I am noticing the rightmost and bottommost edges of some characters rendered in MyriadPro-Bold.otf with bbutil_render_text() are being clipped. The amount being clipped appears to be 1 pixel off the right and bottom for some characters. I am not seeing clipping with any other fonts that I have tried, just MyriadPro-Bold.otf so far. Is anyone else seeing this?

Which characters do you see clipping on? HelloWorldDisplay uses MyriadPro-Bold.otf and I dont see any clipping.

Also, is this on a device or simulator?

PS I might need glasses though.

I will PM you tonight with a screenshot. It seems to be showing up pretty clearly against my background. I'm seeing it in the device but I will try to see how it renders on the sim.

Thanks

Any solution to this issue yet? We're encountering the same problem with different fonts (e.g. akzidenz-grotesk-roman.ttf) in one of our Apps.

I am curious as to why you are using bbutil sample code to render text as opposed to cascades.

[guru2000at]

make cascades available for the pb and we are going to use it ...

And what about Qt? That's available now.

[guru2000at]

you are right, but we do not want to use the qt framework. The NDK provides a class for simple rendering of text.

[HorizonXP]

But bbutil is not a part of the NDK, it's simply a helper class that is used in the samples. It's likely not something under active development, so it's likely unwise to use as the basis for an app.

If you're adamant about avoid Qt, then look at the freetype library. We've used it on the BB-Py Project, and it works just fine for rendering text.

[dtomilovskiy]

Bear in mind that it is a part of several samples - not a full text rendering engine as there are several intricacies when it comes to rendering text with GL/Freetype. Hence bbutil is not a general-purpose engine, but merely a collection of useful code that would otherwise be replicated over several of our samples.

Also, note that there exist open-source text engines that you can make use of. Not sure how big your app is, but you will quickly run into problems with non-english fonts both in terms of resource limitations and layouting with bbutil.

That being said, could you please PM me a distilled example that reproduces edge clipping problem? If I recall this correctly, superdirt and I could not reproduce this problem reliably. I'll look into this issue at my earliest convenience.
