Render Electronic Signature objects for print
In order to format Electronic Signature objects for print in BO 4, you must first create a variable to replace the generic URL placeholder with the correct URL for your ETO environment, use another formula to isolate the image URL, then format the cell to display as Image URL. This differs from prior methods that just required the replacement of the generic URL placeholder and the cell to be displayed in HTML. This method still works to display the image in Edit mode but this image will no longer print.
Add a variable called "Signature"
In this variable, use this formula to replace the generic URL placeholder with the correct ETO software URL for your environment: =Replace([Electronic signature_26977*];"urlPlaceHolder";"https://secure.etosoftware.com") *replace with the electronic signature object from your report
In the cell in which you would like to display your Signature Image, add this formula to isolate the image URL: =Substr([Signature];Pos([Signature];"https");Pos([Signature];" alt")-Pos([Signature];"https")-1)
Select the Cell
On the Report Element Format panel, in the Appearance Settings, Select "Read content as:" Image URL
Adjust cell width and height to display the image.
An additional method is use the =Substr([Student Signature];Pos([Student Signature];"https");Pos([Student Signature];" alt")-Pos([Student Signature];"https")-1) formula as a pattern for the cells. And then set the display to be Stretched:
This will allow the signature to fill the cell entirely without having to create large cells to compensate for where the signature box was signed.
Reporting on Touchpoint Electronic Signatures
Your Electronic Signature Image should now be displayed correctly. This display will be maintained through a Print display and exported to PDF.
Users can report on TouchPoint Electronic Signatures within the flattened TouchPoint folders and through the standard TouchPoint universe.
In the example of a Results report based on the Standard TouchPoint universe below, Electronic Signature element is set up as an HTML cell with value coming from a ‘Signature Image’ variable. The formula in this variable replaces ‘urlPlaceHolder’ string with the actual ETOSoftware URL, which differs with the environment.
=Replace([Answer as Signature HTML];"urlPlaceHolder";"https://secure.etosoftware.com")
Be sure to set the Cell Display to "Hyperlink" in order to see the signature.
