set_pixelset_pixelset_pixelSetPixelSetPixel (Operator)

Name

set_pixelset_pixelset_pixelSetPixelSetPixel — Define a color lookup table index.

Signature

Description

set_pixelset_pixelset_pixelSetPixelSetPixel sets pixel values: colors (set_colorset_colorset_colorSetColorSetColor, set_rgbset_rgbset_rgbSetRgbSetRgb, etc.) and gray values (set_grayset_grayset_graySetGraySetGray) are coded together into a number, called pixel. This 'pixel' is an index in the color lookup table. It ranges from 0 to 1 in b/w images and 0 to 255 color images with 8 bit planes. It is different from the 'pixel' ("picture element") in image processing. Therefore HALCON distinguishes between pixel and image element (or gray value).

The current value can be queried with get_pixelget_pixelget_pixelGetPixelGetPixel.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: local (may only be called from the same thread in which the window, model, or tool instance was created).
• Processed without parallelization.

Parameters

Result

set_pixelset_pixelset_pixelSetPixelSetPixel returns 2 (H_MSG_TRUE) if the parameter is correct and the window is valid. Otherwise an exception is raised.
