Function Documentation

U16 wmf_aldus_checksum (  wmfAPI *    API )

Compute the Aldus checksum of the metafile's header. Parameters: API  the API handle (Must read the header first, either via wmf_scan() or by calling wmf_header_read() directly.) Returns: Returns the checksum.

const char* wmf_attr_add (  wmfAPI *   , wmfAttributes *   , const char *   , const char *    )

Add an name&value to a wmfAttributes structure; returns ptr to value-in-list

void wmf_attr_clear (  wmfAPI *   , wmfAttributes *    )

Clear/Empty a wmfAttributes structure

void wmf_attr_free (  wmfAPI *   , wmfAttributes *    )

Free memory associated with a wmfAttributes structure

void wmf_attr_new (  wmfAPI *   , wmfAttributes *    )

Initialize a wmfAttributes structure

const char* wmf_attr_query (  wmfAPI *   , wmfAttributes *   , const char *    )

Return value of name in a wmfAttributes structure; returns 0 if name not found

wmf_error_t wmf_header_read (  wmfAPI *    API )

Read the metafile's header. Parameters: API  the API handle (Must read the header first, either via wmf_scan() or by calling wmf_header_read() directly.) Returns: Returns the library error state (wmf_E_None on success). Possible library error states of wmf_E_Glitch, wmf_E_BadFormat (bad header), wmf_E_BadFile (no open input stream) and wmf_E_EOF (premature end-of-file).

U16 wmf_read_16 (  wmfAPI *    )

Reads a two-byte sequence from the current metafile, returns U16

U32 wmf_read_32 (  wmfAPI *   , U16 *   , U16 *    )

Reads a four-byte sequence from the current metafile, returns U32

void wmf_write (  wmfAPI *   , unsigned    long, unsigned    int, const char *   , char **   , const unsigned char *   , unsigned    long )

Writes to --wmf-write file (which may be WMF or home-made wmfxml)

void wmf_write_begin (  wmfAPI *   , const char *    )

Open --wmf-write file (which may be WMF or home-made wmfxml)

void wmf_write_end (  wmfAPI *    )

Close --wmf-write file (which may be WMF or home-made wmfxml)
