>ChannelType
		
	
ChannelType is used as an
argument when doing color separations. Use 
ChannelType when
extracting a layer from an image. 
MatteChannel is useful for
extracting the opacity values from an image. Note that an image may
be represented in RGB, RGBA, CMYK, or CMYKA, pixel formats and a
channel may only be extracted if it is valid for the current pixel
format.

>ColorspaceType
		
	
The ColorspaceType enumeration is used to specify the colorspace
that quantization (color reduction and mapping) is done under or to
specify the colorspace when encoding an output image. Colorspaces are
ways of describing colors to fit the requirements of a particular
application (e.g. Television, offset printing, color monitors). 
Color reduction, by default, takes place in the 
RGBColorspace.
Empirical evidence suggests that distances in color spaces such as
YUVColorspace or YIQColorspace correspond to perceptual
color differences more closely han do distances in RGB space. These
color spaces may give better results when color reducing an image.
Refer to 
quantize for more details. 
When encoding an output image, the
colorspaces 
RGBColorspace, CMYKColorspace, and
GRAYColorspace may be specified. The CMYKColorspaceoption is only applicable when writing TIFF, JPEG, and Adobe
Photoshop bitmap (PSD) files.

>CompositeOperator
		
	
CompositeOperator is used to
select the image composition algorithm used to compose a 
composite
image
 with an image. By default, each of the composite
image pixels are replaced by the corresponding image tile pixel.
Specify 
CompositeOperator to select a different algorithm. 
CompositeOperator
	
		
			
Enumeration
		
		
			
Description
		
	
	
		
			
UndefinedCompositeOp
		
		
			
Unset value.
		
	
	
		
			
OverCompositeOp
		
		
			
The result is the union of the the two image shapes with the
			
composite image obscuring image in the region of
			overlap.
		
	
	
		
			
InCompositeOp
		
		
			
The result is a simply composite image cut by the shape
			of image. None of the image data of 
image is included in
			the result.
		
	
	
		
			
OutCompositeOp
		
		
			
The resulting image is composite image with the shape of
			
image cut out.
		
	
	
		
			
AtopCompositeOp
		
		
			
The result is the same shape as image image, with
			
composite image obscuring image there the image
			shapes overlap. Note that this differs from 
OverCompositeOp			because the portion of 
composite image outside of image's
			shape does not appear in the result.
		
	
	
		
			
XorCompositeOp
		
		
			
The result is the image data from both composite image			and 
image that is outside the overlap region. The overlap
			region will be blank.
		
	
	
		
			
PlusCompositeOp
		
		
			
The result is just the sum of the  image data. Output
			values are cropped to 255 (no overflow). This operation is
			independent of the matte channels.
		
	
	
		
			
MinusCompositeOp
		
		
			
The result of composite image - image, with
			overflow cropped to zero. The matte chanel is ignored (set to 255,
			full coverage).
		
	
	
		
			
AddCompositeOp
		
		
			
The result of composite image + image, with
			overflow wrapping around (mod 256).
		
	
	
		
			
SubtractCompositeOp
		
		
			
The result of composite image - image, with
			underflow wrapping around (mod 256). The add and subtract
			operators can be used to perform reverible transformations.
		
	
	
		
			
DifferenceCompositeOp
		
		
			
The result of abs(composite image - image). This
			is useful for comparing two very similar images.
		
	
	
		
			
MultiplyCompositeOp
		
		
			
 
		
	
	
		
			
BumpmapCompositeOp
		
		
			
The result image shaded by composite image.
		
	
	
		
			
CopyCompositeOp
		
		
			
The resulting image is image replaced with composite
			image
. Here the matte information is ignored.
		
	
	
		
			
CopyRedCompositeOp
		
		
			
The resulting image is the red layer in image replaced
			with the red layer in 
composite image. The other layers are
			copied untouched.
		
	
	
		
			
CopyGreenCompositeOp
		
		
			
The resulting image is the green layer in image replaced
			with the green layer in 
composite image. The other layers
			are copied untouched.
		
