|  | int & | nTransparance
| ) |  |
| static

Return the r,g,b,a components of a color encoded in #RRGGBB[AA] format.

Maps to OGRStyleTool::GetRGBFromString().

Parameters

  pszColor | the color to parse
  nRed | reference to an int in which the red value will be returned.
  nGreen | reference to an int in which the green value will be returned.
  nBlue | reference to an int in which the blue value will be returned.
  nTransparance | reference to an int in which the (optional) alpha value will be returned.

Returns
  TRUE if the color could be successfully parsed, or FALSE in case of errors.

| static

Undocumented.

Parameters

  pszId | Undocumented
  pszWanted | Undocumented

Returns
  Undocumented

OGRStyleTool::GetStyleString | ( |  | ) |
| pure virtual

Get the style string for this Style Tool.

Maps to the OGRStyleTool subclasses' GetStyleString() methods.

Returns
  the style string for this style tool or "" if the hST is invalid.
