Re: Toolbar Icon Workflow

I think the issue is more to do with the scaling leaving the lines moved from the pixel boundaries, and with only 24 or 32 pixels to play with, it's pretty noticeable when it blurs across two pixels. Gideon On 27/06/2010, at 8:42 PM, Graham Cox wrote: > > On 27/06/2010, at 11:00 AM, Gideon K

Weak-linking a class

How do I test for the existence of a Cocoa class at runtime that could be absent on an earlier system? The situation is that I want to use NSCache instead of NSMutableDictionary somewhere. The object is created as a singleton when it's first used, but I can't quite see how I should decide which

Re: Toolbar Icon Workflow

I'm just using a standard NSToolbarItem. In any case, I doubt that would change anything if the line is being drawn on two pixels. With the way I am doing it, I can get it right on the pixels every time, and in many cases I want to adjust things a bit between the 24 and 32 pixel images anyway, s

Text rendered in NSImage is fuzzy

I'm trying to render text in System font in an NSImage as shown below. The NSImage is displayed *unscaled* in an NSImageView. However, the text does not look as good as when rendered in an NSView. Is there any way to get crisp clean text in an NSImage? Thanks, Dave // Render an image into a

Re: Text rendered in NSImage is fuzzy

I don't think this is likely to be the problem in this case. Text looks good no matter where you draw it. In this case, I think the problem is more likely either (1) A lack of what Quartz calls font smoothing, more popularly known as subpixel rendering

Re: using UTF-32 in NSString.

Georg, NSString/CFString is conceptually an object wrapping around UTF-16 character array (just like many other string objects). The length 2 returned from your example is, thus, the expected behavior. When you're creating a string with Universal Character Names that containing non-BMP points
