AcquireColorCache
AcquireColorCache() caches one or more color configurations which provides a mapping between color attributes and a color name.
The format of the AcquireColorCache method is:
LinkedListInfo *AcquireColorCache(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.
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.
List color names to this file handle.
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 hex value is returned instead. For example an intensity of rgb:(0,0,0) returns black whereas rgb:(223,223,223) returns #dfdfdf.
UPDATE: the 'image' argument is no longer needed as all information should have been preset using GetPixelInfo().
The format of the QueryColorname method is:
MagickBooleanType QueryColorname(const Image *image, const PixelInfo *color,const ComplianceType compliance,char *name, ExceptionInfo *exception)
A description of each parameter follows.
the image. (not used! - color gets settings from GetPixelInfo()
the color intensities.
Adhere to this color standard: SVG, X11, or XPM.
Return the color name or hex value.
return any errors or warnings in this structure.
