Raster To Text
This command will create text from an image in your drawing
generated from commands such as PDF Import, Raster Import, Attach
Image, etc. one line at a time. From the OCR (Optical Character
Recognition) Options dialog, you have the ability to identify
the Background and Text Color of the image being used. The Text
Layer and the font Style the text will appear on once converted can
also be set here.
Perform Numeric OCR will limit the text recognition to only
numeric values. By default, this command attempts to convert to
alphabetic characters as well. When dealing with only numeric text,
turn this feature on so that no alphabetic characters are
accidentally used during the conversion. Use the Match Prefix or
Match Suffix to help the recognition when the numbers have an alpha
prefix or suffix like "TC 123.4".
The Overwrite Image option will erase the raster text from
the image after it has been converted to CAD text.
The Leader Line option draws a leader along with converting
the text.
For the OCR Mode, the Standard Mode prompts to pick two
points across the raster text for each text to convert. These
points define the area of the image to process. The One Click
Mode converts the first text like Standard Mode and gets the
text size and angle properties from this first text. Then for the
additional text to convert, you only need to pick a single point on
the text instead of two points. For the Area Search Mode,
the first text is again processed the same as Standard Mode and
then you window an area and the program looks for other raster text
with the same size and angle as the first text.
The Prompt Before Placing Text shows the conversion results
in a dialog with a chance to review, edit or cancel.
After clicking OK to the OCR Options dialog, you will be prompted
for a "start of strike-line" then "end of strike-line". Pick left
to right through the text you want to convert. A Replacement
Text dialog will appear. Here you can review the values that
the program has converted and change them if needed before
accepting them by clicking OK. You will then be prompted to
"strike-through" another line of text. Press Enter to end.
