HI all

i am using NSPrintOperation with NSView for printing.

portrait pages are print well,

but Landscape printing not done properly please help me for this.

NSPrintOperation* printOperation = [NSPrintOperation printOperationWithView:my_print_view printInfo:printInfo];
        
        [[printOperation printInfo] setPaperSize:printInfo.paperSize];
        
        [[printOperation printInfo] setOrientation:NSPaperOrientationLandscape];
        
        
        [printOperation setCanSpawnSeparateThread:YES];
        [printOperation setShowsPrintPanel:NO];
               
        [printOperation runOperationModalForWindow:window delegate:window didRunSelector:nil contextInfo:nil]

thanks in advance.

Re: my application crashed with this message NSInternalInconsistencyException', reason: 'Printing failed because PMSessionEndDocumentNoDialog() returned -30871.'

Lookup the error code:

kPMOutOfScope - Anonymous | Apple Developer Documentation[^]:
kPMOutOfScope

Your application called this function out of sequence with other printing functions.

Declaration

kPMOutOfScope = -30871

From that I would guess that you have called PMSessionEndDocumentNoDialog() while printing is not - or not anymore - active.

i not called any of fiction related PMSessionEndDocumentNoDialog or kPMOutOfScope

i really don't know what happened even crash log not show any link to my application its shows all link to lib

kPMOutOfScope is just the name of the error (a definition or an enum; should be declared in PMError.h).

PMSessionEndDocumentNoDialog might be called by other printing related functions or by a library (which seems happened in your case). So it may be a bug in that library or your code calls (printing) functions from that library without follwing the library reference documentation.

There should be not so many code lines in your application that are printing related. I would start inspecting them for correct usage of functions by reading the documentation for the used functions. Add code to check function return values (if a start print / preparation function fails for example and you did not detect that but call other printing functions later, they will fail too which might include exceptions). If it is a third party library, contact the supplier or ask in a related forum.

NSMutableArray copy problem

7-Jul-17 20:27

i rotate an image using this

- (NSImage*)imageRotatedByDegrees_Angle:(CGFloat)degrees
{
    [[NSGraphicsContext
      currentContext] setImageInterpolation: NSImageInterpolationNone];
    
    // Calculate the bounds for the rotated image
    // We do this by affine-transforming the bounds rectangle
    NSRect imageBounds = {NSZeroPoint, [self size]};
    NSBezierPath* boundsPath = [NSBezierPath bezierPathWithRect:imageBounds];
    NSAffineTransform* transform = [NSAffineTransform transform];
    [transform rotateByDegrees:-1.0 * degrees];// we want clockwise angles
    [boundsPath transformUsingAffineTransform:transform];
    NSRect rotatedBounds = {NSZeroPoint, [boundsPath bounds].size};
    
    // Center the image within the rotated bounds
    imageBounds.origin.x = NSMidX(rotatedBounds) - (NSWidth(imageBounds) / 2);
    imageBounds.origin.y = NSMidY(rotatedBounds) - (NSHeight(imageBounds) / 2);
    
    NSImage* rotatedImage = [[NSImage alloc] initWithSize:rotatedBounds.size];
    //NSSize new_size=[self size];
    

            NSAffineTransform* transform1 = [NSAffineTransform transform];
       
            [transform1 translateXBy:+(NSWidth(rotatedBounds) / 2)
                                yBy:+(NSHeight(rotatedBounds) / 2)];
            // Do the rotation
            [transform1 rotateByDegrees:-1.0 * degrees];
            

            [transform1 translateXBy:-(NSWidth(rotatedBounds) / 2)
                                yBy:-(NSHeight(rotatedBounds) / 2)];
        
        

         [NSGraphicsContext saveGraphicsState];
     
        
        [[NSGraphicsContext currentContext]
         setImageInterpolation:NSImageInterpolationHigh];
        
        
        [rotatedImage lockFocus];
        
        
            [transform1 concat];
        
            [self drawInRect: imageBounds fromRect:NSZeroRect operation:NSCompositeCopy fraction:1.0];
        
        
         [rotatedImage unlockFocus];
        
        [NSGraphicsContext restoreGraphicsState];
        
            
    return rotatedImage;
    
}

image is rotated but the rotated image is so blurry.

Does anyone know how to solve it?

please help me for this.

Hi all,

i have two different NSMutableArray one is source array and other is backup array,

on some action copy the source array value to backup array.

than continue the changes in source array objects.

but here the backup array objects value automatically changed as i changed in source array.

please help me i don't want to change backup array object even i change in source array object.

thanks in advance.

I do not know Objective-C or Swift, but your description sounds like you have copied the object references instead of the actual content.

Le@rner26-Jun-17 23:05

26-Jun-17 23:05

help me how can i correct this...

Richard MacCutchan26-Jun-17 23:14

26-Jun-17 23:14

As I stated in my previous message, "I do not know Objective-C or Swift". So you need to look at what your code is actually doing and why it is not doing deep copy operations. Hint: you could always try the documentation for whichever language you are using.

You need to clone the contents of the source array. [copy] method of NSMutableArray makes a reference copy with new array variable hence your content in backup array gets updated when you update source array. Use

Objective-C

NSMutableArray initWithArray

to create a clone of source array but with new reference pointer to it. Hope it helps.

Check the documentation of your camera. The manufacturer might also provide an SDK with example code.

If that does not help search the web using the keywords Mac and/or Objective-C and your camera model.
