Free file formats for images software for linux

libAfterImage is a small, fast, and powerful library for high-quality image manipulation.
libAfterImage is a generic image manipulation library. It was initially implemented to address AfterStep Window Managers needs for image handling, but it evolved into extremely powerfull and flexible software, suitable for virtually any project that has needs for loading, manipulating, displaying images, as well as writing images in files.
Most of the popular image formats are supported using standard libraries, with XCF, XPM, PPM/PNM, BMP, ICO, TGA and GIF being supported internally.
PNG, JPEG and TIFF formats are supported via standard libraries.
For convinience, source for libJPEG and libPNG is supplied with libAfterImage.
Powerfull text rendering capabilities included, providing support for TrueType fonts using FreeType library, and antialiasing of standard fonts from X window system.
Primary design goals of libAfterImage are memory efficiency and superior image quality.
Extensive documentation, examples, and XML image scripting tool ascompose, are included with the library.
libAfterImage allows output of the image on any of the X11 display, MS Windows DIB, or standard output, which is suitable for web servers.
Enhancements:
- New features include image slicing, better support for 32-bit visuals, and proper Gaussian blur with radii up to 128.

e2fsimage allows you to create ext2 filesystem images, mostly used on Linux systems, by copying an entire directory structure into an ext2 formatted image without needing root permissions.
Without this tool you need to loopback-mount an existing filesystem image and copy all files there as root.
This application is usually used by people creating rescue disks, initrds, bootable floppys or CDs or the more. Especially on build hosts where they do not have root permissions and the ptrace() bug is already fixed.
Enhancements:
- support for user ids in .UIDGID file and usernames resolved by passwd file
- free uiddb structure after use
- manpage updated

Partition Image application is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file.
The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example); partitions can be saved across the network since version 0.6.0.
Partition Image will only copy data from the used portions of the partition. For speed and efficiency, free blocks are not written to the image file.
This is unlike the dd command, which also copies empty blocks. Partition Image also works for large, very full partitions. For example, a full 1 GB partition can be compressed with gzip down to 400MB.
This is very useful to save partitions to an image in some cases:
- First you can restore your linux partition if there is a problem (virus, file system errors, manipulation error) . When you have a problem, you just have to restore the partition, and after 10 minutes, you have the original partition. You can write the image to a CD-R if you dont want the image to use hard-disk space.
- This utility can be used to install many identical PCs. For example, if you buy 50 PCs, with the same hardware, and you want to install the same linux systems on all 50 PCs, you will save a lot of time. Indeed, you just have to install on the first PC and create an image from it. For the 49 others, you can use the image file and Partition Images restore function.

ImageServer is a software for maintaining archives of images. Theres much software available to manually view, categorize and search images. ImageServer was designed to solve a different problem:
Imagine being a photographer or photo agency: You have a lot of images in many formats, all stored in a directory structure - your archive.
This creates at least two problems:
- The archive may contain different images with the same name. What do you do when a customer orders "flowers.tif" and this name exists in twenty different subfolders in your archive?
- The customer doesnt need your original 22megapixel 16-bit tiff file for his powerpoint presentation or layouting, he wants a small jpeg instead.
The first problem can be managed by assigning unique names to images every time an image is put into the archive.
The second problem is a little more difficult. Youll have to convert the requested images to smaller JPEGs. After doing that for too many times, you start caching the small JPEGs so you wont have to convert again for the next customer asking for that image. But then, you edit the original image and forget to update the JPEGs. Furthermore, its not enough to keep these resized jpegs for presentations, your customers graphics department also wants correctly downsampled eps images for layouting advertisements in QuarkXPress. So you start having two slaveArchives - one with JPEG and one with EPS images - and spend half of your day trying to synchronize the three.
ImageServer solves both problems automatically. It is a program with a nice GUI, configured to watch your masterArchive. As soon as images are put into any subfolder, theyll be assigned unique names if necessary. Afterwards, each image is read, and for each defined slaveArchive, a preview is created and saved. The same happens when an image in the masterArchive is altered. All this works completely automatically, theres nothing youll have to do; the GUI is just for being able to watch whats happening.
Main features:
- Input file checking: as soon as an image is put into the archive, ImageServer checks the extension to see whether it really is an image. If not, it is put into a specified folder outside of the archive.
- If configured to do so, an image without a suiting name is assigned a new name which is constructed of both the subfolders it resides in and a unique-per-subfolder serial number of arbitrary length.
- When detecting a change in the masterArchive, ImageServer can play a sound.
- When starting to convert an image, ImageServer can play a sound.
- ImageServer can remember the names it has already assigned to images in the past. This way, names assigned to an image A will never be assigned to another image B after A has been deleted.
- Any number of slaveArchives can be defined, and they can be in any location.
- Each defined slaveArchive can have completely different settings for the images that will populate it. Resizing or resampling? RGB or CMYK? Jpeg, EPS, PNG or TIFF?
- You can choose whether each slaveArchive should inherit the exact same directory structure from the masterArchive or whether the slaveArchives images should all be put into the same folder.
- In case dazuko missed something, you can tell imageserver to manually look into a folder. It can then either process all images in that folder or only those where slaveArchive-images are missing.

JImage-Analyst is a JAVA based library for extracting meta information from various image file formats.

File file = new File("test.gif");
JImageAnalyst analyst = JImageAnalystFactory.getDefaultInstance();
ImageInfo imageInfo = analyst.analyze(file);
System.out.println("Format: " + imageInfo.getFormat());
System.out.println("MIME-Type: " + imageInfo.getMimeType());
System.out.println("Width: " + imageInfo.getWidth());
System.out.println("Height: " + imageInfo.getHeight());
System.out.println("BitsPerPixel: " + imageInfo.getBitsPerPixel());
// ... more information is available in imageInfo ...
