createContactSheetGraphic(image, axis, device = c("internal", "png"), colourScale = 1,
add = FALSE, file = NULL, zoomFactor = 1, filter = "Mitchell",
windowLimits = NULL, clearance = NULL, nColumns = NULL)
参数----------Arguments----------
参数：images
A list of MriImage objects.
的名单MriImage对象。
参数：image
A single MriImage object.
一个单一的MriImage对象。
参数：modes
A character vector of the same length as images, each element being "slice" or "projection" (or abbreviations), indicating which type of visualisation should be applied to each image.
images，每个元素是"slice"或"projection"（或缩写），指示哪种类型的可视化，应适用于每个图像的长度相同的字符的矢量。
参数：colourScale, colourScales
A single colour scale definition, or a list in the plural case. See Details.
的单颜色标度的定义，或在多个情况下的列表。查看详细信息。
参数：axis, axes
A vector of axes along which slice/projection images should be created. 1 is left-right, 2 is anterior-posterior, 3 is superior-inferior.
轴的矢量沿着这片/投影图像应建立。图1是图2是左 - 右，前 - 后，图3是优越的劣势。
参数：x, y, z
Integer vectors, each of length 1. Exactly one of these must be specified to indicate the plane of interest.
整数向量，每一个的长度为1。必须恰好是其中之一必须指定，表示飞机的兴趣。
参数：sliceLoc
Like x, y and z, except that a point in 3 dimensions is specified. Must not be NA for each axis requested.
喜欢x，y和z，除了在3维的点被指定。一定不能NA每个axis要求。
参数：device
Either "internal" for display on the default graphics device, or "png" for creating PNG format image file(s). Abbreviations are fine.
是"internal"显卡的默认设备上显示，或"png"创建PNG格式的图像文件（S）。缩略语的罚款。
参数：alphaImages
A list of MriImage objects to be used as transparency masks. Must be the same length as images if not NULL. NULL values in the list indicate no mask.
列表：MriImage对象被用来作为透明度口罩。必须是相同的长度，images如果NULL的。 NULL列表中的值表示没有面具。
参数：prefix, file
A file name or prefix (to which "axial", "coronal" or "sagittal" will be added) to be used when device is "png".
文件名或前缀（"axial"，"coronal"或"sagittal"将被添加），用于device是"png"。
参数：zoomFactor
Factor by which to enlarge the image. Applies only when device is "png".
将图像放大的因素。仅适用于device是"png"。
参数：filter
Interpolation filter to be used by ImageMagick.
ImageMagick的要使用的插值滤波器。
参数：windowLimits
Numeric vector of length 2 giving the limits of the colour scale, or NULL for limits matching the range of the image data. Passed as the zlim argument to image.
长度为2的数值向量给色阶的极限，或NULL匹配的范围内的图像数据的限制。作为zlimimage参数通过。
参数：clearance
Number of voxels' clearance to leave around each slice image in the contact sheet. Passed to newMriImageByTrimming.
体素“通关离开的联系表中的每个切片图像的数目。传递到newMriImageByTrimming。
参数：nColumns
Number of slices per row in the contact sheet grid. If NULL, the function will aim for a square grid.
接触片网格中每行的片数。如果NULL，该函数将目标一个正方形网格。
参数：add
Overlay the graphic on a previous one. Used only when device is "internal".
一前一叠加的图形。仅用于时device是"internal"。

详细信息----------Details----------
These functions create 2D visualisations of 3D images by slicing or maximum intensity projection.
这些函数创建的二维可视化的三维图像切片或最大强度投影。
Colour scales can be specified in any of three ways. Firstly, by a single number, representing a predefined colour scale. Currently valid values are 1 (greyscale, black background), 2 (red to yellow heat scale, red background), 3 (blue to red rainbow scale, blue background) and 4 (blue to white to red diverging scale, white background). Secondly, a single colour name can be given (see colours); in this case the background will be black. This is useful for binary images. Thirdly and most flexibly, a list with two named elements can be given: colours, a vector of colours representing the colour scale, perhaps created using rgb; and background, a single colour representing the background.
三种方式中，可以指定颜色尺度。首先，由一个单一的数字，代表一个预定义的颜色规模。目前有效的值是1（灰度，黑色背景），2（红色，黄热规模，红色背景），3（蓝色，红色的彩虹规模，蓝色背景）和4（蓝色，白色，红色，不同的规模，白色背景）。其次，单一颜色的名称，可以（colours），在这种情况下，背景是黑色的。为二进制图像，这是非常有用的。第三，也是最灵活的是，有两个命名的元素的列表可以colours的代表色标颜色，矢量，也许使用rgb和background，一个单一的颜色，代表的背景。
NB: When the device option is set to "png", ImageMagick is required by these functions.
注意：，当device选项设置为"png"的，ImageMagick是需要这些功能。
值----------Value----------
These functions are called for their side effects.
这些函数被称为他们的副作用。
