```
public void SetInputName(@Cast(value="const char*")
                         org.bytedeco.javacpp.BytePointer name)
```
Set the name of the input file. Needed for training and reading a UNLV zone file, and for searchable PDF output.

These functions are required for searchable PDF output. We need our hands on the input file so that we can include it in the PDF without transcoding. If that is not possible, we need the original image. Finally, resolution metadata is stored in the PDF so we need that as well.

```
Set the value of an internal "parameter." Supply the name of the parameter and the value as a string, just as you would in a config file. Returns false if the name lookup failed. Eg SetVariable("tessedit_char_blacklist", "xyz"); to ignore x, y and z. Or SetVariable("classify_bln_numeric_mode", "1"); to set numeric-only mode. SetVariable may be used before Init, but settings will revert to defaults on End(). Note: Must be called after Init(). Only works for non-init variables (init variables should be passed to Init()).

Instances are now mostly thread-safe and totally independent, but some global parameters remain. Basically it is safe to use multiple TessBaseAPIs in different threads in parallel, UNLESS: you use SetVariable on some of the Params in classify and textord. If you do, then the effect will be to change it for all your instances. Start tesseract. Returns zero on success and -1 on failure. NOTE that the only members that may be called before Init are those listed above here in the class definition. The datapath must be the name of the parent directory of tessdata and must end in / . Any name after the last / will be stripped. The language is (usually) an ISO 639-3 string or nullptr will default to eng. It is entirely safe (and eventually will be efficient too) to call Init multiple times on the same instance to change language, or just to reset the classifier. The language may be a string of the form [~][+[~]]* indicating that multiple languages are to be loaded. Eg hin+eng will load Hindi and English. Languages may specify internally that they want to be loaded with one or more other languages, so the ~ sign is available to override that. Eg if hin were set to load eng by default, then hin+~eng would force loading only hin. The number of loaded languages is limited only by memory, with the caveat that loading additional languages will impact both speed and accuracy, as there is more work to do to decide on the applicable language, and there is more chance of hallucinating incorrect words. WARNING: On changing languages, all Tesseract parameters are reset back to their default values. (Which may vary between languages.) If you have a rare need to set a Variable that controls initialization for a second call to Init you should explicitly call End() and then use SetVariable before Init. This is only a very rare use case, since there are very few uses that require any parameters to be set before Init. If set_only_non_debug_params is true, only params that do not contain "debug" in the name will be set.

```
@Cast(value="const char*")
public org.bytedeco.javacpp.BytePointer GetInitLanguagesAsString()
```
Returns the languages string used in the last valid initialization. If the last initialization specified "deu+hin" then that will be returned. If hin loaded eng automatically as well, then that will not be included in this list. To find the languages actually loaded use GetLoadedLanguagesAsVector. The returned string should NOT be deleted.

GetLoadedLanguagesAsVector
```
public void GetLoadedLanguagesAsVector(tesseract.StringGenericVector langs)
```
Returns the loaded languages in the vector of STRINGs. Includes all languages loaded by the last Init, including those loaded as dependencies of other loaded languages.

GetAvailableLanguagesAsVector
```
public void GetAvailableLanguagesAsVector(tesseract.StringGenericVector langs)
```
Returns the available languages in the vector of STRINGs.

InitForAnalysePage
```
public void InitForAnalysePage()
```
Init only for page layout analysis. Use only for calls to SetImage and AnalysePage. Calls that attempt recognition will generate an error.

ReadConfigFile
```
public void ReadConfigFile(@Cast(value="const char*")
                           org.bytedeco.javacpp.BytePointer filename)
```
Read a "config" file containing a set of param, value pairs. Searches the standard places: tessdata/configs, tessdata/tessconfigs and also accepts a relative or absolute path name. Note: only non-init params will be set (init params are set by Init()).

ReadConfigFile

public void ReadConfigFile(String filename)

ReadDebugConfigFile

public void ReadDebugConfigFile(@Cast(value="const char*")
                                org.bytedeco.javacpp.BytePointer filename)

Same as above, but only set debug params from the given config file.

ReadDebugConfigFile

public void ReadDebugConfigFile(String filename)

SetPageSegMode
```
public void SetPageSegMode(@Cast(value="tesseract::PageSegMode")
                           int mode)
```
Set the current page segmentation mode. Defaults to PSM_SINGLE_BLOCK. The mode is stored as an IntParam so it can also be modified by ReadConfigFile or SetVariable("tessedit_pageseg_mode", mode as string).

GetPageSegMode

@Cast(value="tesseract::PageSegMode")
public int GetPageSegMode()

Return the current page segmentation mode.

TesseractRect

                                                                            int height)
```
Recognize a rectangle from an image and return the result as a string. May be called many times for a single Init. Currently has no error checking. Greyscale of 8 and color of 24 or 32 bits per pixel may be given. Palette color images will not work properly and must be converted to 24 bit. Binary images of 1 bit per pixel may also be given but they must be byte packed with the MSB of the first byte being the first pixel, and a 1 represents WHITE. For binary images set bytes_per_pixel=0. The recognized text is returned as a char* which is coded as UTF8 and must be freed with the delete [] operator. Note that TesseractRect is the simplified convenience interface. For advanced uses, use SetImage, (optionally) SetRectangle, Recognize, and one or more of the Get*Text functions below.

