Your images have no transparency. Always post your original images (so we can use it for processing). Also provide your IM version and platform. The way to handle this is by dilating the alpha channel using -morphology.
If using IM 7 change convert to magick.
Code: Select all
convert image \( -clone -fill blue -colorize 100 \) \( -clone -alpha extract -morphology dilate disk:5 \) -alpha off -compose copy_opacity -composite result.png
