SIP provides image processing, pattern recognition, and computer vision routines for SciLab, a Matlab-like matrix-oriented programming environment. SIP is able to read/write images in almost 90 major formats, including JPEG, PNG, BMP, GIF, FITS, and TIFF. It includes routines for filtering, segmentation, edge detection, morphology, curvature, fractal dimension, distance transforms, multiscale skeletons, and more.
XPaint is an easy-to-use image editor which supports many standard and less standard paint procedures that demanding non-professional users would expect. It includes several advanced features like image processing algorithms, programmable C scripts, simultaneous editing of multiple images, and supports a wide variety of image formats.
mtPaint is a simple GTK+1/2 painting program designed for creating icons and pixel-based artwork. It can edit indexed palette or 24 bit RGB images and offers basic painting and palette manipulation tools. Its main file format is PNG, although it can also handle JPEG, GIF, TIFF, BMP, TGA, XPM, and XBM files.
Instant Picture Creator is a wrapper to produce images on demand for Web sites. It has filter management, and it's possible to add new filters. It can cache filtered images, works independently (no backend is needed), and is easy to integrate with existing Web sites. It includes two basic filters for resizing images and manipulating colour palettes. Currently it supports PNG, GIF, and JPEG.
Grafx2 is a bitmap paint program that allows you to draw in more than 60 video resolutions (from 320x200 to 1024x768, including most of the standard Amiga resolutions: 320x256, 320x512, 640x256, 640x512, and more, provided your video card knows how to handle them). Its layout is not very different from the famous Deluxe Paint or Brilliance, so it will be quite easy to handle it if you know at least one of these programs.
Raster3D is a set of powerful tools for generating high quality raster images of proteins or other molecules. The core program renders spheres, triangles, cylinders, and quadric surfaces with specular highlighting, Phong shading, and shadowing. It uses an efficient software Z-buffer algorithm that is independent of any graphics hardware.
F-Spot is a personal photo management application for the GNOME desktop. It simplifies digital photography by providing intuitive tools to help you share, touch-up, find, and organize your images. These tools include editing, color adjustments, tags, Photo CD creation, and exporting for upload.
Barcode Studio is designed to quickly create high-quality barcode images. It is commonly used for pre-press requirements, postal bar-coding, desktop publishing applications, mobile tagging, print shops, and general barcode purposes. It supports all linear barcodes (like Code39, 2of5, EAN, UPC, Code39, Code128, and EAN/UCC128), 2D barcodes (like PDF417, QR-Code, Aztec Code, DataMatrix ECC200, and MaxiCode), GS1 DataBar, and HIBC codes. Barcode data can be entered manually or imported from external data sources. Serial numbers are created automatically on demand. It has a built-in quality preview. Single as well as batch barcode creation is supported via the command line or the graphical user interface. Barcodes can be printed directly, copied to the clipboard, generated as image files (BMP, GIF, JPG, TIFF, or PNG) or exported as vector graphics (EPS, EMF, WMF , PDF, or PostScript). The created barcodes are useable immediately: Just insert the barcode graphics into your artwork, database, form, or any document.