TesseractRect

@Cast(value="char*")
public ByteBuffer TesseractRect(@Cast(value="const unsigned char*")
                                                      ByteBuffer imagedata,
                                                      int bytes_per_pixel,
                                                      int bytes_per_line,
                                                      int left,
                                                      int top,

                                                      int height)

TesseractRect

@Cast(value="char*")
public byte[] TesseractRect(@Cast(value="const unsigned char*")
                                                  byte[] imagedata,
                                                  int bytes_per_pixel,
                                                  int bytes_per_line,
                                                  int left,
                                                  int top,
                                                  int width,
                                                  int height)

ClearAdaptiveClassifier
```
public void ClearAdaptiveClassifier()
```
Call between pages or documents etc to free up memory and forget adaptive data.

SetImage
```
public void SetImage(@Cast(value="const unsigned char*")
                     org.bytedeco.javacpp.BytePointer imagedata,
                     int width,
                     int height,
                     int bytes_per_pixel,
                     int bytes_per_line)
```
Provide an image for Tesseract to recognize. Format is as TesseractRect above. Copies the image buffer and converts to Pix. SetImage clears all recognition results, and sets the rectangle to the full image, so it may be followed immediately by a GetUTF8Text, and it will automatically perform recognition.

SetImage

public void SetImage(@Cast(value="const unsigned char*")
                     ByteBuffer imagedata,
                     int width,
                     int height,
                     int bytes_per_pixel,
                     int bytes_per_line)

SetImage

public void SetImage(@Cast(value="const unsigned char*")
                     byte[] imagedata,
                     int width,
                     int height,
                     int bytes_per_pixel,
                     int bytes_per_line)

SetImage
```
public void SetImage(org.bytedeco.javacpp.lept.PIX pix)
```
Provide an image for Tesseract to recognize. As with SetImage above, Tesseract takes its own copy of the image, so it need not persist until after Recognize. Pix vs raw, which to use? Use Pix where possible. Tesseract uses Pix as its internal representation and it is therefore more efficient to provide a Pix directly.

SetSourceResolution
```
public void SetSourceResolution(int ppi)
```
Set the resolution of the source image in pixels per inch so font size information can be calculated in results. Call this after SetImage().

SetRectangle
```
public void SetRectangle(int left,
                         int top,
                         int width,
                         int height)
```
Restrict recognition to a sub-rectangle of the image. Call after SetImage. Each SetRectangle clears the recogntion results so multiple rectangles can be recognized with the same image.

SetThresholder
```
public void SetThresholder(tesseract.ImageThresholder thresholder)
```
In extreme cases only, usually with a subclass of Thresholder, it is possible to provide a different Thresholder. The Thresholder may be preloaded with an image, settings etc, or they may be set after. Note that Tesseract takes ownership of the Thresholder and will delete it when it it is replaced or the API is destructed.

GetThresholdedImage
```
public org.bytedeco.javacpp.lept.PIX GetThresholdedImage()
```
Get a copy of the internal thresholded image from Tesseract. Caller takes ownership of the Pix and must pixDestroy it. May be called any time after SetImage, or after TesseractRect.

