C#һәм .NET

Updated: July 21, 2026

Бу документның башка версияләре:

IronOCR - C# программа компоненты .NET кодераторларына рәсемнәрдән һәм PDF документларыннан текстны 126 телдә укырга мөмкинлек бирә, шул исәптән татар.

Бу Тессерактның алдынгы челтәре, .NET ясаучылар өчен генә төзелгән һәм тизлек һәм төгәллек өчен башка Tesseract двигательләреннән даими узып бара.

IronOcr.Languages.Tatar эчтәлеге

Бу пакетта .NET өчен 40 OCR теле бар:

Татар
TatarBest
Tatarәр сүзнең

Йөкләү

Татар Pack [татар теле Себер теле]
* Download as Почта
* Install with NuGet

Урнаштыру

Беренче эш - безнең .NET проектына безнең Татар OCR пакетын урнаштыру.

PM> Install-Package IronOcr.Languages.Tatar

Код үрнәге

Бу C# код мисалы Рәсем яки PDF документыннан татар текстын укый.

// PM> Install-Package IronOcr.Languages.Tatar
using IronOcr;

// Create an OCR engine instance and set the language to Tatar
var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Tatar;

// Load the input image
using (var Input = new OcrInput(@"images\Tatar.png"))
{
    // Process the input image and extract text
    var Result = Ocr.Read(Input);
    
    // Store the recognized text in a variable
    var AllText = Result.Text;
}

// PM> Install-Package IronOcr.Languages.Tatar
using IronOcr;

// Create an OCR engine instance and set the language to Tatar
var Ocr = new IronTesseract();
Ocr.Language = OcrLanguage.Tatar;

// Load the input image

Нигә IronOCR сайларга?

Тимер OCR - урнаштыру җиңел, тулы һәм яхшы документлаштырылган .NET программа китапханәсе.

Тышкы веб-хезмәтләрне, дәвамлы түләүләрне кулланмыйча яки интернет аша яшерен документлар җибәрмичә, 99,8% + OCR төгәллегенә ирешү өчен IronOCR-ны сайлагыз.

Ни өчен C# уйлап табучылар Vanilla Tesseract өстендә IronOCR сайлыйлар:

Бер DLL яки NuGet итеп урнаштырыгыз
Тессеракт өчен 5, 4 һәм 3 двигательләр керә.
Төгәллек 99,8% регуляр Тессеракттан күпкә өстен.
Ялкынлы тизлек һәм күп уку
MVC, WebApp, Desktop, Console & Server кушымтасы туры килә
Эшләргә Exes яки C ++ коды юк
Тулы PDF OCR ярдәме
OCR теләсә нинди Рәсем файлын яки PDFны башкару өчен
Тулы .NET Core, Standard һәм FrameWork ярдәме
Windows, Mac, Linux, Azure, Docker, Lambda, AWS урнаштырыгыз
Штрих-кодларны һәм QR кодларны укыгыз
XHTML буенча OCR экспортлагыз
Эзләнә торган PDF документларына OCR экспортлагыз
Күпкырлы ярдәм
126 халыкара тел барысы да NuGet яки OcrData файллары белән идарә ителә
Рәсемнәрне, координаталарны, статистика һәм шрифтларны чыгару. Текст кына түгел.
Tesseract OCR-ны коммерция һәм милек кушымталары эчендә тарату өчен кулланырга мөмкин.

Тимер OCR реаль дөнья образлары һәм камил булмаган документлар белән эшләгәндә балкып тора, фотосурәтләр, яки санлы тавыш яки кимчелекләр булырга мөмкин түбән резолюция сканерлары.

.NET платформасы өчен бүтән бушлай OCR китапханәләре, башка .NET Tesseract APIs һәм веб-хезмәтләр бу реаль дөнья куллану очракларында бик яхшы эшләми.

OCR Рәсем Фильтрлары исемлеге

IronOCR эчендә төзелгән OCR җитештерүчәнлеген арттыру өчен кертү фильтрлары:

OcrInput.Rotate(double degrees) - Rotate images clockwise by a specified number of degrees. Use negative numbers for counter-clockwise rotation.
OcrInput.Binarize() - Converts each pixel in the image to black or white. This filter can improve OCR outcomes when there is very low contrast between text and background.
OcrInput.ToGrayScale() - Converts each pixel into a shade of gray. This may not improve OCR accuracy but can improve processing speed.
OcrInput.Contrast() - Automatically enhances image contrast. This filter often improves both the speed and accuracy of OCR on low-contrast documents.
OcrInput.DeNoise() - Removes digital noise. Use this filter only when noise is present.
OcrInput.Invert() - Inverts all colors. For example, black becomes white, and white becomes black.
OcrInput.Dilate() - Advanced morphology operation. Dilation adds pixels to the boundaries of objects in an image. Opposite of erosion.
OcrInput.Erode() - Advanced morphology operation. Erosion removes pixels on object boundaries.
OcrInput.Deskew() - Corrects image rotation so that it is upright and orthogonal. This is highly beneficial for OCR as Tesseract's tolerance for skew is low, around 5 degrees.
OcrInput.DeepCleanBackgroundNoise() - Severe background noise removal. Apply this filter when extreme document background noise is known; it can reduce OCR accuracy on clean documents and is CPU intensive.
OcrInput.EnhanceResolution - Augments resolution of low-quality images. Often unnecessary because OcrInput.MinimumDPI and OcrInput.TargetDPI will automatically detect and correct low-resolution inputs.

CleanBackgroundNoise - This setting requires significant computation time; however, it allows the library to automatically clean up digital noise, paper artifacts, and other imperfections, making it readable by other OCR libraries.

EnhanceContrast - This configuration automatically increases the contrast between text and its background, increasing OCR accuracy and typically boosting performance and speed.

EnhanceResolution - This setting will detect low-resolution images (below 275 dpi) and upscale them so they are more readable by the OCR library, shortening overall OCR operation time for low-quality inputs.

Language - IronOCR supports 22 international language packs, allowing the selection of one or more languages to use in the OCR operation.

Strategy - IronOCR supports two strategies: a faster, less accurate scan, and a more advanced strategy using artificial intelligence models to automatically improve text accuracy.

ColorSpace - Determines whether OCR uses grayscale or color. Grayscale is usually the best choice, but full color may yield better results when there is similar colored text or background in full-text color space.

DetectWhiteTextOnDarkBackgrounds - By default, OCR libraries will recognize black text on white backgrounds. This configuration allows IronOCR to automatically detect and read white text on black backgrounds.

InputImageType - Provides guidance to the OCR library as to whether the input is expected to be a full document or a snippet like a screenshot.

RotateAndStraighten - An advanced setting that allows IronOCR to not just rotate but correct perspectives found in photographs of text documents.

ReadBarcodes - This feature allows IronOCR to automatically read barcodes and QR codes as it reads text, adding little additional processing time.

ColorDepth - Determines the bit depth used per pixel by the OCR library for color, which may increase OCR quality but also the processing time required to complete an OCR operation.
