Today we are excited to introduce new APIs to the PDFTron SDK for Android for creating stamps with custom appearances, creating measurement annotations, creating callout annotations, and more.

linkCustom rubber stamps

In addition to creating pre-defined stamps in RubberStampCreate tool introduced in v6.8.5, today we have expanded its functionality with the ability to create custom appearances.

It's now easy to create and save custom rubber stamps to Android apps for any appearance you might want. Here's a preview:

linkMeasurement tool

Looking to measure distance on documents? Similar to the WebViewer sample, this is now also supported on Android through the new RulerCreate tool. It supports three different units of measurement (cm, inches, yards), for fast measurement of any distance on any document. Measurement tools are often used in the construction space, especially for estimating materials. For example, you might want to measure the length of a wall in a blueprint, to estimate the amount of material needed to build that wall. As a result, measurement tools are a vital part of keeping construction projects within budget.

Here's a preview:

linkCallout tool

Lastly, the latest tool in the collection is CalloutCreate which creates callout annotations that can be used whenever you'd like to comment on a specific part of a PDF page, and have your comment appear on the page itself (instead of in a separate comment displayed outside the page). For example, you might want to add a comment to a blueprint, pointing out where a building's construction went wrong. Or you might want to point out a part of a sentence that's misspelled, suggesting an alternative.
