Is it possible to add CGContextSetCharacterSpacing(context, n) to FXLabel?

[kyleplattner]

Is it possible to add CGContextSetCharacterSpacing(context, n) to FXLabel? If so, how?

[nicklockwood]

I didn't know that method existed. Seems like it would make a handy addition to the library.

The biggest problem seems to be working out the size of the text because you can't use the simple NSString size functions if you're using a non-standard letter spacing.

I'll look at adding it to the core library myself, but in the meantime, here's a stackoverflow thread with some possible solutions (I notice you commented on another stackoverflow thread):

I tried adding in the line and couldn't get any of my FXLabels to respond to it (it is very possible I was adding it in the wrong spot). Please let me know as soon as you get something, I am very interested in adding this in. Thanks,

Kyle

I've managed to get it working. The problem is that you have to use CGContextShowTextAtPoint to display the text instead of the NSString drawInRect methods, and that seems to be much more primitive. In addition to not giving you the final size before drawing, it also doesn't provide any options for wrapping or text alignment.

I'll keep looking into it, but it seems that the only way to take advantage of this feature without losing existing functionality is to write my own text layout engine.

[kyleplattner]

Would you be willing to share the code you used to get it working?

Here you go - it's buggy though, I need to tie the adjusted text size calculation in earlier in the process so that the effects are applied over the whole width of the string:

Thanks, it appears to work fine for me. Let me know when you get ironed out completely though if you would.

Nick, Do you know if it is possible to use FXLabel inside of a UITextField?

Hi Kyle,

That's tricky. I've not tried it, but you might be able to use a subclass or category on UITextField to replace some of the internal UILabels with FXLabels, but looking at the header for UITextField it looks like a lot of the heavy listing is done with a private class called UITextFieldLabel, which you can't replace with an FXLabel, and attempting to do so would probably require you to make private API calls.

So the short answer is no.

[kyleplattner]

Thanks for the reply. Also while I am at it: is there anyway to clean up aliasing seen when using FXLabel?

Have you tried increasing the oversampling value?

[kyleplattner]

I have not, how do I determine what to set it at?

Erm... by reading the documentation?

"For best results, set oversampling to a power of two, i.e. 1, 2, 4, 8, 16, etc. For performance reasons, you should use the lowest value that yields acceptable results."

Basically, try a value of 2 and see if your aliasing goes away. If it doesn't, try 4, and so on.

Nick, With the code you gave us from the link below to accommodate character spacing right justified doesn't seem to behave correctly with applied effects. Do you have any ideas on how to fix this?

The version I forked to add character spacing predates the edge insets feature that allows the effects to work properly with right justification. I'll update it at some point when I have some spare time.

Just noticed that you posted an update to FXLabel. Do you anticipate being able to add character spacing officially in the near future? I am still using an old version you had put together to include this and I would love to update.

[nicklockwood]

Yes, but it will be a major change and I've been concentrating on quick wins and bug fixes for the time being.

It's on my todo-list for FXLabel 1.4, but the version I made for you was a bit of a hack and I'm not ready to merge it into the main release yet because it would break too many things.

[nicklockwood]

Sorry, I didn't manage to squeeze this into 1.4. I did make a number of internal enhancements to the layout code that will make it easier to add this in future however. I'll try for the next version.

[kyleplattner]

Do you have an estimation of when it will be done? I am still running on a really old one-off version and have a tough time keeping up to date with the latest changes. Thanks.

Is there a good way to hack character spacing into the current version so I can take advantage of your recent fixes?

This is now implemented in the current 1.5 beta. I've not done any performance tuning yet, so let me know if it's noticeably slower to render than before.

[kyleplattner]

Thanks so much. I can't wait to try this.

Sure. Email it to support at charcoaldesign dot co dot uk and I'll take a look.
