Beschreibung
convert_coordinates_window_to_imageconvert_coordinates_window_to_imageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImage konvertiert Fensterkoordinaten
RowWindowRowWindowRowWindowRowWindowrowWindow und ColumnWindowColumnWindowColumnWindowColumnWindowcolumnWindow in Bildkoordinaten
RowImageRowImageRowImageRowImagerowImage und ColumnImageColumnImageColumnImageColumnImagecolumnImage basierend auf dem Bildausschnitt
und der Fenstergröße des durch WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle gegebenen Fensters.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.

Beispiel (HDevelop)
read_image (Image, 'printer_chip/printer_chip_01')
dev_get_window (WindowHandle)
get_window_extents (WindowHandle, Row, Column, Width, Height)
dev_set_part (450, 300, 750, 600)
dev_display (Image)
*
* Generate rectangle in image coordinates
Row := [474, 746]
Column := [314, 589]
gen_rectangle1 (Rectangle1, Row[0], Column[0], Row[1], Column[1])
* Convert rectangle corner points to window coordinates
convert_coordinates_image_to_window (WindowHandle, Row[[0,1,0,1]], \
Column[[0,0,1,1]], RowWindow, ColumnWindow)
*
* Window center in window coordinates
WindowCenterRow := Height/2-1
WindowCenterColumn := Width/2-1
* Convert window center to image coordinates
convert_coordinates_window_to_image (WindowHandle, WindowCenterRow, \
WindowCenterColumn, RowImage, ColumnImage)
*
* Display all points in image coordinates
dev_display (Image)
disp_cross (WindowHandle, Row[[0,1,0,1]], Column[[0,0,1,1]], 6, rad(45))
disp_cross (WindowHandle, RowImage, ColumnImage, 6, 0)
Ergebnis
convert_coordinates_window_to_imageconvert_coordinates_window_to_imageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImage liefert den Wert 2 (H_MSG_TRUE), falls das
Fenster gültig ist. Ansonsten wird eine Fehlerbehandlung durchgeführt.
