get_text_objectT_get_text_objectGetTextObjectGetTextObjectget_text_object (Operator)

Name

get_text_objectT_get_text_objectGetTextObjectGetTextObjectget_text_object — Query an iconic value of a text segmentation result.

Signature

get_text_object( : Characters : TextResultID, ResultName : )

Description

get_text_objectget_text_objectGetTextObjectGetTextObjectget_text_object queries the iconic result ResultNameResultNameResultNameresultNameresult_name of TextResultIDTextResultIDTextResultIDtextResultIDtext_result_id returned by find_textfind_textFindTextFindTextfind_text. The possible parameter values for ResultNameResultNameResultNameresultNameresult_name differ, depending on the text model used within the text segmentation process of find_textfind_textFindTextFindTextfind_text.

In the following, first the possible parameter values for text models with ModeModeModemodemode = 'auto'"auto""auto""auto""auto" are listed, and then those for text models with ModeModeModemodemode = 'manual'"manual""manual""manual""manual".

The following results can be queried:

Result objects for text segmentation with text models with ModeModeModemodemode = 'auto'"auto""auto""auto""auto"

For each polarity, the text lines are independently sorted from top to bottom and left to right. The character within the text lines are sorted from left to right.

'all_lines'"all_lines""all_lines""all_lines""all_lines":

Returns all characters in all segmented text lines.

['line', LineIndex]["line", LineIndex]["line", LineIndex]["line", LineIndex]["line", LineIndex]:

Returns all characters within the text line specified by LineIndex. For example, ['line', 0]["line", 0]["line", 0]["line", 0]["line", 0] returns the first line.

['element', Index]["element", Index]["element", Index]["element", Index]["element", Index]:

Returns the character at position Index. For example, ['element', 0]["element", 0]["element", 0]["element", 0]["element", 0] returns the first character.
Result objects for text segmentation with text models with ModeModeModemodemode = 'manual'"manual""manual""manual""manual"

'manual_all_lines'"manual_all_lines""manual_all_lines""manual_all_lines""manual_all_lines":

Returns all characters in all segmented text lines. The text lines are sorted from top to bottom and left to right. The characters within the text lines are sorted from left to right.

['manual_line', Index]["manual_line", Index]["manual_line", Index]["manual_line", Index]["manual_line", Index]:

Returns all characters within the text line specified by Index (e.g., ['manual_line',0]["manual_line",0]["manual_line",0]["manual_line",0]["manual_line",0] to return the first line). The characters within the text line are sorted from left to right.

If 'manual_persistence'"manual_persistence""manual_persistence""manual_persistence""manual_persistence" was activated for the text model used to create TextResultIDTextResultIDTextResultIDtextResultIDtext_result_id, the following additional value can be queried:

'manual_compensated_image'"manual_compensated_image""manual_compensated_image""manual_compensated_image""manual_compensated_image":

the enhanced image used for segmentation.

Example (HDevelop)

read_image (Image, 'numbers_scale')
create_text_model_reader ('auto', 'Document_Rej.omc', TextModel)
* Optionally specify text properties
set_text_model_param (TextModel, 'min_char_height', 20)
find_text (Image, TextModel, TextResultID)
* Return character regions and corresponding classification results
get_text_object (Characters, TextResultID, 'all_lines')
get_text_result (TextResultID, 'class', Class)

Result

If the parameters are valid, the operator get_text_objectget_text_objectGetTextObjectGetTextObjectget_text_object returns the value 2 ( H_MSG_TRUE) . If necessary, an exception is raised.
