Impress does not appear to have object wrap available. The manual for Writer refers to menu items not available in Impress. Manual page:
Steps to Reproduce:
1. Add an object or image to a presentation
2. Follow directions for text-wrapping in the Writer manual
3. Observe missing menu items and functionality
Text wrap is not possible for objects in Impress
Text wrap is available and functions as it does in Writer
User Profile Reset: No
Presentations are visual by nature and therefore text-wrapping is an extremely valuable feature for Impress.

Impress does not have continuous text as Writer it has, but has only single graphic objects. Your request is the same as if you would intersect a "Text-box"-shape (that form the T icon) and a circle in Writer.
Nevertheless it is a valid request and has been already requested before.
