Ajouter des images à une diapositive

Cette page explique comment ajouter des images à une présentation Google Slides existante. Lorsque vous ajoutez une image, vous fournissez à l'API Google Slides une URL publiquement accessible vers l'image.

À propos des images

Les images de l'API Slides sont un type d'élément de page. Comme pour tout élément de page, vous spécifiez la taille visuelle et la position de l'image à l'aide des propriétés size et transform de PageElement. Pour savoir comment dimensionner et positionner correctement votre image, consultez la section Formes de taille et de position.

Pour ajouter une image, utilisez la méthode CreateImageRequest. Les images doivent être inférieures à 50 Mo, ne pas dépasser 25 mégapixels et être au format PNG, JPEG ou GIF.

Exemple

Cet exemple utilise l'API Slides pour ajouter une image à une présentation.
