PDF Callout Annotation Tool, Text Annotation Custom Fonts, Sepia Mode, and More in PDFTron SDK for iOS 7.1.2

We are pleased to announce version 7.1.2 of PDFTron's iOS SDK.

In this release we've added a new callout annotation tool, support for custom fonts in text annotations and reflow mode, a new sepia viewing mode, an improved document sharing UI, and more.

This release adds the ability to create and edit callout annotations for users to add text notes with an arrow pointing to specific points of interest on the document. For example, your users might want to add a comment to a blueprint, pointing out where a building's construction went wrong. Or they may want to point out a part of a sentence that's misspelled, suggesting an alternative.

With this release it's now possible to use custom fonts for [PTFreeText](https://www.pdftron.com/api/ios/Classes/PTFreeText.html) annotations so you can further personalize your app to suit your needs.

We are also pleased to introduce custom font support for the powerful and convenient reflow mode. This will allow you to customize the PDF reading experience even more, and gives your users the ability to personalize their viewer.

Reflow (or Reader mode) displays the content of a PDF in more-readable format, similar to how Reader mode in Safari works for websites. The style, default font, and formatting of the original text is maintained, and any text annotations such as highlights or underlines are also shown. With images now also shown in Reflow mode, the user experience is even better!

There is a new sepia mode available which can be toggled using the PTDocumentViewSettingsController. Many people find sepia mode easier on the eyes which makes for a better reading experience and we're pleased to introduce this feature for both reflow and non-reflow mode.

The PTDocumentViewController'sshareButtonItem now presents a UIActivityViewController. This makes it easy to disable any of the builtin share actions (print, copy to clipboard, email, etc.), add custom actions, and have more control over the sharing process (preparing document for sharing by flattening, optimizing, etc.).

Please see our change log for a list of all changes in this release.