	
	
		
			
CopyBlueCompositeOp
		
		
			
The resulting image is the blue layer in image replaced
			with the blue layer in 
composite image. The other layers
			are copied untouched.
		
	
	
		
			
CopyOpacityCompositeOp
		
		
			
The resulting image is the matte layer in image replaced
			with the matte layer in 
composite image. The other layers
			are copied untouched. 
			
			
The image compositor requires a matte, or alpha channel in the
			image for some operations. This extra channel usually defines a
			mask which represents a sort of a cookie-cutter for the image.
			This is the case when matte is 255 (full coverage) for pixels
			inside the shape, zero outside, and between zero and 255 on the
			boundary.  For certain operations, if 
image does not
			have a matte channel, it is initialized with 0 for any pixel
			matching in color to pixel location (0,0), otherwise 255 (to work
			properly 
borderWidth must be 0).

>FilterTypes
		
	
FilterTypes is used to adjust
the filter algorithm used when resizing images. Different filters
experience varying degrees of success with various images and can
take sipngicantly different amounts of processing time.
ImageMagick uses the 
LanczosFilter by default since this
filter has been shown to provide the best results for most images in
a reasonable amount of time. Other filter types (e.g. 
TriangleFilter)
may execute much faster but may show artifacts when the image is
re-sized or around diagonal lines. The only way to be sure is to test
the filter with sample images.

>InterlaceType
		
	
InterlaceType specifies the ordering of the red, green, and
blue pixel information in the image. Interlacing is usually used to
make image information available to the user faster by taking
advantage of the space vs time tradeoff. For example, interlacing
allows images on the Web to be recognizable sooner and satellite
images to accumulate/render with image resolution increasing over
time. 
Use LineInterlace or
PlaneInterlace to create an interlaced GIF or progressive JPEG
image.

Rendering intent is a concept defined by http://www.color.org/ICC Spec ICC.1:1998-09, "File Format for Color Profiles".
ImageMagick uses 
RenderingIntent in order to support ICC
Color Profiles. 
From the specification: "Rendering
intent specifies the style of reproduction to be used during the
evaluation of this profile in a sequence of profiles. It applies
specifically to that profile in the sequence and not to the entire
sequence. Typically, the user or application will set the rendering
intent dynamically at runtime or embedding time." 
RenderingIntent
	
		
			
Enumeration
		
		
			
Description
		
	
	
		
			
UndefinedIntent
		
		
			
Unset value.
		
	
	
		
			
SaturationIntent
		
		
			
A rendering intent that specifies the saturation of the pixels
			in the image is preserved perhaps at the expense of accuracy in
			hue and lightness.
		
	
	
		
			
PerceptualIntent
		
		
			
A rendering intent that specifies the full gamut of the image
			is compressed or expanded to fill the gamut of the destination
			device. Gray balance is preserved but colorimetric accuracy might
			not be preserved.
		
	
	
		
			
AbsoluteIntent
		
		
			
Absolute colorimetric
		
	
	
		
			
RelativeIntent
		
		
			
Relative colorimetric
		
	
	
		
			
>ResolutionType
		
	
By default, ImageMagick defines
resolutions in pixels per inch. 
ResolutionType provides a
means to adjust this.

PixelsPerInchResolution
		
		
			
Density specifications are specified in units of pixels per
			inch (english units).
		
	
	
		
			
PixelsPerCentimeterResolution
		
		
			
Density specifications are specified in units of pixels per
			centimeter (metric units).
		
	
	
		
			
>StorageType
		
	
The StorageType enumerations are
used to specify the storage format of pixels in the source or
destination pixel array.

>StretchType
		
	
The StretchType enumerations are
used to specify the relative width of a font to the regular width for
the font family. If the width is not important, the 
AnyStretchenumeration may be specified for a wildcard match.

>StyleType
		
	
The StyleType enumerations are
used to specify the style (e.g. Italic) of a font. If the style is
not important, the 
AnyStyle enumeration may be specified for a
wildcard match.
