名称
get_window_pointer3T_get_window_pointer3GetWindowPointer3GetWindowPointer3get_window_pointer3 — 访问窗口的像素数据。
警告
This operator does not work in an HDevelop graphics window opened with
dev_open_window.

def get_window_pointer3(window_handle: HHandle) -> Tuple[int, int, int, int, int]
描述
get_window_pointer3get_window_pointer3GetWindowPointer3GetWindowPointer3GetWindowPointer3get_window_pointer3 enables (in some window systems) the
direct access to the bitmap. Result values are the three pointers on the
color extracts of a 24-bit window (ImageRedImageRedImageRedImageRedimageRedimage_red, ImageGreenImageGreenImageGreenImageGreenimageGreenimage_green,
ImageBlueImageBlueImageBlueImageBlueimageBlueimage_blue), as well as the window size (WidthWidthWidthWidthwidthwidth,
HeightHeightHeightHeightheightheight).
In the language C the type of the image points is unsigned char.
注意
get_window_pointer3get_window_pointer3GetWindowPointer3GetWindowPointer3GetWindowPointer3get_window_pointer3 is usable only for window type
'pixmap'"pixmap""pixmap""pixmap""pixmap""pixmap".
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
