@SYMTestCaseID GRAPHICS-EGL-0107

@SYMTestPriority 1

@SYMPREQ 39

@SYMREQ See SGL.GT0386.401 document

@SYMTestCaseDesc

Tests the use of an EglImageKHR object with OpenVG, using the “EGL_IMAGE_PRESERVED” attribute.

This means we can draw to the source RSgImage as soon as it is created.

@SYMTestActions

This test will check for the “VG_KHR_EGL_image” extension, if it is not supported on this platform then the test will return immediately without failure.

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

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 the “EGL_IMAGE_PRESERVED” attribute

Check that eglCreateImageKHR() does NOT return EGL_NO_IMAGE_KHR

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

•	Set the iUsage bit of the underlying RSgImage to ESgUsageBitOpenVgSurface 

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

•	Check for errors

Use OpenVG to copy  the VGImage created from the EGLImage to the new pixmap 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 pixmap contains expected pixel values.

Destroy the pixmap

Check for memory and handle leaks

@SYMTestExpectedResults

eglCreateImageKHR() does NOT return EGL_NO_IMAGE_KHR

After each call to an OpenVG method, check that vgGetError() returns VG_NO_ERROR

The pixmap contains expected pixel values after the original image data has been destroyed

No memory or handle leaks
