## Static Public Member Functions
static void | decode (const CiffComponent &ciffComponent, Image &image, ByteOrder byteOrder)
| Decode image metadata from a Crw entry convert and add it to the image metadata. This function converts only one Crw component.
static void | encode (CiffHeader *pHead, const Image &image)
| Encode image metadata from image into the Crw parse tree. This function converts all Exif metadata that Exiv2 can convert to Crw format, in a loop through the entries of the mapping table.
static void | loadStack (CrwDirs &crwDirs, uint16_t crwDir)
| Load the stack: loop through the Crw subdirs hierarchy and push all directories on the path from crwDir to root onto the stack crwDirs. Requires the subdirs array to be arranged in bottom-up order to be able to finish in only one pass.

## Detailed Description

Static class providing mapping functionality from Crw entries to image metadata and vice versa.

## Member Function Documentation

void Exiv2::CrwMap::decode | ( | const CiffComponent & | ciffComponent,
|  | Image & | image,
|  | ByteOrder | byteOrder
| ) | `[static]`

  | Decode image metadata from a Crw entry convert and add it to the image metadata. This function converts only one Crw component. Parameters:
  | ciffComponent | Source CIFF entry
  | image | Destination image for the metadata
  | byteOrder | Byte order in which the data of the entry is encoded

void Exiv2::CrwMap::encode | ( | CiffHeader * | pHead,
|  | const Image & | image
| ) | `[static]`

  | Encode image metadata from image into the Crw parse tree. This function converts all Exif metadata that Exiv2 can convert to Crw format, in a loop through the entries of the mapping table. Parameters:
  | pHead | Destination parse tree.
  | image | Source image containing the metadata.
