Hi,

With me, drawing vertical lines still did not work manually!! Maybe it is my
fault!

But I found a work-around by filling a small retangle.
Please allow me one last question ...

How can I  transform all pictures in a current file? ... run("Open next") did
not work ...

What I have (for one file)..

open("D:\\DrArbeit\\Rhizoskopie\\Analysierte Bilder\\Ab\\Versuch
Linie\\AbEiDa_T008_L000_01.09.2006_1200_014_Bor.JPG");
makeRectangle(408, 4, 12, 3176);
run("Fill");
makeRectangle(1504, 4, 12, 3168);
run("Fill");
saveAs("Jpeg", "D:\\DrArbeit\\Rhizoskopie\\Analysierte Bilder\\Ab\\Versuch
Linie\\NEU\\AbEiDa_T008_L000_01.09.2006_1200_014_Bor.jpg");

close();




Thanks a lot in advance!
All the best,

Boris

Hi,

Not sure what is the "Draw" (Strg D) function.
I think that you may be applying the wrong functions.

Have a look at:
http://rsbweb.nih.gov/ij/developer/macro/functions.html


I think that you need:

drawLine(x1, y1, x2, y2)
 Draws a line between (x1, y1) and (x2, y2). Use setColor() to specify the
color of the line and setLineWidth() to vary the line width.

or

makeLine(x1, y1, x2, y2)
 Creates a new straight line selection. The origin (0,0) is assumed to be the
upper left corner of the image. Coordinates are in pixels. With ImageJ 1.35b
and letter, you can create segmented line selections by specifying more than
two coordinate, for example makeLine(25,34,44,19,69,30,71,56).

or

makeLine(x1, y1, x2, y2, lineWidth)
 Creates a straight line selection with the specified width. Requires 1.38u.
See also: getLine.
