Converts a ROS image message to a QImage.

Converts ROS image messages of different encodings to QImage. This function calls cv_bridge::toCvCopy to convert the image to a cv image first. If the cv image is not of type rgb8, it converts the image to an rgb format using cv_bridge::CvtColorForDisplay with options . The cv image is then converted to a QImage.

Parameters:

  • msg – The ROS image message to convert.

  • options – The options to use when converting a single-channeled image (eg. depth images)

Returns:

QImage The QImage representation of the ROS image message.
