Ejemplo n.º 1

Archivo: LayerBase.cpp Proyecto: Android4SAM/platform_frameworks_native

void LayerBase::setPerFrameData(const sp<const DisplayDevice>& hw,
        HWComposer::HWCLayerInterface& layer) {
    // we have to set the visible region on every frame because
    // we currently free it during onLayerDisplayed(), which is called
    // after HWComposer::commit() -- every frame.
    const Transform& tr = hw->getTransform();
    layer.setVisibleRegionScreen(tr.transform(visibleRegion));
}

Ejemplo n.º 2

Archivo: Layer.cpp Proyecto: trebon-chocodot/android_frameworks_native

void Layer::setPerFrameData(const sp<const DisplayDevice>& hw,
        HWComposer::HWCLayerInterface& layer) {
    // we have to set the visible region on every frame because
    // we currently free it during onLayerDisplayed(), which is called
    // after HWComposer::commit() -- every frame.
    // Apply this display's projection's viewport to the visible region
    // before giving it to the HWC HAL.
    const Transform& tr = hw->getTransform();
    Region visible = tr.transform(visibleRegion.intersect(hw->getViewport()));
    layer.setVisibleRegionScreen(visible);

    // NOTE: buffer can be NULL if the client never drew into this
    // layer yet, or if we ran out of memory
    layer.setBuffer(mActiveBuffer);
