get_pixelT_get_pixelGetPixelGetPixel (Operator)


get_pixelT_get_pixelGetPixelGetPixel — Get the current color lookup table index.


get_pixelget_pixelGetPixelGetPixelGetPixel is obsolete and is only provided for reasons of backward compatibility.


get_pixel( : : WindowHandle : Pixel)

Herror T_get_pixel(const Htuple WindowHandle, Htuple* Pixel)

void GetPixel(const HTuple& WindowHandle, HTuple* Pixel)

HTuple HWindow::GetPixel() const

static void HOperatorSet.GetPixel(HTuple windowHandle, out HTuple pixel)

HTuple HWindow.GetPixel()


get_pixelget_pixelGetPixelGetPixelGetPixel 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_colorset_colorSetColorSetColorSetColor or set_grayset_graySetGraySetGraySetGray), 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_grayvalget_grayvalGetGrayvalGetGrayvalGetGrayval). Here a pixel is meant to be the color loookup table index.

With get_pixelget_pixelGetPixelGetPixelGetPixel it is possible to save the output mode without knowing whether colors or gray values are used. PixelPixelPixelPixelpixel is set with the operator set_pixelset_pixelSetPixelSetPixelSetPixel.
