hi i am using this code to take screenshot

+(CCRenderTexture*) screenshotWithStartNode:(CCSprite )startNode filename:(NSString)filename { [CCDirector sharedDirector].nextDeltaTimeZero = YES;

CGSize winSize = CGSizeMake(startNode.contentSizeInPixels.width, startNode.contentSizeInPixels.height);

CGSize   photoSize =CGSizeMake(startNode.contentSize.width, winSize.height * startNode.scaleX);
CCRenderTexture* rtx =[CCRenderTexture renderTextureWithWidth:startNode.contentSizeInPixels.width height:startNode.contentSizeInPixels.height];
[rtx begin];

[startNode visit]; [rtx end];

// save as file as PNG
[rtx saveBuffer:[self screenshotPathForFile:filename]
         format:kCCImageFormatPNG];

return rtx;

}
