SAP iRPA queries

Hello exerts,

I have below queries related to iRPA, I am clubbing all of them together instead of creating seperate questions. (all related to Cloud studio)

• How can i read characters from the image? Is there any library to do it?
• How can i read barcode data in case there is such specific requirement? Any external library?
• When I capture any SAP UI5 screen and then I want to remove it from all the capture screen. I do not see any option to "delete the screen". Is there any other way to do that?
• I do not have agent installed at the remote server so, I capture remote screen using "Surface Automation". Now how can i execute it later? Do i have to always keep remote desktop screen active?
• When I use Document Information Extraction SDK and define PDF element and activate it. Later, If I want to EDIT it again, I am not able to find any option to do that.

Any help would be appreciated.

Reagards,
