| 6 | * This test calculates the roundtrip speed of copy offscreen buffer to window
|
|---|
| 7 | * operations. Besides the time necessary for copying pixels, this also includes
|
|---|
| 8 | * the time necessary to fill 2D rectangles in the offscreen buffer, deliver
|
|---|
| 9 | * paint and timer messages and so on.
|

| 10 | *
|

| 11 | * To also get the speed of only the copy operatoins themselves, add

| 12 | *
|

| 13 | * #define QT_LOG_BLITSPEED

|

| 15 | * to the beginning of qapplication_pm.cpp and qwindowsurface_raster.cpp.

| 17 | * Hint: in order to get the most realistic numbers, let the test run until the
|
|---|
| 18 | * average speed printed in the window title stabilizes (i.e. stops to grow).
