# This message contains a compressed image. std_msgs/Header header # Header timestamp should be acquisition time of image # Header frame_id should be optical frame of camera # origin of frame should be optical center of cameara # +x should point to the right in the image # +y should point down in the image # +z should point into to plane of the image string format # Specifies the format of the data # Acceptable values differ by the image transport used: # - compressed_image_transport: # ORIG_PIXFMT; CODEC compressed [COMPRESSED_PIXFMT] # where: # - ORIG_PIXFMT is pixel format of the raw image, i.e. # the content of sensor_msgs/Image/encoding with # values from include/sensor_msgs/image_encodings.h # - CODEC is one of [jpeg, png, tiff] # - COMPRESSED_PIXFMT is only appended for color images # and is the pixel format used by the compression # algorithm. Valid values for jpeg encoding are: # [bgr8, rgb8]. Valid values for png encoding are: # [bgr8, rgb8, bgr16, rgb16]. # If the field is empty or does not correspond to the # above pattern, the image is treated as bgr8 or mono8 # jpeg image (depending on the number of channels). # - compressed_depth_image_transport: # ORIG_PIXFMT; compressedDepth CODEC # where: # - ORIG_PIXFMT is pixel format of the raw image, i.e. # the content of sensor_msgs/Image/encoding with # values from include/sensor_msgs/image_encodings.h # It is usually one of [16UC1, 32FC1]. # - CODEC is one of [png, rvl] # If the field is empty or does not correspond to the # above pattern, the image is treated as png image. # - Other image transports can store whatever values they # need for successful decoding of the image.
