osx - Embossing effect in the menubar for NSStatusItem -

i'm developing application icon in mac os status bar.

i add icon with:

self.statusitem = [[nsstatusbar systemstatusbar] statusitemwithlength:nsvariablestatusitemlength]; nsbundle *bundle = [nsbundle mainbundle]; nsimage *connectedimage = [[nsimage alloc] initwithcontentsoffile: [bundle pathforresource: @"drawing" oftype: @"pdf"]]; [self.statusitem setimage:disconnectedimage]; 

it shows fine without traditional embossing (or shadow) effect apple system status items have:

you can see on left icon, , on right apple icon effect.

i have tried different image formats without luck. effect present if use internal icon, that:

[self.statusitem setimage:[nsimage imagenamed:nsimagenamelocklockedtemplate]]; 

should add effect myself image or there obvious i'm missing?

thank you!

you need do

[myimage settemplate:yes]; 

then system indent you.
