  1. POHow to auto rotate page when printing NSDocument via NSView?
    text
    copied!<p>I have a NSDocument descendant that I would like to print to a single page - stretched to fit and auto rotated when the page is wider than high. The rendering view determines its bounds based on the content. rectForPage simply returns [self bounds]; knowsPageRange sets range.length = 1 and range.location = 1 and returns YES. Printing is done using the code below.</p> <p>Everything works, execpt the auto -rotation. In the Print Panel I see the preview in the correct shape (wider than high, the correct size etc.), However when I then print, the page is fitted, but in portrait mode, unnecessary scaling down the image. If I do not set printInfo.paperSize, it auto rotates OK, but does not scale, instead it clips the image. Any idea?</p> <p>Additional info: The "View PDF" from the print panel shows the page OK in Preview. Printing from Preview, then shows the image <em>rotated</em> in Preview's Print Panel to match the paper potrait orientation (that is: the landscape image itself appears rotated). This is different from my case where it shows unrotated in the print panel. Printing from Preview's Print Panel then does the correct thing.</p> <pre><code>- (NSPrintOperation *)printOperationWithSettings:(NSDictionary *)printSettings error:(NSError **)outError { MindMapRenderingView *renderingView = [[MindMapRenderingView alloc] initWithMindMap:_mindMap printJobTitle:[_mindMap singleLineTitle]]; NSSize pageSize = [renderingView bounds].size; NSPrintOperation *printOperation = [NSPrintOperation printOperationWithView:renderingView printInfo:[self printInfo]]; [renderingView release]; NSPrintInfo* printInfo = [printOperation printInfo]; [[printInfo dictionary] addEntriesFromDictionary:printSettings]; if (isLandscape) [printInfo setOrientation:NSLandscapeOrientation]; else [printInfo setOrientation:NSPortraitOrientation]; [printInfo setPaperSize:pageSize]; [printInfo setHorizontalPagination:NSFitPagination]; [printInfo setVerticalPagination:NSFitPagination]; return printOperation; } </code></pre>
