Convert POTM to BMP in PHP

Aspose.Slides for PHP via Java can load a macro-enabled PowerPoint POTM 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. BMP files contain rendered slide content and do not retain the VBA project from the source template.

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

Console/Terminal

> composer require aspose/slides
