Adds a message entry to the message box.

Return whether the first word on the after line can fit in the space at the end of the before line (knowing which way the text is aligned and read).

(Re)Fit a line to the stored points. Returns false if the line is degenerate. Althougth the TabVector code mostly doesn't care about the direction of

Return true if no image has been set.

Returns true if there is a single blob in the list.

Return access to Tesseract internals.

Add entry to the heap, keeping the smallest item at the top, by operator<. Note that *entry is used as the source of operator=, but it is non-const to

Clear the grid and get rid of the tab vectors, but not separators, ready to start again.

Sets all blobs with the partition blob type and flow, but never overwrite leader blobs, as we need to be able to identify them later.
