How to save an image in different formats

Hello,I'm new in imagej, and i want to make a field/label with an option to save an image in jpg,tiff,jpeg .How to do that,how to implement in the following code.Thanks.
import java.io.File;

import ij.IJ;

import ij.ImagePlus;

import ij.plugin.PlugIn;

importij.process.ImageProcessor;

//This plugin shows the basicstructure of a code.

public class Open_Image implements PlugIn {

       public void run(String arg) { //Method Belongingto PlugIn Implementation



              StringmyDirector1 = IJ.getDirectory("Select SourceFolder...");        //This pluginopens the select folder window in ImageJ

              if (myDirector1==null) return;                                                                              //If not sourcefolder is selected the plugin stops here

              String[]myListSources = new File(myDirector1).list();                                        //This string contains all the filesnames in the source folder

              if (myListSources==null) return;

              IJ.log("The sourceimage folder chosen was"+myDirector1);                              //This command opens the log window andwrites on the variables on it.



              StringmyDirector2 = IJ.getDirectory("Select SavingFolder...");

              if (myDirector2==null) return;                                                                              //If not savingfolder is selected the plugin stops here

              IJ.log("The savingfolder chosen was"+myDirector2);



              int Image;

              for (Image = 0; Image < myListSources.length; Image++) {



                     IJ.showProgress(Image,myListSources.length);                                    //This command sets magnitude the progressbar on ImageJ

                     IJ.log((Image+1)+":"+myListSources[Image]);

                     IJ.showStatus(Image+"/"+myListSources.length);                                         //This command sets a text in theImageJ status bar



                           ImagePlusmyImPlus = IJ.openImage(myDirector1+myListSources[Image]);

                           myImPlus.show();                                                                               //This commandopens a window with the corresponding ImagePlus

                           ImageProcessormyIp = myImPlus.getProcessor();

                           myImPlus.updateAndDraw();



              IJ.log("Completed");

       }

Re: How to save an image in different formats

Good day Daniel,

is it necessary for you to use an ImageJ-PlugIn for your purpose?

If not, you may have a look the ImageJ-Macro language which is much easier:
<http://rsb.info.nih.gov/ij/developer/index.html>

"want to make a field/label with an option to save an image"

Could you please explain in more detail what you want and perhaps you
can supply access to a typical example image, so we can see where the
label is to be put.

Best

Re: How to save an image in different formats

In reply to this post by sabau daniel

Daniel,

is this (example) macro

//
newImage("Example", "8-bit random", 128, 128, 1);
format = getString("Please enter either 'tiff', 'jpeg', or 'png'
without quotation marks.", "tiff");
saveAs(format);
run("Close");
//

what you are looking for?
Open an empty macro text window (Plugins > New > Macro) and copy the
above to it and run...

OK Daniel,

my previous code snippet does what you want but without the drop-down menu.
Here is a polished version:

//
newImage( "Example", "8-bit random", 128, 128, 1 );
items = newArray( "TIFF","JPEG","PNG" );
Dialog.create( "Save Image" );
Dialog.addChoice( "Format:", items, items[0] );
Dialog.show();
format = Dialog.getChoice();
saveAs( format );
run( "Close" );
//

HTH

What i mean is like in this picture

figure images/SaveAsImageSequence.png

I want to have posibility to choose what format to save.

Re: Analyse intensity in image of diffraction pattern

In reply to this post by sabau daniel

Apiot,

the greatest problem I see with analyzing intensities of the images is,
that they are over-exposed which results in unreliable intensity
measurements.

But there may be other problems if these images are from real
photographs. If so, you need to gamma-correct them for the non-linearity
of the photographic process. Gamma-correction requires knowledge about
the photographic material and the development process...

In case you are happy with an analysis of the position of the hexagonal
pattern, i.e. with a geometric analysis, both issues appear less important.

Please be more specific concerning the desired analyses.
