The following table provides a summary of ImageMagick supports reading over 100 major file formats (not Essentially the A andī channels are stored with a 50% gray bias, to allow it to handle theĪgain, it may not make sense for some image processing operators to workĭirectly in LAB space, but ImageMagick permits it and generally returns Magick image.jpg -colorspace RGB -resize 50% -colorspace sRGB resize.jpgĪs of IM 6.7.8-2 one can properly work in LAB colorspace whether or not Results in linear RGB (essentially sRGB with the gamma function removed). Satisfactory results processing in the sRGB colorspace, you may get improved Processing algorithms assume a linear RGB colorspace. When processing an image, be aware of the colorspace. To determine the colorspace of your image, useįormat: JPEG (Joint Photographic Experts Group JFIF format) Then there is the occasional format that also supports LAB (that is CieLAB) EXR,ĭPX, CIN, HDR) or only linear GRAY (e.g. A Word about ColorspacesĪ majority of the image formats assume an sRGBĬolorspace (e.g. For example, a PNM image called is automagically uncompressed. On some platforms, ImageMagick automagically processes these extensions. To get a complete listing of which image formats are supported on your system, type The Installation Guide describes where to find these distributions and any special configuration options required. Support for some of the formats are delegated to libraries or external programs. GIF) to identify file formats, algorithms acting as formats, built-in patterns, and embedded profile types. ImageMagick uses an ASCII string known as magick (e.g.
