How to force signature to respect signHere tab's bounding box ?

Hello @Joachim 

Thanks for contacting DocuSign support.

Please review this:

*Refine Coordinate Adjustment:

Double-check your page size calculation for the y-coordinate conversion. There might be a small offset you need to account for beyond just the page height.

Experiment with adding/subtracting a few pixels to the y-coordinate to see if it corrects the vertical shift.

*Use Anchor Tags (Alternative):

Consider using Anchor Tags instead of absolute positioning. These link SignHere tabs to specific text strings in your PDF. This eliminates the need for precise coordinate calculations and adapts better to potential rendering variations.

*Scale Signatures (Temporary Fix):

While not ideal, setting a ScaleValue of 0.5 on the SignHere tab can temporarily reduce signature size. However, it won't enforce a strict bounding box.

*Explore Custom Fields (Advanced):

If you have more control over your PDF generation, consider adding hidden text fields (white on white) at the desired signature locations. Link your SignHere tabs to these fields for precise control.

Note: This approach requires advanced PDF manipulation skills.

Additional Tips:

I would like avoid alternatives like relative anchoring, because this will not solve my main issue. Anchoring will not solve the signature size issue and an offset may remain


Signatures are too big, and scale factor is not convenient. Ideal would be a bounding box.

Once the signature is scaled, an offset remain. Without fixing offset, the sign-here arrow in a box is well-placed (it fits into cell) but the signature itself is too low. With fixing offset of one half-height, the sign-here box is one half-cell height to high, but the arrow is pointing to the middle of the cell and the signature is more centered.

The coordinates refinement shouldn’t be necessary and signature should have boundaries.

Docusign reversed Y coordinate is another issue. Why not sticking to PDF natural coordinate system ? Relative anchoring is easier for HTML documents, so they are not a priority when considering where to put absolute coordinates origin.

Hello,

Is there a real answer to this problem ?

I also need my signatures to fit in a given box.
