[Mediawiki-l] .png image text font mis-scaled

I've run into a problem with images I'm converting from another
source. The most accurate intermediate format seamed to be .png,
however; I've run into a repeated problem with some images display. On
certain images, some of the text rendered has been misscaled and is
inconsistant with the surrounding image. The text is correctly located
on the displayed image. At first, I thought this was a problem with
the software generating the .png file from its source. These are
ChemDraw format images and are being converted by ChemDraw. In further
looking at the intermediate, I find I can correctly view the .png file
with other windows utilities without the font scale problem. These
utilities Paint and Windows Photo Gallery also have no problem scaling
the image. I have also attempted enabling .svg image format hoping it
would be a convenient intermediate, but; the added work to support
browsers without native .svg gave me pause.

Can anyone familiar with the .png scaling process comment on why (only
certain) text in .png files does not scale properly? I'm using
MediaWiki 1.15.1. Thanks for any help.
