possible bug strokewidth IM 6.9.0.5 Q16 Mac OSX
Posted: 2015-01-24T13:43:08-07:00
I think that -strokewidth is not working properly. The lines seem too thin in IM 6 compared to IM 7 when viewed directly. But when overlaid in the browser window below, It may be an anti-aliasing issue instead?
Compare these two results between IM 6 and IM 7 for a strokewidth of 2.[/u]
