[Pharo-users] how to properly create icons

Hi, I've been using using ThemeIcons>>createIconMethodsFromFile:directory: method to create my own icons, however there are some reported problems https://pharo.fogbugz.com/f/cases/15277/some-icons-from-ThemeIcons-are-broke... with the code it generates. My questions are: 1) what exactly is the problem with the generated code? 2) what would then be the correct way to generate it? Glamorous (Moose) icons seem to use different format (using byte array instead of Base64), but I do not see any code that would generate those methods. Thanks, Peter
