L_ConvertCurveTypeToBuffer

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_ConvertCurveTypeToBuffer(pData, pIccTagCurveType)

L_UCHAR * pData;	/* pointer to a buffer */
pICCTAG_CURVE_TYPE pIccTagCurveType;	/* pointer to a structure */

Converts the information of an ICCTAG_CURVE_TYPE structure into one buffer of sequential bytes.

Parameter	Description
pData	Pointer to a buffer to be updated with the converted information as one buffer of sequential bytes.
pIccTagCurveType	Pointer to an ICCTAG_CURVE_TYPE structure that contains the information to be converted into one buffer of sequential data.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The pData pointer must be allocated by the user. Its size must be equal to the size, in bytes, of the structure pointed to by the pIccTagCurveType parameter.

The size of the pData buffer can be calculated as follows: 4 + 4 + 4 + 2 * pIccTagCurveType.Curve.uCurveCount. For more information, refer to the ICC.1:2004-10 specification page 39 in the (www.color.org) website.

Example

/* This example converts a ICCTAG_CURVE_TYPE structure into a buffer */
L_UCHAR* ConvertCurveTypeToBufferExample(pICCTAG_CURVE_TYPE pIccCurveType, L_INT* pnRet)
{
   L_UCHAR L_FAR * pData;
   L_INT nDataSize;

   // calculate the data size
   nDataSize = 4 + 4 + 4 + 2 * pIccCurveType->Curve.uCurveCount;

   // then allocate the destination data pointer
   pData = (L_UCHAR L_FAR *) malloc(nDataSize, sizeof(L_UCHAR));
   if (pData == NULL)
      return ERROR_NO_MEMORY;

   // now convert it into buffer
   *pnRet = L_ConvertCurveTypeToBuffer(pData, pIccCurveType);
   return pData;
