draw lines in image

Hello!

This is my first post. I want to know how can I draw a line in the
images. I'm opening an image (.jpg) and apply my algorithm (hough), so
finally I want to draw lines in my result image. Can anyone help me with
this. I've been several hours in this.

Best!

Francisco.

Re: draw lines in image

Hi Francisco,

> I want to draw lines in my result image.

Click the line tool (fifth from left in the toolbar), draw a line on the
image by clicking and dragging with the mouse, then run Edit > Draw to make
it permanent on the image.

In a macro, the code is something like:

makeLine(216, 14, 35, 91);
setForegroundColor(255, 255, 255);
run("Draw");

I found this code easily by running Plugins > Macros > Record... to launch
the Macro Recorder, then repeating the manual steps I mentioned above.

HTH,
Curtis

Re: draw lines in image

Hi Francisco,

In addition to this if you right mouse click on this line tool you can select the type of line you want to use; straight line, segmented line, freehand or arrow.

Re: draw lines in image

Hi!

Thanks for the answers, but i'm trying to draw lines from the code. With
your help i'm trying to search the function to draw lines automatically
from my code.

Best!

Re: draw lines in image

hello Francisco,
Help>Macro Functions, searching for 'line':

lineTo(x, y)
Draws a line from current location to (x,y) . See also: Overlay.lineTo.

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. You can create segmented line selections by specifying more than two coordinate pairs, for examplemakeLine(25,34,44,19,69,30,71,56).

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

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. See also: Overlay.drawLine.

and, depending on what you are trying to do:
getCursorLoc(x, y, z, modifiers)
Returns the cursor location in pixels and the mouse event modifier flags. The zcoordinate is zero for 2D images. For stacks, it is one less than the slice number. UsetoScaled(x,y) to scale the coordinates. For examples, see the GetCursorLocDemo and the GetCursorLocDemoTool macros.

Re: draw lines in image

Hi,

If you are doing plugin programming, you may use the following code I
posted a while ago:

Overlay overlay = new Overlay();
Roi roi = new Line(startX, startY, endX, endY);
overlay.add(roi);
imp.setOverlay(overlay);
Cheers

quantify cell clustering

Dear all,

I would like to ask your advice if an how I could use Image J to quantify
cell clustering. There is an internatially used assay where cells (CHO
cells) clustering in response to pertussis toxin. The clustering is
measured visually by eye, which is rather subjective and we are searching
for an more objective parameter. Some picture of clustering (image 29),
normal cells (image 34) and inbetween (image 35 and 36) are attatched to
the email. If anyone has and idea on which parameter we can use and how it
can be measured with Image J, I would appreciate it!

Re: quantify cell clustering

If you are going to draw line or any other object on image to highlight or complement the image content, such as, ellipse, rubber stamp, rectangle, etc., you can integrate an image annotator on your windows system.

Re: draw lines in image

In reply to this post by Francisco Soto

Recently, I had to write code in an ImageJ Macro to draw a segmented line on an image. The coordinates for the segments of the line were stored in two arrays (Segement_x[] and Segment_y[]) and there were NumberOfSegmentPoints in the arrays.

I wanted to use the macro command makeLine, put all of the segment points in a string, and execute it all at once. After some experimentation, the following code did the trick:
//*******************************
// Draw a segmented line from arrays
if( NumberOfSegmentPoints>1 ) {
AStr = "makeLine(" + Segment_x[0] + "," + Segment_y[0];
for( i=1; i<NumberOfSegmentPoints; i++) {
AStr = AStr + "," + Segment_x[i] + "," + Segment_y[i];
}
AStr = AStr + ")";
eval(AStr);
}
//*******************************

The big trick was using the <b>eval macro command to interpret the string.
