virtual L_INT LDialogWeb::DoModalHTMLMapper(hWndOwner)
Displays the HTML Map Creator dialog, in order to create an HTML map upon an image. Use this dialog to create an HTML map area using the given bitmap.
Handle of the window which owns the dialog.
| Value | Meaning |
|---|---|
| SUCCESS_DLG_OK | The "OK" button was pressed, and the dialog exited successfully. |
| SUCCESS_DLG_CLOSE | The "Close" 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. |
LDialogWeb::SetHTMLMapperParams must be called before using this function to set the initial values for the dialog. You can get the updated HTMLMAPPERDLGPARAMS with the values entered by the user through the dialog by using LDialogWeb::GetHTMLMapperParams.
This dialog also offers tuning options for the output bitmap through the dialogs displayed using LDialogWeb::DoModalJPEGWebTuner, LDialogWeb::DoModalGIFWebTuner and LDialogWeb::DoModalPNGWebTuner.
