TessBaseAPIInit1
public static int TessBaseAPIInit1(ITessAPI.TessBaseAPI handle, java.lang.String datapath, java.lang.String language, int oem, com.sun.jna.ptr.PointerByReference configs, int configs_size)
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 useSetVariable
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 beforeInit
are those listed above here in the class definition.
It is entirely safe (and eventually will be efficient too) to callInit
multiple times on the same instance to change language, or just to reset the classifier. Languages may specify internally that they want to be loaded with one or more other languages, so the ~ sign is available to override that. E.g., ifhin
were set to loadeng
by default, thenhin+~eng
would force loading onlyhin
. 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 toInit
you should explicitly callEnd()
and then useSetVariable
beforeInit
.
This is only a very rare use case, since there are very few uses that require any parameters to be set beforeInit
.
Ifset_only_non_debug_params
is true, only params that do not contain "debug" in the name will be set.- Parameters:
handle
- the TesseractAPI instancedatapath
- Thedatapath
must be the name of the parent directory oftessdata
and must end in /. Any name after the last / will be stripped.language
- The language is (usually) anISO 639-3
string orNULL
will default toeng
. The language may be a string of the form [~]<lang>[+[~]<lang>] indicating that multiple languages are to be loaded. E.g.,hin+eng
will load Hindi and English.oem
- ocr engine modeconfigs
- pointer configurationconfigs_size
- pointer configuration size- Returns:
- 0 on success and -1 on initialization failure

Detect the orientation of the input image and apparent script (alphabet).orient_deg
is the detected clockwise rotation of the input image in degrees (0, 90, 180, 270);orient_conf
is the confidence (15.0 is reasonably confident);script_name

is confidence level in the script.- Returns:
- TRUE on success and writes values to each parameter as an output
-
TessBaseAPIGetUnichar

TessPageIteratorBegin

Resets the iterator to point to the start of the page.- Parameters:
handle

-
TessPageIteratorNext
public static int TessPageIteratorNext(ITessAPI.TessPageIterator handle, int level)
Moves to the start of the next object at the given level in the page hierarchy, and returns false if the end of the page was reached. NOTE (CHANGED!) that ALL PageIteratorLevel level values will visit each non-text block at least once.
Think of non text blocks as containing a single para, with at least one line, with a single imaginary word, containing a single symbol. The bounding boxes mark out any polygonal nature of the block, andPTIsTextType(BLockType())
is false for non-text blocks.
Calls to Next with different levels may be freely intermixed. This function iterates words in right-to-left scripts correctly, if the appropriate language has been loaded into Tesseract.- Parameters:
handle
- the TessPageIterator instancelevel
- tesseract page level- Returns:
- next iterator object
-

handle
- the TessPageIterator instancelevel
- tesseract page level- Returns:
- 1 if true
-
TessPageIteratorIsAtFinalElement

handle
- the TessPageIterator instancelevel

TessPageIteratorGetBinaryImage
public static net.sourceforge.lept4j.Pix TessPageIteratorGetBinaryImage(ITessAPI.TessPageIterator handle, int level)
Returns a binary image of the current object at the given level. The position and size match the return from BoundingBoxInternal, and so this could be upscaled with respect to the original input image. UsepixDestroy
to delete the image after use. The following methods are used to generate the images:RIL_BLOCK
: mask the page image with the block polygon.RIL_TEXTLINE
: Clip the rectangle of the line box from the page image. TODO(rays) fix this to generate and use a line polygon.RIL_WORD
: Clip the rectangle of the word box from the page image.RIL_SYMBOL
: Render the symbol outline to an image for cblobs (prior to recognition) or the bounding box otherwise. A reconstruction of the original image (using xor to check for double representation) should be reasonably accurate, apart from removed noise, at the block level. Below the block level, the reconstruction will be missing images and line separators. At the symbol level, kerned characters will be invade the bounding box if rendered after recognition, making an xor reconstruction inaccurate, but an or construction better. Before recognition, symbol-level reconstruction should be good, even with xor, since the images come from the connected components.- Parameters:
handle
- the TessPageIterator instancelevel
- PageIteratorLevel- Returns:
-
TessPageIteratorGetImage
public static net.sourceforge.lept4j.Pix TessPageIteratorGetImage(ITessAPI.TessPageIterator handle, int level, int padding, net.sourceforge.lept4j.Pix original_image, java.nio.IntBuffer left, java.nio.IntBuffer top)
Returns an image of the current object at the given level in greyscale if available in the input. To guarantee a binary image use BinaryImage. NOTE that in order to give the best possible image, the bounds are expanded slightly over the binary connected component, by the supplied padding, so the top-left position of the returned image is returned in (left,top). These will most likely not match the coordinates returned by BoundingBox. If you do not supply an original image, you will get a binary one. UsepixDestroy
to delete the image after use.- Parameters:
handle
- the TessPageIterator instancelevel
- PageIteratorLevelpadding
-original_image
-left
-top
-- Returns:
-
