The rendering pipeline now uses SIMD processing and multithreaded execution to speed up image loading and rendering (only available in ARM-v7 and x86 libraries). * Tools source code is now included as part of the standard distribution as an Android library. The PDFViewCtrlDemo sample project should now reference the PDFViewCtrlTools project on the same workspace. The code can also be used as a template to build new tools. * \[Tools] Added new DigitalSignature tool, a new sample annotation tool showing how to apply a digital signature to a signature field. It allows the user to draw his/her own signature or choose an image file as the appearance. Please note that this tool is for demonstration purposes and uses a pre-generated dummy certificate for signing. * \[Tools] Added new RichMedia tool, which can play embedded rich media content (supported media formats are dependent on the device's Android version). * New PDFViewCtrl APIs. Please see documentation for details: * Tool.onScrollChanged * Tool.onConfigurationChanged * getOCGContext * setOCGContext * setTextSearchListener * HTTPRequestOptions * LinkInfo.getRect * getDeviceTransform * getPageCount * getVisiblePages * setPageTransparencyGrid * Changed PDFViewCtrl APIs: * PDFViewCtrl.openURL * convClientPtToCanvasPt replaced by convScreenPtToCanvasPt * convClientPtToPagePt replaced by convScreenPtToPagePt * convCanvasPtToClientPt replaced by convCanvasPtToScreenPt * convPagePtToClientPt replaced by convPagePtToScreenPt * getPageNumberFromClientPt replaced by getPageNumberFromScreenPt * selectByHighlights replaced by selectWithHighlights * selectBySelection replaced by selectWithSelection * LinkInfo.getX1 ... replaced by LinkInfo.getRect * findText * setViewerCache ### MISC CHANGES * \[Tools] Changed deprecated document lock calls. * \[Tools] Changed quick menu option "Note" to "Text" for free text annotation. ### BUG FIXES * Fixed a potential crash when an attempt to destroy the control is triggered just after openURL() is called. * Fixed a small issue with the PDFViewCtrl password dialog, where hitting the enter key would not submit the password. * Miscellaneous bug fixes and improvements. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.apryse.com/android/changelogs/version-6/v6-1-0.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
