1 2 Android PdfRendererBasic Sample 3 =================================== 4 5 This sample demonstrates how to display PDF document on screen using 6 the PdfRenderer introduced in Android 5.0 Lollipop. 7 8 Introduction 9 ------------ 10 11 You can now render PDF document pages into bitmap images for printing by using 12 the new [PdfRenderer][1] class. You must specify a [ParcelFileDescriptor][2] 13 that is seekable (that is, the content can be randomly accessed) on which the 14 system writes the the printable content. Your app can obtain a page for 15 rendering with [openPage()][3], then call [render()][4] to turn the opened 16 [PdfRenderer.Page][5] into a bitmap. 17 18 This sample loads the PDF from assets. Contents of assets are compressed by 19 default, but we disable it since PdfRenderer class cannot handle it. 20 21 ```groovy 22 android { 23 aaptOptions { 24 noCompress "pdf" 25 } 26 } 27 ``` 28 29 [1]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html 30 [2]: https://developer.android.com/reference/android/os/ParcelFileDescriptor.html 31 [3]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html#openPage(int) 32 [4]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html#render(android.graphics.Bitmap, android.graphics.Rect, android.graphics.Matrix, int) 33 [5]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html 34 35 Pre-requisites 36 -------------- 37 38 - Android SDK 24 39 - Android Build Tools v24.0.1 40 - Android Support Repository 41 42 Screenshots 43 ------------- 44 45 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 46 47 Getting Started 48 --------------- 49 50 This sample uses the Gradle build system.
