Folks,
I'm trying to write an Image Filtering service. I checked the docs, but
they are not very helpful. Actually the only reference I was able to
fined is this one:
<
http://developer.apple.com/techpubs/macosx/Cocoa/TasksAndConcepts/ProgrammingTopics/
DrawImages/Concepts/ImageFiltering.html>
"NSImage is designed to automatically take advantage of user-installed
filter services for converting unsupported image file types to supported
image file types. The class method imageFileTypes returns an array of
all file types from which NSImage can create an instance of itself. This
list includes all file types supported by registered subclasses of
NSImageRep, and those types that can be converted to supported file
types through a user-installed filter service."
I've have done a filtering service many many years ago on NeXTSTEP, but
neither can I remember details, nor am I convinced that the old
technique will work unmodified.
I will appreciate if someone can point me to more up-to-date source of
information.
TIA
