Re png svg images Hi Smallman12q I did switch to using svg format for a while but I found BKChem has some bugs yet to be sorted out i e any compound that has a group with numbers in like NH2 or CF3 comes out with the numbers in huge font that looks totally wrong and out of place Also the letters are sometimes slightly offset and look untidy and svgs can t be edited once made nearly so easily as pngs so I switched back to using pngs as the svg format just doesn t seem so suitable for the kind of images I make Other wikichemists who make lots of images like and also prefer to make pngs so there doesn t seem to be universal consensus on this even though svg may have been adopted as the official wiki standard
