Import an image:

Change the image type from 8-bit integer to a 64-bit real:

Convert a graphic to a bitmap image:

Import from a file:

Create from a region:

Create a grayscale image from a 2D array of data:

By default, data is assumed to be 0 to 1 and an image of type "Real32" is generated:

Create a color image from a 3D array of data:

Create an image from an array of colors:

Create an image of type "Byte":

Create a binary image from a 3×3 array:

Create an image from a SparseArray object:

Create a raster image from a Graphics object:

Create an image from a Graphics3D object:

Create an image from a GeoGraphics object:

Create a linear combination of two images:

Highlight edges in an image:

Compute statistical measures on images:

The value of a system option "IndeterminateValue" is used to replace values that cannot be stored in an image including ComplexInfinity and Indeterminate.

By default, 0 is used:

See the behavior using power:

Change the current value of the "IndeterminateValue" option:

Reset to the default 0:

By default, when generating images from data, no specific color space is assumed:

Check for the color space of an image with ImageColorSpace:

Specify the color space:

Generate a random RGB color image:

Random RGB image with alpha channel:

Generate a random gray-level image:

Random gray-level image with alpha channel:

Random CMYK image:

A CIE XYZ image:

Images with an arbitrary number of channels are stored with ColorSpace->Automatic:

Image channels should match the number of channels expected by the color space:

Change the interpretation of the pixel values in an image:

Use ColorConvert to convert the pixel values to a new space:

At the default magnification, ImageResolution72 means that 72 pixels will occupy an inch of the screen:

Changing the resolution affects the full display size of an image:

The value of ImageResolution may be automatically set by some functions:

Image with an explicit setting for the width:

With ImageSize->Automatic, images may appear larger or smaller than their actual size:

Use ImageSize->All to see images in their actual size:

Set the displayed size of an image:

Specifying both width and height will add white space if aspect ratios do not match:

By default, interleaved data is assumed:

Use Options to extract the Interleaving setting:

Create an image from planar data:

Image with data stored in three color planes:

Change an interleaved image to planar:

Image with an explicit magnification:

ImageSize and Magnification both control the display size of the image:

When both are set, ImageSize specification is used:

Add custom metainformation to an image:

Use Options to extract the metainformation:

Import puts metadata stored in the file into the MetaInformation option:
