#include "ltdic.h"

L_BOOL pEXT_CALLBACK YourFunction(nIndex, nCount, pUserData)

L_UINT32 nIndex;

index of the image to load

L_UINT32 nCount;

number of images to load

L_VOID * pUserData;

pointer to additional data

Called for each image that is loaded using L_DicomGetImageList.

Parameter

Description

nIndex

Zero-based index of the image to load.

nCount

Total number of images to be loaded. This is the same value passed to the L_DicomGetImageList function.

pUserData

Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the L_DicomGetImageList function.)

 

Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

TRUE

Continue loading.

FALSE

Abort loading.

Comments

The L_DicomGetImageList function has two overload functions. GETIMAGECALLBACK is used with the version that has a callback.
