2. Position the mouse at the point where you want a corner of your block to be. Hold down
the left mouse button and drag the mouse pointer to the point where you want the
opposite block corner to be.
3. Release the mouse button.
A frame will enclose the image area selected.
You may then change the block type. The drawn block type may be one of the following:
Recognition
Area, Text, Table, Picture, or Barcode. To change block type:
● Right-click the block and select the Block Type item followed by the corresponding block
type in the local menu.
Modifying blocks
To move the block borders:
1. Click the block border and hold down the left mouse button. The mouse pointer will
become a two-headed arrow.
2. Drag the pointer in the direction you need.
3. Release the mouse button.
Note: If you click a block corner, you can move both the horizontal and vertical borders of the block
at the same time.
To add a rectangular block part:
1. Select the tool.
2. Click the block you wish to add a part to. Press and hold down the left mouse button then
drag the mouse pointer diagonally. Select the image area you wish added to the block and
release the button. The rectangle drawn will be added to the block.
3. If necessary, move the block border.
To cut a rectangular block part:
1. Select the tool.
2. Click the block you wish to cut a part from. Press and hold down the left mouse button
then drag the mouse pointer diagonally. Select the image area you want cut and release the
button. The selected rectangle will be cut from the block.
3. If necessary, move the block border.
Note:
1. You can alter block borders by adding new nodes (splitting points) to them. Use the mouse
to move segments in any direction you desire. To add a new node, press Shift then move
the mouse pointer to the point where you wish a new node to be created (the pointer will
become a cross) and click on the border. A new node will be created.
2. FineReader imposes certain requirements on block form. These requirements exist as text
lines within blocks must be unbroken if recognition is to be successful. To ensure that these
requirements are met, FineReader automatically corrects block borders when parts are
added or cut. For example, if you cut a part off the top or bottom of a block, a whole block
corner will automatically be cut. Similarly, if you try to cut off a part between the two upper
or lower corners, the application will cut the right block corner (upper or lower) regardless.
It will also forbid certain operations if they involve moving the segments forming the block
borders.
