You can create a reference layout for each image in the batch. The reference layout shows where you want blocks to be located on the image. You can create a reference layout manually or from the results of matching the FlexiLayout, and you can edit it by adding or removing blocks and by changing their sizes and positions. Reference layouts are used when debugging FlexiLayouts, because they let you compare the results of matching your FlexiLayout with the block locations on each image. ## Reference layout and Difference layout modes You create reference layouts in **Reference layout** mode. To switch to this mode, click Reference layout button on the toolbar. **Difference layout** mode (Difference layout button button on the toolbar) shows the difference between the reference layout and the results of matching the FlexiLayout. It highlights two kinds of area: * **Missing Areas** – Areas present in the reference layout blocks but absent from the blocks detected by matching the FlexiLayout, highlighted in red. * **Excess Areas** – Areas absent from the reference layout blocks but present in the blocks detected by matching the FlexiLayout, highlighted in green. The **Batch** window shows the percentages of **Missing Areas** and **Excess Areas**. ## Create a reference layout manually Open the image you want to create a reference layout for. For more information, see [Match the FlexiLayout with images](/flexi-capture/fls/settings/analyze). Click Reference layout button on the toolbar. Draw the blocks you need with the [Block-Drawing Tools toolbar](/flexi-capture/fls/interface/toolbars#blockdrawingtools). Click Save button on the toolbar. ## Create a reference layout from a matched FlexiLayout Open the image you want to create a reference layout for. For more information, see [Match the FlexiLayout with images](/flexi-capture/fls/settings/analyze). Select **Copy Matched Layout to Reference** from the **Batch** menu or the shortcut menu. Move or resize the blocks if the copied layout needs correcting. Click Save button on the toolbar. You can also use the **Copy Matched Layout to Reference** command on the shortcut menu of the batch to save the results of matching the FlexiLayout with selected batch pages as a reference layout. ## Reference layout tools The commands for creating and editing blocks are available in **View → Images → Tool → Select**. The corresponding buttons are on the toolbar. ### Move a block border Click the **Select** tool on the toolbar, or select it in **View → Images → Tool**. Place the mouse pointer on the block border you want to move. Hold down the left mouse button, drag the border in the direction you want, and release. If you place the mouse pointer in the corner of the block, dragging the mouse moves both the vertical and horizontal block borders. ### Move a selected block Click the **Select** tool on the toolbar, or select it in **View → Images → Tool**. Place the mouse pointer on the block. The pointer changes shape to show that you can move the block. Hold down the left mouse button, drag the block in the direction you want, and release. Sometimes a block is too small to move, because its borders are very close together and pointing at any of them activates the change-size mode. Hold down the **Ctrl** key to move such blocks. ### Create a new block Click the **Create Block** tool on the toolbar, or select it in **View → Images → Tool**. Place the mouse pointer in the corner of the new block, hold down the left mouse button, drag the corner diagonally in the direction you want, and release. In the **Create Block** dialog box, enter a name for the new block. ### Draw a block or element Select **Training Mode** from the **Training** menu. In the **FlexiLayout** window, select a block or a static element. Click the **Draw Location** tool on the toolbar, or select it in **View → Images → Tool**. Place the mouse pointer in the corner of the new block, hold down the left mouse button, drag the corner diagonally in the direction you want, and release. ### Delete a block Click the **Delete Region** tool on the toolbar, or select it in **View → Images → Tool**. Click the block you want to delete. ### Add a rectangular area to a block Click the **Add Region Part** tool on the toolbar, or select it in **View → Images → Tool**. Place the mouse pointer inside the block you want to add a rectangular area to. Hold down the mouse button, drag the pointer diagonally in the direction you want, and release. The rectangle is added to the block. ### Cut out a rectangular area from a block Click the **Cut Region Part** tool on the toolbar, or select it in **View → Images → Tool**. Place the mouse pointer inside the block you want to cut a rectangular area from. Hold down the left mouse button, drag the pointer diagonally in the direction you want, and release. The rectangle is cut from the block. When you cut out top or bottom block areas, the adjoining area on the right, up to the border of the block, is also cut out. This happens because the OCR engine can only recognize continuous text blocks. This constraint does not apply to left-hand and right-hand areas. ### Add a vertical separator Click the **Add Vertical Separator** tool on the toolbar, or select it in **View → Images → Tool**. Rest the mouse pointer over the location you want in the **Table** block. The pointer changes appearance. Click the block. ### Add a horizontal separator Click the **Add Horizontal Separator** tool on the toolbar, or select it in **View → Images → Tool**. Rest the mouse pointer over the location you want in the **Table** block. The pointer changes appearance. Click the block. ### Delete a separator Click the **Delete Separator** tool on the toolbar, or select it in **View → Images → Tool**. Rest the mouse pointer over the location you want in the **Table** block. The pointer changes appearance. Click the block. ### Create a reference layout for Table block columns Click the **Table** block on the image. Use the Add Vertical Separator button, Add Horizontal Separator button, and Delete Separator button tools. Right-click the column and select the column name from the shortcut menu. To delete a column from a **Table** block, right-click the column and select **Delete Column** from the shortcut menu.
