@SYMTestCaseID GRAPHICS-EGL-0130
@SYMTestPriority 1
@SYMPREQ 39
@SYMREQ See SGL.GT0386.401 document
@SYMTestCaseDesc
When a RSgImage is used as both the source and target of a draw operation, then the operation should not panic.
However the outcome is undefined.
@SYMTestActions
Create and fully construct an RSgImage object
Pass the RSgImage objects 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 those calls to eglCreateImageKHR() do NOT return EGL_NO_IMAGE_KHR
Use vgCreateEGLImageTargetKHR() to construct a VGImage object from the just created EGLImage.
• Check for errors
Create Pixmap Surface from the previous RSgImage and make it current in a way that is compatible as a target for the VGImage to be drawn to.
• Set the iUsage bit to ESgUsageBitOpenVgSurface and ESgUsageBitOpenGlesSurface
Use OpenVG to draw a single patern to the left half of the VGImage created from the EGLImage.
Try to draw this VGImage to the right half of the pixmap surface currently linked to the context.
Call eglWaitClient() to finish the above drawing instructions synchronously.
Check that the pixmap contains expected pixel values.
Pass the VGImage into vgDestroyImage()
Pass the EGLImage into eglDestroyImageKHR()
Close the RSgImage
Destroy the pixmap
Check for memory and handle leaks
@SYMTestExpectedResults
This test is not supposed to panic.
The contents, though, are undefined since we are reading from and writing to the same memory
No memory or handle leaks.
