Holoscan v0.5.1
void holoscan::viz::ReadFramebuffer(ImageFormat fmt, uint32_t width, uint32_t height, size_t buffer_size, CUdeviceptr device_ptr)

Read the framebuffer and store it to cuda device memory.

Can only be called outside of Begin()/End().

  • fmt – image format, currently only R8G8B8A8_UNORM is supported

  • width, height – width and height of the region to read back, will be limited to the framebuffer size if the framebuffer is smaller than that

  • buffer_size – size of the storage buffer in bytes

  • device_ptr – pointer to Cuda device memory to store the framebuffer into
