Java displaying TIF
Locked
 
|
Does anyone know where I can find a java example of using the imageJ library
to display a .tif image? Is it possible to use this library to display them within your own applications or must you use the imagej interface always? Thanks, Jack |

Hi,
maybe I´m totally mistaken, but loading a TIFF into ImageJ puts it in an "Image Processor" which already has a large amount of functionality, so I assume you would end up with importing a large part of ImageJ anyhow. If you "only" want to read and display a TIFF in Java, what about this library: (just looked it up, did not myself test it) http://www.lizardworks.com/java.html You can use ImageJ resp. it´s library in a Java applet AFAIK, there should be an example somewhere Mit freundlichen Grüßen / Best regards Joachim Wesner Leica Microsystems CMS GmbH | GmbH mit Sitz in Wetzlar | Amtsgericht Wetzlar HRB 2432 Geschäftsführer: Dr. Stefan Traeger | Dr. Wolf-Otto Reuter | Dr. David Roy Martyr | Colin Davis Jack Breon <appdevelopment@W ORLDNET.ATT.NET> An Gesendet von: [hidden email] ImageJ Interest Kopie Group <[hidden email].

To read a TIFF file, several options to suggest:
You might use ij.io.FileOpener to create an ImagePlus, and then use the BufferedImageCreator class from the imageio plugin at http://ij-plugins.sourceforge.net/plugins/imageio/index.html. Or use the javax.imageio package. Here's an example: http://www.exampledepot.com/egs/javax.imageio/BasicImageRead.html |

Here is a Java program that uses ImageJ as a library to display a
TIFF file: import ij.*; import java.awt.*; public class Test { public static void main(String[] args) { ImagePlus imp = IJ.openImage(args[0]); imp.show(); } } It also opens and displays any other format supported by ImageJ, including JPEG, PNG, GIF, BMP, PGM, DICOM and FITS. I compiled and ran it using javac -cp ij.jar Test.java java -cp ij.jar:. Test blobs.tif which assumes ij.jar and blobs.tif are in the current directory. To get an AWT image use ImagePlus imp = IJ.openImage(args[0]); Image img = imp.getImage(); Note that ImageJ only opens uncompressed TIFFs or LZW compressed TIFFs. -wayne On Jan 26, 2008, at 6:12 PM, Jack Breon wrote: > Does anyone know where I can find a java example of using the > imageJ library > to display a .tif image? > > Is it possible to use this library to display them within your own > applications or must you use the imagej interface always? > > > > Thanks, > > Jack |

Hello everybody!
I have following questions: I have microscopic picture of cells. I want to measure cell's diameter. I wonder, what is the best way to do that: The line of already measured cell must be seen, even i measure another cell. This is not possible with tool Straight line selection... Then, it is possible that result are immediate shown without pressing all the time Measure command?? The task is simple, so I hope is there any good solution...or some good plug-in exists for that... Thank you for your time and answers! Marko |

Just hit Ctrl-D to draw the line on the image.
Just hit Ctrl-M to measure the line.

Here is one way to do this:
1. Open the ROI Manager. 3. Click "Show All". 4. For each cell, create a selection and press "t" (Edit>Selection>Add to Manager). 5. Click "Measure" in the ROI Manager. -wayne On Jan 28, 2008, at 5:15 AM, Marko Usaj wrote: > Hello everybody! > > I have following questions: > > I have microscopic picture of cells.

Hi Dear All,
I have a simple question for experts like you (it's difficult so far for me) I have a picture in not rectangular or square form. When I open it and convert it to binary then measure the porosity it takes the area of whole picture (picture itself+plus white background that fills the rectangular. Is there any way to get porosity measurement for irregular shapes excluding the background? Thanks in advance... Omer N.

Dear Cora,
First threshold your image and later click "Set Measurements" under "Analyze" menu Select only the area for your measurements. Then select the area which you want to measure by the "Freehand selection tool" and click "Analyze particles" under "Analyze" menu. If you want to exclude area on edges of your selection you will also find a box about this on the opened window.
