[comp.sys.mac.misc] Icon mask algorithm in ResEdit

francis@csli.Stanford.EDU (Dave Francis) (12/11/90)

Hello netters,

I need to find out the algorithm which Resedit uses to create the icon
mask when editting ICN# resources (the "data->mask" menu item). Is this
published somewhere? I can't seem to figure out the behavior by looking
at different cases.

Thanks for any help,
Dave Francis
