| Title |
| |
| Tests: |
| + dEQP-EGL.functional.resize.* |
| |
| Includes: |
| + EGL_WIDTH and EGL_HEIGHT |
| + Preservation of back buffer contents |
| + EGL_*_RESOLUTION consistency |
| |
| Excludes: |
| + Preservation of front buffer contents |
| |
| 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. |
