| <p>AcquireColorCache() caches one or more color configurations which provides a mapping between color attributes and a color name.</p> |

| |
| <p>GetColorInfoList() returns any colors that match the specified pattern.</p> |
| |
| <p>The format of the GetColorInfoList function is:</p> |
| |
| <pre class="text"> |

| <h2><a href="http://nextgen.imagemagick.org/api/MagickCore/color_8c.html" id="ListColorInfo">ListColorInfo</a></h2> |
| |
| <p>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.</p> |
| |
| <p>The format of the ListColorInfo method is:</p> |
| |
| <pre class="text"> |
| MagickBooleanType ListColorInfo(FILE *file,ExceptionInfo *exception) |
| </pre> |
| |
| <p>A description of each parameter follows.</p> |
| |
| <dt>file</dt> |
| <p>List color names to this file handle.</p> |
| |
| <dt>exception</dt> |
| <p>return any errors or warnings in this structure.</p> |
| |
| <h2><a href="http://nextgen.imagemagick.org/api/MagickCore/color_8c.html" id="QueryColorname">QueryColorname</a></h2> |
| |
| <p>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.</p> |
| |
| <p>UPDATE: the 'image' argument is no longer needed as all information should have been preset using GetPixelInfo().</p> |
| |
| <p>The format of the QueryColorname method is:</p> |
| |
| <pre class="text"> |
| MagickBooleanType QueryColorname(const Image *image, |
| const PixelInfo *color,const ComplianceType compliance,char *name, |
| ExceptionInfo *exception) |
| </pre> |
| |
| <p>A description of each parameter follows.</p> |
| |
| <dt>image</dt> |
| <p>the image. (not used! - color gets settings from GetPixelInfo()</p> |
| |
| <dt>color</dt> |
| <p>the color intensities.</p> |
| |
| <dt>Compliance</dt> |
| <p>Adhere to this color standard: SVG, X11, or XPM.</p> |
| |
| <dt>name</dt> |
| <p>Return the color name or hex value.</p> |

| <dt>exception</dt> |
| <p>return any errors or warnings in this structure.</p> |
