GetColorInfoList

GetColorInfoList() returns any colors that match the specified pattern.

The format of the GetColorInfoList function is:

  const ColorInfo **GetColorInfoList(const char *pattern,
    size_t *number_colors,ExceptionInfo *exception)

A description of each parameter follows:

pattern

    Specifies a pointer to a text string containing a pattern.

number_colors

    This integer returns the number of colors in the list.

exception

    return any errors or warnings in this structure.

GetColorList

GetColorList() returns any colors that match the specified pattern.

The format of the GetColorList function is:

  char **GetColorList(const char *pattern,size_t *number_colors,
    ExceptionInfo *exception)

A description of each parameter follows:

pattern

    Specifies a pointer to a text string containing a pattern.

number_colors

    This integer returns the number of colors in the list.

exception

    return any errors or warnings in this structure.

ListColorInfo

ListColorInfo() lists color names to the specified file. Color names are a convenience. Rather than defining a color by its red, green, and blue intensities just use a color name such as white, blue, or yellow.

The format of the ListColorInfo method is:

  MagickBooleanType ListColorInfo(FILE *file,ExceptionInfo *exception)

A description of each parameter follows.

file

    List color names to this file handle.

exception

    return any errors or warnings in this structure.

LoadColorList

LoadColorList() loads one or more color configuration file which provides a mapping between color attributes and a color name.

The format of the LoadColorLists method is:

  MagickBooleanType LoadColorLists(const char *filename,
    ExceptionInfo *exception)

A description of each parameter follows:

filename

    the font file name.

exception

    return any errors or warnings in this structure.

QueryColorDatabase

QueryColorDatabase() returns the red, green, blue, and opacity intensities for a given color name.

The format of the QueryColorDatabase method is:

  MagickBooleanType QueryColorDatabase(const char *name,
    const ComplianceType compliance,PixelPacket *color,
    ExceptionInfo *exception)

A description of each parameter follows:

name

    the color name (e.g. white, blue, yellow).

compliance

    Adhere to this color standard: SVG, X11, or XPM.

color

    the red, green, blue, and opacity intensities values of the named color in this structure.

exception

    return any errors or warnings in this structure.

QueryColorDatabase

QueryColorDatabase() returns the red, green, blue, and opacity intensities for a given color name.

The format of the QueryColorDatabase method is:

  MagickBooleanType QueryColorDatabase(const char *name,PixelPacket *color,
    ExceptionInfo *exception)

A description of each parameter follows:

name

    the color name (e.g. white, blue, yellow).

color

    the red, green, blue, and opacity intensities values of the named color in this structure.

exception

    return any errors or warnings in this structure.

QueryColorname

QueryColorname() returns a named color for the given color intensity. If an exact match is not found, a rgb() color is returned instead.

The format of the QueryColorname method is:

  MagickBooleanType QueryColorname(const Image *image,
    const PixelPacket *color,const ComplianceType compliance,char *name,
    ExceptionInfo *exception)

A description of each parameter follows.

image

    the image.

color

    the color intensities.

compliance

    Adhere to this color standard: SVG, X11, or XPM.

name

    Return the color name or hex value.

exception

    return any errors or warnings in this structure.

QueryMagickColorCompliance

QueryMagickColorCompliance() returns the red, green, blue, and opacity intensities for a given color name and standards compliance.

The format of the QueryMagickColor method is:

  MagickBooleanType QueryMagickColor(const char *name,
    const ComplianceType compliance,MagickPixelPacket *color,
    ExceptionInfo *exception)

A description of each parameter follows:

name

    the color name (e.g. white, blue, yellow).

compliance

    Adhere to this color standard: SVG, X11, or XPM.

    the red, green, blue, and opacity intensities values of the named color in this structure.

exception

    return any errors or warnings in this structure.

QueryMagickColor

QueryMagickColor() returns the red, green, blue, and opacity intensities for a given color name.

The format of the QueryMagickColor method is:

  MagickBooleanType QueryMagickColor(const char *name,
    MagickPixelPacket *color,ExceptionInfo *exception)

A description of each parameter follows:

name

    the color name (e.g. white, blue, yellow).

color

    the red, green, blue, and opacity intensities values of the named color in this structure.

    return any errors or warnings in this structure.

QueryMagickColorname

QueryMagickColorname() returns a named color for the given color intensity. If an exact match is not found, a hex value is returned instead. For example an intensity of rgb:(0,0,0) returns black whereas rgb:(223,223,223) returns #dfdfdf.

The format of the QueryMagickColorname method is:

  MagickBooleanType QueryMagickColorname(const Image *image,
    const PixelPacket *color,const ComplianceType compliance,char *name,
    ExceptionInfo *exception)

A description of each parameter follows.

image

    the image.

color

    the color intensities.

Compliance

    Adhere to this color standard: SVG, X11, or XPM.

name
