Hi guys, I'm a newbie and I'm reading a book which shows the two
different option to link programmatically a control to an action:
SEL mySelector;
mySelector = @selector(methodName:);
[myButton setAction:mySelector];
OR
SEL mySelector;
mySelector = NSSelectorFromString(@methodName:);

Hi guys, I would like to create an Interface which will be eventually
implemented by some classes. I am a bit confused here, in objective-c
the .h files are basically already interfaces. Ok, but how could a .m
file implements more than one? I couldn't find any document explaining
how to implements

Hi guys, is there some good tutorial around about how to manipulate
bitmaps in Cocoa?
I would be interested on:
- copy portion of image over another with a mask (this should be
pretty straight forward with quartz2d)
- apply threshold
- apply effects like blur
Not sure if some of this, like the
should happen in the view context? Should I extend
the image view and handle the routing internally?
Thanks, chr

Thanks Mike, I can't use NSImage (guess why) but a subset. Btw, the
problem I have is that I have a view which contains an image. I would
like to draw in the image, not in the container view so I need to
provide to the draw method the image
I think I found what to do. I need to create a bitmap context from the
bitmap and drawing there. It makes sense that everything drawn is
handled by contexts of course, I'm just a bit concerned about
performances.

Hi guys, I'm trying to render the stage with a default interval. When
the needed time to render the scene is higher than the interval
itself, the application doesn't process anymore the mouse events. I'm
setting the timer once with [NSTimer scheduledTimerWithTimeInterval].
I'm thinking of
It seems my problem was that I was putting as interval 1/10 not
0.1 or 1.0/10, this presumebly was as putting interval 0. That's
why the continuous loop :)

I'm modifying frequently the pixels of the images, the way I found is
creating a copy of the data
(CGDataProviderCopyData(CGImageGetDataProvider(image));) modify the
pixels and then create a new one. I'm facing performance issues and I
fear that all this allocating and deallocating is not helping.

Where your image come from, why do you need a CGImageRef and what are you
trying to do with it ?

Are these pixel operations not something which can be accomplished by
changing the way you draw, for example using compositing modes?
Alternatively, do you have access to Core Image

If you've created a bitmap context, then you should already own the

bitmap data buffer. You can just manipulate it directly without making a
copy (via a CGImage).
How could I access its buffer?

I'm trying to calculate the width of a text and the same code I used
in the past in a drawRect routine in a view to its

course is the context, in this case I created a bitmap context and the

Probably my method was working but sizeWithFont is definitely the one
to be used.
