How to view the image in offchain data on second node

Sun, 02 Jun 2019 12:54:47 +0000

Hi All,

I have created a stream and saved an image as offchain data , when i check the 2nd node i can see the data as basecode 64( correct me if wrong -it is the format that store multichain stores the images) but when i try to convert the entire data to image in a web decoder I get no image . My question is how can I write an image in one node and view the same on another node, if i convert image to hash and store on stream then i wont be able to recover the image from the hash. please guide.

Thanks in advance

Large JSON image payload saves strange chars before and after hex

Hello,

i save an large JSON Payload with an png image in the MultiChain. Unfortunately the response hex is modified with some strange Charactes at the begin and at the end and between is the image. The example charactes are

"Ëð]tóGoL£îà_;Oºú~âFâ¥¹²ÆVjG0D LS[§Nl·.ÞkÀ4Ô'4=Öwm÷úØ¨5±¿¾µ &¼¯»×cÖ(Oô¼ìYºfð«|óÇÕ!á@É²¯ù¹âIýâ´AQzIÅiX=®jâÿÿÿÿ7v©@L]Úï gÀ¥! ¼Oì¢h£"¬spkq°aCý;[â< /²È±ûîuýÓNspkeIãâ~6`xª=ÞKö=äuspkk1527673616703ujM¦N"

an then the image is starting.

"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA+gAAAFACAYAAAAvc1ZOAAAgAElEQVR4Xu3dC7h271wn8O+QEoX0T2kmYqQDIUVRkZBI0UEq1RU6jYmmcphKVCZJ05Rihk7G0EkSQsohUpFMGR0mSQ6VFJ...."

the response hex from this transaction looks like this than:

Ëð]tóGoL£îà_;Oºú~âFâ¥¹²ÆVjG0D LS[§Nl·.ÞkÀ4Ô'4=Öwm÷úØ¨5±¿¾µ &¼¯»×cÖ(Oô¼ìYºfð«|óÇÕ!á@É²¯ù¹âIýâ´AQzIÅiX=®jâÿÿÿÿ7v©@L]Úï gÀ¥! ¼Oì¢h£"¬spkq°aCý;[â< /²È±ûîuýÓNspkeIãâ~6`xª=ÞKö=äuspkk1527673616703ujM¦Ndata:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA+gAAAFACAYAAAAvc1ZOAAAgAElEQVR4Xu3dC7h271wn8O+QEoX0T2kmYqQDIUVRkZBI0UEq1RU6jYmmcphKVCZJ05Rihk7G0EkSQsohUpFMGR0mSQ6VFJ....v©@L]Úï gÀ¥! ¼Oì¢h£"¬

BR,

UPDATE:

Was something completely different. These characters in every hex response. When the payload is to big multichain returns an object with a txid and vout. With the gettxoutdata you can get the larger response than.
