Description:
|
||
|
|
|
||
|
|
Checks for EGL surface behavior when the surface's native window is resized by external means.
|
||
|
|
|
||
|
|
The surface_size.* tests resize the native window and call
|
||
|
|
eglSwapBuffers(). Then EGL_WIDTH and EGL_HEIGHT are checked to verify
|
||
|
|
that they report the new native window size.
|
||
|
|
|
||
|
|
The back_buffer.* tests create an EGL_BUFFER_PRESERVED surface and draw
|
||
|
|
a test image on it. The native window is resized, and the back buffer is
|
||
|
|
checked to see that it is similar to the original test image in some
|
||
|
|
corner.
|
||
|
|
|
||
|
|
The pixel_density.* tests query the EGL_HORIZONTAL_RESOLUTION and
|
||
|
|
EGL_VERTICAL_RESOLUTION attributes of the surface both before and after
|
||
|
|
resizing. These are compared to the size of the native image in physical
|
||
|
|
display pixels. An error is reported if the results are inconsistent,
|
||
|
|
i.e. if they imply that the size of a physical display pixel changed
|
||
|
|
size during resizing.
