You'd add an NSBitmapImageRep to an NSImage with -[NSImage
addRepresentation:].
However, an NSImage is not going to be any easier to draw rotated than an
NSBitmapImageRep. You can draw rotated by changing the coordinate system
right before you draw your image, drawing, and putting it back.

I have a question relating NSImage and NSBitmapImageRep. I have a stream of

Thanks, Martin. I ended up doing this:

attributes: attrs];
NSTextStorage* text = self.output.textStorage;
[text beginEditing];
[text appendAttributedString: as];

Hi Rick,
I assume 'output' is your NSTextView. Right?
Firstly, you can append text more easily by doing:
1) [output insertText:mystring];
or
2) [[output textStorage] appendAttributedString:myAttributedString];
To get changes to show up, try
[output didChangeText];
You might not need that

Daniel,
Method swizzling is fine for debugging purposes, but should not be used in
production code. This has already been said by some people who really,
really know what they're talking about.
And it's *very* dangerous to swizzle something on NSString. The first reason
(of many) that comes to mi
When I say it "isn't a native Cocoa app", I mean to say it doesn't use
standard widgets. Anyone who is experienced with Safari and Finder and other
native Mac apps, and tries out Firefox for Mac for the first time, will
notice almost instantly that Firefox is implementing things on their own.
Yes,
Doing this with a class cluster like NSString would be difficult and
especially fragile, as you'd have to make sure to do the appropriate
swizzling for every hidden subclass of NSString that might have its
own implementation of -isEqual:; including those that may be
introduced (or removed) in updat

There was a thread on this list a few days ago about effective method
swizzling into Apple classes. Despite being replete with warnings
about "Don't use it in production code," it IS doable, and very, very
cool, IMHO.

I think to follow the HIG you need to have the application quit with the
home screen button. So that rather means after you have saved or
cancelled, the app should show a simple screen which is clearly 'the
