Parameters

L_OcrPage page

OCR page of interest to sort its zones, if any.

const L_OcrPageSortedZonesIndexMapOptions *options

L_UINT **map

A pointer to pointer for an allocated array that contains the page zone indices listed such that the corresponding zones are in order from top to bottom and left to right.

L_UINT *count

The number of zones in the allocated map array. This value should be equivalent to the number of zones in the page.

Returns

Comments

This function does not change the index of any zone. It virtually sorts the zones from top to bottom and left to right, then it reports the indices of the virtually sorted zones. The first zone's index reproted is the first top-left zone, and the last zone's index reported is the last bottom-right zone.

The allocated map array should be freed using L_OcrMemory_Free.md function.
