Hello World Application using Aspose.Slides

Steps to Create Hello World Application

In this simple application, we will create a PowerPoint presentation having Hello World text at a specified position of a slide. Please follow the steps below to create Hello World application by using Aspose.Slides for C++ API:

• Create an instance of Presentation class
• Obtain the reference of the first slide in the presentation which is created on instantiation of Presentation.
• Add an AutoShape with ShapeType as Rectangle at a specified position of the slide.
• Add a TextFrame to the AutoShape containing Hello World as default text
• Change the Text Color to Black as it is white by default and is not visible on the slide with white background
• Change the Line Color of the shape to white in order to hide the shape border
• Remove the default Fill Format of the shape
• Finally, write the presentation to desired file format using the Presentation object

The implementation of above steps is demonstrated below in an example.

    portionFillFormat->set_FillType(FillType::Solid);
