示例1: drawBitmap

static void drawBitmap(JNIEnv* env, jobject jcanvas, jlong canvasHandle, jlong bitmapHandle,
                       jfloat left, jfloat top, jlong paintHandle, jint canvasDensity,
                       jint screenDensity, jint bitmapDensity) {
    Canvas* canvas = get_canvas(canvasHandle);
    const SkBitmap* bitmap = reinterpret_cast<SkBitmap*>(bitmapHandle);
    const Paint* paint = reinterpret_cast<Paint*>(paintHandle);

    if (canvasDensity == bitmapDensity || canvasDensity == 0 || bitmapDensity == 0) {
        if (screenDensity != 0 && screenDensity != bitmapDensity) {
            Paint filteredPaint;
            if (paint) {
                filteredPaint = *paint;
            }
            filteredPaint.setFilterLevel(Paint::kLow_FilterLevel);
            canvas->drawBitmap(*bitmap, left, top, &filteredPaint);
        } else {
            canvas->drawBitmap(*bitmap, left, top, paint);
        }
    } else {
        canvas->save(SkCanvas::kMatrixClip_SaveFlag);
        SkScalar scale = canvasDensity / (float)bitmapDensity;
        canvas->translate(left, top);
        canvas->scale(scale, scale);

        Paint filteredPaint;
        if (paint) {
            filteredPaint = *paint;
        }
        filteredPaint.setFilterLevel(Paint::kLow_FilterLevel);

        canvas->drawBitmap(*bitmap, 0, 0, &filteredPaint);
        canvas->restore();
    }
