John	Posted - Oct 23 2013 : 21:20:36 Hello I am utilizing the JSignature JavaScript component which allows writing a signature on the component in a browser and then exporting the signature data using a vector data compression algorithm to a memo field in a database record. The compression algorithm I am using is base30, although the component also has SVG and a native compression algorithm. I can copy this saved data back to a JSignature component from a database memo field via the following code: var tempData: String; tempData := kbmMemTable1.FieldByName('Signature').AsString; IWCGJQSignature.JQSignatureOptions.SetData(tempData); Does the ImageEnVect component have a method to take vector data that has been compress via base30 and placed into a DB memo field and reverse the process, i.e. decompress the data and load it into a ImageEnVect canvas? TIA John
