Create and fully construct an RSgImage object having the same content as the reference bitmap 

•	Set the iUsage bit to ESgUsageBitOpenVgImage

Create and make current and EGL context bound to OVG APIs and linked to a pBuffer surface.

Pass the RSgImage object into eglCreateImageKHR() with

•	The target parameter set to EGL_NATIVE_PIXMAP_KHR

•	Use the current display and EGL_NO_CONTEXT

•	Use a NULL attr_list

Check that eglCreateImageKHR() does NOT return EGL_NO_IMAGE_KHR

Use vgCreateEGLImageTargetKHR() to construct a VGImage object from the EGLImage.

•	Check for errors

Use OpenVG to draw the just created VGImage to the pBuffer surface currently linked to the context.

Call eglWaitClient() to finish the above drawing instructions synchronously.

Destroy the original image data

•	Pass the VGImage into vgDestroyImage()

•	Pass the EGLImage into eglDestroyImageKHR()

•	Close the RSgImage 

Check that the pBuffer surface matches the content from the reference bitmap.

Destroy the pBuffer surface

Check for memory and handle leaks

@SYMTestExpectedResults

pBuffer surface matches the content from the reference bitmap.

The test will loop through all the possible PixelFormat available for source RSgImages and Destination Surfaces

•	EUidPixelFormatRGB_565

•	EUidPixelFormatXRGB_8888

•	EUidPixelFormatARGB_8888 (source only)
