paint_xldpaint_xldPaintXldpaint_xldPaintXldPaintXld paints the XLD objects XLDXLDXLDXLDXLDXLD of type contour or
polygon with the constant gray values GrayvalGrayvalGrayvalGrayvalGrayvalgrayval into each channel
of the background image given in ImageImageImageImageImageimage and returns the result in
ImageResultImageResultImageResultImageResultImageResultimageResult. Open contours of XLD
objects are closed and their enclosed regions are filled up. The rim of
the subpixel XLD objects is painted onto the background image using
anti-aliasing.
Filling up XLD-objects that have crossings or segments that are very close
(lying in neighboring pixels) does not work correctly and leads to artifacts.
The set_systemset_systemSetSystemset_systemSetSystemSetSystem parameter 'neighborhood' defines whether
diagonal neighbors are filled as well as orthogonal neighbors.
GrayvalGrayvalGrayvalGrayvalGrayvalgrayval contains the gray values for painting the XLD objects. These
gray values can either be specified for each channel once, valid for all XLD
objects, or for each XLD object separately. To define the latter, group the
channel gray values g of each XLD object and concatenate them to
a tuple according to the order of the XLD objects, e.g., for a three channel
image:
[g(channel1,xld1), g(channel2,xld1), g(channel3,xld1), g(channel1,xld2), ... ].
If the input image is of type 'direction', gray values that are not
in the value range that is valid for 'direction' images are set to
the value 255 to mark them as invalid.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

paint_xldpaint_xldPaintXldpaint_xldPaintXldPaintXld returns 2 (H_MSG_TRUE) if all parameters are
correct. If the input is empty the behavior can be set via

If necessary, an exception is raised.
