The operator get_image_pointer3get_image_pointer3GetImagePointer3GetImagePointer3GetImagePointer3 returns a C pointer to
the three channels of a colored image (ImageRGBImageRGBImageRGBImageRGBimageRGB).
Additionally the image type (TypeTypeTypeTypetype = 'byte', 'int2','float' etc.)
and the image size (WidthWidthWidthWidthwidth and HeightHeightHeightHeightheight) are returned.
Consequently a direct access to the image data in the
HALCON database from the HALCON host language via the pointer is possible.
An image is stored in HALCON as a vector of image lines.
The image types 'complex' and 'vector_type' are handled in a specific way.
In particular, 'complex' images are interleaved, i.e., the real and the
imaginary parts are alternating, whereas 'vector_field' images consist of
two matrices, one for the rows and one for the columns, which are stored in
the HALCON database one after the other.
The three channels must have the same pixel type and the same size.
Only one image can be passed.
The operator get_image_pointer3get_image_pointer3GetImagePointer3GetImagePointer3GetImagePointer3 should only be used for entry
into newly created images, since otherwise the gray values of other images
might be overwritten (see relational structure).
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Pointer to the pixels of the first channel.
Pointer to the pixels of the second channel.
Pointer to the pixels of the third channel.
Type of image.

The operator get_image_pointer3get_image_pointer3GetImagePointer3GetImagePointer3GetImagePointer3 returns the value 2 (H_MSG_TRUE) if
exactly one image is passed.
The behavior in case of empty input (no input images available) is set via
the operator set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
If necessary an exception is raised.
