Hi,

Known issue in 1.2.x, I believe largely corrected in 1.3.3+

Note the bitmap image export was mainly designed for exporting screen 
shots of documents for web sites. This originally was started as a 
python plug-in iirc.

This may or may not be fixable in 1.2.5, owning to the different way 
the canvas works in 1.2.x vs. 1.3.x
