Error: Not enough memory!

[Xunnozza Vlinx Xenx]

Hello,

i need help!

I get this problem after serveral used the tesseract lib. (Around 450 - 600 runs with tesseract)
I will evaluate the results in different cases. (Testsuit)

I get the error messages: (After 450-600 iteration)

Error: Not enough memory!
"Fatal error encountered!" == NULL:Error:Assert failed:in file ..\..\ccutil\globaloc.cpp, line 75

In jvisualvm look it good. No Memory leak is show up!

This is the code, that i will use very often: (currently work it only 450-600 times)

        String dataPath = dictonaryLanguage.getAbsolutePath();
        TessAPI1.TessBaseAPI handle = TessAPI1.TessBaseAPICreate();
        ByteBuffer buf = ImageIOHelper.convertImageData( image );
        int bpp = image.getColorModel().getPixelSize();
        int bytespp = bpp / 8;
        int bytespl = (int)Math.ceil( image.getWidth() * bpp / 8.0 );

        TessAPI1.TessBaseAPIInit3( handle, dataPath, language );
        TessAPI1.TessBaseAPISetPageSegMode( handle, TessAPI1.TessPageSegMode.PSM_AUTO );
        TessAPI1.TessBaseAPISetImage( handle, buf, image.getWidth(), image.getHeight(), bytespp, bytespl );
        TessAPI1.TessBaseAPIRecognize( handle, null );
        TessAPI1.TessResultIterator ri = TessAPI1.TessBaseAPIGetIterator( handle );
        TessAPI1.TessPageIterator pi = TessAPI1.TessResultIteratorGetPageIterator( ri );
        TessAPI1.TessPageIteratorBegin( pi );

        do {
            Pointer ptr = TessAPI1.TessResultIteratorGetUTF8Text( ri, TessAPI1.TessPageIteratorLevel.RIL_WORD);
            if(ptr == null){
                break;
            }
            String wordText = ptr.getString(0);
            TessAPI1.TessDeleteText(ptr);

            float confidence = TessAPI1.TessResultIteratorConfidence(ri, TessAPI1.TessPageIteratorLevel.RIL_WORD);

            IntBuffer leftB = IntBuffer.allocate( 1);
            IntBuffer topB = IntBuffer.allocate(1);
            IntBuffer rightB = IntBuffer.allocate(1);
            IntBuffer bottomB = IntBuffer.allocate(1);
            TessAPI1.TessPageIteratorBoundingBox(pi, TessAPI1.TessPageIteratorLevel.RIL_WORD, leftB, topB, rightB, bottomB);

            int left = leftB.get();
            int top = topB.get();
            int right = rightB.get();
            int bottom = bottomB.get();

            IntBuffer boldB = IntBuffer.allocate( 1);
            IntBuffer italicB = IntBuffer.allocate(1);
            IntBuffer underlinedB = IntBuffer.allocate(1);
            IntBuffer monospaceB = IntBuffer.allocate(1);
            IntBuffer serifB = IntBuffer.allocate(1);
            IntBuffer smallcapsB = IntBuffer.allocate(1);
            IntBuffer pointSizeB = IntBuffer.allocate(1);
            IntBuffer fontIdB = IntBuffer.allocate(1);

            String fontName = TessAPI1.TessResultIteratorWordFontAttributes(ri, boldB, italicB, underlinedB,monospaceB, serifB, smallcapsB, pointSizeB, fontIdB);
            Rectangle area = new Rectangle( left, top, right-left, bottom-top );
            //and so on ...
        }
        while (TessAPI1.TessPageIteratorNext(pi, TessAPI1.TessPageIteratorLevel.RIL_WORD) == TessAPI1.TRUE);

        //I tried this
        //System.gc();
        //but it doesn't work

Did you try end/delete and create/init a new TessBaseAPI after a number of iterations?

Thanks, for the fast answer, that was the solution.
