get_pixel 已过时,仅出于向后兼容性考虑而保留。
get_pixel( : : WindowHandle : Pixel)
get_pixel returns the internal coding of the output
gray value or color, respectively, for the window. If the output mode is
set to color(s) or gray value(s) (see set_color or
set_gray), then the color- or gray values are transformed
for internal use. The internal code is then used for (physical)
screen display. The transformation depends on the mapping
characteristics and the condition of the output device and can be
different in different program runs. Don't confuse the term “pixel”
with the term “pixel” in image processing (the other operator
is get_grayval). Here a pixel is meant to be the
color lookup table index.
With get_pixel it is possible to save the output mode
without knowing whether colors or gray values are
used. Pixel is set with the operator
set_pixel。
