gen_image1gen_image1GenImage1GenImage1 (Operator)


gen_image1gen_image1GenImage1GenImage1 — Create an image from a pointer to the pixels.


gen_image1( : Image : Type, Width, Height, PixelPointer : )

Herror gen_image1(Hobject* Image, const char* Type, const Hlong Width, const Hlong Height, const Hlong PixelPointer)

Herror T_gen_image1(Hobject* Image, const Htuple Type, const Htuple Width, const Htuple Height, const Htuple PixelPointer)

void GenImage1(HObject* Image, const HTuple& Type, const HTuple& Width, const HTuple& Height, const HTuple& PixelPointer)

void HImage::HImage(const HString& Type, Hlong Width, Hlong Height, void* PixelPointer)

void HImage::HImage(const char* Type, Hlong Width, Hlong Height, void* PixelPointer)

void HImage::GenImage1(const HString& Type, Hlong Width, Hlong Height, void* PixelPointer)

void HImage::GenImage1(const char* Type, Hlong Width, Hlong Height, void* PixelPointer)

static void HOperatorSet.GenImage1(out HObject image, HTuple type, HTuple width, HTuple height, HTuple pixelPointer)

public HImage(string type, int width, int height, IntPtr pixelPointer)

void HImage.GenImage1(string type, int width, int height, IntPtr pixelPointer)


The operator gen_image1gen_image1GenImage1GenImage1GenImage1 creates an image of the size WidthWidthWidthWidthwidth * HeightHeightHeightHeightheight. The pixels in PixelPointerPixelPointerPixelPointerPixelPointerpixelPointer are stored line-sequentially. The type of the given pixels (PixelPointerPixelPointerPixelPointerPixelPointerpixelPointer) must correspond to TypeTypeTypeTypetype (see gen_image_constgen_image_constGenImageConstGenImageConstGenImageConst 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 PixelPointerPixelPointerPixelPointerPixelPointerpixelPointer 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.

Example (C)

void NewImage(Hobject *new)
  unsigned char  image[768*525];
  int            r,c;
  for (r=0; r<525; r++)
    for (c=0; c<768; c++)
      image[r*768+c] = c % 255;


If the parameter values are correct, the operator gen_image1gen_image1GenImage1GenImage1GenImage1 returns the value 2 (H_MSG_TRUE). Otherwise an exception is raised.
