Drawing Arrows with a Macro?

[Adam Cliffe]

Does anyone know a good way of drawing an arrow using the Arrow tool with a macro?
I've tried:

setTool("arrow");
makeLine(169, 193, 171, 194);
run("Draw", "slice");

but it doesn't work...

thanks

Adam

Adam,

include this function in your macro:

function makeArrow(x,y,x1,y1) {
eval('script','img = IJ.getImage();a= new
Arrow('+x+','+y+','+x1+','+y1+');img.setRoi(a);');
}

You can then use the makeArrow  (x,y,x1,y1) function that will draw an arrow
between to two given points, using the curent arrows settings.

Hi Jerome,

Thanks for the mail, I've tried the function and I just get this
message:
ReferenceError: "newArrow" is not defined. (<Unknown source>#1) in
<Unknown source> at line number 1

any idea what's going wrong?

thanks

Adam

Adam,
use the whole code, including the 'function' keyword that defines the new
function. A full example macro would look like this :


// example macro with the custom makeArrow function
run("Clown (14K)");
makeArrow(70, 23, 52, 109);
function makeArrow(x,y,x1,y1) {
eval('script','img = IJ.getImage();a= new
Arrow('+x+','+y+','+x1+','+y1+');img.setRoi(a);');
}
// end of macro
