The code below works, but leaks from -dataWithPDFInsideRect

You sure it's a leak (and not just a cache)?

Yes, the leaks are clearly visible in MallocDebug.
Changing the code to this made no difference:

if ([[self window] isMiniaturized]) {
NSImage* anImage;
NSData* pdfData;
NSAutoreleasePool *pool;
pool = [[NSAutoreleasePool alloc] init];
// get the desired image
pdfData = [plotView dataWithPDFInsideRect:[plotView bounds]];
[pdfData retain];
anImage = [[NSImage alloc] initWithData:pdfData];
[[self window] setMiniwindowImage:anImage];
[anImage release];
[pdfData release];
[pool release]; // releases all autoreleased
objects including pdfData
}

In MallocDebug "Definite Leaks" shows a number of 40 byte
blocks while getting and parsing the device plist as follows:

320 bytes in 8 nodes:
malloc
CFAllocatorAllocate
_CFRuntimeCreateInstance
__CFDictionaryInit

+[NSConcretePrintOperation PDFOperationWithView:insideRect:toData:]
+[NSPrintOperation PDFOperationWithView:insideRect:toData:]
-[NSView(NSPrinting) dataWithPDFInsideRect:]

Any more ideas?

Thanks, - Peter
