Digital signatures in exported PDFs • Reworked how digital signatures are embedded in exported PDFs for broader compatibility with PDF readers and signature validators. • The signature mark is now drawn as a real PDF appearance stream, so it stays crisp at any zoom instead of being flattened into the page image. • A signature placed off the page is refused with a clear message instead of producing a file that readers cannot open. Annotations and export • Signature blocks have eight resize handles and a minimum size in page points, and they lay out identically on screen and in the exported PDF. • Signature images render at full export resolution on every platform. • Callout borders can be cleared, and callout decoration now scales with the page like every other annotation. • PDFs with rotated pages import correctly. Fixes • Escape closes the Coverage Areas popover. • Return confirms the visual-search placement sheet. • The app recovers if it is launched without a window. • Added third-party license attribution to the user guide, and a privacy manifest declaring the required-reason APIs the app uses.
