ae scripting
hello,
i am trying to convert a video effect i wrote in processing (java-based) to after effects.
i dont know what after effects scripting is capable of, since i found it to be very bad documented.
here is a list of the things i need after effects script to do in order to get my effect working:
– detect and return the color of a specified pixel
– detect if a specified pixel is alpha channel
– draw lines with a function like this: line(startX,startY,endX,endY)are those things possible?
i guess there might be a way to work around this line stuff with the addLayer function, but that would be pretty unelegant, i think.
if anyone knows a solution for any of the listed issues would be great
thank you

To get at a pixel’s color and alpha data, you’d have to have your script apply the sampleImage() expression to a layer and then have the script read the results.
For the drawing part, your script could create a mask/path and then apply the Stroke effect to it.
