示例1: getCanvas
ANPCanvas* PaintPlugin::getCanvas(ANPRectI* dirtyRect) {
ANPBitmap bitmap;
JNIEnv* env = NULL;
if (!m_surface || gVM->GetEnv((void**) &env, JNI_VERSION_1_4) != JNI_OK ||
!gSurfaceI.lock(env, m_surface, &bitmap, dirtyRect)) {
return NULL;
}
ANPCanvas* canvas = gCanvasI.newCanvas(&bitmap);
// clip the canvas to the dirty rect b/c the surface is only required to
// copy a minimum of the dirty rect and may copy more. The clipped canvas
// however will never write to pixels outside of the clipped area.
if (dirtyRect) {
ANPRectF clipR;
clipR.left = dirtyRect->left;
clipR.top = dirtyRect->top;
clipR.right = dirtyRect->right;
clipR.bottom = dirtyRect->bottom;
gCanvasI.clipRect(canvas, &clipR);
}
return canvas;
}示例2: drawPlugin
void AudioPlugin::drawPlugin(const ANPBitmap& bitmap, const ANPRectI& clip) {
ANPCanvas* canvas = gCanvasI.newCanvas(&bitmap);
ANPRectF clipR;
clipR.left = clip.left;
clipR.top = clip.top;
clipR.right = clip.right;
clipR.bottom = clip.bottom;
gCanvasI.clipRect(canvas, &clipR);
draw(canvas);
gCanvasI.deleteCanvas(canvas);
