Urgent Support Required : Unable to get the image dimension in the edit view

Hi All,

i created a field where user can do their signature with the help of signature canvas .

I stored the signature image dimension in the database from the edit view

the image dimensions are like -:

{β€œlx”:187,β€œly”:94,β€œmx”:186,β€œmy”:94},{β€œlx”:194,β€œly”:94,β€œmx”:187,β€œmy”:94},{β€œlx”:207,β€œly”:99,β€œmx”:194,β€œmy”:94},{β€œlx”:207,β€œly”:100,β€œmx”:207,β€œmy”:99},{β€œlx”:207,β€œly”:103,β€œmx”:207,β€œmy”:100},{β€œlx”:198,β€œly”:108,β€œmx”:207,β€œmy”:103},{β€œlx”:180,β€œly”:113,β€œmx”:198,β€œmy”:108},{β€œlx”:155,β€œly”:113,β€œmx”:180,β€œmy”:113},{β€œlx”:122,β€œly”:98,β€œmx”:155,β€œmy”:113},{β€œlx”:117,β€œly”:87,β€œmx”:122,β€œmy”:98},{β€œlx”:117,β€œly”:82,β€œmx”:117,β€œmy”:87},{β€œlx”:117,β€œly”:81,β€œmx”:117,β€œmy”:82},{β€œlx”:127,β€œly”:80,β€œmx”:117,β€œmy”:81},{β€œlx”:134,β€œly”:84,β€œmx”:127,β€œmy”:80},{β€œlx”:142,β€œly”:93,β€œmx”:134,β€œmy”:84},{β€œlx”:146,β€œly”:102,β€œmx”:142,β€œmy”:93},{β€œlx”:147,β€œly”:102,β€œmx”:146,β€œmy”:102}

,The signature is getting displayed in the detail view ,which meant the imaged dimension is getting stored in the database.,

but on trying to update the same record, i am unable to get the image dimensions from the database.and hence signature is not visible .
Every other field is getting populated from the database but the signature image dimension stored in database due to which i am unable to view the signature and on saving it the signature is getting lost .

Can anyone help me with this…??? ITS URGENT…
