This relates to #49. Basically a refactoring: It exposes image decompression as a stand-alone function in a separate lib. Additionally, it refactors the compressed subscriber to use that function. @dgossow...

[ROS 2] multiple publishers redeclare the same parameters

Strange issue that I only found with the CompressedPublisher, but it appears that its parameters are declared twice (or at least it does for me). Compiling ros2, image_transport and image_transport_plugins...

Between OpenCV 3 and 4, CV_LOAD_IMAGE_UNCHANGED changed to IMREAD_UNCHANGED. So to get this module to build with OpenCV 4, make this change in image_transport_plugins/compressed_depth_image_transport/src/codec.cpp, line 134: cv_ptr->image = cv::imdecode(imageData, IMREAD_UNCHANGED);...

Depth Quantization

2

Hello, Would somebody please explain what is the variable "depth_quantization" in [encodeCompressedDepthImage](https://github.com/ros-perception/image_transport_plugins/blob/indigo-devel/compressed_depth_image_transport/src/codec.cpp#L159) function? Also, what is the theory behind the formulas in lines 218, 219 and 233 of [codec.cpp](https://github.com/ros-perception/image_transport_plugins/blob/indigo-devel/compressed_depth_image_transport/src/codec.cpp)? Thank...
