<title>Manual Edition</title>
<p>One may want to manually select just a portion of an image to
be recognized or correct the results of the automatic recognition.
<app>OCRFeeder</app> lets its users manually edit every aspect of
a document's contents in an easy way.</p>
<section id="content-areas">
<title>Content Areas</title>
<p>The mentioned document's contents are represented by areas like
shown in the following image:</p>
<media type="image" mime="image/png" src="figures/content-areas.png"
width="300px">
<p>A picture of two content areas with one of them selected.</p>
</media>
<p>The attributes of a selected are shown and can be changed from
the right part of the main window, like shown in the following image:
</p>
<media type="image" mime="image/png" src="figures/areas-edition.png" width="200px"><p>A
picture showing the areas' edition UI</p></media>
<p>The following list describes the content areas' attributes:</p>
<list>
<item><p><em>Type</em>: sets the area to be either the type image or text.
The image type will clip the area from the original page and
place it in the generated document. The text type will use the
text assigned to the area and represent it as text in the generated
document. (Generated ODT documents will have text boxes when an
area was marked as being of the type text)</p></item>
<item><p><em>Clip</em>: Shows the current clip from the original area. This makes
it easier for users to check exactly what's within the area.</p></item>
<item><p><em>Bounds</em>: Shows the point (X and Y) in the original image where the
top left corner of the area is placed as well as the areas' width
and height.</p></item>
<item><p><em>OCR Engine</em>: Lets the user choose an OCR engine and recognize the
area's text with by (by pressing the <gui>OCR</gui> button).</p>
<note style="warning"><p>Using the OCR engine to recognize the text
will directly assign that text to the area and replace the one
assigned before.</p></note></item>
<item><p><em>Text Area</em>: Represents the text assigned to that area and lets the
user edit it. This area is disabled when the area is of the type
image</p></item>
<item><p><em>Style Tab</em>: Lets the user choose the font type and size, as well as
the text alignment, line and letter spacing.</p></item>
</list>
<p>The content areas can be selected by clicking on them or by using the menus
<guiseq><gui>Document</gui><gui>Select Previous Area</gui></guiseq> and
<guiseq><gui>Document</gui><gui>Select Next Area</gui></guiseq>. There are
also keyboard shortcuts for these actions:
<keyseq><key>Ctrl</key><key>Shift</key><key>P</key></keyseq> and
<keyseq><key>Ctrl</key><key>Shift</key><key>N</key></keyseq>, respectively.</p>
<p>Selecting all areas is also possible using
<guiseq><gui>Document</gui><gui>Select All Areas</gui></guiseq> or
<keyseq><key>Ctrl</key><key>Shift</key><key>A</key></keyseq>.</p>
<p>When at least one content area is selected, it is possible to recognize
their contents automatically or delete them. These actions can be accomplished
by clicking <guiseq><gui>Document</gui><gui>Recognized Selected Areas</gui></guiseq>
and <guiseq><gui>Document</gui><gui>Delete Selected Areas</gui></guiseq> (or
