OCRX_get_utf8_text

Gets the size, in bytes, of the text contained by a given result in UTF-8 format.

A byte for null termination is included in the size calculation.

Arguments:

Name	Type	Description
result	const OCRX_Result	Result for which to get the text size.
textSize	int32_t*	Size of the text; in bytes.

Return Value:

OCRX_Status – Specifies whether an error occurred and, if so, specifies which error and any relevant details.

Example:

	Copy Code
#include “ocrxpress.h” intptr_t dib = 0; OCRX_RecognitionParameters params = OCRX_DefaultRecognitionParameters; OCRX_Result documentResult = 0; int32_t textBufferSize = 0; OCRX_set_solution_name(“solutionName”); OCRX_set_solution_key(0x00000001, 0x00000002, 0x00000003, 0x00000004); OCRX_set_oem_license_key(“oemLicenseKey”); OCRX_load_file(“/home/user/image.bmp”, &dib); OCRX_recognize_to_memory(params, dib, &documentResult); OCRX_free_dib(dib); OCRX_get_utf8_text_size(documentResult, &textBufferSize); OCRX_free_document_result(&documentResult);

Copy Code

#include “ocrxpress.h”

intptr_t dib = 0;
OCRX_RecognitionParameters params = OCRX_DefaultRecognitionParameters;
OCRX_Result documentResult = 0;
int32_t textBufferSize = 0;

OCRX_set_solution_name(“solutionName”);
OCRX_set_solution_key(0x00000001, 0x00000002, 0x00000003, 0x00000004);
OCRX_set_oem_license_key(“oemLicenseKey”);

OCRX_load_file(“/home/user/image.bmp”, &dib);
OCRX_recognize_to_memory(params, dib, &documentResult);
OCRX_free_dib(dib);
OCRX_get_utf8_text_size(documentResult, &textBufferSize);
OCRX_free_document_result(&documentResult);
