In android, I get an Image object from here https://inducesmile.com/android/android-camera2-api-example-tutorial/ this camera tutorial. But I want to now loop through the pixel values, does anyone know how I can do that? Do I need to convert it to something else and how can I do that?
Thanks

Converting a vector graphic or object to a bitmap lets you apply special effects to the object with CorelDRAW. The process of converting a vector graphic to a bitmap is also known as “rasterizing.” When you convert the vector graphic, you can select the color mode of the bitmap.
A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different color. In this instance we will simply create a Bitmap directly: Bitmap b = Bitmap.
ImageFormat#YUV_420_888 is one of the most common image format supported by Android Cameras. It's a multi-plane YUV (YCbCr) format represented by three separate planes in android. media. Image and the order of the planes is guaranteed to be: [0]: Y plane (Luma)
Bitmap image type is also a image extension mostly used in android applications to create and store drawable images inside android projects.
Get local drawable resource imageview image and convert into bitmap type dynamically using coding on button click. Bitmap image type is also a image extension mostly used in android applications to create and store drawable images inside android projects.
bitmap = BitmapFactory.decodeResource (getResources (), R.drawable.image); 1-Store the path to the image file as a string variable. To decode the content of an image file, you need the file path stored within your code as a string.
1-Store the path to the image file as a string variable. To decode the content of an image file, you need the file path stored within your code as a string. Use the following syntax as a guide: Bitmap picBitmap; Bitmap picBitmap = BitmapFactory.decodeFile (picPath);
If you want to loop all throughout the pixel then you need to convert it first to Bitmap object. Now since what I see in the source code that it returns an Image, you can directly convert the bytes to bitmap.
Image image = reader.acquireLatestImage(); ByteBuffer buffer = image.getPlanes()[0].getBuffer(); byte[] bytes = new byte[buffer.capacity()]; buffer.get(bytes); Bitmap bitmapImage = BitmapFactory.decodeByteArray(bytes, 0, bytes.length, null); Then once you get the bitmap object, you can now iterate through all of the pixels.
