Returns True on success, False otherwise.

Note that after successful auto-orientation the internal orientation will be set to TopLeftOrientation. However this internal value is only written to TIFF files. For JPEG files, there is currently no support for resetting the EXIF orientation tag to TopLeft so the JPEG should be stripped or EXIF profile removed if present to prevent saved auto-oriented images from being incorrectly rotated a second time by follow-on viewers that understand the EXIF orientation tag.

## Description

The MagickCdlImage() method applies ("bakes in") the ASC-CDL which is a format for the exchange of basic primary color grading information between equipment and software from different manufacturers. The format defines the math for three functions: slope, offset and power. Each function uses a number for the red, green, and blue color channels for a total of nine numbers comprising a single color decision. A tenth number for chrominance (saturation) has been proposed but is not yet standardized.

The cdl argument string is comma delimited and is in the form (but without invervening spaces or line breaks):

redslope, redoffset, redpower : greenslope, greenoffset, greenpower : blueslope, blueoffset, bluepower : saturation

with the unity (no change) specification being:

"1.0,0.0,1.0:1.0,0.0,1.0:1.0,0.0,1.0:0.0"

See http://en.wikipedia.org/wiki/ASC_CDL for more information.

# MagickHaldClutImage

## Synopsis

    MagickPassFail MagickHaldClutImage( MagickWand *wand, const MagickWand *clut_wand );

## Description

The MagickHaldClutImage() method apply a color lookup table (Hald CLUT) to the image. The fundamental principle of the Hald CLUT algorithm is that application of an identity CLUT causes no change to the input image, but an identity CLUT image which has had its colors transformed in some way (e.g. in Adobe Photoshop) may be used to implement an identical transform on any other image.

The minimum CLUT level is 2, and the maximum depends on available memory (largest successfully tested is 24). A CLUT image is required to have equal width and height. A CLUT of level 8 is an image of dimension 512x512, a CLUT of level 16 is an image of dimension 4096x4096. Interpolation is used so extremely large CLUT images are not required.

GraphicsMagick provides an 'identity' coder which may be used to generate identity HLUTs. For example, reading from "identity:8" creates an identity CLUT of order 8.

The Hald CLUT algorithm has been developed by Eskil Steenberg as described at http://www.quelsolaar.com/technology/clut.html, and was adapted for GraphicsMagick by Clément Follet with support from Cédric Lejeune of Workflowers.

The format of the HaldClutImage method is:

    MagickPassFail MagickHaldClutImage( MagickWand *wand, const MagickWand *clut_wand );

# MagickSetCompressionQuality

## Synopsis

    unsigned int MagickSetCompressionQuality( MagickWand *wand, const unsigned long quality );

## Description

MagickSetCompressionQuality() sets the image quality factor, which determines compression options when saving the file.

For the JPEG and MPEG image formats, quality is 0 (lowest image quality and highest compression) to 100 (best quality but least effective compression). The default quality is 75. Use the -sampling-factor option to specify the factors for chroma downsampling. To use the same quality value as that found by the JPEG decoder, use the -define jpeg:preserve-settings flag.

For the MIFF image format, and the TIFF format while using ZIP compression, quality/10 is the zlib compres- sion level, which is 0 (worst but fastest compression) to 9 (best but slowest). It has no effect on the image appearance, since the compression is always lossless.

For the JPEG-2000 image format, quality is mapped using a non-linear equation to the compression ratio required by the Jasper library. This non-linear equation is intended to loosely approximate the quality provided by the JPEG v1 format. The default quality value 75 results in a request for 16:1 compression. The quality value 100 results in a request for non-lossy compres- sion.

For the MNG and PNG image formats, the quality value sets the zlib compression level (quality / 10) and filter-type (quality % 10). Compression levels range from 0 (fastest compression) to 100 (best but slowest). For compression level 0, the Huffman-only strategy is used, which is fastest but not necessarily the worst compression. If filter-type is 4 or less, the specified filter-type is used for all scanlines:

0. none
1. sub
2. up
3. average
4. Paeth

If filter-type is 5, adaptive filtering is used when quality is greater than 50 and the image does not have a color map, otherwise no filtering is used.

If filter-type is 6, adaptive filtering with minimum- sum-of-absolute-values is used.

Only if the output is MNG, if filter-type is 7, the LOCO color transformation and adaptive filtering with minimum-sum-of-absolute-values are used.

The default is quality is 75, which means nearly the best compression with adaptive filtering. The quality setting has no effect on the appearance of PNG and MNG images, since the compression is always lossless.

For further information, see the PNG specification.

When writing a JNG image with transparency, two quality values are required, one for the main image and one for the grayscale image that conveys the opacity channel. These are written as a single integer equal to the main image quality plus 1000 times the opacity quality. For example, if you want to use quality 75 for the main image and quality 90 to compress the opacity data, use -quality 90075.

For the PNM family of formats (PNM, PGM, and PPM) specify a quality factor of zero in order to obtain the ASCII variant of the format. Note that -compress none used to be used to trigger ASCII output but provided the opposite result of what was expected as compared with other formats.

    unsigned int MagickSetCompressionQuality( MagickWand *wand, const unsigned long quality );
