Summary: Add option to PDVisibleSignDesigner to use page user
space coordinates for the signature rectangle
Key: PDFBOX-6307
URL: https://issues.apache.org/jira/browse/PDFBOX-6307
Project: PDFBox
Issue Type: Improvement
Components: Signing
Affects Versions: 2.0.37, 2.0.36, 2.0.38
Reporter: Evandro Magalhaes Leite Junior
{\{PDVisibleSigBuilder.createSignatureRectangle()}} always converts the y
position with the template height (the lower left y is {{templateHeight
- yAxis - height}}). This assumes that \{{yAxis}} is measured from the top of
the template.
Callers that already have coordinates in the default user space of the page
(origin at the lower left of the unrotated page) cannot place the
visible signature exactly where they want without compensating for this
conversion. This is especially awkward for pages with a \{{/Rotate}}
entry.
Proposal: add an opt-in option
\{{PDVisibleSignDesigner.useUserSpaceCoordinates(boolean)}} (getter
\{{isUseUserSpaceCoordinates()}}), default
\{{false}}. When enabled, \{{xAxis}} and \{{yAxis}} are used as the lower
left corner of the rectangle, and the upper right corner is {{xAxis +
width}}, \{{yAxis + height}}. The page rotation is not taken into account.
The default behaviour is unchanged.
The behaviour is documented in the javadoc of
\{{PDFTemplateBuilder.createSignatureRectangle()}} and of the new methods. A
unit test
(\{{PDVisibleSignDesignerTest}}) covers both modes.
