Hi, I'm writing a node to publish images from the Surveyor stereo camera (see http://www.surveyor.com/stereo/ ). The camera publishes the images in JPEG format. The logical thing would be to somehow feed them to the compressed_image_format node (after setting up a handmade header?) to publish them. Is there any example code which does this? Also, if I understand correctly, the subscriber can just subscribe to the normal image_transport topic, but needs to have extra code to decompress compressed images before using them?
