Confused with Threshold...

Hi All,

 

 

I want to make some effetcs for the video by capturing it into a bitmap. Capturing video into bitmap and displaying is completed. But the problem is with threshold property of bitmapdata class.

 

I am confused with the threshold. What is the concept behind that thershold? I read it in adobe site itself. But I didn't understand. And also want to know how it is working on bitmapdata. how we can make effects for the bitmap using threshold?

 

 

Please someone help me to sort out this...

 

Thanks in advance

    the basic idea is to replace certain colors in a bitmap with another color.  the colors replaced are those that satisfy a "condition" related to a threshold and a mask.

    I understand What you say. I also did some experiments regarding that one. But I have another problem that How to make mono effect for the bitmapdata using this threshold or some other else. I created black and white effect for the bitmapdata. Creating mono effect is some what difficult for me.

    That is something like Grey Scale Effect. I got it by searching it in google.
