Free jpeg images software for mac

Jpeg impec 2.1 is a functional and easy-to-use script which manages several issues of JPEG image manipulation: EXIF header, icons, rotation, Colorsync. Its goal is to improve compatibility between OS X applications and other software, specifically from Canon.

The first goal is to insert back an EXIF header in an image from which it has been removed or modified by an image manipulation program. It is the case for all Quicktime applications under OS X (Image Capture, Preview, iPhoto). They modify coding of headers and suppress some proprietary fields (e.g. from Canon). Photos are thus deprived of some shooting informations. If transferred back in the camera or on a memory card they are sometimes unreadable.

This script also able to rotate the image in a lossless process. This is not the case with iPhoto. One can revert to the original of iPhoto and then rotate it with this script.

For a correct color rendering in OS X apps, itis necessary to include a Colorsync profile in the images. Otherwise they are too bland (for camera pictures). "Image Capture" can include a profile at download, but mess the exif header. It is better to do it latter with this script.

The Readme/Usage are in script comments, you can open it with standard Apple application "Script Editor". This "Manual" is also on the web site.

Requirements: Mac OS X 10.2 or later.

Image Tricks 2.4.2 is a freeware application for editing your photos and images using Mac OS X Core Image filters that transform your photos and apply advanced visual effects. This program also contains a powerful image generator for. It uses Mac OS X Core Image filters that transform pictures to unimaginable extent. Various mathematical algorithms let you generate unique images. Created artwork can be used as a background, web-design illustration, for print materials and more.

Try the Freeware version and if you like it you can purchase a license code to activate Pro version filters and generators for just $14.95.

ImageJ 1.43f is a program that is based on 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.
