I just made a video tutorial that shows you how to:

  1. Create a swf with an embedded font.
  2. Create an application and loads that swf and pulls the embedded font from the loaded swf.

This is really simple and really smart if you need to have multiple fonts in your application.

FYI: once again for best video quality use the fullscreen button.

Flash 10’s BitmapData.histogram is really slow?

I have been playing with BitmapData type and getPixelAt to make histograms. When I seen that the flash 10's BitmapData has a new method called histogram I thought it was a new improvement on analyzing BitmapData. Boy was I wrong. it's really really slow and I don't have clue why. Bug maybe??

Here's the code for any one who thinks it maybe that. Whats your thoughts?

FYI: with a for loop and getPixelAt I could still get 25fps at 1ms cycles. Though I have yet to see the frame rate for histogram, I cant event get close to a 1fps.
