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 LDicomDS::GetImageList.
|
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 LDicomDS::GetImageList 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 LDicomDS::GetImageList 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 LDicomDS::GetImageList function has two overload functions. GETIMAGECALLBACK is used with the version that has a callback.
