Saving an NSView to a png file?

Question

I am making a simple program that creates game cards for a game I play. I have sent it out to some friends of mine for testing, but they really want it to save images, not j

First create a TIFF representation of your view:

// Get the data into a bitmap.
[self lockFocus];
rep = [[NSBitmapImageRep alloc] initWithFocusedViewRect:[self bounds]];
[self unlockFocus];
data = [rep TIFFRepresentation];

To support multiple file types, use:

data = [rep representationUsingType:(NSBitmapImageFileType)storageType
properties:(NSDictionary *)properties];

NSBitmapImageFileType is an enum constant specifying a file type for bitmap images. It can be NSBMPFileType, NSGIFFileType, NSJPEGFileType, NSPNGFileType, or NSTIFFFileType.

If you need to customize the NSSavePanel, look into accessory views: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/AppFileMgmt/Articles/ManagingAccessoryViews.html
