In My case, I use ImageView in the layout file on the filter apply so to capture a Bitmap set bitmap into Image View.

When changing Image Change Gpuimage & ImageView at the same time

GPUImage filterLoader;
ImageView view_filter;

// Inslize the View
view_filter = findViewById(R.id.view_filter); // Form your layout file
filterLoader = new GPUImage(this); // Just only in java code Not a child for any layout or View

//When filter apply change the Image
filterLoader.setFilter(new GPUImageGlassSphereFilter()); // Set Filter

setImage(filterLoader.getBitmapWithFilterApplied()); // Capture bitmap

// Fill the Bitmap
private void setImage(Bitmap fill) {
view_filter.setImageBitmap(fill);
filterLoader.setImage(fill);
}
