Description

set_pixelset_pixelSetPixelSetPixelSetPixel sets pixel values: colors (set_colorset_colorSetColorSetColorSetColor, set_rgbset_rgbSetRgbSetRgbSetRgb, etc.) and gray values (set_grayset_graySetGraySetGraySetGray) 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_pixelGetPixelGetPixelGetPixel.

Window handle.

PixelPixelPixelPixelpixel (input_control)  integer(-array) HTupleHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Color lookup table index.

Default value: 128

Typical range of values: 0 ≤ Pixel Pixel Pixel Pixel pixel ≤ 255

Result

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