Returns a pointer to an image holding the pattern of the given index. This image should not be modified.

Returns the character code of a given pattern in the current font.

Current pattern width, as set at the last EOCR::NewFont or EOCR::Load operation.
Relative spacing value.
Relative threshold used for image segmentation.
Flag indicating whether all blobs touching the ROI edges are automatically discarded.
Flag indicating whether the characters are discarded when either dimension falls below the minimum value
Returns the code of the pattern that matches at second best a recognized character.
Computes the degree of similarity between the second best matching pattern and a recognized character.
Segmentation mode.
Shifting mode to use to compare characters to the template.
Horizontal translation tolerance around the nominal position when the character positions are explicitly specified.
Vertical translation tolerance around the nominal position when the character positions are explicitly specified.
Text color.
Threshold mode used for image segmentation.
Absolute threshold level when using a single threshold.
Returns true if the cursor is placed over the character specified by charIndex .
Returns true if the cursor is placed over a character and sets the charIndex accordingly.
Adds a new pattern to the font.
Adds all the patterns from the source image to the font.
Reads a single character, i.e. finds the best match between the patterns in the font and the given character.
Empties the contents of the font and sets the size of the pattern array to be used from then on.
Copies all the data from another EOCR object into the current EOCR object
Reads one or more rows of characters, i.e. finds the best match between the patterns in the font and the segmented characters.
DEPRECATED: Use the EOCR::ReadText method instead as it performs similarly to this method, except it returns UTF-8 instead of wide characters. Reads one or more rows of characters, i.e. finds the best match between the patterns in the font and the segmented characters.
Achieves all processing phases (blob analysis, character segmentation and pattern recognition) in a single operation.
