This is kind of an obscure problem, but any help would be appreciated :)
GOAL Given an attributed string that contains a numbered list (created using NSTextView's List Panel), I want to programmatically scale the text larger, then save the scaled string as a web archive. PROBLEM When the attributed string for a numbered list is scaled larger (by adjusting the NSFont pointSize), then saved as a web archive, the numbers in the list appear off the screen to the left when the web archive is opened in a web view. A numbered list uses NSParagraphStyle's "headIndent" setting to correctly indent the list text and it appears the indenting isn't working correctly in the webarchive. This problem only occurs when the text is programmatically scaled larger. So I'm not sure if it's a bug in Apple's webarchive generating code or if I need to do something else when scaling the text... SAMPLE PROJECT This simple project clearly demonstrates the problem: http://files.me.com/robchronos/wz7oc5 SCREENSHOT Here's a screenshot from the sample app showing what happens to the numbered list when it's saved as a web archive: http://files.me.com/robchronos/9asl08 CODE Here's the code I use to scale the text and save it as a web archive: // Get the text from the textView NSMutableAttributedString *attributedString = [textView textStorage]; // Loop through all of the font runs in the text and increase the font size by 4X NSUInteger length = [attributedString length]; NSRange attributeRange = NSMakeRange( 0, 0); while (attributeRange.location < length) { NSFont *font = [attributedString attribute:NSFontAttributeName atIndex:attributeRange.location effectiveRange:&attributeRange]; if (font) { [attributedString removeAttribute:NSFontAttributeName range:attributeRange]; [attributedString addAttribute:NSFontAttributeName value:[NSFont fontWithName:[font fontName] size:[font pointSize]*4.0] range:attributeRange]; } attributeRange.location += attributeRange.length; } // Retrieve the webarchive data NSRange range = NSMakeRange(0, [attributedString length]); NSDictionary *dict = [NSDictionary dictionaryWithObject:NSWebArchiveTextDocumentType forKey:NSDocumentTypeDocumentAttribute]; NSError *error = nil; NSData *data = [attributedString dataFromRange:range documentAttributes:dict error:&error]; // Write the webarchive data to a file [data writeToFile:@"/NumberedList.webarchive" atomically:NO]; // Open the webarchive file in the webView [[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"/NumberedList.webarchive"]]]; _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
