PDF Scanner: Scan Sign OCR

A big update to editing, and a fix to how scans handle shadows. SHADOWS Grayscale and B&W Text now flatten the page's lighting before they convert. Photograph a document with a shadow across it and that area no longer comes back filled in solid black — which is what a plain black-and-white threshold does to anything that falls below its cut-off. MARKUP • Undo, Redo and Reset, on the toolbar where you can see them. • The eraser asks before it clears a page, and tells you whether marks you have already applied are among the ones going. • A new tool palette that you can drag anywhere and park against any edge, collapse into a small button, and see through while you work. • A straight-edge with turn-left and turn-right buttons, so you can set a precise angle instead of wrestling a two-finger gesture. It snaps to 45° steps, and everything you draw follows it. • Pen, highlighter, pencil and two erasers — rub out part of a mark, or remove a whole one in a tap. SIGNING • The Sign tab is one screen now: your document on top, your saved signatures underneath, with "Create New" first. • Undo, Redo and Reset while you sign, on the same row as the page controls. • Pen styles and widths when you draw a signature — pen, marker, pencil, monoline and fountain pen. • Place a signature with one finger, resize it with two, and see it on the page the moment you apply it. • Tap a signature you have already placed to select and remove it — which keeps working after the document has been saved and reopened. ENHANCE • Crop and rotate are now the first row, above the filters, with their names on them. They used to be three unlabelled icons below everything else. • Undo and Redo, next to a larger Apply button. • Sharp Text, for pages whose print is simply too faint. It removes the page's uneven lighting first and only then darkens, so the text gets darker without the shadows getting stronger. • Preview any filter before you buy — the Pro check now happens when you apply, not when you look. • "Recognize text" while enhancing, to give a text layer to a page that never had one. REVERT TO ORIGINAL Markup and Sign now offer it too, on the page you are looking at, next to the controls you are already using. It was only in Enhance and in the page manager before. PAGES Crop and rotate are now buttons on each page row, instead of being hidden in a menu. FIXES • The checkmark at the top right no longer throws away a signature you have placed but not yet applied. It now does what it looks like it does. • Signatures and markup are saved the same way up you drew them. • Warnings before a destructive step are centred on screen instead of pointing at the wrong part of it, and they are about 70% shorter — they now name only what you cannot get back. • Reverting an enhanced page to how it looked before is available to Pro subscribers. Copies are kept for everyone, from the first time you enhance a page, so the option is there for anything you have already scanned. • Enhancing a page that has no readable text no longer rebuilds it for nothing. • "Make Searchable" no longer redraws your document when there is no text to find. It tells you nothing could be read and leaves the file exactly as it was, instead of replacing it with a lower-quality copy of itself. • Tapping the checkmark immediately after drawing no longer loses the mark. A stroke takes a moment to be handed over after you lift your finger, and a fast tap could arrive first. • Warnings before clearing marks are centred on screen on iPad instead of pointing at the wrong part of it. • Marks on a sideways or upside-down page are saved where you put them. On a PDF that arrives already rotated, a signature could vanish from the saved file and markup could shift across the page.
