参数签名

描述

convert_coordinates_window_to_imageconvert_coordinates_window_to_imageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImageconvert_coordinates_window_to_image converts window coordinates RowWindowRowWindowRowWindowRowWindowrowWindowrow_window and ColumnWindowColumnWindowColumnWindowColumnWindowcolumnWindowcolumn_window into image coordinates RowImageRowImageRowImageRowImagerowImagerow_image and ColumnImageColumnImageColumnImageColumnImagecolumnImagecolumn_image based on the displayed image part and the window size of the window defined in WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 未经并行化处理。

例程 (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)

结果

convert_coordinates_window_to_imageconvert_coordinates_window_to_imageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImageConvertCoordinatesWindowToImageconvert_coordinates_window_to_image returns 2 ( H_MSG_TRUE) if the window is valid. Otherwise an exception is raised.
