Convert POTX to BMP in PHP

Aspose.Slides for PHP via Java can load a PowerPoint POTX template and render each slide as a BMP image without Microsoft PowerPoint.

Call getImage for each slide and save the rendered image with ImageFormat::Bmp. A scale factor of 2.0 produces an image at twice the slide’s default rendering dimensions.

You can install the library from Composer using the following command:

Console/Terminal

> composer require aspose/slides
