Sure Gyorgy  Sarvari,
 
1) Will add layer details in patch as we go ahead 
2) w.r.t patch on master , 
    Imagemagick in master will use magick ( scarthgap and lower version uses convert ) 
    I will push patch for master branch today if possible .
    Also the master imagemagick had an issue for which i have share the patch 
    @ https://lists.openembedded.org/g/openembedded-devel/topic/patch_imagemagick_add/116011305
