Description

paint_xldpaint_xldpaint_xldPaintXldPaintXld paints the XLD objects XLDXLDXLDXLDXLD of type contour or polygon with the constant gray values GrayvalGrayvalGrayvalGrayvalgrayval into each channel of the background image given in ImageImageImageImageimage and returns the result in ImageResultImageResultImageResultImageResultimageResult. 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. Note that only objects without crossings or touching segments are painted correctly.

GrayvalGrayvalGrayvalGrayvalgrayval 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), ... ].

Parameters

XLDXLDXLDXLDXLD (input_object)  xld(-array) → objectHXLDHXLDHXLDXHobject

XLD objects to be painted into the input image.

ImageImageImageImageimage (input_object)  image → objectHImageHImageHImageXHobject (byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex)

Image in which the xld objects are to be painted.

ImageResultImageResultImageResultImageResultimageResult (output_object)  image → objectHImageHImageHImageXHobject * (byte / direction / cyclic / int1 / int2 / uint2 / int4 / real / complex)

Image containing the result.

GrayvalGrayvalGrayvalGrayvalgrayval (input_control)  number(-array) → HTupleHTupleVARIANTHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong) (double / Hlong)

Desired gray value of the xld object.

Default value: 255.0

Suggested values: 0.0, 1.0, 2.0, 5.0, 10.0, 16.0, 32.0, 64.0, 128.0, 253.0, 254.0, 255.0

Example (HDevelop)

* Paint colored xld objects into a gray image

* read and copy image to generate a three channel image
read_image(Image1,'green-dot')
copy_image(Image1,Image2)
copy_image(Image1,Image3)
compose3(Image1,Image2,Image3,Image)
* extract subpixel border
threshold_sub_pix(Image1,Border,128)
* select the circle and the arrows
select_obj(Border,circle,14)
select_obj(Border,arrows,16)
concat_obj(circle,arrows,green_dot)
* paint a green circle and white arrows (to paint all
* objects e.g. blue, pass [0,0,255] tuple for GrayVal)
paint_xld(green_dot,Image,ImageResult,[0,255,0,255,255,255])

Example (C)

/* select the circle and the arrows */
select_obj(Border,&circle,14);
select_obj(Border,&arrows,16);
concat_obj(circle,arrows,&green_dot);
/* paint a green circle and white arrows,
 * therefore define tuple grayval:=[0,255,0,255,255,255].
 * (to paint all objects e.g. blue define grayval:=[0,0,255]) */

Result

paint_xldpaint_xldpaint_xldPaintXldPaintXld returns 2 (H_MSG_TRUE) if all parameters are correct. If the input is empty the behavior can be set via set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
