A Word about Colorspaces • Supported Formats • Pseudo Formats • Built-in Images • Built-in Patterns • Embedded Profiles

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

    identify -list format

On some platforms, ImageMagick automagically 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 automagically uncompressed.

## A Word about Colorspaces

A majority of the image formats assume an sRGB colorspace (e.g. JPEG, PNG, etc.). A few support only linear RGB (e.g. EXR, DPX, CIN, HDR) or only linear GRAY (e.g. PGM). A few formats support CMYK. Then there is the occasional format that also supports LAB (that is CieLAB) (e.g. TIFF, PSD, JPG, JP2). To determine the colorspace of your image, use this command:

    -> identify -verbose image.jpg
    Image: image.jpg
    Format: JPEG (Joint Photographic Experts Group JFIF format)
    ...
    Colorspace: sRGB

OR use the appropriate percent escape

    -> convert image.jpg -print "%[colorspace]\n" null:
    sRGB

When processing an image, be aware of the colorspace. Many image processing algorithms assume a linear RGB colorspace. Although you may get satisfactory results processing in the sRGB colorspace, you may get improved results in linear RGB (essentially sRGB with the gamma function removed). For example,

    convert image.jpg -colorspace RGB -resize 50% -colorspace sRGB resize.jpg

As of IM 6.7.8-2 one can properly work in LAB colorspace whether or not Imagemagick is HDRI-enabled. Essentually the A and B channels are stored with a 50% gray bias, to allow it to handle the negatives required by the format.

    convert lab.tif -resize 50% resize.jpg

Again, it may not make sense for some image processing operators to work directly in LAB space, but ImageMagick permits it and generally returns reasonable results.

Prior to IM 6.7.8-2, the A and B channels has a discontinuity, making them non-linear. As such to process such images, you needed to first convert the colorspace some other linear colorspace, before apply your processing operator. Afterward you can transform back to the LAB colorspace. For example,

      convert lab.tif -colorspace RGB -resize 50% -colorspace Lab resize.jpg

JPEG | RW | Joint Photographic Experts Group JFIF format | Note, JPEG is a lossy compression. In addition, you cannot create black and white images with JPEG nor can you save transparency. Requires jpegsrc.v8c.tar.gz. You can set quality scaling for luminance and chrominance separately (e.g. -quality 90,70). You can optionally define the DCT method, for example to specify the float method, use -define jpeg:dct-method=float. By default we compute optimal Huffman coding tables. Specify -define jpeg:optimize-coding=false to use the default Huffman tables. Two other options include -define jpeg:block-smoothing and -define jpeg:fancy-upsampling. Set the sampling factor with -define jpeg:sampling-factor. You can size the image with `jpeg:size`, for example -define jpeg:size=128x128. To restrict the maximum file size, use `jpeg:extent`, for example -define jpeg:extent=400KB. To define one or more custom quantization tables, use -define jpeg:q-table=filename. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).

MONO | RW | Bi-level bitmap in least-significant-byte first order |
MNG | RW | Multiple-image Network Graphics | A PNG-like Image Format Supporting Multiple Images, Animation and Transparent JPEG. Requires libpng-1.0.11 or later, libpng-1.2.5 or later recommended. An interframe delay of 0 generates one frame with each additional layer composited on top. For motion, be sure to specify a non-zero delay.
M2V | RW | Motion Picture Experts Group file interchange format (version 2) | Requires ffmpeg.
MPEG | RW | Motion Picture Experts Group file interchange format (version 1) | Requires ffmpeg.
MPC | RW | Magick Persistent Cache image file format | The most efficient data processing pattern is a write-once, read-many-times pattern. The image is generated or copied from source, then various analyses are performed on the image pixels over time. MPC supports this pattern. MPC is the native in-memory ImageMagick uncompressed file format. 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`.
MPR | RW | Magick Persistent Registry | This format permits you to write to and read images from memory. The image persists until the program exits. For example, let's use the MPR to create a checkerboard:
    convert \( -size 15x15 canvas:black canvas:white -append \) \
      \( +clone -flip \) +append -write mpr:checkers +delete \
      -size 240x240 tile:mpr:checkers board.png

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`). Use -density to improve the appearance of your PDF rendering (e.g. -density 300x300). Use -alpha remove to remove transparency. To specify direct conversion from Postscript to PDF, use `-define delegate:bimodel=true`. Use `-define pdf:fit-page=true` to scale to the page size. To immediately stop processing upon an error, set `-define pdf:stop-on-error` to `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 automagically 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 eps:use-cropbox=true`).

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 define the tile geometry, use for example, `-define tiff:tile-geometry=128x128`. 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. Specify the extra samples as associated or unassociated alpha with, for example, `-define tiff:alpha=unassociated`. Set the fill order with `-define tiff:fill-order=msb|lsb`. Set the TIFF endianess with `-define tiff:endian=msb|lsb`. Use `-define tiff:exif-properties=false` to skip reading the EXIF properties. You can set a number of TIFF software attributes including document name, host computer, artist, timestamp, make, model, software, and copyright. For example, -set tiff:software "My Company". If you want to ignore certain TIFF tags, use this option: `-define tiff:ignore-tags=comma-separated-list-of-tag-IDs`.

XC | R | Canvas image of specified color | An backward compatible alias for the '`canvas:`' psuedo-file format, used to create a solid color canvas image.

## 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.

Tag | Mode | Description | Notes
--- | --- | --- | ---

## Built-in Patterns

ImageMagick includes a number of built-in (embedded) patterns which may be referenced as if they were an image file. The `pattern:` format tag may be used via the syntax `pattern:`name to request an embedded pattern (e.g. `pattern:checkerboard`). The pattern size is controlled with the -size command line option.
