Did you set the width/hight properties? Cheers Hi Kodiak,

this looks indeed strange, but could be completely normal – I had to see the source image.

Did you set the width/hight properties?

Cheers

Really great work on this filter. I would like to use it on embedded font text in order to smooth the letters for printing. So I apply it on a bitmapdata with alpha. On some parts of my image I get holes in obliques... I let you have a look: http://imm.io/7f0D Hello!

While I knew that SmartAA 'could' work well for fonts, I never thought about using it as a workaround for embedding - great idea! Saw your blog post, cool stuff.

I'm using SmartAA not only for Images but also for TLF device fonts. Thanx a lot! Great work!

So I'll try your code and keep you updated. thx thx a lot.

I am glad if my code can improve your project and I would be very interested in seeing the result. Cheers! Hi Francoir,

Would it be ok for me to use your code in it ? I would leave the credit to you http://www.francois-tarlier.com/blog/index.php/2010/03/update-cubic-lens-distortion-pixel-bender-shader-for-ae-with-scale-chroamtic-aberration/ Thx Hi,

This might be really useful for preloading high res images using low res and upscaling x2. Or doing the smoothing on a whole bunch of stuffs at once instead of separate instances with the built it flash bitmap smoothing. I think flash by default anti alias all the bitmap content with quality high, i wonder if you put it back to low and use this filter, this might lead to performance and visual improvements. To check.Anyway. Very useful to me.Thanks a lot. Didn’t understand everything about how it works, but works really well!

Very nice example - is this SmartSSAO working there? I made some promising tests with Papervision but decided not to post them because kode80 was faster and pretty much nailed the thing. And yes I work as a freelancer - will contact you via mail (info@smart-page.net). I see you are using kode80´s depthshader.

True, shader programming sometimes seams quite tricky because of the limited language and the math involved, but in the end its just juggling with colors ...and a lot of fun :) I am sure you can.

I am no hardcore programmer and I wish I can be that smart like you to do the same thing. :) I really like you using pixel bender to achieve those graphic algorithms in other languages.

I think you just optimized it as far as possible without writing it directly in assembler :D You may have noticed, I didn´t even try to speed it up. I was worried over the performance from the beginning, thats why I went with the M.N. as I assumed it would be faster than the Lanczos (no sine)... also it doesn´t sharpen that much. But than it became clear to me that it wouldn´t be quite fast enaugh for flash anyway so I stopped caring - it was late :) On the other hand it might work fine for a small or rarely redrawed area... and who can argue with optimized code? I updated the shader with your improvements. Much appreciated - thx! Nicely done.
