Example 6 with YuvImage

use of android.graphics.YuvImage in project zxing-android-embedded by journeyapps.

the class SourceData method getBitmap.

private Bitmap getBitmap(Rect cropRect, int scaleFactor) {
    if (isRotated()) {

    // TODO: there should be a way to do this without JPEG compression / decompression cycle.
    YuvImage img = new YuvImage(data, imageFormat, dataWidth, dataHeight, null);
    ByteArrayOutputStream buffer = new ByteArrayOutputStream();
    img.compressToJpeg(cropRect, 90, buffer);
