Options useful for Image objects include ColorSpace, Interleaving, ImageResolution, ImageSize, and Magnification.Ĭite this as: Wolfram Research (2008), Image, Wolfram Language function, (updated 2019).

The number of channels the image contains may be obtained using the function ImageChannels.

Image itself can be used to convert between image types, and ImageAdjust can be used to bring all values of a real-valued image into the range 0 to 1. ImageType gives a label representing the number type used internally to represent each pixel of an image. ImageDimensions gives the pixel dimensions of the raster associated with an Image object. The array of pixel values in an image may be obtained using ImageData.The function Show can be used to combine 2D vector graphics (or Graphics objects) with Image objects. Similarly, an image may be converted to a raster expression suitable for display with other Graphics primitives by applying Raster to it. An arbitrary Graphics expression may be converted to an image by applying the function Image to it.Image objects may also be inserted into a notebook by drag-and-drop from external applications. Image objects may be exported to a variety of standard image formats using Export, and images in a number of formats may be imported as Image objects using Import.

Upon output, an Image formats as a picture of the actual image, not as a 2D array of values.The data inside an image may take on a variety of values depending on if the image is binary, grayscale, RGB, CMYK, includes an alpha channel, etc. Images are commonly encountered in digital photography, digitization of text and pictures, scientific visualization, and a wide variety of other fields. In particular, an Image object contains a two-dimensional array of values (or lists of values) that represents a raster image. GIF, PNG, JPG) as found on the internet and elsewhere. Image provides unified symbolic representation for a large variety of digital image formats (e.g.Whether the image has transparency (alpha ) channel Information for Image may include the following properties:.

Arithmetic and statistical operations such as Log, Plus and Mean can work directly with images.Image effectively resets the options for an image.Image ] converts a Raster object to an image.Image effectively uses Rasterize to rasterize graphics.ColorSpace-> Automatic treats values as arbitrary channel intensities. ColorSpace-> cs specifies that values in the data should be interpreted as coordinates in a particular color space cs.

The following options can be specified:.

Image is treated as a raw object by functions like AtomQ, and for purposes of pattern matching.

Image can be used to convert between types.

Values in data are coerced to the specified type by rounding or clipping.

Image can be used to create an image of a specified data type.

Image by default allows any real number, but displays only values between 0 and 1.

The input array data can be given as a List, NumericArray, SparseArray, etc.

Rendered as red, green, blue values from 0 to 1Ĭhannel values rendered by equally spaced hues Rendered as gray level from 0 (black ) to 1 (white )

Elements of data can be any of the following:.

In Image, each element of data can specify values for any number of channels.

Image arranges successive rows of data down the page, and successive columns across.

Image displays in a notebook as an image.

Images are typically compressed and stored in formats such as TIFF, JPEG, PNG and more.

Images are rectangular grids of pixels captured by a camera or an imaging device.
