ImageMagick: Formats
Author: ImageMagick Studio LLC
Description: ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (P [cell cut: 1167 characters, first 1000 kept]

## Introducing Image Formats ImageMagick uses an ASCII string known as magick (e.g. `GIF`) to identify file formats, algorithms acting as formats, built-in patterns, and embedded profile types. Support for some of the formats are delegated to libraries or external programs. The Installation Guide describes where to find these distributions and any special configuration options required. To get a complete listing of which image formats are supported on your system, type

On some platforms, ImageMagick automatically processes these extensions: .gz for Zip compression, .Z for Unix compression, .bz2 for block compression, and .pgp for PGP encryption. For example, a PNM image called image.pnm.gz is automatically uncompressed. ## Supported Image Formats ImageMagick supports reading over 100 major file formats (not including sub-formats). The following table provides a summary of the supported image formats.

This file format is identical to that used by ImageMagick to represent images in memory and is read by mapping the file directly into memory. The MPC format is not portable and is not suitable as an archive format. It is suitable as an intermediate format for high-performance image processing. The MPC format requires two files to support one image. Image attributes are written to a file with the extension `.mpc`, whereas, image pixels are written to a file with the extension `.cache`.

PCL | W | HP Page Control Language | For output to HP laser printers.
PCX | RW | ZSoft IBM PC Paintbrush file |
PDB | RW | Palm Database ImageViewer Format |

Some PDF files, however, have a CropBox or TrimBox that is smaller than the MediaBox and may include white space, registration or cutting marks outside the CropBox or TrimBox. To force ImageMagick to use the CropBox or TrimBox rather than the MediaBox, use -define (e.g. `-define pdf:use-cropbox=true` or `-define pdf:use-trimbox=true`).

PNM | RW | Portable anymap | PNM is a family of formats supporting portable bitmaps (PBM) , graymaps (PGM), and pixmaps (PPM). There is no file format associated with pnm itself. If PNM is used as the output format specifier, then ImageMagick automatically selects the most appropriate format to represent the image. The default is to write the binary version of the formats. Use -compress none to write the ASCII version of the formats.
PPM | RW | Portable pixmap format (color) |
PS | RW | Adobe PostScript file | Requires Ghostscript to read. To force ImageMagick to respect the crop box, use -define (e.g. `-define ps:use-cropbox=true`).
PS2 | RW | Adobe Level II PostScript file | Requires Ghostscript to read.
PS3 | RW | Adobe Level III PostScript file | Requires Ghostscript to read.
PSD | RW | Adobe Photoshop bitmap file |

SVG | RW | Scalable Vector Graphics | Requires libxml2 and freetype-2. Note that SVG is a very complex specification so support is still not complete.
TGA | RW | Truevision Targa image | Also known as formats `ICB`, `VDA`, and `VST`.
TIFF | RW | Tagged Image File Format | Also known as `TIF`. Requires tiff-v3.6.1.tar.gz or later. Use -define to specify the rows per strip (e.g. `-define tiff:rows-per-strip=8`). To specify a signed format, use `-define quantum:format=signed`. To specify a single-precision floating-point format, use `-define quantum:format=floating-point`. Set the depth to 64 for a double-precision floating-point format. Use `-define quantum:polarity=min-is-black` or `-define quantum:polarity=min-is-white` toggle the photometric interpretation for a bilevel image.

TXT | RW | Raw text file |
UIL | W | X-Motif UIL table |
UYVY | RW | Interleaved YUV raw image | Use -size and -depth command line options to specify width and height. Use -sampling-factor to set the desired subsampling (e.g. -sampling-factor 4:2:2).
VICAR | RW | VICAR rasterfile format |

WMF | R | Windows Metafile | Requires libwmf. By default, renders WMF files using the dimensions specified by the metafile header. Use the -density option to adjust the output resolution, and thereby adjust the output size. The default output resolution is 72DPI so `-density 144` results in an image twice as large as the default. Use `-background color` to specify the WMF background color (default white) or `-texture filename` to specify a background texture image.
WPG | R | Word Perfect Graphics File |

## Built-in Images

ImageMagick includes a number of built-in (embedded) images which may be referenced as if they were an image file. The `magick:` format tag may be used via the syntax `magick:` name to request an embedded image (e.g. `magick:logo`). For backwards compatibility, the image specifications `GRANITE:`, `LOGO:`, `NETSCAPE:`, and `ROSE:` may also be used to request images with those names.
