when debugging last sources downloaded I noticed that cancelling ocr run (when importing vobsubs) doesn't stop the tesseract thread

What steps will reproduce the problem? 1. import vobsub 2. use ocr by tesseract 3. start ocr 4. cancel ocr

What is the expected output? What do you see instead? in the tempdir/ the png files (given to tesseract exe) are still created and deleted although we have stopped the job

What version of the product are you using? On what operating system? SE334 on windows 7 x64

Patchs to apply on SE334-CSharp-SourceCode\Forms\VobSubOcr.cs :

private void ButtonStopClick(object sender, EventArgs e) { _abort = true; _tesseractThread.CancelAsync(); buttonStop.Enabled = false; Application.DoEvents(); progressBar1.Visible = false; labelStatus.Text = string.Empty; }

void TesseractThreadDoWork(object sender, DoWorkEventArgs e) { var bitmap = (Bitmap)e.Argument; if (_tesseractAsyncIndex >= 0 && _tesseractAsyncIndex < _tesseractAsyncStrings.Length) { if (string.IsNullOrEmpty(_tesseractAsyncStrings[_tesseractAsyncIndex]) && bitmap != null) _tesseractAsyncStrings[_tesseractAsyncIndex] = Tesseract3DoOcrViaExe(bitmap, _languageId, "-psm 6"); // 6 = Assume a single uniform block of text.);

            if (((BackgroundWorker)sender).CancellationPending)
            {
                e.Cancel = true;
            }
        }
    }
