   ↳ com.google.android.gms.vision.text.Element

Class Overview

Roughly equivalent to a space-separated "word" in most Latin languages, or a character in others. For instance, if a word is split between two lines by a hyphen, each part is encoded as a separate Element.

Public Methods

public Rect getBoundingBox ()

Axis-aligned bounding box containing the text. The bounding box may extend past the image boundary.

public List<? extends Text> getComponents ()

Smaller components that comprise this entity, if any. If this entity is an atom, an empty list is returned. TextBlock is at the top of the Text hierarchy. TextBlock contains Line objects, which contains Elements. Elements are atoms. We may decide to add character-level objects in later versions. For example, a client could draw bounding boxes for recognized text in different colors for paragraphs, lines, words, and alphabets by repeatedly traversing down the tree with this method.

public Point[] getCornerPoints ()

Four corner points in clockwise direction starting with top-left. Due to the possible perspective distortions, this is not necessarily a rectangle. Parts of the region could be outside of the image.

public String getLanguage ()

public String getValue ()

Retrieve the recognized text as a string. Returned in reading order for the language. For Latin, this is top to bottom within a TextBlock, and left-to-right within Lines.
