Create a function of this type to give your application the flexibility of replacing ImageGear's memory reallocation routine with your own.
Declaration:
|
Copy Code
|
typedef LPBYTE (ACCUAPI LPFNIG_MEM_REALLOC) (
LPBYTE lpBuffer,
AT_UINT nSize
);
|
Arguments:
Name |
Type |
Description |
lpBuffer |
LPBYTE |
Far pointer to the buffer to be reallocated. |
nSize |
AT_UINT |
New byte count for realloc buffer. |
Return Value:
The user supplied callback function should return a pointer to the allocated block of memory.
Supported Raster Image Formats:
This function does not process image pixels.
Sample:

Example:
|
Copy Code
|
***********************************************************/
/* Memory ReAlloc callback function definition */
***********************************************************/
LPBYTE ACCUAPI MyMemReAlloc( LPBYTE lpbuffer, AT_UINT nSize)
{
/* Put your memory reallocation code here */
return( lpBuffer);
};
/*See also example for IG_mem_CB_register() */
|
Remarks:
This callback function is registered by calling IG_mem_CB_register(). The register function must be called prior to any user-defined callback functions being used by the ImageGear library.
