A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
The Why: I am an artist. Very often, as an aid to drawing compositions, a grid is placed on the source photo to help with alignment of elements on the free sketch of the target painting.
The Workaround: I've found that using the "Insert/Tables" command and getting rid of the table's fill and special line formatting, I can superimpose a grid on the artwork of any size and resolution I desire.
Thanks to all who responded and help me think about this issue. I hope this will be helpful to others.
