How to convert image from Base64 to 256-color BMP format in ABAP

Hi All,

1. Signature is coming in BASE 64 format from mobile app and it is connected with ODATA SAP ON-PRIMESES database.

2. Signature is stored in Al11 directories.

3. While calling smartform signature is fetched from AL11 then storing in through BDS (SE78) and displaying on smartforms.

4. However background of signature displayed on smartform is Gray signature-in-smartforms.jpg.

5. Program code is attached.signature-code.txt

6. Requirement is to have signature with white background on the smartform.
