Sequence:
This feature is like the feature launched by the '>>' icon button in the icon
tool bar. Its tool tip reads, "
Display each selected image in turn in the text cropping dialog
and store its cropped text in the CropLog table." (The
status line at the bottom also shows help for each menu item and
button.) The only difference is that it will only display
the image files in the list that have been checked.
Selecting them using the mouse on the file path itself will not
include them.
Batch:
Like the "Sequence" feature in the same menu, this will operate
on all files in the image file list that are selected using the
checkbox. The difference is that it will extract all of the
text from each in turn without showing a dialog and will store the
extracted text in a record in the BatchMaster table in the
TextExtraction.db database. The file's path is one of the
fields stored, but since it is not the key field, multiple
extractions from the same file will have separate records with
different time stamps. This allows you to check for
modifications of image files over time, such a might occur if
there is tampering with them. The fields stored in the
record include the time-stamp of the extraction process, the full
file path, the text extracted, and in the info field the 'stat' of
the file at the time the text was extracted. This is simply
the file meta-data available from the operating system, which
includes such items as the last modified time-stamp, the file
size, and the access restrictions.
An alternative is to use the button on the icon tool bar with the circular arrow icon and the help text, "Extract all text from all files in the list and store it in the BatchMaster table ." This ignores both the check boxes and any list selections you might have made and simply extracts all text from all of the files in the list. This should be used with caution as depending on the number of files in the list, this could take a long time. Basic progress will be displayed on in the console. For more detailed and complete reporting, use the Jobs definition and running features.
Job:
Use this feature to select and run a job that you defined using
the Admin -> Jobs main menu selection or the toolbox icon
button in the icon tool bar. These launch the "Job
Definition" dialog in which you can select files and folders to
include in any order in a sequence or batch and then save the job
for use later under a name you provide. You cash also
specify a job type, although this feature is not yet developed to
the point where a list of already entered job types are displayed
for your selection in this dialog. Once you have reviewed the help
on how to define a job, come back to this page to see how one is
run.
When you select this menu item, a dialog with the title "Select
and RUN Job" will be launched. It displays a list of the
names of jobs that you have defined from which you can select one
to run. There are two modes in which you can run a
job: Sequence, and Batch. These work like the Sequence
and Batch selections previously described for this Run menu
(above). Batch mode has an additional feature
available. If you select Batch from the menu button labelled
"Run Mode:" at the top, A help message displays at the bottom
along with a Console Output configuration panel. Since Batch
Jobs can take significant time to run, you can select the items
you want displayed as each file is processed by the text
extraction engine. Selecting "File Path" will provide s
count of the files processed along with the full path of each file
as it is processed. Selecting "Times and Durations" will
also display the start and end time for each file along with the
time it took to extract the text. This also provides the
start and end times for the entire batch and its duration.
Choosing "Statistics" only provides the byte count of the text
extracted currently, although more is possible in the future
depending on interest. Selecting "Text Extracted" should be
used with caution since it will cause the entire text extracted to
be written go the console after the other items selected have been
displayed.
Like the rest of the application, all of the buttons and other
controls have brief help displayed in their tool tips and at the
same time in the status bar at the bottom.
