• 1.51q 18 September 2017
  • Plot enhancements, thanks to Michael Schmid:
    • Plots saved as tiff or zip include the data, so the plot range can be modified (zooming, etc.) and the data can be listed after loading the plot from a file.
    • Changing the axis or label font size of a plot keeps the image size constant and modifies the plot frame size (previously, the plot frame size was constant).
    • Slightly more space for numbers at the left, enough for scientific notation. ImageJ switches to a smaller font if more significant digits are required.
    • Added Plot.getFrameBounds(x, y, width, height) macro function.
    • The default font for plots is now Arial, not Helvetica (Arial is available on more platforms).
    • When opening a plot on a computer where a given font is not available, try to replace fonts by similar ones. This should make the appearance on different platforms more similar.
    • The ImageProcessor getStringWidth() and getStringBounds() methods use the more accurate GlyphVector class.

  • Fixed a bug that caused a null pointer exception when clicking on a 16-bit or 32-bit image with the dropper tool.

  Version 0.95, 19-November-98

  • The Plug-Ins/"Show Display Speeds" command was updated to include results for JDK 1.2. The results show that the crucial drawImage method is up to 22 times slower compared to JDK 1.1.7. To encourage Sun to fix this problem, vote for bug 4185726 ("JDK 1.2rc1 drawImage very slow (50% slower) compared to JDK 1.1.7") on the Bug Parade. ImageJ is not going to run well under JDK 1.2 until this problem is fixed.
  • Added the "Waves" plug-in that continuously applies a sine wave to the x-coordinates of an image. Click on the image or press the escape key to stop. This plug-in is useful as a benchmark (it displays the frame rate), as a way to demonstrate ImageJ's multi-tasking ability, and as an example of a plug-in that processes both 8-bit and RGB images.
  • Added a "Transformations" sub-menu to the Image menu and moved the "Flip Vertical" and "Flip Horizontal" commands into it.
  • Added the "Rescale" command to the Transformations sub-menu for scaling an image to a specified width and height.
  • Added commands to rotate an image 90 degrees left or right to the Transformations sub-menu.
  • The "Show Benchmark Times" and "Show Display Speeds" commands no longer require that an image be open.
  • Stack animation is now much faster.
  • The slice selection scroll bar in stack windows now works more reliably.
  • The Invert, Smooth, Find Edges, Add Noise, Despeckle and Threshold commands now operate on all the slices of a stack.
  • The Reduce Noise command, a median filter, was renamed Despeckle.
  • Added a public "running" flag to the ImageWindow class. Plug-ins can use this flag to terminate themselves when the user clicks on the image or presses the escape key. See /ij/plugin/filter/Waves.java for an example.
  • Improved the interface used by plug-in filters. Filters must now implement the PlugInFilter interface and be in the the ij.plugin.filter package. They must also provide a setup method that ImageJ will call to determine the filters capabilities. See ij/plugin/filter/PlugInFilter.java for more information and ij/plugin/filter/Invert.java for an example.
  • Added the GenericDialog class that plug-in can use to acquire multipler numeric parameters. See /ij/plugin/filter/Resizer.java for an example of how to use this new class.
  • The lock method in ImagePlus beeps and displays a status bar message if the image is already locked.
  • The reserve and unreserve methods in the ImagePlus class were renamed lock and unlock.

  Version 0.94, 21-October-98

  • The File/Acquire/Raw command no longer generates extra blank slices at the end of the stack when more than the actual number of images is specified.
  • Added a "Gap Between Images" field to the File/Acquire/Raw dialog box. This allows import of multi-image files with gaps between the images (e.g. uncompressed 8-bit AVI movies with a 4104 byte header and a gap of 8). Set the gap to (n-1)*width*height*2*real-gap to read every nth frame in a movie.
  • Changes to RGB images made using the Image/Adjust Contrast command are now be limited to the interior of non-rectangular selections.
  • The Process/Math command now works correctly with non-rectangular selections.
  • The Open... command now opens BMP files with names ending in ".bmp".
  • Added a command to the Save As sub-menu for saving images in JPEG format. It uses the JPEG encoder from http://www.obrador.com. Use the Edit/JPEG Quality command to specify the compression level.
  • The wand tool now more reliably traces areas defined by a one pixel wide boundary line.

