L_DlgInvertedText

#include "l_bitmap.h"

L_INT EXT_FUNCTION L_DlgInvertedText(hWndOwner, pDlgParams)

HWND hWndOwner;	/* owner of dialog */
LPINVERTEDTEXTDLGPARAMS pDlgParams;	/* pointer to a INVERTEDTEXTDLGPARAMS structure */

Displays the Inverted Text dialog box, and gets the options for L_InvertedTextBitmap. This function is available in the Document/Medical toolkits.

Parameter	Description
hWndOwner	Handle of the window which owns the dialog.
pDlgParams	Pointer to a INVERTEDTEXTDLGPARAMS 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_InvertedTextBitmap function only works with 1-bit images. If you provide a bitmap in the INVERTEDTEXTDLGPARAMS structure, it must be a 1-bit bitmap.

The Inverted Text dialog can be seen below:
