描述

set_pixelset_pixelSetPixelSetPixelSetPixelset_pixel sets pixel values: colors (set_colorset_colorSetColorSetColorSetColorset_color, set_rgbset_rgbSetRgbSetRgbSetRgbset_rgb, etc.) and gray values (set_grayset_graySetGraySetGraySetGrayset_gray) 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_pixelGetPixelGetPixelGetPixelget_pixel。
