## GetImageColorspaceType

GetImageColorspaceType() returns the potential colorspace of image: sRGBColorspaceType, RGBColorspaceType, GRAYColorspaceType, etc.

To ensure the image type matches its potential, use SetImageColorspaceType():

        (void) SetImageColorspaceType(image,GetImageColorspaceType(image),
    exception);

The format of the GetImageColorspaceType method is:

    ColorspaceType GetImageColorspaceType(const Image *image,
      ExceptionInfo *exception)

A description of each parameter follows:

image
  the image.
exception
  return any errors or warnings in this structure.

## SetImageColorspace

SetImageColorspace() sets the colorspace member of the Image structure.

The format of the SetImageColorspace method is:

    MagickBooleanType SetImageColorspace(Image *image,
      const ColorspaceType colorspace)

A description of each parameter follows:

image
  the image.
colorspace
  the colorspace.

## SetImageGray

SetImageGray() returns MagickTrue if all the pixels in the image have the same red, green, and blue intensities and changes the type of the image to bi-level or grayscale.

The format of the SetImageGray method is:

    MagickBooleanType SetImageGray(const Image *image,
      ExceptionInfo *exception)

A description of each parameter follows:

image
  the image.
exception
  return any errors or warnings in this structure.

## SetImageMonochrome

SetImageMonochrome() returns MagickTrue if all the pixels in the image have the same red, green, and blue intensities and the intensity is either 0 or QuantumRange and changes the type of the image to bi-level.

The format of the SetImageMonochrome method is:

    MagickBooleanType SetImageMonochrome(const Image *image,
      ExceptionInfo *exception)

A description of each parameter follows:

image
  the image.
exception
  return any errors or warnings in this structure.

## TransformImageColorspace

TransformImageColorspace() transforms an image colorspace.

The format of the TransformImageColorspace method is:

    MagickBooleanType TransformImageColorspace(Image *image,
      const ColorspaceType colorspace)

A description of each parameter follows:

image
  the image.
colorspace
  the colorspace.
