Something is not right:

• the png file provided have a lot more content then two lines
• the uzn file provided seams to be empty or with just 26Bytes
• you did not provide the mimetype

Help me out, this kind of format is new to me, in order to help i must be able to be 100% sure of the data integrity of those files and i need to be able to produce the uzn files, thanks.

Thanks brucardoso2 for introducing me to uzn.
Our lib does support it, but not automated, but it will in our next release. Untill then just parse your uzn and populate the java.awt.Rectangle. Here an example without reading in the uzn file and parsing it:

File imageFile = new File("workingimage004.png");
Tesseract instance = Tesseract.getInstance();  // JNA Interface Mapping
File tessDataFolder = LoadLibs.extractTessResources("tessdata");
instance.setDatapath(tessDataFolder.getAbsolutePath());

//parse the uzn file and create a rectangle obj
Rectangle rect = new Rectangle(600, 213, 1142, 240);
    try {
        String result = instance.doOCR(imageFile, rect);
        System.out.println(result);
    } catch (TesseractException e) {
        System.err.println(e.getMessage());
    }
}
