New in 3.4.0 • Copy and paste annotations between open documents. • Drop PDFs between page thumbnails to insert pages exactly where you want them. • Save placed stamps back to your stamp collection and see selected annotation colours in the toolbar. • Text selection and substituted-font rendering now align more precisely. • Faster tab grids, smoother trackpad zooming, safer progressive file access, and more reliable print previews.

New in 3.3.0 • Pages you revisit open instantly, with optional background warming and persistent full-resolution caching. • Sharper deep zoom on scanned and image-based PDFs. • Better touch panning, rectangle corner-radius controls, and smoother inserted-page navigation.

New in 3.2.0 • Faster, steadier viewing with memory-aware page caching and less duplicate rendering. • Better FreeText and callout compatibility, plus more precise selection of multi-line markups. • Fixes loading pauses, remote-session restore delays, and Ctrl/Cmd-wheel zoom after constrained drawing.

New in 3.1.0 SCAN AND CAPTURE • Scan paper documents straight into a PDF — start a new document from a scan or insert pages into the open file. • Take a photo with the camera and add it to your document. PEACE OF MIND • Unsaved changes are mirrored in the background and restored after a crash, so your work survives. NEW TOOLS • Add hyperlinks to the web or to another page in the document. • Crop placed images and pasted pictures. • Lock annotations against accidental edits, and unlock them when needed. • Every editing tool now has a keyboard shortcut. • Search now finds text inside your notes and annotations, too.

New in 3.0.0 LANGUAGES • DartPDF is now available in 10 languages, with full right-to-left layout for Arabic.

EDITING • Hold Shift while drawing to constrain ink and lines to straight strokes. • Set a default style for annotations and reuse it with one tap. • Redesigned document tabs that stay readable as you open more files. SPEED • Faster rendering and lower memory use, with the biggest gains on large or image-heavy files. Thank you for using DartPDF. Feedback and bug reports are always welcome.

New in 2.1.0 READING • Reflow reading view: read a document as flowing text instead of fixed pages, with lazy scrolling through long files, quick navigation, a reading position that is remembered, and a figure viewer for tapping through images and diagrams. SPEED AND MEMORY • Documents open and render noticeably faster, with the biggest gains on large or image-heavy files. • Saving an edit is now proportional to the size of the change rather than the size of the document, so edits stay fast in long files. • Lower memory use on very wide drawings, which now keep only the visible portion of the page in memory as you pan. • Faster decoding of scanned black-and-white documents. RENDERING FIXES • Fine linework stays crisp and legible when zoomed out, instead of fading away — a difference you will notice most on drawings and plans. • More accurate colour in gradients, including radial gradients that previously showed only a partial shape. • Correct colour for indexed images, including those built on JPEG 2000, Separation and DeviceN bases. • Symbol and ZapfDingbats characters now render properly instead of appearing as empty boxes. • Sampled colour functions with multiple inputs are evaluated correctly.
