Final answer:
Denim is not a predefined texture fill in PowerPoint, but users can create a custom texture fill by using a picture of denim as the fill for shapes or backgrounds.
Step-by-step explanation:
The question "Is denim a texture fill on PowerPoint?" can be answered as follows: Denim is not specifically listed as a predefined texture fill in PowerPoint. However, PowerPoint allows users to create custom texture fills, so you could technically create a denim-like pattern yourself or import an image that resembles denim to use as a fill.
To add a texture fill to a shape or background in PowerPoint, you can select the shape or background, choose the Format option, and then select the Fill icon. From there, you'll see various fill options, including solid colors, gradients, pictures, and textures. While the preset textures include options such as marble, fabric, and paper, denim is not a standard option. However, if you have a denim picture, you can select 'Picture or texture fill' and then 'Insert picture from' to add your custom denim texture.
