The SHAPEDLGPARAMS structure provides information used to initialize the dialog box created by the L_DlgGetShape function. After the user closes the dialog box, this structure is updated with information about the user's selections.
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Pointer to the bitmap handle that references the 1-bit bitmap used for preview or processing.
Pointer to the bitmap to be used for the background of the shape. This bitmap will be updated if the user chooses a new image using the Browse Image button. If you pass NULL, the "Tiled Image" and "Translucent Tiled Image" options will not appear in the BackStyle combo-box. The caller is responsible for freeing this bitmap when it is no longer needed.

Pointer to an optional help callback function. If you do not wish to provide help to this dialog, use NULL as the value of this parameter. To provide help to this dialog, use the function pointer as the value of this parameter. The callback function must adhere to the prototype described in LTCOMMDLGHELPCB.
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 pHelpCallBackUserData 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.
