Everything the editor put on a page was final. A text stamp could not be corrected without deleting it and typing it again, nothing could be resized, and the only way to remove a mark was a Delete key nobody had been told about — the selection drew a dashed box and offered no action at all. Placing a stamp also left its tool armed, so the next click stamped a second copy. Marks are now editable objects. Selecting one gives it grab handles and a small bar pinned above it: delete and duplicate for anything, and for text an edit button, a size stepper and bold and italic. Double-clicking text reopens it for rewriting in place rather than adding a second one. Placing a text stamp or a signature drops straight back to the select tool with the new mark live, which is both what people expect and what puts it immediately within reach of a nudge. Resizing is one function over every mark type rather than a special case per kind: a handle drag produces a new bounding box, and the mark is mapped from its old box into that one. Text scales by font size instead of stretching its glyphs, signatures keep their aspect on a corner, and lines offer their two endpoints instead of a box that would let you stretch them in ways you never aimed at. A whole gesture lands on the undo stack as one step. Selecting a thin mark used to mean clicking its outline exactly — about one screen pixel. Each stroked mark now carries an invisible fat copy of itself purely to catch the pointer. New marks to go with it: underline and strike-through, which share the highlight's text-selection geometry and differ only in where the rule sits; a plain line; and a fill toggle for rectangles and ellipses. Bold and italic mean three more Helvetica variants embedded at save time, since a PDF treats them as separate fonts rather than as a style. Double-click is detected from the pointer stream rather than from a dblclick listener, because selecting a mark calls preventDefault() on the pointerdown and that suppresses the compatibility mouse events the browser would have synthesised the dblclick from.

<h2>About redaction</h2>
|
||
<p>A redaction box hides content visually. On its own it does <strong>not</strong> remove the
|
||
text underneath, which stays extractable by anyone who copies from the file.</p>
|
||
<p>To actually remove it, this editor rebuilds each redacted page as an image when you save.
|
||
That page's text stops being selectable and any form fields on it become static. Pages you
|
||
did not redact are untouched.</p>
