The PDF labeling tool allows you to annotate text and arbitrary rectangular areas on PDF documents.
From the project’s Settings tab, enter the Label Set section.
Click on Add Category. From the list that appears, click on PDF.
A new row will appear named PDF. Click on it to expand it.
Give your PDF tool a title and description.
Enable the Required toggle if you want to force labelers to create a PDF label for each asset. When the toggle is disabled, labelers will be able to save and move to the next asset without creating the PDF label.
If you would like to ask labelers further questions, for example, if you want to show a further radio after placing a PDF tool, click on Add Classification and add a further question. More on nested questions here.
From the Tools panel on the left sidebar, select a PDF labeling tool, marked with an A enclosed in a square.
With the PDF tool selected, click and drag where you’d like the bounding box to be placed.
After performing OCR, Hub will display how confident it is that the OCR results are correct.
To perform OCR on a group of annotations at once, hold Shift then click on each annotation for which you'd like to perform OCR. Right-click on any one of them and click on OCR.
By default, targeted OCR only detects English. To change, add, or remove which languages should be detected in your project, head over to Settings -> General to do so:
To perform OCR on the area you've just drawn, click on the area to select it, then right-click it and click on the OCR button to perform OCR.
