描述
get_font_extentsget_font_extentsGetFontExtentsGetFontExtentsGetFontExtentsget_font_extents queries the maximum width
(MaxWidthMaxWidthMaxWidthMaxWidthmaxWidthmax_width), height (MaxHeightMaxHeightMaxHeightMaxHeightmaxHeightmax_height), and extension
above and below the baseline (MaxAscentMaxAscentMaxAscentMaxAscentmaxAscentmax_ascent and
MaxDescentMaxDescentMaxDescentMaxDescentmaxDescentmax_descent, respectively) of the font that is currently set
for the window WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle. The sizes are measured in
pixels.
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。
