PdfRipImage is a program to automatically extract images from PDF documents and convert them to a format of your choice (such as JPEG or TIFF). It runs on UNIX-like platforms and requires utilities from netpbm and xpdf.
Phatch handles all popular image formats and can duplicate (sub)folder hierarchies. It can batch resize, rotate, apply perspective, shadows, rounded corners, ... and more in minutes instead of hours or days if you do it manually. Phatch allows you to use EXIF and IPTC tags for renaming and data stamping. Phatch also supports a console version to batch photos on web servers. Read more
Photini is an easy to use digital photograph metadata (EXIF, IPTC, XMP) editing application. Read more
pict2png is a utility for converting files in the Macintosh PICT image format to the PNG image format.
pixel2svg converts pixel art to SVG - pixel by pixel.
png2html takes a PNG image and transforms it into a Web page with the use of a text file.
png2linuxlogo is a command-line utility to convert a PNG image of appropriate size (80x80 pixels) and type (palette, 223 or fewer colors) to the "full-color" logo format used by the Linux kernel. That is, its output is a text file that is suitable for replacing include/asm/linux_logo.h in standard Linux kernel distributions (versions 2.0 and up, probably).
Pngcrush is an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX or LINUX commandline. Its main purpose is to reduce the size of the PNG IDAT datastream by trying various compression levels an PNG filter methods. It also can be used to remove unwanted ancillary chunks, or to add certain chunks including gAMA, tRNS, iCCP, and textual chunks. Read more
Contains pnmtopng and pngtopnm, utilities for use with the rest of the PBMplus/NetPBM suit.
ppmtoansi converts an image in .ppm format to text with ANSI coloring. Uses could include viewing of picture attachments in the mutt e-mail client.
pstoedit translates PostScript and PDF graphics into other vector formats. Read more
Python-GPSBabel is a Python wrapper around GPSBabel. It is a complete interface for Python, allowing easy mechanisms for the developer to control GPSBabel from within a Python application.
Ra-vec is a vectorising programme designed to rapidly prototype 3D worlds from line drawings, in particular architect's plans. Ra-vec creates a 2D vector file, describing the features in the plan. This can then be imported to AC3D and either extruded to produce a quick 3D environment, or used as the basis for a more detailed model.
Rawstudio can read and convert RAW-images from many different cameras, including Nikon and Canon. It reads all dcraw supported formats, and has a realtime histogram. Read more
RawTherapee (The Experimental Raw Photo Editor) is a cross-platform raw image processing application. Read more
S3TC-BOXEN is a small tool that s3tc-compresses your bmp/jpg/png textures.
sam2p is a UNIX command line utility written in ANSI C++ that converts many raster (bitmap) image formats into Adobe PostScript or PDF files. The images are not vectorized. sam2p gives full control to the user to specify standards-compliance, compression, and bit depths.
shape2ge is a set of two applications for converting ESRI shapefiles into Google Earth KML files. It consists of a batchable converter engine that reads conversion options from an XML config file generated by the front-end or other methods. The CLI-based front-end allows you set scales and offsets (from shapefile coords to earth coords), and also to assign different display styles to different feature types.
Tex2im is a simple tool that converts LaTeX formulas into high resolution pixmap graphics for inclusion in text processors or presentations.
tiff2png provides direct TIFF-to-PNG conversion capabilities in a single package. The primary goal was to preserve alpha (transparency) information, but scaling information is also preserved, and the compression setting can be set by the user. This is a command-line program with batch capabilities (e.g., ``tiff2png *.tiff'').
Tiler is a really quick little GUI application for Win/Lin/* that can tile an image into a big image with customizable borders and such.
tozwgc is a small program that uses convert (from ImageMagick) to convert a picture from any format to a message that can be sent using Zephyr.
Tumble is a utility to construct PDF files from one or more image files. Supported input image file formats are JPEG, and black and white TIFF files (single- or multi-page). Black and white images will be encoded in the PDF output using lossless Group 4 fax compression (ITU-T recommendation T.6). This provides a very good compression ratio for text and line art. JPEG images will be preserved with the original coding.
uml2svg is an XSLT-based tool for converting XMI-compliant UML diagrams into SVG.
UniConvertor is a universal vector graphics translator, which uses the sK1 engine to convert one format to another. There are import filters for CorelDraw (CDR and CMX), Adobe Illustrator (AI), Scalable Vector Graphics (SVG), and some other formats, and export filters for AI, SVG, WMF, and sK1's own format.
vec2web is a tool to convert vector drawings (DXF) to graphics which can be used on the Web (PNG).
