Label Editor Document Support

The Label Editor supports the following document file types:

• PDF (.pdf)

Document Label Support

Documents support the following label types:

• Bounding boxes
• Polygons
• Bitmasks
• Classifications

We recommend adding attributes to your label types when creating your Ontology for labeling documents.

The color you specify for each object label in your Ontology can make a big difference in the ease and effectiveness of labeling items. For example, lighter colors are more difficult to see on a white background.

Label Documents

Label display settings can help provide a better labeling experience for each annotator.

Press and hold the SHIFT key while using your mouse/trackpad to move around each page of a document.

Label PDFs

Annotate supports the following label types for PDFs:

• Bounding boxes
• Polygons
• Bitmasks
• Classifications

Classifications support being applied on a range of pages in a PDF.

Use Show text outline button feature when labeling documents to streamline your annotation process. When used with object label hotkeys, labeling becomes a smooth efficient process.

Bounding Boxes

1. Click the Show text outline button to enable the feature.
2. Press the hotkey for the bounding box, and the label appears around the area you highlight.

Bounding boxes are the quickest way to label documents in the Label Editor.

Bitmasks

1. Click the Show text outline button to enable the feature.
2. Press the hotkey for the bitmask, and then start labeling.

Polygons

1. Click the Show text outline button to enable the feature
2. Press the hotkey for the polygon, and then start labeling.

Using Relation Text Attributes - PDFs

Relation text attributes link an object to another object. In images or videos this could be linking a chicken’s body to its wing. In PDFs or text documents (text or HTML files) this could be linking words with measurements, or linking words with other words.

Your Ontology must MUST contain text attributes with the Relation feature enabled if you want to use relation text attributes.

While annotating, you can create a relationship between any object with a relation text attribute and any other object. After you create a relation between objects a workflow arrow points from the object with the relation text attribute to the other object.
