Describe the actual behavior

If an RGBA image is passed to solutions.drawing_utils.draw_landmarks (such as when using GPU mode, where the image must be RGBA), then solutions.drawing_utils.draw_landmarks fails. As a workaround, the image can be converted back to RGB prior to passing to this function.

Describe the expected behaviour

solutions.drawing_utils.draw_landmarks should work on RGBA images.

Hi @JC3,

Could you kindly provide the detailed steps you are following from our documentation, or alternatively, share the standalone code with us? This will help us to reproduce the issue and gain a better understanding of it.

Thank you!!

Can't repro; will investigate further and post back.

Hi @JC3,

Based on our team's investigation indicates that the existing MediaPipe visualization utilities API is not directly compatible with the new Tasks API. This is because the visualization utilities were designed for the legacy solutions.

For correct guidance on using visualization with the new Tasks API, please refer to the Colab example https://github.com/googlesamples/mediapipe/blob/main/examples/pose_landmarker/python/%5BMediaPipe_Python_Tasks%5D_Pose_Landmarker.ipynb.

Thank you!!
