Hello...
An addendum to my previous message:
In addition to using dataWithPDFInsideRect: as I mentioned before,
you also could possibly use the NSString instance method
drawInRect:withAttributes: or the NSAttributedString instance method
drawInRect:, both of which are capable of drawing text correctly
regardless of the (un)flipped state of the view (or image) you are
drawing into.
Of course since you are using custom text drawing code, it's possible
that what you are trying to do isn't simple enough to use the string
drawing methods, but maybe it would be good enough for the dragged
image...

Hello...
For an NSImage, the "flipped" state refers to the destination view
where the image will be composited, not the source view. So, all
you probably have to do is not call setFlipped:YES...
Well that's just what I thaught. Unfortunately it doesn't work. In
an ordinary NSView toggeling the flipped state affects the order of
multiline text rendering. If its not flipped the text comes out
like this:
out like this
the text comes
Setting it to flipped makes Cocoas text rendering put the lines in
the correct order. When using the same code to draw text in an
NSImage that is not flipped. The text comes out the same way. That
is:
out like this
the text comes
This is clearly not what I want. But if I set the the flipped state
to true in an NSImage I don't get the same result as in an NSView.
Instead the finished graphic (the pixels) comes out upside down.
This is not what I want either.
Thank you anyway. If you have any ideas please let me know.
