-
-
- PRO-CR(tm) is an Optical Character Recognition program.
-
- A sample image file has been included which you can process now by selecting
- start at the first menu. (Note: this assumes you have not changed any of
- the preset parameters in the options menu!)
-
- The following paragraphs describe how to use the menus, what the status
- line at the bottom of the screen means, and what the options for the top
- level menu are.
-
-
- THE MENU BARS.......Use the arrow keys to select the required option from the
- menu bar and hit return when the option is highlighted. Alternatively, hit
- the highlighted key in the required option to directly select that option.
-
- #
- THE STATUS LINE.....The last line of the screen shows what options you have
- selected and indicates the percentage completion of the current scan:
-
- 0% <ESC=abort> input_file->output_file dpi=200 <PC*> SCANJET
-
- <ESC=abort> indicates that you may hit the Escape key during processing
- to abort the recognition phase.
-
- The next two fields "input_file->output_file" indicate both the source
- of the image to be processed (either from an image file or "SCANNER" if
- from a direct scan) and the output file to receive the processed text.
-
- Next is the resolution in dots per inch. This must be set if scanning
- directly or reading from a PCX file.
-
- Next is a block of 3 parameters inside angle brackets <PC*>. The "P",
- if present, indicates that the image "preview" function is active. The
- "C", if present, indicates that the online correction function is active.
-
- The final character is the "unknown character", i.e. the character to
- output if a mis-recognition occurs.
-
- Finally, the last field indicates the selected scanner type.

-
- TOP LEVEL MENU OPTIONS
-
- Select "Start" to start the recognition process.
-
- Select "Auto" to start recognition using the auto sheet feeder.
- (Note: this option only appears if you are scanning directly and you
- have the HP ScanJet auto sheet feeder attached)
-
- Select "Options" to setup parameters for the recognition process.
- Options that you need to set up are:
- - the source of the image to be processed, either a file or the scanner
- - the resolution of the image in dots per inch (dpi)
-
- Note that the dpi may be automatically available if you are processing a TIFF
- file since the majority of TIFF software includes this. (A warning is given
- for TIFF files that do not provide this). Otherwise, if you are scanning
- directly or reading a PCX file, then you need to set the dpi correctly.
- PRO-CR(tm) has been optimized for the range 200 to 300 dots per inch. (For
- more on setting a suitable dpi, see the manual).
