Convert depth image to pointclouds

[Profsarku]

Hi,
I have a 16bit depth image I want to convert to point clouds using the code below but I get the error:
RuntimeError: [Open3D Error] (class std::shared_ptr __cdecl open3d::geometry::PointCloud::CreateFromDepthImage(const class open3d::geometry::Image &,const class open3d::camera::PinholeCameraIntrinsic &,const class Eigen::Matrix<double,4,4,0,4,4> &,double,double,int,bool)) D:\a\Open3D\Open3D\cpp\open3d\geometry\PointCloudFactory.cpp:171: [CreatePointCloudFromDepthImage] Unsupported image format.

`import open3d as o3d
import matplotlib.pyplot as plt
import numpy as np

o3d.t.geometry.PointCloud

raw_depth = o3d.t.io.read_image('outdoor1.png')
pcd = o3d.t.geometry.PointCloud.create_from_depth_image(raw_depth,
o3d.camera.PinholeCameraIntrinsic(
o3d.camera.PinholeCameraIntrinsicParameters.PrimeSenseDefault))
pcd.transform([[1, 0, 0, 0], [0, -1, 0, 0], [0, 0, -1, 0], [0, 0, 0, 1]])
print(np.asarray(pcd.points)[1,:])
o3d.visualization.draw_geometries([pcd])`

the depth image is below:

Any help will be really appreciated!!
