#include "l_bitmap.h"

L_INT EXT_FUNCTION L_DlgDotRemove(hWndOwner, pDlgParams)

HWND hWndOwner;	/* owner of dialog */
LPDOTREMOVEDLGPARAMS pDlgParams;	/* pointer to a DOTREMOVEDLGPARAMS structure */

Displays the Dot Remove dialog box, and gets the options for L_DotRemoveBitmap. This function is available in the Document/Medical toolkits.

Parameter	Description
hWndOwner	Handle of the window which owns the dialog.
pDlgParams	Pointer to a DOTREMOVEDLGPARAMS structure to be updated with the values entered by the user, through the dialog. Set members of this structure, before calling this function, to set the dialog’s initial values.

Returns

SUCCESS_DLG_OK	The "OK" button was pressed, and the dialog exited successfully.
SUCCESS_DLG_CANCEL	The "Cancel" button was pressed, and the dialog exited successfully.
< 1	An error occurred. Refer to Return Codes.

Comments

The L_DotRemoveBitmap function only works with 1-bit images. If you provide a bitmap in the DOTREMOVEDLGPARAMS structure, it must be a 1-bit bitmap.

The Dot Remove dialog can be seen below:
