Revision history [back]

For a compressed image, the byte stream in the data array is the jpeg compressed representation of the image. To use it with OpenCV, this jpeg representation first has to be decompressed to a uncompressed representation. Luckily, this is made transparent by the image_transport mechanism, so this is taken care of for you if you use that. Have a look at compressed_image_transport.
