L_LTDLG_API L_INT L_DlgInvertedText(hWndOwner, pDlgParams)
Displays the Inverted Text dialog box, and gets the options for L_InvertedTextBitmap.
This function is available in the Document/MedicalDocument/Medical toolkits.
Handle of the window which owns the dialog.
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 dialogs initial values.
| Value | Meaning |
|---|---|
| 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. |
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.
