Elements:

subimage

Position of the segmented or found area in the provided input image or position in the deskewed input image if the input image had to be deskewed.

result_flag

Specifies the type of the found area.

`RESULT_FLAG_NOTEXT`	picture, graphics or something else
`RESULT_FLAG_GRID`	line, box, grid of lines, or something like this
`RESULT_FLAG_UNDERLINE`	underline of a text line
`RESULT_FLAG_TEXT`	area of text lines

filler

8 byte alignment.

h_result_image_bw

Image handle of a black and white version of the segmented subimage. Call re_imagehandle2image() to get this black and white result_image. Call re_freeimage(*.h_result_image_bw) to free the related memory.

image_in

Image to be analyzed for layout.

expected_areas

Rectangles with text are searched. If rectangles are specified (expected), then only those are returned that correspond to the specification.

expected_areas_len

Number of specifications that can be found under expected_areas.

filler1;

8 byte alignment.

parameter

The default is 0. If LAYOUT_CONTENT_ONLY is set, the circumscribing rectangle will be delivered for the full page. LAYOUT_OPTIONS_FAST_GRID uses a quick search, which should only be used on dirt-free images.

image_deskewed

If the given image isn't correctly horizontally positioned, the corrected, deskewed image will be provided here.

h_image_deskewed

Image handle of the deskewed image, if this value or re_layout_deskew is different from 0. Call re_freeimage(*.h_image_deskewed) to free the allocated memory.

content

Found global area of interest in the given image, containing all results.

re_layout_deskew

Corrected skew of image_in. If different from 0, image_deskewed with h_image_deskewed is provided.

re_layout_result_len

Number of items in re_layout_result.

filler2[2]

8 byte alignment.

re_layout_result

Array of results of layout analysis. Call free(*.re_layout_result) to free memory.
