actionscript 3 - Flash: combine two BitmapData objects via max( channel ) -


There are two bitmap data objects with my alpha channel. I use the maximum for each channel, using alpha (channel_image_one, channel_image_two) I want to add them to singles. Is there an easy way to get this result?

I do not think the direct betamapadata method is to combine the alpha channel in such a way that with the help of RGB draw () Is implementing a mixing mode, but I do not think if you need a link maximum per channel).

In addition to this, you can make a shader thanks to this task, it is the perfect tool for such manipulations.

Slowly but fast setup in the display If you were not used for PB then you can read / compare the pixels once again with bitmap data .getPixel32 () / setPixel32 (). If you go for this, think about using bitmap data () / unlock () to boost performance.

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
