Hello everyone

I want to replace one slide in a PowerPoint presentation where all slides are in "landscape" with one in "portrait".
This is a question that has been asked of me and I can't solve it.
I think only m@rina or Raymond Pentier have the solution.
I can't do it despite the tutorial below from m@rina

https://www.faqword.com/index.php/powerpoint/faq-ppt/environnement/713-peut-on-mixer-plusieurs-formats-de-diapositive-dans-une-meme-presentation-portrait-et-paysage

or even with this tutorial found online

Thank you in advance

Have a good end of the afternoon

Hello everyone,

landscape display allows for optimal presentation of a slideshow on our screens, which are generally wider than they are tall. Changing the orientation of even a single slide results in reducing the slide's size to the height of the screen instead of its width.
Of course, we can fiddle with it, but the result is questionable; the size of a slide is dependent on several criteria, but the average size is 965 x 725 pixels, which is 25.53 x 19.18 cm.

It’s better to use a central area of the slide that has a height equal to the height of the slide, 19.18, which would be 14.45 x 19.18 cm on a black background, as this would correspond to the same display and be much easier to implement.
