I seem to have gotten my screenshot code to become stable. I did this by getting the bitmap data through ApplicationServices framework, instead of through NSBitmapImageRep. Unfortunately, I still don't understand why the old code did not work, so if anyone figures it out, I'd be interested.
The new code is below.
Sami
private Screenshot _getScreenshot(int windowId) { NSRect nullRect = new NSRect(new NSPoint(Double.POSITIVE_INFINITY, Double.POSITIVE_INFINITY), new NSSize(0, 0));
ID imageRef = QuartzLibrary.INSTANCE.CGWindowListCreateImage(nullRect, QuartzLibrary.kCGWindowListOptionIncludingWindow, windowId, QuartzLibrary.kCGWindowImageBoundsIgnoreFraming);
long width = AppLibrary.INSTANCE.CGImageGetWidth(imageRef); long height = AppLibrary.INSTANCE.CGImageGetHeight(imageRef); long bytesPerRow = AppLibrary.INSTANCE.CGImageGetBytesPerRow(imageRef);
ID nsdataRef = AppLibrary.INSTANCE.CGDataProviderCopyData(AppLibrary.INSTANCE.CGImageGetDataProvider(imageRef)); Foundation.cfRelease(imageRef); NSData nsdata = Rococoa.wrap(nsdataRef, NSData.class, false);
byte[] data = new byte[nsdata.length()]; nsdata.getBytes(data);
return new Screenshot(width, height, bytesPerRow, data); }
