The operator gen_image1gen_image1GenImage1gen_image1GenImage1GenImage1 creates an image of the size WidthWidthWidthWidthWidthwidth * HeightHeightHeightHeightHeightheight. The pixels in PixelPointerPixelPointerPixelPointerPixelPointerPixelPointerpixelPointer are stored line-sequentially. The type of the given pixels (PixelPointerPixelPointerPixelPointerPixelPointerPixelPointerpixelPointer) must correspond to TypeTypeTypeTypeTypetype (see gen_image_constgen_image_constGenImageConstgen_image_constGenImageConstGenImageConst for a more detailed description of the pixel types). The storage for the new image is newly created by HALCON. Thus, the storage on the PixelPointerPixelPointerPixelPointerPixelPointerPixelPointerpixelPointer can be released after the call. Note that how to pass a pointer value depends on the used operator signature and programming environment. Make sure to pass the actual memory address where the image data is stored, not the address of a pointer variable. Care must be taken not to truncate 64-bit pointers on 64-bit architectures.

    for (c=0; c<768; c++)
      image[r*768+c] = c % 255;


If the parameter values are correct, the operator gen_image1gen_image1GenImage1gen_image1GenImage1GenImage1 returns the value 2 (H_MSG_TRUE). Otherwise an exception is raised.
