Adds a font_id for the given unichar_id. If the unichar_id is not in the shape, it is added.

Given an input pix, and a box, the sides of the box are shrunk inwards until they bound any black pixels found within the original box. The function c

Returns true if the provided word_choice is correct.

Claims the boxes in the boxes_list by marking them with a this owner pointer. If a box is already owned, then it must be owned by this.

Destroy the Pix if there is one, freeing memory.

Clears the given window and draws the featurespace guides for the appropriate normalization method.

Returns true if the point is contained within any of the outline boxes.

Copies the left/right tab from the src partition, but if take_box is true, copies the box instead and uses that as a key.

As CopyLeftTab, but with the right.

Returns a string listing the classes/fonts in a shape.

Deletes noise blobs from all lists where not owned by a ColPartition.

Main entry point for Paragraph Detection Algorithm. Given a set of equally spaced textlines (described by row_infos), Split them into paragraphs. Ou

NULL the owner of the blobs in this partition, so they can be deleted independently of the ColPartition.

Returns the width of a gap between the specified blob and the next one.

Getter for the description.

Returns a pointer to the page with the given index, modulo the total number of pages. Blocks until the background load is completed.

Gets a sample by its index.

Returns the horizontal overlap (by median) of this and other. WARNING! Only makes sense on vertical partitions!

Using djb2 hashing function to hash a 32-bit string introduced in http://www.cse.yorku.ca/~oz/hash.html

Expands the existing matrix in-place to make the band wider, without losing any existing data.

Bulk calls to Index. Maps the given array of features to a vector of sorted inT32 indices.
