Class tesseract.ImageThresholder

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.tesseract.ImageThresholder

All Implemented Interfaces:

AutoCloseable

Enclosing class:

tesseract

@Namespace(value="tesseract")
 @NoOffset
public static class tesseract.ImageThresholder
extends org.bytedeco.javacpp.Pointer

Base class for all tesseract image thresholding classes. Specific classes can add new thresholding methods by overriding ThresholdToPix. Each instance deals with a single image, but the design is intended to be useful for multiple calls to SetRectangle and ThresholdTo* if desired.

Constructor Detail

ImageThresholder

public ImageThresholder(org.bytedeco.javacpp.Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

Clear

public void Clear()

Destroy the Pix if there is one, freeing memory.

GetImageSizes

public void GetImageSizes(org.bytedeco.javacpp.IntPointer left,
                          org.bytedeco.javacpp.IntPointer top,
                          org.bytedeco.javacpp.IntPointer width,
                          org.bytedeco.javacpp.IntPointer height,
                          org.bytedeco.javacpp.IntPointer imagewidth,
                          org.bytedeco.javacpp.IntPointer imageheight)

Get enough parameters to be able to rebuild bounding boxes in the original image (not just within the rectangle). Left and top are enough with top-down coordinates, but the height of the rectangle and the image are needed for bottom-up.

GetImageSizes

public void GetImageSizes(IntBuffer left,
                          IntBuffer top,
                          IntBuffer width,
                          IntBuffer height,
                          IntBuffer imagewidth,
                          IntBuffer imageheight)

GetImageSizes

public void GetImageSizes(int[] left,
                          int[] top,
                          int[] width,
                          int[] height,
                          int[] imagewidth,
                          int[] imageheight)

IsColor

@Cast(value="bool")
public boolean IsColor()

Return true if the source image is color.

IsBinary

@Cast(value="bool")
public boolean IsBinary()

Returns true if the source image is binary.

GetScaleFactor

public int GetScaleFactor()

SetSourceYResolution

public void SetSourceYResolution(int ppi)

GetSourceYResolution

public int GetSourceYResolution()

GetScaledYResolution

public int GetScaledYResolution()

SetEstimatedResolution

public void SetEstimatedResolution(int ppi)

GetScaledEstimatedResolution

public int GetScaledEstimatedResolution()

ThresholdToPix

@Cast(value="bool")
public boolean ThresholdToPix(@Cast(value="tesseract::PageSegMode")
                                                   int pageseg_mode,
                                                   @Cast(value="Pix**")
                                                   org.bytedeco.javacpp.PointerPointer pix)

Threshold the source image as efficiently as possible to the output Pix. Creates a Pix and sets pix to point to the resulting pointer. Caller must use pixDestroy to free the created Pix. Returns false on error.

ThresholdToPix

@Cast(value="bool")
public boolean ThresholdToPix(@Cast(value="tesseract::PageSegMode")
                                                   int pageseg_mode,
