The following code example demonstrates how to convert a slide to image in UWP. This assembly is used to convert Office Chart into Image. This assembly contains the Office Chart Object model and core features needed for chart creation. This assembly contains the core features needed for creating, reading, manipulating a Presentation file. The following assemblies are required in the UWP application to convert the slides as images. PowerPoint slides can be converted to images in UWP by using Essential Presentation library. ToString () + ".jpeg" ) 'Closes the presentation pptxDoc. Height )) 'Saves the image as bitmap bitmap. FromStream ( stream ), New Rectangle ( 0, 0, bitmap. DpiY ) 'Recreates the image in custom size imageGraphics. FromImage ( bitmap ) 'Sets the resolution bitmap.
