Hi,
IMHO there is no support for it in SAP (I might be wrong....)
There is however command line utilities that can be used using external commands.
See:
Transaction code SM69 ..
FUNCTION 'SXPG_COMMAND_EXECUTE'
I did a small test with this file https://commons.wikimedia.org/wiki/File:Arctic_big.svg
Using http://www.imagemagick.org/download/binaries/ImageMagick-6.9.3-7-portable-Q16-x86.zip from http://www.imagemagick.org/script/index.php
Command:
convert Arctic_big.svg Arctic_big.png
Got me Arctic_big.png (Attach File)
Regards.
