ami-ocr ignores --gocr argument

[mdales]

Unlike the --tesseract argument, the --gocr argument isn't used, and the path is always taken as /usr/local/bin/gocr.

You'll also need to check where /usr/local/bin/pngtopnm is if it's used.

Thanks,
Yes pngtopnm is essential; it's exactly the sort of installation issue that we have to deal with. Whereas tesseract reads png , gocr only reads pbm stuff. Converting any images is flaky and this seems the best strategy:

*.png ->pngtopnm -> *.pnm -> gocr

I'll check the gocr argument

The GOCRConverter builds a config string:

	private void runGocr(String inputFilename, String outputFilename) throws InterruptedException {
		List<String> gocrConfig = new ArrayList<>();
		gocrConfig.add(getProgram());
		
		gocrConfig.add("-o");		gocrConfig.add(outputFilename);
		gocrConfig.add("-f");		gocrConfig.add("XML");
		gocrConfig.add("-C"); /* gocrConfig.add("0-9A-Za-z--[]().,%'="); */	gocrConfig.add("0123456789"); // don't think this works
		gocrConfig.add("-m");		gocrConfig.add(String.valueOf(
				/*DONT_DIVIDE_OVERLAPPING + */DONT_CONTEXT_CORRECT + CHARACTER_PACKING));
		
		gocrConfig.add("-i");		gocrConfig.add(inputFilename);
//		System.out.println("GOCR command: "+gocrConfig);
			
		builder = new ProcessBuilder(gocrConfig);
        runBuilderAndCleanUp();
	}

    protected String getPngtopnmPath() {
    	return PNGTOPNM ;
    }

    protected String getProgram() {
    	return gocrPath ;
    }

maybe gocrPath isn't being set in the GOCRConverter - will check tomorrow.

Looks like the value wasn't being used. Have added a transfer in AMIOcrTool #268...

		if (gocrPath != null) {
			GOCRConverter gocrConverter = new GOCRConverter(this);
			if (replaceList.size() > 0) {
				gocrConverter.setReplaceList(replaceList);
			}
			
			try {
				gocrConverter.setGocrPath(gocrPath);
				gocrConverter.setImageFile(imageFile);
				gocrConverter.runGOCR();
			} catch (Exception e) {
				LOG.error("Cannot run GOCR", e);
				return;
			}	
//			processGOCR(imageDir);
