Macro command setLineWidth does not work

[jumpfunky]

Hi,

if I try to manipulate the line width of the line selection tool using
the macro command "setLineWidth" it doesnt work. The line width does not
change.

A bug? (ImageJ 1.48p).

Cheers,
Thorsten

Thorsten,

perhaps you should set

        setLineWidth( widthInPixel );

_before_ actually drawing the line.

Hi Herbie!

Thats exacly what I've done.

But this command doesn't affect the line selection tool but just the
command "drawLine".
The command
 run("Line Width...", "line=5");  
seems to work!

Thanks,
Thorsten

The setLineWidth() macro function sets the line width used by drawLine(), lineTo(), drawRect() and drawOval(). Use Roi.setStrokeWidth() to set the width of line selections. Here is an example that creates a line selection and sets its width to 25 and its color to a transparent blue.

  requires("1.48h");
  newImage("Untitled", "8-bit random", 400, 400, 1);
  makeLine(102,124,213,114,286,188,227,289);
  Roi.setStrokeWidth(25);
  Roi.setStrokeColor("550000ff");

The Roi.* macro functions, added in v1.48h, are described at:
