Color gradients and borders
Impress does not
support some of the formatting features that PowerPoint does. For
example it does not support three-color gradients, double and triple
borders, or round-dotted borders.
When
importing PowerPoint slides, Impress changes three-color gradients to
two-color, double or triple borders to single and round-dotted
borders to square dots.
To
improve the results of the import, make any necessary adjustments in
PowerPoint before importing files into Impress. Change three-color
gradient fills to two-color. Change double or triple border lines to
a single border line with suitable width. The round-dotted border
lines that are mapped to rectangle-border lines, during import, will
closely resemble the original line style in PowerPoint so that manual
editing should not be necessary.
