Area Puzzles 1.2 is designed to be an interesting puzzle in which students are shown a ten by ten grid "sprinkled" with numbers. Students must fill the grid with colored rectangles so that the area of each rectangle matches the "sprinkle" number inside of it.

GrandPerspective 1.1.0 is specifically designed for Mac OS X to graphically show the disk usage within a file system. It can help you to manage your disk, as you can easily spot which files and folders take up the most space.

It uses a so called tree map for visualization. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary.

Major Features:

1. Disk usage visualisation by way of tree maps
2. Configurable display of views:
   • Choice of color mapping schemes
   • Choice of color palettes
   • Configurable mapping by file type
   • Optionally view package contents
   • Optionally view the entire volume

   • Traverse up and down the folder hierarchy
   • Select files and folders in the view
4. Reveal files and folders in the Finder
5. Delete files and folders from the view
6. User-configurable rules on files and folders:
   • Construct rules using tests on an item's: name, path, size, file type, hard-link status, and package status
   • Use these rules to:
   • Mask files in the view
   • Filter files from the view
   • Exclude files and folders when scanning a disk
7. Multiple view support:
   • Re-scan a view to compare results before and after clean-up
   • Twin or duplicate a view for different displays of the same data

DrawIt supports over 50, stackable, nondestructive Core Image filters. Individual properties can be freely edited, regardless how many filters have been applied. Filter properties can be readjusted and/or reordered at any time; the original object is never discarded.

Area/Volume Converter 1.0 is a professional and smart application which is designed to find the area of squares, rectangles, parallelograms, triangles, circles, cubes, rectangular prisims, triangular prisims, and spheres. It can also find the diameter and circumference of circles.

ImageJ 1.43j can be considered to be a high-quality and handy public domain Java image processing program which is inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations. It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles.

It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering. It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory. Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.

Major Features:

1. Runs Everywhere: ImageJ is written in Java, which allows it to run on Linux, Mac OS X and Windows, in both 32-bit and 64-bit modes.
2. Open Source: ImageJ and its Java source code are freely available and in the public domain. No license is required.
3. User Community: ImageJ has a large and knowledgeable worldwide user community. More than 1700 users and developers subscribe to the ImageJ mailing list.
4. Macros: Automate tasks and create custom tools using macros. Generate macro code using the command recorder and debug it using the macro debugger. More than 300 macros are available on the ImageJ Web site.
5. Plugins: Extend ImageJ by developing plugins using ImageJ's built in text editor and Java compiler. More than 500 plugins are available.
6. Toolkit: Use ImageJ as a image processing toolkit (class library) to develop applets, servlets or applications.
7. Speed: ImageJ is the world's fastest pure Java image processing program. It can filter a 2048x2048 image in 0.1 seconds (*). That's 40 million pixels per second!
8. Data Types: 8-bit grayscale or indexed color, 16-bit unsigned integer, 32-bit floating-point and RGB color.
9. File Formats: Open and save all supported data types as TIFF (uncompressed) or as raw data. Open and save GIF, JPEG, BMP, PNG, PGM, FITS and ASCII. Open DICOM. Open TIFFs, GIFs, JPEGs, DICOMs and raw data using a URL. Open and save many other formats using plugins.
10. Image display: Tools are provided for zooming (1:32 to 32:1) and scrolling images. All analysis and processing functions work at any magnification factor.
11. Selections: Create rectangular, elliptical or irregular area selections. Create line and point selections. Edit selectoins and automatically create them using the wand tool. Draw, fill, clear, filter or measure selections. Save selections and transer them to other images.
12. Image Enhancement: Supports smoothing, sharpening, edge detection, median filtering and thresholding on both 8-bit grayscale and RGB color images. Interactively adjust brightness and contrast of 8, 16 and 32-bit images.
13. Geometric Operations: Crop, scale, resize and rotate. Flip vertically or horizontally.
14. Analysis: Measure area, mean, standard deviation, min and max of selection or entire image. Measure lengths and angles. Use real world measurement units such as millimeters. Calibrate using density standards. Generate histograms and profile plots.
15. Editing: Cut, copy or paste images or selections. Paste using AND, OR, XOR or "Blend" modes. Add text, arrows, rectangles, ellipses or polygons to images.
16. Color Processing: Split a 32-bit color image into RGB or HSV components. Merge 8-bit components into a color image. Convert an RGB image to 8-bit indexed color. Apply pseudo-color palettes to grayscale images.
17. Stacks: Display a "stack" of related images in a single window. Process an entire stack using a single command. Open a folder of images as a stack. Save stacks as multi-image TIFF files.

Turn Clip is an iMovie plug-in that rotates your clip exactly 90, 180 or 270 degrees.
Since DV clips are not square, parts of the clip will be lost when rotating 90 or 270 degrees, and the clip will show bands of a (user defined) color left and right of the formerly narrow parts.
Main features:
- background color:
- this color control lets you select the color that will be revealed when parts of the rotated clip fall off-screen, or that are cropped
- outside:
- if this box is checked, the clip is cropped to the contents of the active area. everything that is not originally inside the active area will be set to the background color.
- clip:
- the turned image can be clipped to the active area box. it will be clipped when this box is checked.
- active area:
- the area inside this rectangle will be turned. everything outside will be cropped, and assumes the chosen background color (see above).
- select all:
- pressing this button will select the whole clip as active area.
- movie slider, forward, backward:
- use this slider to move through the currently selected clip.
- opacity:
- this slider controls how much of the original footage will shine through.
- turn
- this slider controls how much to turn the clip. it recognizes four settings: 0, 90, 180, and 270 degrees.
