Timelapse aqcuisition from a Twain camera

[S. Pagakis (IIBEAA)]

Hi

Do the twain acquisition plugins have timelapse functionality?

I mean capturing a movie to disk, either as fast as possible or with a
predefined time wait period between frames?

If not, is there a plugin that can do this?

Thank you

I have an older time-lapse macro that records images to hard disk at user
specified time intervals.  I was written for NIH and also controls a
shutter.

If you want a copy or have other question about it, reply to me off the
list.

Hello,

Like Richard, I made a macro for a friend of mine. As said in the plugin
"Twain", I used a "run" function --To avoid the TWAIN select source
dialog, run from a macro using run("Twain 6", "default")-- like this.


dir=getDirectory("Images path");
Dialog.create("Timelapse");
Dialog.addNumber("Time beetween lapses", 1.0);
Dialog.addNumber("Number of lapses", 2);
Dialog.show();
delay=Dialog.getNumber();
nb=Dialog.getNumber();
i=1;
while(i<=nb){
tps1=getTime();
run("Twain 6", "default");
//run("Lena (47K)");
rename("image"+i);
name=getTitle();
run("Save", "save="+dir+name+".tif");
close();
tps2=getTime();
i++;
wait((1000*delay)-(tps2-tps1));
//write(""+(tps2-tps1));
}


As far as I know, it works fine for her.