  Version 0.93, 7-October-98

  • Added a constructor to the GifEncoder class for saving 8-bit AWT images.
  • Added the Edit/Fonts command for specifying the font, font size and font style. For a shortcut, double-click on the Text tool in the tool bar.
  • Double-clicking in the tool bar on any of the three line selection tools now brings up the set line width dialog.
  • Added a "Colors..." command to the Image menu. It downloads and displays an image that can be used, in conjunction with the dropper tool, to set the drawing color. Note that holding down the alt (option) key temporarily switches to the dropper tool.
  • Moved the Draw Arrow command from the PlugIns menu to the Edit menu.
  • Moved the Draw Arrow command from the PlugIns menu to the Edit menu.
  • Moved the Adjust Contrast command from the PlugIns menu to the Image menu.

  Version 0.89, 16-September-98

  • Added a text (annotation) tool. Use it to create a text rectangle, type some text, then use Edit/Draw to add the text to the Image. To draw the text on a white background, use Edit/Clear prior to Edit/Draw. To change the font size, use Edit/Font Size or double-click on the text tool. There is currently no way to select a different font or style. Text rectangles are currently limited to one line.
  • Added a Draw command to the pop-up menu. To use this menu, right-click on an image (option-click on the Mac).
  • Fixed a bug that sometimes caused operations on non-rectangular regions in stacks to fail.
  • Fixed a bug that could result in multiple checked items in the Type sub-menu after an attempt to do an unsupported conversion.

  • Updated "Plug-Ins/Show Benchmark Times" to include results for Apple's MRJ 2.1ea2.
  • Fixed a bug that could cause images to become permanently locked when memory was low.
  • Fixed a minor bug in the Image/Scale command. To see the bug in action, use Acquire/URL to load the image http://rsbweb.nih.gov/~wayne/ij/images/dots.gif, and then use Image/Scale to scale it by 2.
  • When switching slices (channels) in RGBA or HSB stacks, the slice name ("red", "green", "blue", "hue", "saturation" or "brightness") is now displayed in the status bar.
  • Removed the Image/Channel sub-menu.

  Version 0.87, 20-August-98

  • Fixed several problems that caused Edit/Draw and Edit/Fill to use incorrect colors with in 8-bit images.
  • Hold down the alt (option) key to temporarily switch to the hand (panning) tool.
  • Alt-click (option-click) on an image with any tool except the magnifying glass to "pick up" a new drawing color. This is a shortcut for switching to the dropper tool, clicking on the image to select a drawing color, and then switching back to the original tool.
  • The Plug-Ins menu has a new command that tests to see how fast the JVM can draw images to the screen.

  Version 0.86, 2-July-98

  • The Draw command works again.
  • Fixed a null pointer exception error (introduced in 0.83) that followed the "There are no Images open." dialog.

  Version 0.84, 19-June-98

  • New stand alone versions for Mac OS8 and Windows are available. The Mac version include source code and a Metrowerks CodeWarrior project file. The Windows version includes the source and Java Runtime Environment (JRE) 1.1.6. There is also a much smaller ZIP file containing the class files and source but not the JRE.

  Version 0.82, 5-June-98

  • "Adjust Contrast" now changes the brightness and contrast of 8-bit images by updating the image's look-up table rather than its pixel values. This is particularly nice when working with stacks since brightness and contrast changes apply to all the slices in the stack.
  • Added two sample stacks to the Open menu. "MRI Stack" is a 3D MRI head scan consisting of 27 186x226 axial slices and "Scala Media Stack" is a 36 frame 3D movie of the scala media volume within the cochlea of the moustached bat.
  • Three of the larger sample images (Boats, Bridge and Gel) now download more reliably as a result of being converted from gifs to tiffs.
  • The FileOpener class now supports URLs and can open 8-bit stacks.
  • Acquire/Raw can now import multi-image 8-bit files.

  • Changed the name of the URL plug-in to URLOpener.
  • The Acquire/Raw and Math commands now "remember" the popup menu selection.
  • Added a 16-bit image of the M51 galaxy to the Open submenu. As an exercise, try using Adjust Contrast to bring out detail in the galaxy. One useful trick is to select a region of interest and click on the "Auto" button.
