How to Extract Entire Text from PowerPoint Presentation inside Android Apps
This technical tip explains how Android developers can extract entire text from a presentation inside Android applications using Aspose.Slides for Android. You can extract text from presentation using Aspose.Slides for Android. The text inside a presentation is located in two types of objects namely TextHolder and TextFrame. TextHolder is a special Placeholder that holds text and TextFrame is actually a TextBox which you create using MS-PowerPoint. Aspose.Slides for Android has designed the layout of TextHolder and TextFrame almost identical so that programmers could access and manipulate text easily.
