DL_TEXTLINEGT

The DL_TEXTLINEGT zone type is a predefined zone type used for groundtruthing text. This zone type makes entering and viewing the text contents of a zone faster, and allows the addition of text offsets for proper text alignment within the zone. This zone type can be created in the Zones tab of the Preferences menu.

Entering text into a DL_TEXTLINEGT Zone

To enter the text contents of a DL_TEXTLINEGT zone, right click inside the zone. A contents window will appear above the zone where you can type in the text. When you are done, press OK to save the text you entered, or CANCEL to cancel your changes.

Offsets

Adding offsets to a DL_TEXTLINEGT Zone

Before adding text offsets, enter in all the text contents of the zone. Offsets can align text by the character, word, or line. To change the unit of alignment, change the "segmentation" attribute of the zone. To add offsets, first select the zone by clicking inside it or by dragging a box around it. Then hold Ctrl and click on the zone where you want the offset be added. You are limited to adding one less offset than the number of units of segmentation in the text for the zone.

Moving offsets in a DL_TEXTLINEGT Zone

To move offsets within a zone, first select the zone by clicking inside it or by dragging a box around it. Then mouse over the offset, until the cursor changes to two arrows pointing away from the offset. Grab the offset by pressing the left mouse button, and drag it to its new location.

Deleting offsets in a DL_TEXTLINEGT Zone

To delete offsets within a zone, first select the zone by clicking inside it or by dragging a box around it. Then mouse over the offset, and click to select the offset. Once the offset is highlighted, you can press the Delete key to remove the offset.
