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.
