Is it possible to change the header height of an NSTextView? - objective-c

Question

I am saving a PDF from an NSTextview and putting a logo in the header. I overrode pageHeader and the logo appears but it is clipped.
Is it possible to change the header height of an NSTextView?
Thanks!
Partial code:
-(IBAction)impLaudo:(id)sender
{
NSPrintInfo *printInfo;
NSPrintInfo *sharedInfo;
NSPrintOperation *printOp;
NSMutableDictionary *printInfoDict;
NSMutableDictionary *sharedDict;
sharedInfo = [NSPrintInfo sharedPrintInfo];
sharedDict = [sharedInfo dictionary];
printInfoDict = [NSMutableDictionary dictionaryWithDictionary:sharedDict];
[printInfoDict setObject:NSPrintSaveJob forKey:NSPrintJobDisposition];
[printInfoDict setObject:[[dirLaudos stringByAppendingString:[estudo stringValue]] stringByAppendingString:#".pdf"] forKey:NSPrintSavePath];
printInfo = [[NSPrintInfo alloc] initWithDictionary: printInfoDict];
[printInfo setHorizontalPagination: NSClipPagination];
[printInfo setVerticalPagination: NSAutoPagination];
[printInfo setVerticallyCentered:NO];
[[printInfo dictionary] setValue:[NSNumber numberWithBool:YES] forKey:NSPrintHeaderAndFooter];
printOp = [NSPrintOperation printOperationWithView:textView printInfo:printInfo];
[printOp setShowsPrintPanel:NO];
[printOp runOperation];
}
#implementation MyTextView
- (NSAttributedString *)pageHeader
{
// Adicionando cabeçalho
NSAttributedString *theHeader = nil;
NSImage * pic = [[NSImage alloc] initWithContentsOfFile:[dirLayout stringByAppendingString:#"cabecalho.jpg"]];
NSTextAttachmentCell *attachmentCell = [[NSTextAttachmentCell alloc] initImageCell:pic];
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
[attachment setAttachmentCell: attachmentCell ];
theHeader = [NSAttributedString attributedStringWithAttachment: attachment];
return theHeader;
}
#end

Instead of overriding -pageHeader, you should override -drawPageBorderWithSize:, which allows you to draw additional marks on the page at print time.
The Size parameter is an NSSize struct containing the size of the current logical page. All you need to do is draw your logo in the correct location:
- (void)drawPageBorderWithSize:(NSSize)pageSize
{
[super drawPageBorderWithSize:pageSize];
//draw your logo
NSPoint offset = NSMakePoint(100.0, 100.0);
NSImage* logo = [NSImage imageNamed:#"logo"];
NSSize logoSize = [logo size];
NSPoint imageOrigin = NSMakePoint(offset.x, pageSize.height - (offset.y + logoSize.height));
[self lockFocus];
[logo drawInRect:NSMakeRect(imageOrigin.x, imageOrigin.y, logoSize.width, logoSize.height)
fromRect:NSZeroRect
operation:NSCompositeSourceOver
fraction:1.0
respectFlipped:YES
hints:nil];
[self unlockFocus];
}
