get_pixelT_get_pixelget_pixelGetPixelGetPixel (Operator)

Name

get_pixelT_get_pixelget_pixelGetPixelGetPixel — Get the current color lookup table index.

Signature

Description

get_pixelget_pixelget_pixelGetPixelGetPixel 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_colorset_colorSetColorSetColor or set_grayset_grayset_graySetGraySetGray), 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_grayvalget_grayvalGetGrayvalGetGrayval). Here a pixel is meant to be the color loookup table index.

With get_pixelget_pixelget_pixelGetPixelGetPixel 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_pixelset_pixelSetPixelSetPixel.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

get_part_styleget_part_styleget_part_styleGetPartStyleGetPartStyle returns 2 (H_MSG_TRUE) if the window is valid. Otherwise an exception is raised.
