L_LTSCR_API L_INT L_CaptureMenuUnderCursor(pBitmap, uBitmapStructSize, pCaptureInfo, uInfoStructSize, pfnCaptureCallback, pUserData)
Captures an image of the selected menu's contents.
Pointer to a bitmap handle that references the captured data.
Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).
Address of LEADCAPTUREINFO structure to be filled with information regarding the captured image's source. Pass NULL if you are not interested in extra information about the capture.
Size in bytes, of the structure pointed to by pCaptureInfo, for versioning. Use sizeof(LEADCAPTUREINFO).
Optional callback function for additional processing.
If you do not provide a callback function, use NULL as the value of this parameter. If you do provide a callback function, use the function pointer as the value of this parameter. The callback function must adhere to the function prototype described in CAPTURECALLBACK Function.
Void pointer that you can use to pass one or more additional parameters that the callback function needs.
To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID ;*. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function captures the contents of the menu directly under the cursor to a bitmap. The callback can be used to do multiple captures, depending on the options set using L_SetCaptureOption.
The hot key needs to be pressed to complete the capture.
