L_ConvertParametricCurveTypeToBuffer

#include "l_bitmap.h"

L_LTCLR_API L_INT L_ConvertParametricCurveTypeToBuffer(pData, pIccTagParametricCurveType)

L_UCHAR * pData;	/* pointer to a buffer */
pICCTAG_PARAMETRIC_CURVE_TYPE pIccTagParametricCurveType;	/* pointer to a structure */

Converts the information in an ICCTAG_PARAMETRIC_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.
pIccTagParametricCurveType	Pointer to an ICCTAG_PARAMETRIC_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 pIccTagParametricCurveType parameter.

The size of pData buffer can be calculated as follows: 4 + 4 + 2 + 2 + 4 * number of parameters retrieved by calling the L_GetParametricCurveNumberOfParameters function. For more information, refer to the ICC.1:2004-10 specification page 56 in the (www.color.org) website.

Example

//This example converts a ICCTAG_PARAMETRIC_CURVE_TYPE structure into a buffer

L_UCHAR* ConvertParametricCurveTypeToBufferExample(pICCTAG_PARAMETRIC_CURVE_TYPE pIccParametricCurveType, L_INT* pnRet) 
{
   L_UCHAR* pData; 
   L_INT nDataSize; 
   // calculate the data size
   nDataSize = 4 + 4 + 2 + 2 + 4 * L_GetParametricCurveNumberOfParameters((ICCFUNCTIONTYPE) pIccParametricCurveType->ParametricCurve.uFunctionType); 
   // then allocate the destination data pointer
   pData = (L_UCHAR*) calloc(nDataSize, sizeof(L_UCHAR)); 
   if (pData == NULL) 
   {
      *pnRet = ERROR_NO_MEMORY;
      return NULL; 
   }
   // now convert it into a buffer
   *pnRet = L_ConvertParametricCurveTypeToBuffer(pData, pIccParametricCurveType);
   if(*pnRet != SUCCESS)
      return NULL;
   return pData;