GetRegions

public org.bytedeco.javacpp.lept.BOXA GetRegions(@Cast(value="Pixa**")
                                                 org.bytedeco.javacpp.PointerPointer pixa)

                                                   boolean raw_image,
                                                   int raw_padding,
                                                   @Cast(value="Pixa**")
                                                   org.bytedeco.javacpp.PointerPointer pixa,
                                                   @Cast(value="int**")
                                                   org.bytedeco.javacpp.PointerPointer blockids,
                                                   @Cast(value="int**")
                                                   org.bytedeco.javacpp.PointerPointer paraids)

Get the textlines as a leptonica-style Boxa, Pixa pair, in reading order. Can be called before or after Recognize. If raw_image is true, then extract from the original image instead of the thresholded image and pad by raw_padding pixels. If blockids is not nullptr, the block-id of each line is also returned as an array of one element per line. delete [] after use. If paraids is not nullptr, the paragraph-id of each line within its block is also returned as an array of one element per line. delete [] after use.

Get the given level kind of components (block, textline, word etc.) as a leptonica-style Boxa, Pixa pair, in reading order. Can be called before or after Recognize. If blockids is not nullptr, the block-id of each component is also returned as an array of one element per component. delete [] after use. If blockids is not nullptr, the paragraph-id of each component with its block is also returned as an array of one element per component. delete [] after use. If raw_image is true, then portions of the original image are extracted instead of the thresholded image and padded with raw_padding. If text_only is true, then only text components are returned.

GetThresholdedImageScaleFactor
```
public int GetThresholdedImageScaleFactor()

Returns the scale factor of the thresholded image that would be returned by GetThresholdedImage() and the various GetX() methods that call GetComponentImages(). Returns 0 if no thresholder has been set.

AnalyseLayout
```
public tesseract.PageIterator AnalyseLayout()
```
Runs page layout analysis in the mode set by SetPageSegMode. May optionally be called prior to Recognize to get access to just the page layout results. Returns an iterator to the results. If merge_similar_words is true, words are combined where suitable for use with a line recognizer. Use if you want to use AnalyseLayout to find the textlines, and then want to process textline fragments with an external line recognizer. Returns nullptr on error or an empty page. The returned iterator must be deleted after use. WARNING! This class points to data held within the TessBaseAPI class, and therefore can only be used while the TessBaseAPI class still exists and has not been subjected to a call of Init, SetImage, Recognize, Clear, End DetectOS, or anything else that changes the internal PAGE_RES.

Turns images into symbolic text. filename can point to a single image, a multi-page TIFF, or a plain text list of image filenames. retry_config is useful for debugging. If not nullptr, you can fall back to an alternate configuration if a page fails for some reason. timeout_millisec terminates processing if any single page takes too long. Set to 0 for unlimited time. renderer is responible for creating the output. For example, use the TessTextRenderer if you want plaintext output, or the TessPDFRender to produce searchable PDF. If tessedit_page_number is non-negative, will only process that single page. Works for multi-page tiff file, or filelist. Returns true if successful, false on error.

```
Applies the given word to the adaptive classifier if possible. The word must be SPACE-DELIMITED UTF-8 - l i k e t h i s , so it can tell the boundaries of the graphemes. Assumes that SetImage/SetRectangle have been used to set the image to the given word. The mode arg should be PSM_SINGLE_WORD or PSM_CIRCLE_WORD, as that will be used to control layout analysis. The currently set PageSegMode is preserved. Returns false if adaption was not possible for some reason.

Free up recognition results and any stored image data, without actually freeing any recognition data that would be time-consuming to reload. Afterwards, you must call SetImage or TesseractRect before doing any Recognize or Get* operation.

End
```
public void End()
```
Close down tesseract and free up all memory. End() is equivalent to destructing and reconstructing your TessBaseAPI. Once End() has been used, none of the other API functions may be used other than Init and anything declared above it in the class definition.

ClearPersistentCache
```
public static void ClearPersistentCache()
```
Clear any library-level memory caches. There are a variety of expensive-to-load constant data structures (mostly language dictionaries) that are cached globally -- surviving the Init() and End() of individual TessBaseAPI's. This function allows the clearing of these caches.
