Was this resolved? Or dead. I'd really like to use this. Would something like this "Decoding Base64 image in swift" from stack overflow help? https://stackoverflow.com/questions/51557553/decoding-base64-image-in-swift

Hello - thanks for your quick response! I implemented, to the best of my knowledge both compressed image and regular image message types - both needed for my situation. Given...

My images come from a ROS environment on a drone. I'm using the iPad as both a display and as a machine learning platform - the drone doesn't have enough...

No love. The string itself should be divisible by 4 apparently - and it isn't. Tossing in padding at the end "==" allows a valid base64 decode, but that doesn't...

The data sure seems to be ascii, i.e., not binary. The obvious thing is base64 decoding. That's hiccup #1 as it doesn't work. Also, this https://answers.ros.org/question/51490/sensor_msgscompressedimage-decompression/ seems to imply that...

started here... https://developer.apple.com/documentation/compression/compressing_and_decompressing_data_with_buffer_compression?language=objc though now that I think of it, it's doubtful this would be apple related. probably best to do a gzip decompression... that, or best yet look at...

okay, latest - the compression is handled by opencv imencode / imdecode. https://answers.opencv.org/question/188436/what-exactly-does-the-imencode-do-wanted-to-use-it-for-image-upload-onto-server/ Seems clear that the compressed format is binary. (Do ROS messages send anything in binary? Or is...

I'm having a heck of a time getting compressed image to work. I'm pretty sure from the documentation that opencv imencode/decode are the key functions to call. However, I'm having...

I'm most interesting in getting a compressed image on the ipad and publishing a small image (of floats) Testing this afternoon - code now compiles... swift rbsImageSubscriber = rbsManager?.addSubscriber(topic: "/subCompressed",...

Seems like this is a recent problem? See as well -- https://forums.developer.nvidia.com/t/run-dev-sh-failed-to-build-base-image-file-has-unexpected-size/277156/6
