get_pixel — Get the current color lookup table index.
get_pixel is obsolete and is only provided for reasons of backward compatibility.
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 loookup 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.
Index of the current color look-up table.
get_part_style returns 2 (H_MSG_TRUE) if the window is valid. Otherwise an exception is raised.
